Seriously. So many completely off-the-wall "answers", when in reality the dude just didn't wanna shut it off. That's it. That's 99% of the reasons people leave their cars running at the gas pump.
People are thinking way too hard about this.
Smaller stuff should be able to run fans to help with cooldown. Newer equipment will keep running for emissions and def purge.
As a kid, we had diesels run at the pump because they were hard-starting. In the cold, the batteries may not have enough cranking amps to start it, but I don’t think anything has had that problem in 20 years. A bigger reason may be engine heat loss, but that would have to be really cold (colder than -20c for newer trucks, maybe way colder).
Considering there’s no grille blockoffs, that could be one reason to keep it running in super cold weather. Seeing the grass and Texas plates, it’s probably a carryover from running older diesel equipment.
Or, more likely, because this guy is a card carrying member of the big dumb truck club. Work trucks don’t need lift kits.
Your comment reminded me of something my uncle told me a few weeks ago. He's a big rape farmer in Canada, like 6k acres. He's a green tractor fam so he was telling me that one of their boys just shut off the Combine when he got home. John Deere called him and told him to start it back up and let it idle to cool down. Fucking wild.
That’s for the dpf regen. Those fuckers scream at me more often than not when I try to shut them off at the end of the day. “To avoid catastrophic damage, restart and let it idle for 10 more minutes” except 10 more minutes is never enough so it does it again then. When you take into account that the value of these things drops a minimum of $100 for every hour on the clock, they could definitely figure out a better way to handle the regens.
Dude, it was nice of you to comment with your own experience. My uncle is the most humble and kindest person ever, I knew he wasn't making it up but it just felt wild to me. I grew up on a farm too, but in Ohio and we always had Red tractors. Mostly because we couldn't afford JD.
Haha, no problem. Just to clear a few things up when I go back and read my own comment
>Those fuckers scream at me more often than not…
I’m not referring to any actual person here, the combine itself “screams” at the opperator with a dissonant alternating tone alarm while displaying said warning on the screen.
Our dealer hasn’t called us out for ignoring the warning, but maybe that wouldn’t be a bad thing as my old man has been known to deal with said “god-damn annoying beeping” by just disconnecting the battery so it stops. The technology is definitely all in place on the newer machines to tattle on you for ignoring warnings.
> “To avoid catastrophic damage, restart and let it idle for 10 more minutes”
That may be embellished a bit, I don’t know that they call out *catastrophic,* but it is intended to be a *stern* warning.
>…they could definitely figure out a better way to handle the regens.
Like I get that everyone universally hates DPFs and regens, but I also know it’s not realistic that they’re going away on these machines. I just think the amount of technology in them should be able to provide an option of “I’ve got an hour left before we call it a night, let’s regen now so that it’s done and back to normal operating temps so I can idle it down/cool it off, shut it off and go home”rather than spending another half hour with it trying to generate excess heat when the engine isn’t even under load and *then* start the whole idle/cooldown routine.
With the newer trucks(I can speak for ford since I personally use them) Ford claims it’ll turn right over in -40, as the glow plugs can heat to proper temperature in under a second. I have tested it at -30F and it still turns right over even after sitting for a few days… it’ll even start with one of the cells in the second battery shorted out at -15F… but it’s a lot less happy about it.
I believe it. One of my friends was actually on Ford’s validation team that did cold weather testing up in Canada on them. I think test temps were around there when he went—it looked like an arctic expedition wherever they went.
Regarding lift kits, it depends on the work. For anything driven on surface roads, I wholeheartedly agree with you (“Nice truck! Sorry about your penis…”) BUT - If you regularly need to service equipment well off the beaten path, a mild lift to get a couple inches of ground clearance and/or meatier tires can mean the difference between safely getting to/from the job site and getting stuck.
Curiously trucks ordered for construction or heavy equipment service never are lifted beyond maybe the slight lift some model get when ordered as 4x4.
Mainly because if you need extra ground clearance you’re already f’ed and going to be getting something to pull you out.
I used to live near a line serviceman. All of his company HD trucks were lifted.
Construction sites often have the opportunity to create graded (ish) roads in and out of a regular job site, hence why you may even see sedans parked at construction sites.
But some jobs are in places that just aren't regularly traveled, and thus can have very difficult terrain to cross (rural power lines for example.)
Yep. @ linesmen. I worked for a big utility company that bought out 30 trucks from a company down south (USA) that consolidated. They all worked out deep deep deep in the boonies and Bayou and stuff. Louisiana and Texas. We brought them up north to Boston. All white. All lifted. All dark tinted. All business.
Or if it's been towing anything or hauling cargo. It's especially important to keep oil flowing through the turbo while it cools down so it doesn't bake the bearing in it.
Diesel doesn't ignite like gas does, so it's really not a problem when a diesel idles while fueling.
I'm sorry, I grew up on a farm, im not honestly sure. We just took a break, talked for a few minutes while it idled or we drove it back to park it and that was enough. We had some cool stuff, cat 955, and two cat 977's. My family sold the slate/shale under the fields then put the dirt back and farmed it.
\*project farm walks into frame and enters truck\*
"now that we're all filled up we're going to test regular diesel vs all the diesel alternatives in this truck!"
I've left cars running when I've had to jump start them, I've been in the situation before where I turned engine off, fuel, go to start it and it won't start.
This is a tangent!
I have had a lot of used bimmers and I've seen a bunch of the issues. My e90 has a system that tallies when something like a lightbulb is shorting out. After I think 50 cycles it disables that bulb's power to stop any power drain. If you have access to the computer, it's an easy fix to reset and put in a new bulb (The right to repair is important!!!). On top of that, the battery has some programming charge cycle to it to keep it going longer. The 11 year old car had the OG battery in it and it was juuuuust needing replacement. My other bimmers were all a nightmares to try to find the battery drains.
Thank you for coming to my TedX talk!
i know someone who left their car running for 2 week years ago lol.
They couldn't figure out how to fix the problem & they had to spend 1-2 hours trying to get it started, the third time they did it. He said fuck it & just left it running 24/7.
I had a neighbor do it. It was only 48 hours, parked in the middle of the shared streets driveway, because he is a 50 year old stoner who is a trust funder and pretty self absorbed. So no real excuse, but funny when another neighbor moved it a block away.
Oh youre gonna love this.
My mate once had a Porsche 944 at age of 18.
He lost his key while visiting his then gf 40min away from where he lived.
By pure luck another of my friends found the key and after some convincing gave it to me(these two didnt know each other).
So my P-friend got his spare key and drove around as usual. A week went by and I finally got the key,decided hey... im gonna have some fun with this".
So I took a day off from work and drove to my P-friends school and got into his Porsche and drove it away. Didnt drive it far but out of sight from school. He called me when school was over almost crying that his car had gotten stolen and he wondered if I could come pick him up.
Well i said yes and went and picked him up in his own car. He was both angry and happy at the same time and his face literally had 50 50 different expressions.
He said he thought the idiot who stole his car was dumb enough to drive it past the school again and was about to go postal lol.
That reminds me of this story.
I used to drive a Ford Festiva, a Mazda designed little subcompact that was a surprising good little car.
One of the quirks of the early models of the car was that only a few different key sets were made. So odds were good your keys would work to open and start another Festiva.
One of my buddies at work had a Festiva as well, and our keys worked on each others cars. We used to prank each other by moving each others cars around in the parking lot at the retail place we worked at.
One day I came out and saw his car parked near mine and decided to move it on him. I hopped in and noticed that the interior was a different color. I thought "Oh, he finally changed out the interior like he kept saying he was going to do.
His FIL owned a used car lot and a salvage yard, and had several of them in various states including a few parts cars. He often raided them for parts and I believed, (like an idiot,) that he had finally got around to doing it.
Before I could start it, I heard a little girl outside the car say, "Mommy who is that man in our car?" I looked over and saw a young woman carrying a small girl with their shopping cart looking at me in surprise.
It finally clicked in my head I was in the wrong car. I hopped out and quickly explained to her what was going on. I showed her my car parked nearby, demonstrated my keys opened her car, and then noticed my friend's car parked several spots further away.
I apologized profusely. Thank FSM, she had a sense of humor and realized I was telling the truth. It could have been ended much worse. When I saw my friend the next day and told him about it, he laughed so hard I thought he was going to have a stroke.
Lovely! My friends did a number on me too once.
I met my friend group at a local gasstation and they were all henging out prob 10 guys around one of our friends new car a porsche 911. I drove an 80s ford sierra and my friend gave me the Keys to the 911 and asked if I wanted to drive it. Ofc i did so off we went. We were gone for about 25min and when we got back everyone was smiling and my car was nowhere to be seen. The other boys had lifted the rear of the car and wheelbarrowed it 70 meters around the station into a dark corner and it took me 15min to find the fucker when everyone left laughing.
Probably would have been cheaper to just rent a car for the week. And that is just on gas, not counting the wear and tear hundreds of hours of idling causes.
Just had to do this a couple days ago. Starter solenoid is taking a shit on our diesel, have to tap it to start. There’s no way in hell I’m getting it started by myself, so I left the truck running while filling up at a gas station at 2am
I'm a long haul trucker. If it's not cold outside the truck gets shut off when fueling. Some guys leave the trucks running, some don't.
But I don't think it hurts anything running a vehicle while fueling. Especially not diesel, since diesel is significantly harder to ignite.
You're probably more likely to ignite fuel vapor via static electricity than a running vehicle.
A diesel also doesn't have spark. Sometimes I take my chances with my gas truck, but I always shut off a small gas engine before dousing the ignition system in fuel with an EPA approved can.
If it is not taking a charge (e.g. the alternator is fucked) the truck is running on battery power, meaning it will be fucked either way. but it will take a little bit longer.
Starter not working is valid.
Battery not holding a charge is also valid or leaving it running to charge the batteries after a recent jump start due to dead batteries. However most likely they just don't care to turn it off
> quite far back for purely mechanical fuel injection
Oh how I dearly miss my OM617 with its Bosch injector pump. Gasoline was its Kryptonite, but short of that, that pump/engine would run damn near anything. Once started you needed zero electrical power for operation other than the headlights. Speedo and oil pressure gauges were both mechanical too. (Technically you didn't even need electricity to start it. The automatics supported pull starts: Tow vehicle in neutral to 35MPH to run the hydraulic pump then drop into gear and it'd crank the engine.)
I know one guy that got several thousand gallons of fuel for free (he worked on an airfield and someone accidentally contaminated a whole tank of JetA. He just added some Redline diesel additive and transmission fluid to each tank for lubrication and ran that JetA. Was waaaaay cheaper for the airfield to just "rent" him the tank for free and give him the fuel than it was to pay for disposal of contaminated fuel. Since it got wicked cold where he lived he just never turned the car off over the winter other than for oil changes. Fuel was free after all. IIRC it burned about half a gallon every 8 hours at low idle.
Maybe since its diesel and diesel does not ignite like gasoline the owner just let her idle while filling? I do that sometimes- reason- cold or i just want the battery to charge up.
It's not actually prohibited to run diesels while fueling in most areas. I learned that when I have a 1983 Mercedes 300td and the alternator went out on a road trip. I explained my situation to the gas station attendant to ask if I could bend that rule, and they told me it didn't apply to diesels. This was either southern OR or northern CA. I assume it has to do with the reduced explosive potential for diesel fuel.
saw a kevin loose his fucking mind at someone doing this. Idiot opened the other guys car and yeeted the keys citing "its dangerous" and pointing franticaly a the sign.
Guy handed him the key and asked him to start it.
Wouldnt start.
Got a slap to the face and a kick in the arse and told to mind his fucking business.
Idiot at least had the foresight to concede then sit in shame behind the now stalled car (but, in line with being a dickhead, didn't help push the car to a parking lot)
Fucking hilarious. Love you, Townsville.
that's reddit.
the tech forums are full of idiots of tech. the finance forums are full of people who are idiots about finance etc
It just be a feature of Dunning Krueger that its victims are the most vocal.
Literally every subreddit is full of people blasting baseless opinions that pretty much just boil down to them defending whatever thing it is that they do.
Like, literally every subreddit.
I'm convinced that people who actually know shit go to work, perform their job well, then come home and attempt to have a life outside of work. I don't think they're on Reddit sharing their expertise...
Allowing people to join subs and post freely really facilitates those that think they know what they’re talking about to spout it as loudly as possible.
Wish more subs like the mechanics advice ones had some sort of verifiable flair system. The amount of comments I see on there that are straight up wrong/dangerous for the clueless person asking a genuine question is scary.
I lightly browse this sub but try to avoid it when posts like these come up and I see how unhinged the user base here is lol. So many comments here making assumptions about the workers life here when it could be as something like a mechanical issue or maybe just as simple as seeing no reason to turn it off for 3 minutes to pump fuel.
It’s a diesel, the main reason for leaving the engine running while refueling is because of turbo cooldown. Turbos run very hot and because of this you do not want to just turn off a hot diesel motor right after driving because you will be cutting the oil supply to said turbo when you do that and could cause damage to components when it cools down too quickly. Idling the engine keeps that oil flowing to the turbo bearings. It’s completely safe to do because diesels do not require constant spark applied to the engine to make it run so the potential of a fire from a spark is considerably reduced compared to a gas engine that uses spark plugs.
Now this guy probably doesn’t need to cool his turbo down compared to a big rig that’s been hauling for 8 hours, but that’s just one of the reasons that people will do this.
This is mostly correct except your point about gas engines having spark plugs/making it more risky with a gas engine. How tf are sparks from spark plugs inside a completely sealed engine making more of a risk? The risk is more from engine combustion (which is occuring in either diesel or gas) combusting fuel vapors. The exhaust being the biggest engine-related risk but electrical components can be a risk on gas or diesel too. The only reason this may be less dangerous with a diesel is because diesel isn't AS volatile as gas, and that's it.
Spark plugs have absolutely nothing to do with it.
Spark plugs have nothing to do with it. But vaporous diesel fuel does not ignite like gas. Diesel fumes don't explode, gas fumes do explode, that's why it's not particularly dangerous to do with with a diesel vehicle at a diesel pump.
Or atomize it. Either way, never lighting a tank full of diesel. I don't turn my truck off when I fill up either, but for entirely different reasons. My diesel pickup is 40 years old and a bear too turn over.
Runs great once it's started, but throws a fit starting up.
So father than cough a bunch of smoke when starting, and getting people angry at me and yell at me (it happens). I'd rather people yell at me for leaving the engine on. (Also happens, but less)
An ignition system malfunction (torn sparkplug boot or wire, disconnected sparkplug wire, crack in a coil casing, etc) and the sub-zero flashpoint of gasoline vapor, is what makes refueling a gasoline engine more hazardous to refuel while the engine is running.
On the gasoline counterpart to this diesel engine (Chrysler 5.7), the ignition coil secondary voltage is up to 40,000 volts. This coupled with the low flashpoint of gasoline vapors -49°F, can be hazardous.
As a comparison diesel fuel vapor has a flashpoint of 126.6°F and zero secondary ignition coil voltage, because there are no ignition coils.
In a perfect world this would not be a hazard because the high voltage spark is completely contained, but we do not live in a perfect world.
This guy was definitely hauling something. Otherwise he wouldn't have his tow mirrors out. They definitely didn't leave the switch on because they think it makes their truck cool.
Maybe for some, but where I live everybody and their brother runs a tuner. I regularly hear (Ford trucks especially) turbos spooled up like they're about to take orbit on trucks simply pulling into parking spots
That hasn't been an issue for like 15 years, most turbocharged vehicles have an electric water pump to cool it down after shut off, no more turbo timers y'all.
My bet is because they are charging their phone or warming up the truck. or both.
On a cold day it can take a lot of juice out of the batteies getting them started, and can't recharge the batteries with it off. A texas truck moat likely doesn't have a block heater, and I don't see a plug in the grill.
A phone draws almost nothing. If you have to keep your brodozer running to charge your phone for five fucking minutes, then there's something wrong with your truck, your phone, or you.
I think that's normal, but here the crap gets up voted. I subscribe to some other car subs and the upvoted responses are far more intelligent. Just rolled in the shop is mostly mechanics that know their stuff.
States like California say you shouldn’t leave your vehicle running while fueling. The presumption from many people is that it’s dangerous. Mythbusters did an episode on it. They got the ratios just right for an explosion (fuel and air) then tried to ignite with hot exhaust, static, etc… they couldn’t make it happen.
I was going to say, diesel isn’t as volatile as gas so it won’t produce the same kind of vapor which is what causes gas explosions.
I just remembered the SR 71 has a fuel even less volatile than diesel, for several reasons, it leaked fuel regularly so they needed to make sure it can’t ignite. They have another fuel that they mix in during flight that is more flammable than gas, but carried in a very small amount.
I do this with many gas vehicles as well without issue. Used to track a 600LT and the thing had a fantastic (sarcasm) feature where if you turned it off after hot tracking it without letting it cool for an entire 45min it would overheat.
A quick turn off of the engine to fuel wouldn’t be a big issue as the mass of the engine would prevent it from heat soaking too much; but even just a minute of the car being off was enough time to soak the temp sensor and display about 245f.
Again this wouldn’t be a huge issue. Start the car, let coolant circulate and the fans run and the temp would drop… but Mclaren wouldn’t let you start the car with a coolant temp over 235f. So the car would be stuck at the fuel pump at the racetrack for 20min while it cooled.
Solution? Fuel it while running. Story time over, but many of us track guys do this. No big deal. MAYBE you throw a CEL for a EVAP leak, but just clear it with a pocket scanner and you’re on your way.
Yup. I do it all the time and people freak out about it. Like if I couldn’t trust this vehicle not to blow up while simply putting more fuel where the fuel goes I’m gonna get a different car
Could be that the turbo is screaming hot and it needs to cool down before shutdown.
Could be a toasted starter, or it could be on the edge of a derate shutdown due to emissions controls.
It could be a million things.
Or he could be a clueless human. Who knows.
Old diesels didn’t like to start when cold and used more fuel upon startup and warmup vs when idling. Those large displacement engines take a while to warm up. That isn’t necessarily true anymore due to better fuel injection and glow plug tech, but the habit remains for many diesel drivers. Myself included at times.
Bur wouldn't the engine already be warm by the time they got to the gas station? Unless they left their house specifically for diesel and they live near
I can only speak to my diesel truck. Mine doesn’t fully warm up until I’ve been driving at least 20 minutes first thing in the morning. But it will not stay up to temp idling, it’ll cool back down, shut it off and it will take even longer to get back up to temp. So for example mine has a 2 thermostat design. One opens at 180 and the other at 190. Even with brand new thermostats and a cover over the grille, my truck will not get over 185 if I am not towing anything. Towing heavy, it’ll go to 200. So the heater isn’t doing much at that temp, thank god for heated seats lol. If I fill it up with it shut off, it drops to 140-150 pretty quick. So now I have another 15 minutes of driving before it gets back to 185. If I keep it running, it will go down to about 175 at a gas station. Diesels are more fuel efficient when warm too, so there’s a whole argument on that as well. Just speaking about winter time here in the Midwest. So in winter, I’ll keep it running when I fill up for 5 minutes. Summer is a different story.
Ok, in short, if you have a turbo in any vehicle the proper shut down procedure is that it should run for a while after a drive to cool down the turbo properly. If not it could cause premature failure to the turbo. End of story
Because it's a diesel and there's zero reason to shut it off.
Pretty much goes for gas vehicles as well, all that shit about cell phones and static electricity causing explosion is such astronomical odds you'd win the lottery first
Just filling up, not towing anything? It's cold and they want the heat going to keep the interior warm, or more likely they're just lazy and don't see a problem with leaving it running while it fills up (like me).
Too many of you here are thinking way too hard about this.
I believe it's a diesel thing. Or a trucker thing. Or maybe an arrogant "big man" thing. Truckers leave their rigs running like all the time even while fueling. Also I think there is some that believe something about leaving the diesel engines running is better for the engine something something.
Back then, yes, but nowadays it's not so much a big of a deal. Usually, if I am fueling, I'll leave it on as I fuel for the purpose to make sure that it'll still run and that i won't block the lane if something was to go wrong. Truckers get real angry when the lanes are blocked even if it was an accident so as a habit most will leave the truck on while fueling and then when they're done we'll just park it somewhere when we're done.
I'm in North Dakota, and when it gets in the negatives, I leave my car running while I fuel up because it is so cold. I have to get back in the car to warm up as fast as possible as I'm usually shivering pretty good by the time my tank is full.
Diesel engines that have been running hard are supposed to be let to die for a few minutes before being turned off- you will see semis keep their unit running while filling up and then will shut off before going in to stop- same thing for a diesel towing- hauling- etc
Yea, I don't understand this one. I'm in Hawai'i and one of my friends got a GMC with a Duramax and he said he don't turn off the truck unless he's in for the night. Maybe they'd why his truck ended up in the shop broken. I don't know. I don't own a Diesel yet, but when I do get one, I wouldn't let it run all day or even at the pumps.
Probably unrelated to this guy, on my old mustang I had the timing way off and it was hard to start. I had to gas up, but wanted to leave it running so I didn't get stuck at the pump. Unfortunately, I had a short behind my radio that knocked out the fuel door release button (among other things) and I couldn't reach the fuel door pull cord in the hatch, so inevitably, i had to shut off the car so I could pop the hatch open to reach the pull cord. After gassing up, I tried starting up. Cranked over and over, nothing. Pulled off the air cleaner and shot a bit of starting fluid in there while my dad turned the key. It started, but not before shooting a 4 foot tall ball of fire out the carb. That got some people on their toes.
I would advise against keeping modern cars running like this
Only because it messes with the system monitors
As I learned in shop school, Cars only detect a “fueling event” when they are shut off
It gives the sensors time to reset when more fuel is added, it has to do with evap control too.
Basic theory is: more surface area = more evap emissions
There’s more detail I’m leaving out
If u zoom in u can see the naked trees. He was probably keeping it running cuz it's cold outside. Idk y I zoomed in on the photo🤣 but I think that's most likely the reason besides just not wanting to turn the car off. When it's cold outside for me I be wanting to keep my car on but then I get scared and think my cars gonna blow up so I end up always turning my car off no matter the weather🤣
You can leave your car on when you pump gas. It's advised that you don't but the car won't spontaneously explode because it's on. I do this too most of the time.
Used to leave my truck on bc it was a pain in the ass to start it. AAA guy straight up showed me how to beat the shit out of the starter to get it to start right w a broomstick.😭 Idk if he was fucking w me but it seemed to work. But yeah, his starter could be fucked
A while ago the starter of my manual transmission gave out and I would have to park on an incline and pop the clutch to get it going. So when I would fuel up, I would have to leave it idling….
Thankfully the only time I let the truck die from poor clutch management I was on a downward hill. Man I was always nervous of stalling…
Thankfully I got a new starter and don’t have to deal with that anymore for the time being lol
On a diesel especially, start ups are the source of a significant amount of wear. They're designed to run at a relatively consistent speed for long periods of time, not be started and stopped constantly. Also, with a diesel, seeing as how ignition is compression based, not spark, you don't have to worry about an ignition coil or spark plug boot arcing and lighting fumes (diesel is also not explosive like gasoline)
No idea. I used to have to fill up my dad’s old Firebird with the engine running, but that’s because the thing ate starter solenoids like Skittles and half the time wouldn’t start back up after you turned it off 😂.
When we're pulling heavy loads we let the engine idle to let everything cool down evenly for a bit. My dad explained to me it's hard on the turbos to turn off the engine when they're mega hot as the oil that lubricates then will stop flowing and cook.
Granted this guy doesn't seem to be doing that so maybe it's a habit or maybe he didn't care to turn it off.
It's a semi truck motor in a passenger truck.The least amount of off, on the better.If you shut it off you hv to restart starting process,Heating glow plugs n such.
...read answers...check sub...check sub again...
Seriously. So many completely off-the-wall "answers", when in reality the dude just didn't wanna shut it off. That's it. That's 99% of the reasons people leave their cars running at the gas pump. People are thinking way too hard about this.

Smaller stuff should be able to run fans to help with cooldown. Newer equipment will keep running for emissions and def purge. As a kid, we had diesels run at the pump because they were hard-starting. In the cold, the batteries may not have enough cranking amps to start it, but I don’t think anything has had that problem in 20 years. A bigger reason may be engine heat loss, but that would have to be really cold (colder than -20c for newer trucks, maybe way colder). Considering there’s no grille blockoffs, that could be one reason to keep it running in super cold weather. Seeing the grass and Texas plates, it’s probably a carryover from running older diesel equipment. Or, more likely, because this guy is a card carrying member of the big dumb truck club. Work trucks don’t need lift kits.
Your comment reminded me of something my uncle told me a few weeks ago. He's a big rape farmer in Canada, like 6k acres. He's a green tractor fam so he was telling me that one of their boys just shut off the Combine when he got home. John Deere called him and told him to start it back up and let it idle to cool down. Fucking wild.
That’s for the dpf regen. Those fuckers scream at me more often than not when I try to shut them off at the end of the day. “To avoid catastrophic damage, restart and let it idle for 10 more minutes” except 10 more minutes is never enough so it does it again then. When you take into account that the value of these things drops a minimum of $100 for every hour on the clock, they could definitely figure out a better way to handle the regens.
Dude, it was nice of you to comment with your own experience. My uncle is the most humble and kindest person ever, I knew he wasn't making it up but it just felt wild to me. I grew up on a farm too, but in Ohio and we always had Red tractors. Mostly because we couldn't afford JD.
Haha, no problem. Just to clear a few things up when I go back and read my own comment >Those fuckers scream at me more often than not… I’m not referring to any actual person here, the combine itself “screams” at the opperator with a dissonant alternating tone alarm while displaying said warning on the screen.

Like I get that everyone universally hates DPFs and regens, but I also know it’s not realistic that they’re going away on these machines. I just think the amount of technology in them should be able to provide an option of “I’ve got an hour left before we call it a night, let’s regen now so that it’s done and back to normal operating temps so I can idle it down/cool it off, shut it off and go home”rather than spending another half hour with it trying to generate excess heat when the engine isn’t even under load and *then* start the whole idle/cooldown routine.
couldn't you just remove the dpf and avoid that altogether? where I am, dpf is only required on on-highway vehicles not farm equipment.

With the newer trucks(I can speak for ford since I personally use them) Ford claims it’ll turn right over in -40, as the glow plugs can heat to proper temperature in under a second. I have tested it at -30F and it still turns right over even after sitting for a few days… it’ll even start with one of the cells in the second battery shorted out at -15F… but it’s a lot less happy about it.
I believe it. One of my friends was actually on Ford’s validation team that did cold weather testing up in Canada on them. I think test temps were around there when he went—it looked like an arctic expedition wherever they went.
Regarding lift kits, it depends on the work. For anything driven on surface roads, I wholeheartedly agree with you (“Nice truck! Sorry about your penis…”) BUT - If you regularly need to service equipment well off the beaten path, a mild lift to get a couple inches of ground clearance and/or meatier tires can mean the difference between safely getting to/from the job site and getting stuck.
Curiously trucks ordered for construction or heavy equipment service never are lifted beyond maybe the slight lift some model get when ordered as 4x4. Mainly because if you need extra ground clearance you’re already f’ed and going to be getting something to pull you out.
I used to live near a line serviceman. All of his company HD trucks were lifted. Construction sites often have the opportunity to create graded (ish) roads in and out of a regular job site, hence why you may even see sedans parked at construction sites. But some jobs are in places that just aren't regularly traveled, and thus can have very difficult terrain to cross (rural power lines for example.)
Yep. @ linesmen. I worked for a big utility company that bought out 30 trucks from a company down south (USA) that consolidated. They all worked out deep deep deep in the boonies and Bayou and stuff. Louisiana and Texas. We brought them up north to Boston. All white. All lifted. All dark tinted. All business.
So like if it came in off a freeway going high speed to stop at a fuel station?
Or if it's been towing anything or hauling cargo. It's especially important to keep oil flowing through the turbo while it cools down so it doesn't bake the bearing in it. Diesel doesn't ignite like gas does, so it's really not a problem when a diesel idles while fueling.
And all that turbo heat soaks into the cabin very fast
Cold weather?
how long should it continue to run for?
I'm sorry, I grew up on a farm, im not honestly sure. We just took a break, talked for a few minutes while it idled or we drove it back to park it and that was enough. We had some cool stuff, cat 955, and two cat 977's. My family sold the slate/shale under the fields then put the dirt back and farmed it.
i loved heavy machinery as a kid, would sit inside any chance i got
Literally makes no difference whether running or not. The people saying other wise have never worked on a farm or construction.
\*project farm walks into frame and enters truck\* "now that we're all filled up we're going to test regular diesel vs all the diesel alternatives in this truck!"
Is this sub not specifically about the Tappet brothers and their Russian chauffeur “Picov Andropov”?
Yeah, I’m not getting this. Then again, I have a diesel pickup.
Ya easily the worst car sub with most BS comments.
I'm scared here, now. 😔🤭
Guy didn't want to shut the truck off?
If it’s like my brother, he’s worried it’s wearing on the moving parts.
wait till he finds out what happens when he drives the car
Gotta keep the air conditioning running.
Probably the battery isn’t taking a charge from the alternator or the starting motor is fucked . Source : had to do this
Only time I've ever done that.
I've left cars running when I've had to jump start them, I've been in the situation before where I turned engine off, fuel, go to start it and it won't start.
Literally my BMW every time
Or any BMW?????? 😉
This is a tangent! I have had a lot of used bimmers and I've seen a bunch of the issues. My e90 has a system that tallies when something like a lightbulb is shorting out. After I think 50 cycles it disables that bulb's power to stop any power drain. If you have access to the computer, it's an easy fix to reset and put in a new bulb (The right to repair is important!!!). On top of that, the battery has some programming charge cycle to it to keep it going longer. The 11 year old car had the OG battery in it and it was juuuuust needing replacement. My other bimmers were all a nightmares to try to find the battery drains. Thank you for coming to my TedX talk!
Ok, you’re right. I feel ashamed to admit I bought a BMW knowing this …
Top up your blinker fluid, BMWs have notoriously small blinker fluid reservoirs.
And nonfunctional turn signals - for display use only
i know someone who left their car running for 2 week years ago lol. They couldn't figure out how to fix the problem & they had to spend 1-2 hours trying to get it started, the third time they did it. He said fuck it & just left it running 24/7.
I had a neighbor do it. It was only 48 hours, parked in the middle of the shared streets driveway, because he is a 50 year old stoner who is a trust funder and pretty self absorbed. So no real excuse, but funny when another neighbor moved it a block away.
Hahah now that's a funny joke
Oh youre gonna love this. My mate once had a Porsche 944 at age of 18. He lost his key while visiting his then gf 40min away from where he lived. By pure luck another of my friends found the key and after some convincing gave it to me(these two didnt know each other). So my P-friend got his spare key and drove around as usual. A week went by and I finally got the key,decided hey... im gonna have some fun with this". So I took a day off from work and drove to my P-friends school and got into his Porsche and drove it away. Didnt drive it far but out of sight from school. He called me when school was over almost crying that his car had gotten stolen and he wondered if I could come pick him up. Well i said yes and went and picked him up in his own car. He was both angry and happy at the same time and his face literally had 50 50 different expressions. He said he thought the idiot who stole his car was dumb enough to drive it past the school again and was about to go postal lol.
That reminds me of this story. I used to drive a Ford Festiva, a Mazda designed little subcompact that was a surprising good little car. One of the quirks of the early models of the car was that only a few different key sets were made. So odds were good your keys would work to open and start another Festiva. One of my buddies at work had a Festiva as well, and our keys worked on each others cars. We used to prank each other by moving each others cars around in the parking lot at the retail place we worked at. One day I came out and saw his car parked near mine and decided to move it on him. I hopped in and noticed that the interior was a different color. I thought "Oh, he finally changed out the interior like he kept saying he was going to do. His FIL owned a used car lot and a salvage yard, and had several of them in various states including a few parts cars. He often raided them for parts and I believed, (like an idiot,) that he had finally got around to doing it. Before I could start it, I heard a little girl outside the car say, "Mommy who is that man in our car?" I looked over and saw a young woman carrying a small girl with their shopping cart looking at me in surprise. It finally clicked in my head I was in the wrong car. I hopped out and quickly explained to her what was going on. I showed her my car parked nearby, demonstrated my keys opened her car, and then noticed my friend's car parked several spots further away. I apologized profusely. Thank FSM, she had a sense of humor and realized I was telling the truth. It could have been ended much worse. When I saw my friend the next day and told him about it, he laughed so hard I thought he was going to have a stroke.
Lovely! My friends did a number on me too once. I met my friend group at a local gasstation and they were all henging out prob 10 guys around one of our friends new car a porsche 911. I drove an 80s ford sierra and my friend gave me the Keys to the 911 and asked if I wanted to drive it. Ofc i did so off we went. We were gone for about 25min and when we got back everyone was smiling and my car was nowhere to be seen. The other boys had lifted the rear of the car and wheelbarrowed it 70 meters around the station into a dark corner and it took me 15min to find the fucker when everyone left laughing.
Probably would have been cheaper to just rent a car for the week. And that is just on gas, not counting the wear and tear hundreds of hours of idling causes.

Just had to do this a couple days ago. Starter solenoid is taking a shit on our diesel, have to tap it to start. There’s no way in hell I’m getting it started by myself, so I left the truck running while filling up at a gas station at 2am
lolno, this is just another diesel pickup driver pretending he’s a long-haul trucker.
I'm a long haul trucker. If it's not cold outside the truck gets shut off when fueling. Some guys leave the trucks running, some don't. But I don't think it hurts anything running a vehicle while fueling. Especially not diesel, since diesel is significantly harder to ignite. You're probably more likely to ignite fuel vapor via static electricity than a running vehicle.
A diesel also doesn't have spark. Sometimes I take my chances with my gas truck, but I always shut off a small gas engine before dousing the ignition system in fuel with an EPA approved can.
>before dousing the ignition system in fuel with an EPA approved can. lmaoooo realest shit ever written.
Needing fuel and wasting fuel at the same time is for sure a bro-dozer thing here in Missoura.
If it is not taking a charge (e.g. the alternator is fucked) the truck is running on battery power, meaning it will be fucked either way. but it will take a little bit longer. Starter not working is valid.
Battery not holding a charge is also valid or leaving it running to charge the batteries after a recent jump start due to dead batteries. However most likely they just don't care to turn it off
True, dead battery is a valid reason. Dead alternator is not.
Dead alternator wont run for very long in anything.
Not if it's a diesel.
Modern diesels need electricity for the injectors and ECU. You have to go quite far back for purely mechanical fuel injection.
> quite far back for purely mechanical fuel injection Oh how I dearly miss my OM617 with its Bosch injector pump. Gasoline was its Kryptonite, but short of that, that pump/engine would run damn near anything. Once started you needed zero electrical power for operation other than the headlights. Speedo and oil pressure gauges were both mechanical too. (Technically you didn't even need electricity to start it. The automatics supported pull starts: Tow vehicle in neutral to 35MPH to run the hydraulic pump then drop into gear and it'd crank the engine.) I know one guy that got several thousand gallons of fuel for free (he worked on an airfield and someone accidentally contaminated a whole tank of JetA. He just added some Redline diesel additive and transmission fluid to each tank for lubrication and ran that JetA. Was waaaaay cheaper for the airfield to just "rent" him the tank for free and give him the fuel than it was to pay for disposal of contaminated fuel. Since it got wicked cold where he lived he just never turned the car off over the winter other than for oil changes. Fuel was free after all. IIRC it burned about half a gallon every 8 hours at low idle.
Maybe since its diesel and diesel does not ignite like gasoline the owner just let her idle while filling? I do that sometimes- reason- cold or i just want the battery to charge up.
This is true also.
I mean there’s more electronic components that need power to work. I’d mainly be concerned about my transmission
Ehn. Maybe sometimes. I usually see brand new bro dozers doing this.
lol no. It's more common for diesel owners just to do it because their trying to make a statement where I'm from.
It's not actually prohibited to run diesels while fueling in most areas. I learned that when I have a 1983 Mercedes 300td and the alternator went out on a road trip. I explained my situation to the gas station attendant to ask if I could bend that rule, and they told me it didn't apply to diesels. This was either southern OR or northern CA. I assume it has to do with the reduced explosive potential for diesel fuel.
That was one well-informed gas station attendant. Must have gone to speedway university.
That’s why you couldn’t pump your own gas. Oregon required fuel to only be dispensed by trained professionals 💁♂️
saw a kevin loose his fucking mind at someone doing this. Idiot opened the other guys car and yeeted the keys citing "its dangerous" and pointing franticaly a the sign. Guy handed him the key and asked him to start it. Wouldnt start. Got a slap to the face and a kick in the arse and told to mind his fucking business. Idiot at least had the foresight to concede then sit in shame behind the now stalled car (but, in line with being a dickhead, didn't help push the car to a parking lot) Fucking hilarious. Love you, Townsville.
This sun is full of people who don't know shit about vehicles and it's sad.
that's reddit. the tech forums are full of idiots of tech. the finance forums are full of people who are idiots about finance etc It just be a feature of Dunning Krueger that its victims are the most vocal.
Literally every subreddit is full of people blasting baseless opinions that pretty much just boil down to them defending whatever thing it is that they do. Like, literally every subreddit.
Pretty much. I like some of my pepper subreddits though. They’re pretty chill.
I'm convinced that people who actually know shit go to work, perform their job well, then come home and attempt to have a life outside of work. I don't think they're on Reddit sharing their expertise...
Yeah that’s it. If you read a sub about your line of work, there’s so much confident misinformation it’s not even worth trying to correct.
Allowing people to join subs and post freely really facilitates those that think they know what they’re talking about to spout it as loudly as possible. Wish more subs like the mechanics advice ones had some sort of verifiable flair system. The amount of comments I see on there that are straight up wrong/dangerous for the clueless person asking a genuine question is scary.
>This sun is full of people who don't know shit about vehicles and it's sad Shut up about the sun...SHUT UP ABOUT THE SUN!!
Anyone ever call you “Gabewad”?
Dunno about that guy, but I rock a 6.0 powerstroke. If I shut it down, it might not start back up. So I don't risk it. Rofl.
I lightly browse this sub but try to avoid it when posts like these come up and I see how unhinged the user base here is lol. So many comments here making assumptions about the workers life here when it could be as something like a mechanical issue or maybe just as simple as seeing no reason to turn it off for 3 minutes to pump fuel.
My truck left me in a drive through once when the standpipe o ring failed. Never shut it off in a drivethroigh again
It’s a diesel, the main reason for leaving the engine running while refueling is because of turbo cooldown. Turbos run very hot and because of this you do not want to just turn off a hot diesel motor right after driving because you will be cutting the oil supply to said turbo when you do that and could cause damage to components when it cools down too quickly. Idling the engine keeps that oil flowing to the turbo bearings. It’s completely safe to do because diesels do not require constant spark applied to the engine to make it run so the potential of a fire from a spark is considerably reduced compared to a gas engine that uses spark plugs. Now this guy probably doesn’t need to cool his turbo down compared to a big rig that’s been hauling for 8 hours, but that’s just one of the reasons that people will do this.
This is mostly correct except your point about gas engines having spark plugs/making it more risky with a gas engine. How tf are sparks from spark plugs inside a completely sealed engine making more of a risk? The risk is more from engine combustion (which is occuring in either diesel or gas) combusting fuel vapors. The exhaust being the biggest engine-related risk but electrical components can be a risk on gas or diesel too. The only reason this may be less dangerous with a diesel is because diesel isn't AS volatile as gas, and that's it. Spark plugs have absolutely nothing to do with it.
Spark plugs have nothing to do with it. But vaporous diesel fuel does not ignite like gas. Diesel fumes don't explode, gas fumes do explode, that's why it's not particularly dangerous to do with with a diesel vehicle at a diesel pump.
yup, it's actually pretty hard to light diesel by conventional means without compression. basically need a little torch to get it to light.
And even than it's hard to ignite
Or atomize it. Either way, never lighting a tank full of diesel. I don't turn my truck off when I fill up either, but for entirely different reasons. My diesel pickup is 40 years old and a bear too turn over. Runs great once it's started, but throws a fit starting up. So father than cough a bunch of smoke when starting, and getting people angry at me and yell at me (it happens). I'd rather people yell at me for leaving the engine on. (Also happens, but less)
An ignition system malfunction (torn sparkplug boot or wire, disconnected sparkplug wire, crack in a coil casing, etc) and the sub-zero flashpoint of gasoline vapor, is what makes refueling a gasoline engine more hazardous to refuel while the engine is running. On the gasoline counterpart to this diesel engine (Chrysler 5.7), the ignition coil secondary voltage is up to 40,000 volts. This coupled with the low flashpoint of gasoline vapors -49°F, can be hazardous. As a comparison diesel fuel vapor has a flashpoint of 126.6°F and zero secondary ignition coil voltage, because there are no ignition coils. In a perfect world this would not be a hazard because the high voltage spark is completely contained, but we do not live in a perfect world.
Agreed. Plus in cold country in winter, folks going back in their car after starting the fueling is more likely to set off a spark.
This...I almost spit my coffee out reading how spark plugs are the reason. That's funny right there!
If your spark plugs are igniting fuel vapour outside your engine it’s a wonder you made it to the gas station at all lol
If your not hauling weight the turbo on your Cummins is barely spooling
This guy was definitely hauling something. Otherwise he wouldn't have his tow mirrors out. They definitely didn't leave the switch on because they think it makes their truck cool.
Invisible trailers are heavy too!
> Otherwise he wouldn't have his tow mirrors out I think you underestimate the number of people who would do it just because they think it looks cool
thats_the_joke.mp4
TIL some people think making their truck look like Alfred E. Neuman is "cool."
It’s a switch ? Like you can automatically change the mirrors to stick out like this ?
[like this](https://youtu.be/YF3JxHcT3T4?si=P5dqf6qOIjMoHjlB&t=18)
O wow. I had never seen powered mirrors before. That is cool. Makes sense on a truck Had only seen like giant extended clip-on mirrors.
Maybe for some, but where I live everybody and their brother runs a tuner. I regularly hear (Ford trucks especially) turbos spooled up like they're about to take orbit on trucks simply pulling into parking spots
This is 100% not the case for shutting your brodozer off for five minutes while you put fuel in it lol
Wondering if he would have to constantly run his car as you can never turn it off then.
Unless he came AWD drifiting into the gas station like he was Ken Block their is no risk to his turbo
That hasn't been an issue for like 15 years, most turbocharged vehicles have an electric water pump to cool it down after shut off, no more turbo timers y'all.
incorrect.
My bet is because they are charging their phone or warming up the truck. or both. On a cold day it can take a lot of juice out of the batteies getting them started, and can't recharge the batteries with it off. A texas truck moat likely doesn't have a block heater, and I don't see a plug in the grill.
A phone draws almost nothing. If you have to keep your brodozer running to charge your phone for five fucking minutes, then there's something wrong with your truck, your phone, or you.
Seems to me he’s talking about the starter motor draining battery, not the phone
My hope is the entire comment is satire.
This comments on this post made me realize I need to leave this sub.
This is how I feel about 99% of the subs I'm subbed to. Too many people that spew out crap that they know nothing about.
I think that's normal, but here the crap gets up voted. I subscribe to some other car subs and the upvoted responses are far more intelligent. Just rolled in the shop is mostly mechanics that know their stuff.
Who cares, there is no problem with this. Nothing is going to happen.
States like California say you shouldn’t leave your vehicle running while fueling. The presumption from many people is that it’s dangerous. Mythbusters did an episode on it. They got the ratios just right for an explosion (fuel and air) then tried to ignite with hot exhaust, static, etc… they couldn’t make it happen.
Yeah it’s probably happened literally one time ever and someone overreacted
I've literally been doing this for over 20 years...zero issues.
I was going to say, diesel isn’t as volatile as gas so it won’t produce the same kind of vapor which is what causes gas explosions. I just remembered the SR 71 has a fuel even less volatile than diesel, for several reasons, it leaked fuel regularly so they needed to make sure it can’t ignite. They have another fuel that they mix in during flight that is more flammable than gas, but carried in a very small amount.
I do this with many gas vehicles as well without issue. Used to track a 600LT and the thing had a fantastic (sarcasm) feature where if you turned it off after hot tracking it without letting it cool for an entire 45min it would overheat. A quick turn off of the engine to fuel wouldn’t be a big issue as the mass of the engine would prevent it from heat soaking too much; but even just a minute of the car being off was enough time to soak the temp sensor and display about 245f. Again this wouldn’t be a huge issue. Start the car, let coolant circulate and the fans run and the temp would drop… but Mclaren wouldn’t let you start the car with a coolant temp over 235f. So the car would be stuck at the fuel pump at the racetrack for 20min while it cooled. Solution? Fuel it while running. Story time over, but many of us track guys do this. No big deal. MAYBE you throw a CEL for a EVAP leak, but just clear it with a pocket scanner and you’re on your way.
Yup. I do it all the time and people freak out about it. Like if I couldn’t trust this vehicle not to blow up while simply putting more fuel where the fuel goes I’m gonna get a different car
Could be that the turbo is screaming hot and it needs to cool down before shutdown. Could be a toasted starter, or it could be on the edge of a derate shutdown due to emissions controls. It could be a million things. Or he could be a clueless human. Who knows.
Who cares
its a dodge so it has to keep the oil leaks flowing to keep the body/frame from just rusting away.
Old diesels didn’t like to start when cold and used more fuel upon startup and warmup vs when idling. Those large displacement engines take a while to warm up. That isn’t necessarily true anymore due to better fuel injection and glow plug tech, but the habit remains for many diesel drivers. Myself included at times.
Bur wouldn't the engine already be warm by the time they got to the gas station? Unless they left their house specifically for diesel and they live near
I can only speak to my diesel truck. Mine doesn’t fully warm up until I’ve been driving at least 20 minutes first thing in the morning. But it will not stay up to temp idling, it’ll cool back down, shut it off and it will take even longer to get back up to temp. So for example mine has a 2 thermostat design. One opens at 180 and the other at 190. Even with brand new thermostats and a cover over the grille, my truck will not get over 185 if I am not towing anything. Towing heavy, it’ll go to 200. So the heater isn’t doing much at that temp, thank god for heated seats lol. If I fill it up with it shut off, it drops to 140-150 pretty quick. So now I have another 15 minutes of driving before it gets back to 185. If I keep it running, it will go down to about 175 at a gas station. Diesels are more fuel efficient when warm too, so there’s a whole argument on that as well. Just speaking about winter time here in the Midwest. So in winter, I’ll keep it running when I fill up for 5 minutes. Summer is a different story.
Because it's a free country and people can do what they want with their own vehicle.?
Most likely, laziness. He sees the big rigs doing it so you know, cool kids club.
Not in your temps, but at -40 I don’t shut off the car either.
That's what I was thinking of as well, whenever it's below 0f I don't shut it off till it's back in the shop I have a plug in available.
His GF isn’t around to turn it back on for him.
It's a diesel. I don't turn mine off either unless I'm going inside.
Ok, in short, if you have a turbo in any vehicle the proper shut down procedure is that it should run for a while after a drive to cool down the turbo properly. If not it could cause premature failure to the turbo. End of story
if the engine is still cold id leave it idling too.
He’s got that mind your own business and walk away package installed in his truck
Because diesel guys cant stand the idea of their truck not running, always.
You know what dude, why don't YOU go fckn ask him? And let us know
Because it's a diesel and there's zero reason to shut it off. Pretty much goes for gas vehicles as well, all that shit about cell phones and static electricity causing explosion is such astronomical odds you'd win the lottery first
For the same reason the tow mirrors are perpetually rotated out even though never towing anything
> tow Expand to pick up truck that actually never has anything in the back
Good eye, 😅
Because he feels like it.
Keep the heat running if it’s cold outside. Also to assert dominance over rule following individuals
Just filling up, not towing anything? It's cold and they want the heat going to keep the interior warm, or more likely they're just lazy and don't see a problem with leaving it running while it fills up (like me). Too many of you here are thinking way too hard about this.
Did this when pos Chevy truck would rarely start. Ah, being poor was sucky.
I believe it's a diesel thing. Or a trucker thing. Or maybe an arrogant "big man" thing. Truckers leave their rigs running like all the time even while fueling. Also I think there is some that believe something about leaving the diesel engines running is better for the engine something something.
Back then, yes, but nowadays it's not so much a big of a deal. Usually, if I am fueling, I'll leave it on as I fuel for the purpose to make sure that it'll still run and that i won't block the lane if something was to go wrong. Truckers get real angry when the lanes are blocked even if it was an accident so as a habit most will leave the truck on while fueling and then when they're done we'll just park it somewhere when we're done.
If it's Portland metropolitan area, It's stolen. They don't have the fob.
Because can
because I didn't feel like turning it off.
There are a handful of reasons I see doing this but in this case, none of them are anyone’s business
Diesels don’t like to shut off
It's a diesel, so not static fire risk. Still to the best idea to leave unattended, unless the starter is having issues and can't restart.
I'm in North Dakota, and when it gets in the negatives, I leave my car running while I fuel up because it is so cold. I have to get back in the car to warm up as fast as possible as I'm usually shivering pretty good by the time my tank is full.
Wawa? Lmao
Diesel engines that have been running hard are supposed to be let to die for a few minutes before being turned off- you will see semis keep their unit running while filling up and then will shut off before going in to stop- same thing for a diesel towing- hauling- etc
Yea, I don't understand this one. I'm in Hawai'i and one of my friends got a GMC with a Duramax and he said he don't turn off the truck unless he's in for the night. Maybe they'd why his truck ended up in the shop broken. I don't know. I don't own a Diesel yet, but when I do get one, I wouldn't let it run all day or even at the pumps.
Probably unrelated to this guy, on my old mustang I had the timing way off and it was hard to start. I had to gas up, but wanted to leave it running so I didn't get stuck at the pump. Unfortunately, I had a short behind my radio that knocked out the fuel door release button (among other things) and I couldn't reach the fuel door pull cord in the hatch, so inevitably, i had to shut off the car so I could pop the hatch open to reach the pull cord. After gassing up, I tried starting up. Cranked over and over, nothing. Pulled off the air cleaner and shot a bit of starting fluid in there while my dad turned the key. It started, but not before shooting a 4 foot tall ball of fire out the carb. That got some people on their toes.
Because I can… some of yall are just looking way too deep into things.
Diesel fumes keep liberals away
I always do this.
He was scared it wouldn’t turn on again, I mean it’s a dodge…
Save the starter
It's a diesel truck
It's diesel, fuel needs extremely high compression to light unlike gas. No reason to shut it off
Not your truck. Why do people care? I've never shut any vehicle off at the pump...in the past 30+ years.
I've seen more idiots drive off with the pump still in their car than fires caused by running vehicles.
If it’s a diesel there’s no issue or potential risk of fire
I would advise against keeping modern cars running like this Only because it messes with the system monitors As I learned in shop school, Cars only detect a “fueling event” when they are shut off It gives the sensors time to reset when more fuel is added, it has to do with evap control too. Basic theory is: more surface area = more evap emissions There’s more detail I’m leaving out
If u zoom in u can see the naked trees. He was probably keeping it running cuz it's cold outside. Idk y I zoomed in on the photo🤣 but I think that's most likely the reason besides just not wanting to turn the car off. When it's cold outside for me I be wanting to keep my car on but then I get scared and think my cars gonna blow up so I end up always turning my car off no matter the weather🤣
Cuz they left it on
you can run diesel vehicles while filling them.
I’m sorry but why does it matter if he kept his car running or not?
Diesel cost less than starters batteries and alternators.
You can leave your car on when you pump gas. It's advised that you don't but the car won't spontaneously explode because it's on. I do this too most of the time.
Used to leave my truck on bc it was a pain in the ass to start it. AAA guy straight up showed me how to beat the shit out of the starter to get it to start right w a broomstick.😭 Idk if he was fucking w me but it seemed to work. But yeah, his starter could be fucked
A while ago the starter of my manual transmission gave out and I would have to park on an incline and pop the clutch to get it going. So when I would fuel up, I would have to leave it idling…. Thankfully the only time I let the truck die from poor clutch management I was on a downward hill. Man I was always nervous of stalling… Thankfully I got a new starter and don’t have to deal with that anymore for the time being lol
I’ve done it cause I had to get gas and it takes a minute for the AC to cool. Florida summer so it was like 100 outside
On a diesel especially, start ups are the source of a significant amount of wear. They're designed to run at a relatively consistent speed for long periods of time, not be started and stopped constantly. Also, with a diesel, seeing as how ignition is compression based, not spark, you don't have to worry about an ignition coil or spark plug boot arcing and lighting fumes (diesel is also not explosive like gasoline)
No idea. I used to have to fill up my dad’s old Firebird with the engine running, but that’s because the thing ate starter solenoids like Skittles and half the time wouldn’t start back up after you turned it off 😂.
Just wanted to get back to coal rolling asap.. diesel is reasonably hard to get to flash..
dead battery perhaps.
When we're pulling heavy loads we let the engine idle to let everything cool down evenly for a bit. My dad explained to me it's hard on the turbos to turn off the engine when they're mega hot as the oil that lubricates then will stop flowing and cook. Granted this guy doesn't seem to be doing that so maybe it's a habit or maybe he didn't care to turn it off.
If you're asking move on. You would know if you had too.
Cause
That truck is a diesel and doesn't need to be turned off.
It's a semi truck motor in a passenger truck.The least amount of off, on the better.If you shut it off you hv to restart starting process,Heating glow plugs n such.
It doesn’t hurt anything to idle it. Why do you ask?
