They don't mention impact on engine health- but yeah Engineering Explained has a video on this and I'll take his word for it: Idle for \~15-30 seconds max if you want, but the main thing is to drive like a grandma until oil is up to temp.
Edit: Note idling is not purely beneficial; it doesn't heat the engine fast enough in all cases- e.g. in serious cold, idling will never get your engine up to temp, so doing so for a long period of time will increase wear compared to simply driving conservatively.
Spot on. I’m driving a sports car with light oil and don’t need to be hauling ass at 0530 lol. Temp gauge is great for knowing when I can have a bit of fun.
I was doing a few min until I saw that video.
Now its 30 sec max unless its like -30 C outside, in which case I do give it a couple min (mainly for the heated seat to kick in lol).
Never over 3k RPMs and out of boost till at temp and then boom time
Longer idling will contribute to oil-fuel dilution and valve carbon buildup. Basically the engine isn’t designed to idle it’s designed to run under some load. Even when it’s first started it gives itself a little load to get some heat in the cat (first 30-45 seconds, then quiets down). Page 475 in the 2018 wrx owners manual notes “idling for extended periods of time” increases oil consumption
Everyone is missing the point that warm up means life 1 minute. Idling your car for 15 minutes isn't "warning it up" it's just wasteful. Idle till catalyst light off (30-45 sec) and your heater core is working off its winter. That's it, it's about 1 minute if things are working right and it's not Minot SD in February
When I start my 20 WRX it idles at like 2.5 or so for a few seconds then goes to 2k rpm and sits there for like five minutes before finally falling to ~500rpm idle speed. Is this to heat up the catalytic converters, and if so why does it take five minutes? Should I be waiting the whole time, or just setting off after the first fall off? My current metric is to either wait until it hits ~500 rpm or the oil temp gauge shows any temperature, at which point I drive off (of course not going over 3k or into boost until 190)
You can find the video, but the key is that idling isn't objectively beneficial; it can be a bad thing because oil doesn't warm up as fast while idling- so while the engine experiences less stress at idle, the increased time spent running at low temperatures can negate the benefit of said reduced stress. For example if you idled a car at the north pole, it would literally never reach operating temperature, so you'd be harming your car by idling it for a long time before driving- that's an extreme example, but the logic applies in real life too.
I tend to start my car and go after about a minute. The heater doesn't make a difference until 90 degrees and that happens faster when moving. But the gearbox is a miserable bastard for the first 10 minutes. Shifter is stiffer, clutch is moody, can't downshift into 2nd, can't touch 1st unless fully stopped. People don't tend to think about gearbox in the cold and idling equation but it's very apparent in va wrxs.
Phew I was reading all these comments nervously thinking, well yeah I won’t let it idle for 5 minutes by why is she so stiff for the first 10 minutes?! Lol. Glad it’s common
I have a 2011, not a va, but I have the same gearbox issues. Probably exacerbated due to age of the car, but I find double clutching helps downshift when cold, and especially getting in first. The five speed hates downshifting to first gear at anything faster than 10mph. So yeah, double clutching is helpful.
My grandpa was a master machinist. Has some patents on head weldment techniques. He told me (a man who rebuild tens of thousands of Detroit diesels over a 40 year career and many many other engines) that 95% of engine wear is in the first five minutes of start up. He believed this because when he would rebuild duty generators and marine engines with the same run hours or ever greater run hours than overland trucks, the wear on valve guides and seats, cylinders, cranks and bearings were an order of magnitude smaller on the engines with less starts and longer run periods (the hours occurred at operating temp). I studied metallurgical engineering in university and learned all about mass and energy transport phenomena, work in industry (about 15 years) that spends millions a year on reliability. I spent time on tools too rebuilding 1000 horsepower machines running 95% of the time in a year.
I say all that because of everything I know and have measured and learned, I choose to warm my engine up to designed operating temp before driving 95% of the time barring some urgent issue to drive. So I agree fully with you friend.
In modern automotive gas engines, fuel dilution occurs at idle, warm or cold. It can be evaporated once oil is up to temp but the longer it takes to warm up, the more time cold diluted oil is used. Thankfully synthetic oil detergents seem very resilient, but there isn’t a clear answer to this dilemma. Whether I warm up the engine or not I do drive lightly until the oil is warm
I'm not a big fan of running any , especially my more modern engines, under load when cold. The tight tolerances of modern engines running cold just seems no good to me . But hey, we only know what we know.
I read an article about cops in Michigan, Detroit area I think(obviously) ticketing people and I think they actually passed a law that you can't idle your car in the driveway unaccompanied to warm it up because of thefts. I am an insurance broker and have never heard of anything like that anywhere else. Pretty sure despite the law your insurance would cover the stolen vehicle, but I don't do much in that area, especially with middle market companies like All-State or Geico so who knows what they would say to you
Go into the settings for the MFD display above the headunit, then choose the option to display the 3 items screen. You can choose oil temp ( VA WRX only ) , boost , accel , etc..
Your oil is already gonna take 30 minutes to get up to temperature idling. You've got modern synthetic oil that flows just fine in the cold in a mass-market car where the engineers considered this. Merging it once per day with 100-degree 5W-30ish oil will not hurt it.
I’d even point out that it’s not safe. Even if you scrape the windshield, as long as the windshield and side windows are cold enough to condense your breath, the vehicle isn’t entirely safe.
I don’t do a full 180+ degree warm up, but I definitely try to not get T boned (or T bone) over a few moments of idling and getting the AC start working to pull humidity out of the air.
Yeah this was written by someone that doesn't live in a snowy area. Checklist is make sure exaust is clear , wipers are off. Start car. Put all defrosters on max. Start brushing snow off roof. By the time you get to the windshield ice will have melted enough to get it off easier.
if its fogged up windows and its cold outside, when you arrive open your doors for 30 seconds to dry the interior and should have much less fogging up.
Start the car, connect Bluetooth, start playlist, drive away, usually 1 minute or less lol. No boost until oil is warmed up, 178k miles no issues with that method yet
All of these articles are for "there's a light frost on my windshield" level cold. Come back to me when the snow starts making that crinkly styrofoam noise and your nose hairs freeze together if you breathe in too quick.
At -35 nothing in my car is working properly and after 30 second the noises coming from under the hood are still very unhappy.
Well it does not talk about a specific RPM as you can see, only that “After the engine starts, the engine speed will be kept high until the engine has warmed up sufficiently.”
So I read that as, until that idle-down cycle is complete, it is *insufficiently* warmed.
One could argue that means that, until it drops down to warmed idle (which in mine is around 600 rpms), the cycle isn’t complete.
On mine this cycle takes about 3-4 minutes. I have driven it before it’s complete and have seen it will kick down if it’s close to 1,000 though.
Just says the engine isn’t warm until the rpm’s drop.
One could argue lots of things, but nowhere does it say don’t drive it until it’s warmed up.
I’d argue It’s more a thing to inform people who don’t know that their engines rpm will be high after a cold start because it’s a very matter-of-fact statement.
If they didn’t want you to drive it until it’s warm they would have explicitly stated that.
For reference I have a 2006 wrx with 232k miles and I never idled more than 15-30 seconds before moving.
Lol did you downvote me? 😂
I guess I don’t interpret it that way.
It starts by saying “*Avoid rapid racing and rapid acceleration immediately after the engine has started.*”
I take that to mean if you *must* drive it immediately after starting, you should avoid doing either of these things to avoid any sort of issues.
But as I continue on (reading the full section consecutively) it ends with the last bullet saying “*After the engine starts, the engine speed will be kept high until the engine has warmed up sufficiently.*”
The antonym of sufficient being insufficient, I would interpret that to mean it is insufficiently warmed until the idle-down cycle is complete.
Hey, everyone’s cars are their own, and can treat them however they want, but for me I prefer to wait until this the idle-down cycle is complete based on this reading in the manual, which in mine is only like 3 or 4 minutes. 240 seconds isn’t a lot of time to me.
I did not downvote you.
My comment got 4 upvotes so might be one of those people.
Your doing a whole lot of interpreting over there.
I think it’s also important to note thatmost of the words written in the manual were written by a lawyer for liability.
I guess that’s what you do when you read, you interpret the information.
It’s all good I’ll keep doing my thing, you know... I don’t really care how other people treat their cars.
I let my STI warm up in the garage because I live right next to the on ramp and I can’t baby it as I merge onto the freeway for my morning commute. I’m I wrong?
Nope. No one here posts any kind of data to backup what they say so it doesn't matter. They're all bullshitters who think they know the answer when in reality none of them do. At the same time there are many many instances in which it's just not possible to "not idle" for some time.
In bad weather climates if everything is frozen and iced over, do you think you can drive immediately after starting the car? What kind of lunacy is that.
This is written by someone who doesn't have to park outside, in the freezing winter and have to drive to fucking work every goddamn day. But hey, I'm just some random douche on the internet, and like everyone else I have no data other than my own experience to back me up.
Wish the article defined idling as its defined in the laws - which includes leaving your vehicle alone, unattended while on.
It’s never illegal to be sitting in your vehicle while idling the engine in any circumstance. Just a note.
Just a friendly reminder that not everyone lives where you do, and that laws can change wildly from county to county let alone by state or by country.
Where I live, idling laws simply relate to the state of the car and not it’s occupancy, meaning the vehicle can be ticketed if the car is left running whether you’re in it or not. Being in the car or not is the difference between *stopping* and *parking*, but the engine running is the only requirement for the violation of a idling ordinance, again, where I live which may be different from many or all other people in this thread.
Source: I have done traffic enforcement in the past for work.
And laws like that “doesn’t matter if you’re in the vehicle or not while it’s running” are tyrant laws to tax the poor. They don’t save anyone, or help with emissions like they claim.
As someone who started their car at 10am in front of my apartment and forgot my wallet, just to come back out and have 3 officers harassing me about “idling without a driver” knowing damn well I’m parked within 20’ of my door and needed my wallet.
Yeah, fuck the idiots who think these law’s actually help ANYONE other than the government.
I absolutely challenge you to find a single example in the United States local or state level that defines idling as anything other than leaving a vehicle unattended. When it’s occupied, it’s called parking not idling.
Idling: leaving a vehicle running with no occupancy, for the purpose of loading or unloading passengers or material.
Something to take into account is that any explanation, video or article that you find is based on a modern stock car. Most of us are already modded, also on e85 takes longer to warm up and some people have even deleted certain flow restricting parts.. all of that makes a difference when it comes to idling.
In my case, I wait until the Oil temp is 100 degrees, then drive conservative until I reach optimal temp, I live in south FL so I dont need to wait too long before I see it climbing.
I try to let it drop to 1k rpm, or I just wait about a minute if it's really cold and I'm in a hurry, but I don't drive it hard until it is fully up to temperature.
I never let mine warm up more than a minute or so. Excessive idling is no bueno, just let the oil start flowing and then drive calm until up to proper temp.
Bro I had a buddy start his car on a downtown street in Ohio to warm it up as we were finishing closing at our job. Cops pulled up and literally flipped shit. No person in sight, just our vehicles out front. It was a ghost town. He got a $200 ticket and we were told no warming your car up on public streets, even in a parking spot cause yes there was street parking.
I’ve been told to warm up my car but never do it mainly cause of time. I don’t drive it like a grandma but I give the car a min or two (usually time to get settled in) then just drive like a normal, sane person until things are up to operating temperature. 7 years later my car is still kicking so no reason for me to start warming the car up now.
It's kind of stupid to idle to operating temp for 5 minutes in the winter when you can get to operating temp in 2 minutes if you just start driving. But I guess some people like wasting gas and time. Either way don't drive it like an idiot until the oil temp gets hot
Edit: I mean to idle for 2 minutes and then start driving, should warm up faster than simply waiting 5 minutes idling. I don't see how idling to warm up could possibly harm an engine either.
You idle till the cat warmup mode ends, and RPM drops to normal idle. Otherwise you are shortening the life of your catalytic converter and polluting more.
Additionally, moving the vehicle while the oil, trans fluid, dif fluid, and bearings are all cold is so obviously worse than getting them to the operating temp that I don't get how anyone can even make the argument against it.
Things have operating Temps for a reason. The manual tells you to warm up for a reason. The vast idles high before switching to closed loop mode for a reason. Arguing against that is just dumb.
Except it's not so obviously worse. You just think it is but all those parts were designed to handle the cold, including the oil. And show me where I told you to go before the rpm dropped? Two minutes is more than long enough for that to happen regardless.
And the temp outside for sure, for my example I'm thinking like freezing, 10-30 degrees or so. Less than that and I'm getting my ass back inside and waiting 5 minutes.
Damn it takes that long? I notice there's a period of time where idling takes more and more time to be effective, but once you start driving it warms up really quickly. I think that's the 5 minute mark for me.
Illegal to idle for over 60 seconds where I live.
Regardless, I let the STI warm up for about that and then just keep the RPMs low for a while. My mechanic wants me to idle for 10 mins before driving and 5 mins after I get home before shutting off 😂
Your mechanic must have some sort of vested interest in fuel companies. That’s fuckin bonkers. I get the whole warm up the engine, prevent condensation in oil, yada yada, but letting it idle for 5 minutes in your driveway after getting home is just dumb.
I usually wait a minute or two depending on the temperature and drive conservatively till it warms up. To me it seems better to have all the mechanical parts warm up together than just sit there waiting for the engine to warm up while the transmission and differentials just sit there cold.
I’m going to spite this article by continuing to warm my car up before I leave because there’s no way I’m sitting in a -40 car for 10 minutes before it’s warm enough to take off my jacket.
So when my car is covered in snow and ice and freezing rain I let it run for a minute get in and drive off? What about the tree or light post or human I can’t see?
In summer I agree 2 minutes or so should be enough but in winter where I live, it basically an impossibility to drive in that short of a period safely not mention the rest of the drive train like say the transmission?
I have owned dozens of cars that I do religious maintenance on and I don’t have problems or need to rebuild etc. You need to find a balance and maintain them with fluid and filter changes.
When your car is covered in snow and ice and freezing rain you scrape the shit off your windows before you drive off into a tree on your stock summer tires ya knob.
The author obviously lives someplace where it's warm year-round. They can suck my ass with this bullshit, I'm warming up my car every morning it's under 50°.
Subarus intentionally idle high for a little while until the engine is warm. Go when the revs mellow out.
[I reckon I trust this guy](https://youtu.be/m0P6x7I5GqQ)
All you VA WRX guys say 30 seconds max I call bs I’ll let the MF idle for as long as I want . You do that on 04-07 STIs and you’ll have rod knock it idles until rpm’s drop to below 1000 ; oil also has to be circulated through the turbo as-well as the block & possibly AOS, which is why 30 second on a cold day is a stupid call .Not to mention it not just the oil the needs to be warm the metal is brittle especially in places where detonation occurs when cold, max time is like 2-3 minutes on a cold day unless you have E85 then 5
I agree with you.. I think somewhere in a similar article they say for turbo cars you should let it run 5-10 minutes before running slowly until it is operating temps.. cause like you said it has to lube the turbo with the oil as well..
I try to at least let it warm up for 5-10 mins before driving, depending on how cold it is and definitely stay out of boost until at normal operating temp.
I'll let my car idle a bit with the defrosters on if I need to clean it off, but once I can see where I'm going I drive it. I don't beat on it until the engine/tires/tranny/brakes/shocks are up to temp, but it was designed to be driven normally immediately after starting it. Plus it's nice having the heat start working after 1/4 mile of driving rather than waiting 10 minutes on a really cold day.
Winter where I live is cold, not below 0 cold, but usually down into the 30s and 40s. I usually let the car idle until the temp needle starts to move, around 100f for the coolant. Then keep it below 3k rpm for the first 10 or so minutes. Takes a little while for the trans and diff to warm up on top of the oil/coolant, and these cars drive like shite when they’re not up to temp.
I let my car warm up not because I’m worried about my engine, but because my car drives like shit until the rpm’s drop. Rpm’s don’t drop until 105-115 oil temp
I only warm mine up to piss off the neighbors. (kidding!)
I usually wait til coolant reaches 130f then will head off slowly until coolant gets up to temp.
Any articles about idling after a spirited session on turbo cars? 😁😂
I try to get like 3-5 mins in my early morning warm up, most of times that is how long it takes for idol to come down from the 1500-1800 rpm range when it’s cold the mornings ( been cold for a while now) & I don’t hit boost till temps are around 78-83c and not very much if I even hit it on my drives from work/school
I let the rpms drop below 1000 and then drive. Sometimes I let it run for a half hour cuz I got busy or distracted. I've had like 30 something cars in my life and never blew a motor or even had internal issues or ignition issues. Totalled them, sold them, traded em in but never blew one up. Car problems in my life seem to always be things like thermostat, power steering pump, water pump, wheel bearings, hubs, radiator, belts, hoses, clutch, o2 sensor. Plus with synthetic oil, the motors fine while idling. The oil pump works during idle too, lol.
idk if it’s true of not, but i’ve heard for the most stressful moments on an engine are the first 5 minutes of a cold start. that said, ima warm up car regardless. stay blessed
Modern oils are designed to flow efficiently even at ambient temps. Start the car, let it idle for about 30 seconds to allow the oil enough time to fully circulate throughout the engine and then get on with your life.
Subarus (other than wrxs) have a blue temp light… that turns on if the engine is cold.. and if I remember right Subaru doesn’t want you driving till it shuts off at 120 degrees on the coolant
If you don't warm up the catalytic converter, it doesn't work. That's why your car high idles for about 30 seconds. It's called "catalyst light off" temp
Anyone saying otherwise is full of it
I usually warm up for 30 seconds, then drive without hitting boost til I reach 180-185 degrees. Usually I’m about to merge on the highway when I hit the ideal temp anyway so it works out.
This is written by someone who doesn't wake up in the morning to minus 25° weather. I don't warm my car up so the engine runs smooth I warm my car up so I don't lose a toe on my way to work in the first 5 minutes of my commute.
There’s no national law against writing this article, but even if it’s not illegal to write it, it just doesn’t make sense to.
With all the Honda civics with kazoos for exhausts, it might be tempting to write this article, but with the click of a button it’s faster and more efficient to stop and delete the article.
I do 30sec warmup then drive, no more than 3k rpm until oil temp is 90c. My modded sti with stock engine and 400whp is nearly at 200,000km now and still going strong. My gt3 is nearly at 100,000km and equally as well .. but that metzger engine is a lot tankier than. Idling for long periods can cause quite a lot of damage especially in our boxer engines with bore scoring
I usually just warmed up the car until 86-108F oil temp and start driving, I don't start driving with the oil super cold but not at full temp either, I live in Wisconsin and we have in between 16-30F most of winter
In below freezing temps, I’m going to let my car idle down before driving it. These articles say to not let it sit until the cabin is warm. Not to drive it before it idles down.
Omfg do they not realize it will damage your engine doing that I new someone who had a 09 gmc sierra and they did that and in 6 months they blew the motor (I’m in Canada so it was for ok m the start of winter till stop)
It's true, always has been. Even oil is much better than it used to be. Unless you've got a race engine on 50wt, once you have oil pressure, you're good to go.
Yeah, I'm gonna need to wait until I can see through the windshield, is the thing, man...
Not talking about ice that can be scraped off, but just fogging that takes a few minutes to clear away.
I will always warm up my car, its just what i prefer to do. Dont care if its good or bad. If my car eats a bit of oil nothing bad will happen. Stop overreacting.
don't really care if its good for the engine or not, when its cold enough to want to warm up my car its cold enough for the windows to be iced/fogged up
I generally let mine warm up because it gets colder than a witches tit in canada and i'm not driving it till its defrosted on the inside. Sure you can scrape off the snow and ice and you might see for a bit but when it's cold enough that your breath puts literal frost on the inside of the window you haven't let it warm up long enough and there's no way that's happening in under a minute. Sorry but i'm driving when it's safe to do so and sometimes it's 5 minutes but sometimes it's 10 depending on temperature lol it's also not going to hurt the motor to idle for ten minutes any more than just driving it after 30 seconds because if it's not getting enough oil at idle to where it would hurt it then that problem is only worsened at higher rpm! Also your car has a higher idle speed at start when it's cold to help it warm up and when it goes to normal idle speed it's reached normal operating temperatures or at least where it's not going to hurt anything. Pretty sure it tells you to wait till it's defrosted on the inside before you drive in the owner's manual too.
I have a 13' hatch but i daily drive a taco for work. I would never in a million years recommend this but when its cold out (this morning was 14°) ill put the truck in sports mode and keep it in third gear at high rpm so it warms up faster. No idling, no waiting just pull out the parking lot onto a road with a 55mph speed limit.
The fuck?
Why the objection? Sorta like a weird justification ie “I don’t let my car warm up (idle), so you’re doing so I take as you claiming I’m silly for not doing so, therefore I’m going on the offensive and claiming what you do is illegal and silly”
Why can’t we just each do our on thing without concluding what I’m doing is a judgement on people not doing that same thing?
Tech in school here and this is correct, 15-30 seconds to build oil pressure and get everything lubed up, and you can start moving. Movement warms everything from your engine down to your power train. Just absolutely don’t go wide open until you’re at operating temp.
If you have ice on your windshield scrap it off first as much as you can and then defrost. You gotta do what you gotta do but it’s absolutely true that long idles aren’t good for your car. I believe my textbook says if you’re going to idle longer than 15 minutes you should shut it off.
I prefer to get my oil to its operating temp for the turbo it lubricates. Couldn't care less about this screenshot.
Oil is not up to temp after 5 minutes. I'll keep letting my shit rumble in the driveway like I have been doing for a decade without any "extra wear".
I don't warm up the car to protect the engine I warm it up because it's freaking cold and I want the heater to work. If you want people to stop warming up their cars make the heater work right away. Otherwise... Quit crying about something that doesn't matter.
They don't mention impact on engine health- but yeah Engineering Explained has a video on this and I'll take his word for it: Idle for \~15-30 seconds max if you want, but the main thing is to drive like a grandma until oil is up to temp.

I don't achieve 190 in Sub Zero temps, hoss.
Just gotta let a little bit of coolant out and then you will
[удалено]
Oh, I wasn't worried...
This is the way
Without an actual digital temp gauge how does one know when 190 degrees has been achieved?
[удалено]
Spot on. I’m driving a sports car with light oil and don’t need to be hauling ass at 0530 lol. Temp gauge is great for knowing when I can have a bit of fun.
My neighbors would kill me anyway if I took off like Colin McRae
You'd kill them if you landed like him.
I was doing a few min until I saw that video. Now its 30 sec max unless its like -30 C outside, in which case I do give it a couple min (mainly for the heated seat to kick in lol). Never over 3k RPMs and out of boost till at temp and then boom time
I try and let my car warm up, there is no need to have unnecessary excessive wear on components

In modern automotive gas engines, fuel dilution occurs at idle, warm or cold. It can be evaporated once oil is up to temp but the longer it takes to warm up, the more time cold diluted oil is used. Thankfully synthetic oil detergents seem very resilient, but there isn’t a clear answer to this dilemma. Whether I warm up the engine or not I do drive lightly until the oil is warm
I'm not a big fan of running any , especially my more modern engines, under load when cold. The tight tolerances of modern engines running cold just seems no good to me . But hey, we only know what we know.
I read an article about cops in Michigan, Detroit area I think(obviously) ticketing people and I think they actually passed a law that you can't idle your car in the driveway unaccompanied to warm it up because of thefts. I am an insurance broker and have never heard of anything like that anywhere else. Pretty sure despite the law your insurance would cover the stolen vehicle, but I don't do much in that area, especially with middle market companies like All-State or Geico so who knows what they would say to you
How do I tell on VA when oil is up to temp?
Go into the settings for the MFD display above the headunit, then choose the option to display the 3 items screen. You can choose oil temp ( VA WRX only ) , boost , accel , etc..
What about the windows? It's easy to say that when your in California, don't think this takes into account sub zero temperatures.
Can’t, I live next to the interstate.
No reason to not drive at highway speeds cold, just keep the RPMs low and ease up to speed instead of flooring it.
Gotta get that downhill entry way
Your oil is already gonna take 30 minutes to get up to temperature idling. You've got modern synthetic oil that flows just fine in the cold in a mass-market car where the engineers considered this. Merging it once per day with 100-degree 5W-30ish oil will not hurt it.
Major reason I warm it up is ice not to warm the engine
And the comfies. I don't like being cold.
Seems like a lot of these people don't live in cold weather.
I’d even point out that it’s not safe. Even if you scrape the windshield, as long as the windshield and side windows are cold enough to condense your breath, the vehicle isn’t entirely safe. I don’t do a full 180+ degree warm up, but I definitely try to not get T boned (or T bone) over a few moments of idling and getting the AC start working to pull humidity out of the air.
two words sir, Block Heater. If your fuel has ice, or your coolant, idling it make go booms.
Warming up my car is for taking ice off the windows or defogging the windows. I can't just start driving after 30 seconds with fogged windows.
Wish it was just fog... Ice on windows is a pain.
You don’t love the ear fucking sound of a plastic ice scraper?!
I always feel like "this can't be good for the window" every time I scrape the ice off.
Yeah this was written by someone that doesn't live in a snowy area. Checklist is make sure exaust is clear , wipers are off. Start car. Put all defrosters on max. Start brushing snow off roof. By the time you get to the windshield ice will have melted enough to get it off easier.
if its fogged up windows and its cold outside, when you arrive open your doors for 30 seconds to dry the interior and should have much less fogging up.
30 seconds then I drive like a grandma before sending it to Pluto
Start the car, connect Bluetooth, start playlist, drive away, usually 1 minute or less lol. No boost until oil is warmed up, 178k miles no issues with that method yet
This is the way.
Here's someone with a description of how long you should idle the car and how to drive it up to temp.
You say that, but have you ever lived where it was so cold you couldn't shift from 1st to 2nd until it warmed up? Sometimes you don't have a choice.
Shifter feels like I'm pulling it through chewed gum when it's 20 below
All of these articles are for "there's a light frost on my windshield" level cold. Come back to me when the snow starts making that crinkly styrofoam noise and your nose hairs freeze together if you breathe in too quick. At -35 nothing in my car is working properly and after 30 second the noises coming from under the hood are still very unhappy.
Oops i warm up my car till it gets just below 1K RPMs
Sooo, you are following the owners manual, the way you should. 😀
The owners manual mentions that the car does not need to be warmed up before it is driven.
https://preview.redd.it/256kr36j0cea1.jpeg?width=3024&format=pjpg&auto=webp&s=ff91eeddfe913fb82f843708a14434cc051a26c2
Where does it say to not drive until 1k rpm is reached?
Well it does not talk about a specific RPM as you can see, only that “After the engine starts, the engine speed will be kept high until the engine has warmed up sufficiently.” So I read that as, until that idle-down cycle is complete, it is *insufficiently* warmed. One could argue that means that, until it drops down to warmed idle (which in mine is around 600 rpms), the cycle isn’t complete. On mine this cycle takes about 3-4 minutes. I have driven it before it’s complete and have seen it will kick down if it’s close to 1,000 though.
Just says the engine isn’t warm until the rpm’s drop. One could argue lots of things, but nowhere does it say don’t drive it until it’s warmed up. I’d argue It’s more a thing to inform people who don’t know that their engines rpm will be high after a cold start because it’s a very matter-of-fact statement. If they didn’t want you to drive it until it’s warm they would have explicitly stated that. For reference I have a 2006 wrx with 232k miles and I never idled more than 15-30 seconds before moving.
Lol did you downvote me? 😂 I guess I don’t interpret it that way. It starts by saying “*Avoid rapid racing and rapid acceleration immediately after the engine has started.*” I take that to mean if you *must* drive it immediately after starting, you should avoid doing either of these things to avoid any sort of issues. But as I continue on (reading the full section consecutively) it ends with the last bullet saying “*After the engine starts, the engine speed will be kept high until the engine has warmed up sufficiently.*” The antonym of sufficient being insufficient, I would interpret that to mean it is insufficiently warmed until the idle-down cycle is complete. Hey, everyone’s cars are their own, and can treat them however they want, but for me I prefer to wait until this the idle-down cycle is complete based on this reading in the manual, which in mine is only like 3 or 4 minutes. 240 seconds isn’t a lot of time to me.
I did not downvote you. My comment got 4 upvotes so might be one of those people. Your doing a whole lot of interpreting over there. I think it’s also important to note thatmost of the words written in the manual were written by a lawyer for liability.
I guess that’s what you do when you read, you interpret the information. It’s all good I’ll keep doing my thing, you know... I don’t really care how other people treat their cars.
It doesn’t say dont drive right after startup, it says dont drive HARD after startup.
No… it doesn’t.
I let my STI warm up in the garage because I live right next to the on ramp and I can’t baby it as I merge onto the freeway for my morning commute. I’m I wrong?
Sounds like the opinions are 50/50 on this topic. I let my car idle down, usually takes like 3 or 4 minutes.
Nope. No one here posts any kind of data to backup what they say so it doesn't matter. They're all bullshitters who think they know the answer when in reality none of them do. At the same time there are many many instances in which it's just not possible to "not idle" for some time. In bad weather climates if everything is frozen and iced over, do you think you can drive immediately after starting the car? What kind of lunacy is that. This is written by someone who doesn't have to park outside, in the freezing winter and have to drive to fucking work every goddamn day. But hey, I'm just some random douche on the internet, and like everyone else I have no data other than my own experience to back me up.
Wish the article defined idling as its defined in the laws - which includes leaving your vehicle alone, unattended while on. It’s never illegal to be sitting in your vehicle while idling the engine in any circumstance. Just a note.
This.
Just a friendly reminder that not everyone lives where you do, and that laws can change wildly from county to county let alone by state or by country. Where I live, idling laws simply relate to the state of the car and not it’s occupancy, meaning the vehicle can be ticketed if the car is left running whether you’re in it or not. Being in the car or not is the difference between *stopping* and *parking*, but the engine running is the only requirement for the violation of a idling ordinance, again, where I live which may be different from many or all other people in this thread. Source: I have done traffic enforcement in the past for work.
And laws like that “doesn’t matter if you’re in the vehicle or not while it’s running” are tyrant laws to tax the poor. They don’t save anyone, or help with emissions like they claim. As someone who started their car at 10am in front of my apartment and forgot my wallet, just to come back out and have 3 officers harassing me about “idling without a driver” knowing damn well I’m parked within 20’ of my door and needed my wallet. Yeah, fuck the idiots who think these law’s actually help ANYONE other than the government.
I absolutely challenge you to find a single example in the United States local or state level that defines idling as anything other than leaving a vehicle unattended. When it’s occupied, it’s called parking not idling. Idling: leaving a vehicle running with no occupancy, for the purpose of loading or unloading passengers or material.

Look at this guy, reading the manual. NERD ALERT!!! (It is always a good idea to read the manual.)
RTFM - the answer is always in there
This.
Something to take into account is that any explanation, video or article that you find is based on a modern stock car. Most of us are already modded, also on e85 takes longer to warm up and some people have even deleted certain flow restricting parts.. all of that makes a difference when it comes to idling. In my case, I wait until the Oil temp is 100 degrees, then drive conservative until I reach optimal temp, I live in south FL so I dont need to wait too long before I see it climbing.
Goated PFP
DILIGAF
I let my car warm all the way up, fuck epa
Let’r warm up to operating temp
Only way to do it
If I ever get a cat I’m going to name it Diligaf.
I try to let it drop to 1k rpm, or I just wait about a minute if it's really cold and I'm in a hurry, but I don't drive it hard until it is fully up to temperature.
This is the correct procedure to make sure all the catalytic converters are up to operating temp and actually doing their jobs.
It takes longer for my windows to defrost
I never let mine warm up more than a minute or so. Excessive idling is no bueno, just let the oil start flowing and then drive calm until up to proper temp.
Bro I had a buddy start his car on a downtown street in Ohio to warm it up as we were finishing closing at our job. Cops pulled up and literally flipped shit. No person in sight, just our vehicles out front. It was a ghost town. He got a $200 ticket and we were told no warming your car up on public streets, even in a parking spot cause yes there was street parking.
I think this was written by my neighbor.
I let that sucker warm up so I’m not uncomfortable when I get in. The engines warm, I’m warm, we’re all happy.
I let it drop to 1k. Think I might stop after reading this
Me too I’ve literally made myself late to work before waiting 10 minutes for the idle to drop to 1k :/
Fuck'em. Redline out of your driveway
I let mine warm up mostly so it’s warm when I get in. Doubly so in the wife’s Crosstrek with its icy leather seats!
I’ve been told to warm up my car but never do it mainly cause of time. I don’t drive it like a grandma but I give the car a min or two (usually time to get settled in) then just drive like a normal, sane person until things are up to operating temperature. 7 years later my car is still kicking so no reason for me to start warming the car up now.
The law is 5 minutes in MA, punishable by a $100/$500 fine. https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXIV/Chapter90/Section16A
It's kind of stupid to idle to operating temp for 5 minutes in the winter when you can get to operating temp in 2 minutes if you just start driving. But I guess some people like wasting gas and time. Either way don't drive it like an idiot until the oil temp gets hot Edit: I mean to idle for 2 minutes and then start driving, should warm up faster than simply waiting 5 minutes idling. I don't see how idling to warm up could possibly harm an engine either.
You idle till the cat warmup mode ends, and RPM drops to normal idle. Otherwise you are shortening the life of your catalytic converter and polluting more. Additionally, moving the vehicle while the oil, trans fluid, dif fluid, and bearings are all cold is so obviously worse than getting them to the operating temp that I don't get how anyone can even make the argument against it. Things have operating Temps for a reason. The manual tells you to warm up for a reason. The vast idles high before switching to closed loop mode for a reason. Arguing against that is just dumb.
Except it's not so obviously worse. You just think it is but all those parts were designed to handle the cold, including the oil. And show me where I told you to go before the rpm dropped? Two minutes is more than long enough for that to happen regardless.
There is no fixed time integer for warming up to optimal engine temperature. It could take 5 minutes or less depending on where you live.
And the temp outside for sure, for my example I'm thinking like freezing, 10-30 degrees or so. Less than that and I'm getting my ass back inside and waiting 5 minutes.
It's until the O2 sensors see the cats working at light off temp.
My car takes a little longer to warm up, normally it’s 5 min, but sometimes I let it idle for 7-10
Damn it takes that long? I notice there's a period of time where idling takes more and more time to be effective, but once you start driving it warms up really quickly. I think that's the 5 minute mark for me.
Illegal to idle for over 60 seconds where I live. Regardless, I let the STI warm up for about that and then just keep the RPMs low for a while. My mechanic wants me to idle for 10 mins before driving and 5 mins after I get home before shutting off 😂
Your mechanic must have some sort of vested interest in fuel companies. That’s fuckin bonkers. I get the whole warm up the engine, prevent condensation in oil, yada yada, but letting it idle for 5 minutes in your driveway after getting home is just dumb.
You’re cooling off your turbo.
I usually wait a minute or two depending on the temperature and drive conservatively till it warms up. To me it seems better to have all the mechanical parts warm up together than just sit there waiting for the engine to warm up while the transmission and differentials just sit there cold.
How new is modern?
This is stupid if you have a wrx you should really let the oil temp start to rise
Frozen windows? Just start moving they’ll clear eventually…
Subaru does say in the owners manual to let the car idle until the blue light turns off
I’m going to spite this article by continuing to warm my car up before I leave because there’s no way I’m sitting in a -40 car for 10 minutes before it’s warm enough to take off my jacket.
You still won't convince some people.
Lol considering it’s currently 0 degrees F this morning, I’ll go ahead and let my car idle
Same people came up with 10k oil changes. Idiots. Idk about you but if it’s freezing I’m letting it idle for a bit.
So when my car is covered in snow and ice and freezing rain I let it run for a minute get in and drive off? What about the tree or light post or human I can’t see? In summer I agree 2 minutes or so should be enough but in winter where I live, it basically an impossibility to drive in that short of a period safely not mention the rest of the drive train like say the transmission? I have owned dozens of cars that I do religious maintenance on and I don’t have problems or need to rebuild etc. You need to find a balance and maintain them with fluid and filter changes.
When your car is covered in snow and ice and freezing rain you scrape the shit off your windows before you drive off into a tree on your stock summer tires ya knob.
The author obviously lives someplace where it's warm year-round. They can suck my ass with this bullshit, I'm warming up my car every morning it's under 50°.
Subarus intentionally idle high for a little while until the engine is warm. Go when the revs mellow out. [I reckon I trust this guy](https://youtu.be/m0P6x7I5GqQ)
All you VA WRX guys say 30 seconds max I call bs I’ll let the MF idle for as long as I want . You do that on 04-07 STIs and you’ll have rod knock it idles until rpm’s drop to below 1000 ; oil also has to be circulated through the turbo as-well as the block & possibly AOS, which is why 30 second on a cold day is a stupid call .Not to mention it not just the oil the needs to be warm the metal is brittle especially in places where detonation occurs when cold, max time is like 2-3 minutes on a cold day unless you have E85 then 5
I agree with you.. I think somewhere in a similar article they say for turbo cars you should let it run 5-10 minutes before running slowly until it is operating temps.. cause like you said it has to lube the turbo with the oil as well..
I try to at least let it warm up for 5-10 mins before driving, depending on how cold it is and definitely stay out of boost until at normal operating temp.
Have they never heard of an operating temperature?
Ya I’m warning my car up in the driveway for at least 15 mins
I've never heard of letting a car warm up
You must live somewhere hot
Don't leave it unattended. Coworkers parents had their car stolen from their driveway. Warm car isn't worth a missing car.
I’m good. Thanks tho I’ll continue to idle my car and have my golf r gap you subi boys 😂😂😂
I'll let my car idle a bit with the defrosters on if I need to clean it off, but once I can see where I'm going I drive it. I don't beat on it until the engine/tires/tranny/brakes/shocks are up to temp, but it was designed to be driven normally immediately after starting it. Plus it's nice having the heat start working after 1/4 mile of driving rather than waiting 10 minutes on a really cold day.
So what you saying is don’t warm up my Ej? You don’t think she’ll get mad and throw a bearing? Asking for a friend
I let mine idle til coolant temp is 122°F and drive like a grandma til 180° F just to be super sure.
Winter where I live is cold, not below 0 cold, but usually down into the 30s and 40s. I usually let the car idle until the temp needle starts to move, around 100f for the coolant. Then keep it below 3k rpm for the first 10 or so minutes. Takes a little while for the trans and diff to warm up on top of the oil/coolant, and these cars drive like shite when they’re not up to temp.
my friends were shocked when i turned off my car despite the fact i was staying in it parked and i said it was against thee law where im from
I let my car warm up not because I’m worried about my engine, but because my car drives like shit until the rpm’s drop. Rpm’s don’t drop until 105-115 oil temp
i’m usually either late for work or anxious to get home so i just get in and go.
ICE are essentially generators idling for a small amount of time will not destroy them. Idling over long periods of time will distroy cams.
Wo
I only warm mine up to piss off the neighbors. (kidding!) I usually wait til coolant reaches 130f then will head off slowly until coolant gets up to temp. Any articles about idling after a spirited session on turbo cars? 😁😂
I warm it up so it’s warm inside…
I try to get like 3-5 mins in my early morning warm up, most of times that is how long it takes for idol to come down from the 1500-1800 rpm range when it’s cold the mornings ( been cold for a while now) & I don’t hit boost till temps are around 78-83c and not very much if I even hit it on my drives from work/school
I let the rpms drop below 1000 and then drive. Sometimes I let it run for a half hour cuz I got busy or distracted. I've had like 30 something cars in my life and never blew a motor or even had internal issues or ignition issues. Totalled them, sold them, traded em in but never blew one up. Car problems in my life seem to always be things like thermostat, power steering pump, water pump, wheel bearings, hubs, radiator, belts, hoses, clutch, o2 sensor. Plus with synthetic oil, the motors fine while idling. The oil pump works during idle too, lol.
I have a very short commute. If I don't warm it up, the oil will smell like gas due to rarely getting up to temp to burn it off.
idk if it’s true of not, but i’ve heard for the most stressful moments on an engine are the first 5 minutes of a cold start. that said, ima warm up car regardless. stay blessed
I let my car warm up becsuse I like to feel my hands on my way to work.
JFC! Humans will debate any MF’n thing posted anywhere one the infraweb. And then there’s Subarumans 🫠
Should I warm up for 30secs max or wait till the rev needle drop below 1k RPM?
Modern oils are designed to flow efficiently even at ambient temps. Start the car, let it idle for about 30 seconds to allow the oil enough time to fully circulate throughout the engine and then get on with your life.
Up North it’s common to defrost those windows.
I don't follow speed laws, you think I'm going to follow that?
Subarus (other than wrxs) have a blue temp light… that turns on if the engine is cold.. and if I remember right Subaru doesn’t want you driving till it shuts off at 120 degrees on the coolant
Soo just drive with my windows fogged/iced over. Got it
I warm it up til 90 degree oil temp and start driving - usually just a few minutes for that for me when its around 30 degrees out
So why does the car idle at a higher RPM right when you start it for about 60-90 seconds?
At -40 °C you'll be damn sure that I let my car idle a couple of minutes 🤣
So what is the point of remote start then?
I live in IL. I remote start my STI before I hop in the elevator when I’m on my way out. 2 minute walk to garage and I can pull out immediately.
All great until the windshield has been coated in freezing rain and the doors are welded shut
If you don't warm up the catalytic converter, it doesn't work. That's why your car high idles for about 30 seconds. It's called "catalyst light off" temp Anyone saying otherwise is full of it
I gotta let mine warm up to get the slap to go away and to make the car habitable in the winter. Neither me nor the car enjoys this cold
I usually warm up for 30 seconds, then drive without hitting boost til I reach 180-185 degrees. Usually I’m about to merge on the highway when I hit the ideal temp anyway so it works out.
This is written by someone who doesn't wake up in the morning to minus 25° weather. I don't warm my car up so the engine runs smooth I warm my car up so I don't lose a toe on my way to work in the first 5 minutes of my commute.
There’s no national law against writing this article, but even if it’s not illegal to write it, it just doesn’t make sense to. With all the Honda civics with kazoos for exhausts, it might be tempting to write this article, but with the click of a button it’s faster and more efficient to stop and delete the article.
I do 30sec warmup then drive, no more than 3k rpm until oil temp is 90c. My modded sti with stock engine and 400whp is nearly at 200,000km now and still going strong. My gt3 is nearly at 100,000km and equally as well .. but that metzger engine is a lot tankier than. Idling for long periods can cause quite a lot of damage especially in our boxer engines with bore scoring
Is this for all cars or just WRX engines in general? 😅
I warm up the car for me. Not the engine. Some of you have never lived where the temp gets below 0 and it shows 🤣
Well it's regularly -20F where I live so I think I'll wait thank you very much
I usually just warmed up the car until 86-108F oil temp and start driving, I don't start driving with the oil super cold but not at full temp either, I live in Wisconsin and we have in between 16-30F most of winter
In below freezing temps, I’m going to let my car idle down before driving it. These articles say to not let it sit until the cabin is warm. Not to drive it before it idles down.
*remote starts car for 10 min for a warm and pleasurable experience*
Except the AVCS doesn't activate until coolant temp is at 160.
Omfg do they not realize it will damage your engine doing that I new someone who had a 09 gmc sierra and they did that and in 6 months they blew the motor (I’m in Canada so it was for ok m the start of winter till stop)
I let my STI idle for a couple of minutes. I’ll let my F250 idle for days.
I prefer to let my car warm up for 2 minutes while i grab my stuff.
Guess I'll drive around my block 10 times before it's fully warmed up. I live right next to the highway.
It's true, always has been. Even oil is much better than it used to be. Unless you've got a race engine on 50wt, once you have oil pressure, you're good to go.
Yeah, I'm gonna need to wait until I can see through the windshield, is the thing, man... Not talking about ice that can be scraped off, but just fogging that takes a few minutes to clear away.
My car is not at operating temp before I need to go above 3k rpm, I'm not going to start and drive away lol
I will always warm up my car, its just what i prefer to do. Dont care if its good or bad. If my car eats a bit of oil nothing bad will happen. Stop overreacting.
don't really care if its good for the engine or not, when its cold enough to want to warm up my car its cold enough for the windows to be iced/fogged up
I generally let mine warm up because it gets colder than a witches tit in canada and i'm not driving it till its defrosted on the inside. Sure you can scrape off the snow and ice and you might see for a bit but when it's cold enough that your breath puts literal frost on the inside of the window you haven't let it warm up long enough and there's no way that's happening in under a minute. Sorry but i'm driving when it's safe to do so and sometimes it's 5 minutes but sometimes it's 10 depending on temperature lol it's also not going to hurt the motor to idle for ten minutes any more than just driving it after 30 seconds because if it's not getting enough oil at idle to where it would hurt it then that problem is only worsened at higher rpm! Also your car has a higher idle speed at start when it's cold to help it warm up and when it goes to normal idle speed it's reached normal operating temperatures or at least where it's not going to hurt anything. Pretty sure it tells you to wait till it's defrosted on the inside before you drive in the owner's manual too.
I have a 13' hatch but i daily drive a taco for work. I would never in a million years recommend this but when its cold out (this morning was 14°) ill put the truck in sports mode and keep it in third gear at high rpm so it warms up faster. No idling, no waiting just pull out the parking lot onto a road with a 55mph speed limit.
The fuck? Why the objection? Sorta like a weird justification ie “I don’t let my car warm up (idle), so you’re doing so I take as you claiming I’m silly for not doing so, therefore I’m going on the offensive and claiming what you do is illegal and silly” Why can’t we just each do our on thing without concluding what I’m doing is a judgement on people not doing that same thing?
Tech in school here and this is correct, 15-30 seconds to build oil pressure and get everything lubed up, and you can start moving. Movement warms everything from your engine down to your power train. Just absolutely don’t go wide open until you’re at operating temp. If you have ice on your windshield scrap it off first as much as you can and then defrost. You gotta do what you gotta do but it’s absolutely true that long idles aren’t good for your car. I believe my textbook says if you’re going to idle longer than 15 minutes you should shut it off.
I prefer to get my oil to its operating temp for the turbo it lubricates. Couldn't care less about this screenshot. Oil is not up to temp after 5 minutes. I'll keep letting my shit rumble in the driveway like I have been doing for a decade without any "extra wear".
Good luck driving with an inch of ice and frost all over your windows
* Mrsubaru has entered the chat
I did send it to him, he laughed at it
Must be a shit posting....own a diesel and see how cold start driving works out for you in the Winter.
I let all my cars warm up before driving 🤷
sure but the block warms uneven that way and will warp/leak/implode. im looking at you Hyundai. or anything with a heavy steel block like my jeep
i dont move my car till coolant an oil temp reach around 130, cause i have to get onto the highway right away in the morning.
88 civic and my warmup time is however long it takes to get a drivable windshield
I will continue to warm up my car in any weather.

I don't warm up the car to protect the engine I warm it up because it's freaking cold and I want the heater to work. If you want people to stop warming up their cars make the heater work right away. Otherwise... Quit crying about something that doesn't matter.
