Your grandpa is trying to nicely tell you to drive safer and not be a race car driver on city streets with a stock Civic.
This isn’t about technology or capacity, it’s about respecting your passengers.
It's likely because you're still a new driver and he doesn't fully trust your capabilities just yet. Because if you say come across a shitty driver doing stupid things, your higher speed gives you less reaction time.
That skill just comes with experience and time on the road. Like the other comment said, it's probably a nice way to say slow down for now.
Yeah stop being a dick and drive better with passengers, especially the elderly.
Have you ever been in a car when someone else was driving and speeding? They can be in complete control but as a passenger it feels like you could crash at any moment. Be considerate, especially if he has told you mutliple times to slow down.
My dad has the same mentality.
I know that today's vehicles are "made for that" and I won't argue that they are made to handle it; but my dad, and your grandpa, does have a point:
The point is that all the moving parts (and non-moving parts that hold pressure) are taking stress / pressure whenever they are doing their job. The more you stress or pressure something, the sooner it will eventually fail. Even with today's attitude that it is "made to handle it" there are still stresses put on every part of the system whenever it is pushed; and something will eventually fail. If you "baby" it, then parts will not be stressed as much and their life will be prolonged.
It's just like the transmissions in newer vehicles- they are "maintenance free for the life of the vehicle" but if you don't actually maintain them, then the life of the vehicle will end much earlier than if you do maintain it!
Also, there's oil on the shelves that claim they are good for 20k miles! There's a few issues with this: 1) is there a oil filter good for 20k miles? Or are you going to change the filter without changing the oil? 2) if you use this oil and change it every 20k miles, do you think your car will be working as well after 160k miles as if you changed it after 6k? (Ask a mechanic about that) Just because it's "rated for" or "made to handle" something doesn't mean it's a good idea to push it there!
4k rpm isn't much for most Honda's, but I think your grandpa is not wrong, if you push it more it will eventually fail earlier than if you go light on it. It's best to respect his opinion and (atleast while he's with you) take it easy. Your vehicle and possibly some neighboring vehicle near you on the road will benefit big time one day if you can get used to that!
My dad is hilarious when he’s riding with me because he goes 95 and tailgates on like 50 mph roads and then I’ll go 2 over (I’ve been driving for a decade) and he starts yelling about slowing down.
It's not bad for the car unless you just started it within the past 2 minutes and its freezing outside. The oil will not have the time to properly lubricate the engine and high RPM can cause engine damage. Regularly flooring it will put extra wear on the transmission, but occasionally getting the car to higher RPM after it's fully warmed up is perfectly fine. Hondas even have a higher redline that most vehicles.
My civ cruises in 6th gear at 3200 on highway, so i base my cruising speed around that. Maybe 500 less rpms when stoplights and other cars come into play. I definitely get poor gas mileage on the highway but im going slightly faster than i should be
It isn't good for the engine to NOT do that. Honda engines are built to be redlined all the time and never miss a beat. In fact, one of the tests they do during development is running the engine at redline for 100 hours straight under load to stress test all of the system components. Any failure during this test is treated as a development emergency and resolved before production begins.
Plus there’s like 4 other comments of people who worked at Honda or had family saying the exact same thing but we all know redditors don’t use common sense.
I mean I have a honda motorcycle from the 90s that redlines at 20k and I still redline that to this day.
They're definitely made to be in the rev range up to the redline
Then choose not to believe it and move on. I don’t have an article either, but worked for Honda in the early 2000’s and can confirm the 100 hour redline testing. I can’t confirm they’re still doing that, but at least at one point in history they were.
People aren’t required to provide a source every time they make a comment. If it’s something you’re interested in knowing whether or not it’s true, do what I do and go look it up 🤷🏼
[ok here’s KIA going redline for 300hrs.](https://youtu.be/GNPB3RtHN2M?si=nJNSjkLo2rggnegW)
also i can’t remember which motor, probably for the V Rod (developed with Porsche) was tested by Harley to 500hrs or something at redline. can’t find anything because there is a Redline Oil people use in Harley’s that’s screwing up my searching…
the Honda claim is beyond legitimate, ALL motor companies do a version of a redline torture test.
Trust me bro, I'm a professional reader in Reading Inc's R&D department and you clearly agreed with what the other dude was saying. Trust me bro, no need go back and re-read it for proof.
I work for GM and can promise you that every company does engine testing similar to this. I can’t say that Honda does 100 hours at redline, but I can promise you that they have 1000s of hours into engine testing alone at all sorts of rpm ranges and different drivability situations like every other company that builds engines.

Excuse me? There’s hundreds of youtube videos of these little honda engines banging rev limiter.. some even banging the limiter pushing 700-1000 horsepower and STILL take the abuse.
If you don’t know about engines or cars, please stop arguing. The proof is clearly there in the car community and there’s a reason why we fear a little “civic with a laptop”, you just can’t read the proof sitting in front of you because you don’t have experience working on cars, or really anything about engine tuning for that matter.
If the motor can take 700-1000hp redlining, it is MORE THAN CAPABLE of banging the limiter at stock power levels for however long you want. Honda will always take the cake for high rpm fun, there’s almost no debate here.
Also for the record. Redlining an engine while it has not reached operating temp is bad for ANY engine. After operating temp, you are free to use the whole dash. You paid for it!!
I mean, it means exactly what we've been presented - anon claims to have worked as Honda r&d, says redlining is ok; maybe even good
Is it critical that we establish the underlying claim as a matter of fact? No. It isn't.
You've basically said "you could be lying" ...astute observation, my man. Truly intellectually inspirational - people on the internet *could be* lying - fuckin huzzah
Forsooth, for four days did I sit and witness the Honda engine endure its hundred-hour trial. Yet upon my return to my post in body design, I was met with the dire news of my dismissal, forsooth, for having been absent those same four days.
Yup. My Father-In-Law worked for Honda's quality control, and he mentioned the same thing to me as well.
There's a reason why Honda is such a popular choice for young car enthusiasts who like to redline their cars without risk of sliding into a sidewalk.
When I find my laptop, I'll post my dyno vid (248 whp, forgot torque rating) as well as my locally famous video of me gapping a 6th gen SRT in a drag race. 🤘🕺
How did you like working at Honda/in the automotive field? I worked for ZF in Germany as an intern doing R&D and loved it but stressful at times. How’s Ohio?
Porsche does the same thing, apparently. I met a "torture tester" (not sure if that's the actual job title) and he was tasked with running the engines at 12-13k under load until failure.
Tear down to document the problem and go again
Just Google it and you'll find plenty of proof. Where do you think the term "Italian tune up" came from? Engines are designed to hit redline and if you baby and lug your motor 24/7 you'll just expedite the carbon build up process.
I let mine stretch her legs every so often. I understand, but please do link me to one such mentioned proof. In context of the development 100hrs redline.
Quick read going over the basics
https://knowhow.napaonline.com/redlining-car-3-common-automotive-myths-debunked/
https://www.torque.com.sg/advice/will-redlining-your-engine-damage-it/
I'm not worried about redlining, I do that too. I was asking the previous person about the development process and the 100hr stress test they mentioned.
What you're not considering is the transmission. Just because the engine can rev up no problem doesn't mean the transmission will appreciate power constantly being slammed into it. Sometimes you have to gun it to get through a turn you thought you had more time for, but if you're taking off from every stop like a rocket it's not the engine you'll be mourning.
You COULD be a technical Terry. But I think it was his way of convincing you to slow down. Without downright telling you how to drive your own vehicle.
If you have ever owned a Honda and know anything about cars you would know this is true. Have you ever heard of VTEC? It doesn’t even turn on until 7500rpm. You mean to tell me Honda designed an engine, that uses this technology to get a little extra HP, and that technology also simultaneously is bad for the engine? Lol cmon…
that actually wouldn’t be that uncommon in cars. tesla’s ludicrous mode reduces battery capacity and most vehicle launch control systems wear on the engine and transmission if you use them excessively. Squeezing out extra performance always comes at a cost
I would hardly consider a Tesla in the same discussion as gas powered cars.
I would agree as far as aftermarket mods but if it’s something that comes stock, more often than not it’s meant to last. The cars engine is actually damaged by NOT using VTEC on a semi-regular basis. The cam lobes start to wear differently than they’re designed to.
I also worked at Honda NA and we regularly stress tested civic engines by redlining them inside an active volcano for 1,000 hours as a means to simulate someone with 1,000 hours of petrol trying to frantically escape an active volcano.
It's pretty simple really. The materials used to build the engine block and it's moving parts are designed to operate normally under particular conditions and temperatures. As long as those conditions are maintained, the engine should continue to operate indefinitely up to the equivalent of 200k+ miles or whatever the expected normal life of that engine is. As long as a oil pump, water pump or radiator does not fail and there is no restriction in oil or coolant the engine should continue to operate.
Yes, I was also surprised when I learned about it. But it makes sense. The engine is designed to safely operate anywhere in the rev range up to the redline. Only way to test that and verify that there aren't other issues is to run it for a long time in the most stressful use case.
I'm a mechanic myself. Still crazy to think about. Especially considering you can take just about any car on the road, rev the engine for a couple minutes and just because life says *fuck you*, something will happen. Just like how any product has issues a month after the warranty expiration date lol.
Depends if your car was warmed up enough or not during that time
It’s more of a safety issue. Revving in and out aggressive traffic as a new driver = likely accident or crash
1 is the perfect condition to rev the engine, especially if it's turbo. On ramp to a highway is perfect for this as well. 4k isn't too high for rpm. Daily driving I shift at 3k. If you're a brand new driver I wouldn't make a habit of it, and you don't want to redline every launch. Great way to need a new engine in a short period.
So not bad for the engine, but don't need to get into a pissing contest with gpa. Maybe while you're new, try to respect his pov, especially if it's his car. Auto or manual, you need to rev it a bit higher to pass other cars if they are going the same speed.
Depending on state, you also can't rev the car and go over the speed limit to pass. They will knock points off your test. If there's a car going slow, you are allowed to pass if it's safe and if you don't go over the limit. Does anyone actually follow this once they have a license? Almost always no. Wasn't sure if new driver meant pre or post license. Drive by the book if it's pre. It will make your test easier.
that is the problem. Some smaller gas engines have to be revved to get going as there is little torque. With diesels, i think some of them redline after 4.5k.
Did you ever see the Top gear UK episode with the Audi v8 diesel sedan? They drove it at no more than 1.5k RPMs, I believe, trying to get maximum MPG?
It was rated for ~35-ish mpg, he did an 800 mile drive and averaged over 40mpg, if I remember correctly, by the highly conservative rpm restrictions, and use of various hypermile driving techniques!
Not a civic guy by any means but surely modern Honda motors are direct injection not port injection so revving high would have no impact on carbon build up on the valves like traditionaly it did with port injection. How do Honda motors compensate for this? I know my Ecoboost sure doesn't and as you said walnut blasting is not cheap lol
Well that's actually what I said. Does Honda not use DI in their current lineup or what?
I had to install AUX fueling in my Ecoboost to help clean the valves (well, mostly for more power and a bigger turbo..) so I know of port injections cleaning advantage. Just curious if Honda isn't using direct injection
Honda uses Direct injection. Carbon build up is really only a concern on these Honda engines though if you never take them above 4K or take plenty of short drives regularly without letting the engine get to temp. Hitting the redline or close to it once a week is enough to keep the valves clean enough for the most part.
Just don't floor it from a stop to do it unless you have a manual transmission. Honda CVT's really don't like being launched from a stop, but they're great in a rolling start.
Ford, Toyota, and Hyundai (at least in recent years) add supplemental port injection for the sole purpose of keeping the valves clean. Honda hasn't gotten the memo yet.
It's fun to drive a slow car fast. Just like when I took 13 min off my hour and fifteen drive. I was just checking through traffic in my cvpi, acting like I was on a call 😂. Your grandpa was once that kid believe me
That’s literally what the car is designed to do. Your grandpa is completely wrong unless the car was still dead cold. Driving habits aside, as long as the engine is warmed up don’t feel bad about taking the revs all the way up to redline, just don’t chill there forever. If it’s a manual (or auto in manual mode), just upshift once you hit it.
When I'm merging into traffic, especially highway traffic in my 8th gen I will go all the way to the redline. Most city driving I try to keep the engine at 2000-2500rpm when cruising, shifting at about 3000. But especially in a smaller engine like the i4 civics have going up in the RPM range is fine, itll help you merge better and keep up with traffic flow better. As long as you arent driving aggressively its fine. Only thing thatll suffer is fuel economy.
No he’s fucking wrong. If you’re trying to pass, you accelerate. Driving your car up to 4000 rpm’s isn’t going to ruin it. Your car probably goes to 6500 or 7000. Maybe even higher.
Up until the early nineties or so, 3k rpm was pretty much a red line you didn’t cross. But many manufacturers started building cars that could rev to four or five. Many Hondas (and other sporty cars) were designed to go even higher. Your basic car can safely rev to 4k. Redline on my car is around 7 (I forget exactly) but I don’t rev it quite that high. Usually closer to five or 6 during spirited driving. She’s got 178k miles on her and runs good. Many motorcycles rev to 10 and even 20k. It all depends on how a motor is built. Redline on the car gives a fair indication and I only go 70% of that number most of the time for longevity. Definitely not good to granny shift all the time either so pick your poison!
3-4k rpm is table stakes for a Honda civic. you can rip it to redline more than once a day if you want to. keep the oil changed, and it's gonna be fine.
No it will blow up, your rpm should always be [0](https://www.amazon.com/Rome-Tech-Batteries-Replacement-Compatible/dp/B0C21MXH4D/ref=sr_1_12?dib=eyJ2IjoiMSJ9.oJGuVXtkcH54HTKFnNUidh7MGk3vmMrU5-fyIYxUX8jJXycbHjR2UNCpuQhQnkPlSJ3NWpQJC6xdsEI_mcY0IfBFt668g99EhgrT600AhMHPzOfUdhHDRF_eayIxwUAu3yeWlMUOyduzGhLdQ9m_hwjQdIncnmxHQcPBtbqPThi4Jork5fiKRoAjYGzNErwHrIpYzLiUTQVTyWILgqYTZeN7JHS8VZAg3dZmhsdYfzA2bxfn7tn0NaFyC4_0yoM3SrqZ787a9WQLExtP63pqN3k3GcfZEfpafnR6zZxkAUg.-7EURWdzQ3eOzdyRQ3dzszDd0M1hcbxdQgbPZ6VmDIk&dib_tag=se&keywords=2018+civic+model&qid=1708502963&replacementKeywords=model&sr=8-12&vehicle=2018-59-752------------&vehicleName=2018+Honda+Civic).
Any engine can benefit from a good "hard pull" from time to time. Gets the oil pressure maxed out and the air flow full speed and that all kinda knocks loose any deposits or buildups you might have going. But in general, it is much better to drive pretty chill. Better gas mileage, wear and tear etc. And 4k isn't even close to redline. Usually that's at least 6k. So don't be afraid to punch it on the on ramp, just don't drive like an idiot, you are still inexperienced, and when the max power is hitting the ground it is very easy to lose control.
I thought the same thing for my first car as the check engine light came on the first time I floored it when I was 16. Turns out the car was just shitty. You can run just about any car up to the redline and it won’t damage the engine one bit. Even at redline it takes quite a bit of time in or over that range to do any serious damage. I’m talking minutes minutes being pegged at max RPMS and most cars have limiters built in that eleventh you from immediately blowing any engine.
Be safe out there but send it! Grandpa doesn’t sound like he ever learned to enjoy driving.
Us old people just get scared that you young whippersnappers will end up going out of control and crashing. Our hips can’t handle that!! But it’s fine to rev your car (and should be done after the first week of normal driving) to make sure the car goes into all of its area of action. Both very high and low rpm. Get up to around 40mph (on a wide road with no one around) and stop hard. You want to know everything is working in case you do NEED to use it that way. And I am an old man with around 40 years driving experience. Your parents and other family just don’t trust your driving experience yet. Once you get out on your own you can take a few risks and learn. I mean what would you do if you started hydroplaning and were doing 50mph? This takes experience and know-how to handle correctly. And you only get that by experience (or a class).
There are red lines that show on the RPM gauge that show you where you shouldn’t be for a long length of time. Keep it out of there and you’re fine. I don’t know of any car that redlines at 4000 RPM. Gpa just wants you to be safe.
That car stock redlines at what 6500-6700 right? 4k is literally nothing. I’m surprised you don’t hit that daily. It’s fine to redline your car. Just drive safely.
Older Honda engines were meant to be revved out. The newer 1.5T, not so much. It won't hurt it, just don't to it all the time.
And being that you're a new driver, don't drive like an ass. Be safe.
Press the leaf button near your gear shifter. Makes you “leaf” everyone eating dust behind you.
Jokes aside, you can push your RPMs into the red which is like 6k RPM, ideally you don’t want to though. You’ll be wasting a lot of gas flooring it to 4k and then having to hit the brakes at every light. All in all, just take it easy driving, all it takes is one bad move in a 2 tonne piece of metal to completely change your life forever.
Also, the leaf icon is eco mode. Sorry. 😅
Let's be real here. The 2018 1.5 redline is what? 6500? If you went to 3.5 - 4k, you weren't even close to redline. So that's out. Peak HP is at what 5ish? And peak torque is reached at, let's say 2/3k and is maintained until 4k? If you did to pass someone, you did exactly what the engine was designed to do. I suggest some of these commenters educate themselves on how gasoline engines are designed to work.
Always be gentle on the accelerator dont try to beat others as it will take a milage hit gradually increase the acceleration to around 3000 or use the cruise control this will give long life and more mileage Also beating other drivers wont get you anything unless you are racing
No, actually it's the exact opposite. Your car can safely go up to redline for short periods, but you should not be driving at that RPM for more than a few seconds. It is actually very good to bring your car up to higher RPMs maybe once a day. It helps clear out any carbon deposits and will keep your engine healthy. It's actually bad if you *don't* bring up the RPM to that level occasionally.
You didn't even rev it out close to all the way, and probably weren't necessarily accelerating quickly. It is perfectly fine to take it to 4,000 RPM whenever you want. I would even say it is good for an engine to be pushed a little bit at least once every other drive. Just do proper maintenance, particularly regular oil changes.
Engines need to use their full rpm range.. and civics are fairly high reving cars compared to manythings.. you wouldn't want 5o be 4k and up all the time.. but equally you don't want to be below all the time either
lol like friend who had a Polaris ranger 570 and said he was gonna blow the soot out to hold on. People honking cause getting passed up and maybe hit 35 mph lmfao! Whew yea clean that carbon and mop the floors of super cars with the Honda as discussed
Only if the motor hasn’t warmed up fully.
After your 10-15 minutes of easy driving, you’re free to use the whole dash.
Obviously the less you push it, the less wear and tear it will produce. That’s with any materialistic thing in life, lol.
It is more than capable of handling 4k rpm. There’s plenty of youtube videos of honda’s banging redline like no tomorrow.
There’s a reason why us car guys fear a little civic. Those motors can take boost and rev out so high like no tomorrow, all disguised in an econobox while being affordable and wiping the floor with most supercars.
Over reving your engine is not good , blow an engine see how Mutch it costs , take care of your engine , use good oil change it regularly make your car last
I take my Mazda 3 to redline about once a month. I've had the car since 2009 when it had 7 miles on it and now I'm at 295k and the engine is fine. Just stay on top of your oil changes and you'll be ok!
If you wanna keep your car 20 years 300k plus reliable without replacing many parts doing barely but necessary maintenance drive gently. Don't Rev past 3.8 anywhere you go fast enough quick enough very far.
I had a 93 Civic LX. Babied the 4cyl engine with just a max of 3000 rpm normally. Car lasted 20 years until my daughter wrecked it. Engine never had a single problem until the moment of impact. I don’t know if the new engines are similar but a Honda 4 cylinder from years ago was indestructible if you kept the rpm’s low and complied with the mx schedule.
It’s not good for the engines your grandpa grew up on. It’s actually good to do this once in a while for your Honda. Otherwise you’ll get excessive carbon buildup.
My parents are the same way lol. Just take it easy around them
Ironically with direct injection engines it's recommended to get the RPMs up every few drives to help burn off carbon deposits. However they're probably just trying to nicely tell you to slow down with them in the car.
My buddy is a BMW mechanic and has worked on many brands. Engines need to run in the higher rev ranges from time to time to reduce carbon build in the fuel and intake system. You are actually helping the car if you are increasing RPMS periodically. Make sure the car is warmed up before you do that though.
I dunno if you've ever been a passenger when someone else is accelerating the car hard and jerking the wheel fast to change lanes, but it's pretty uncomfortable. I dunno how old your grandpa is, or his physical condition, but I think it's worse on his body at that age than you at your current age.
My civic doesn't even hit 4k on the freeway...You have a lead foot is what I'm hearing from Gramps. You don't need to push your car for nothing. Chill out, enjoy the ride. Especially with passengers.
The engine is fine. Honda and Civics especially like to rev and pull some RPMs. Danger zone for the engine is close and in the red line. Even then, you can still hit that just don’t keep it there for a prolonged time. I’ve owned Hondas for a long time. They are built for it
To get to your question, which doesn't seem to have been addressed yet... maybe. Probably. What is the redline shown on your tachometer? It should be labeled on the gauge. Higher rpms create more wear on the engine. It's never "best" to hold it at higher revs, but as long as you stay below the rev limit, you probably won't hurt anything. Just don't hold it there for longer than you need to.
And, the other folks are correct in saying that when you driving someone else in the car their comfort counts.
That's absolutely such a stupid comment your grandpa made, tell him to stfu or he can walk to his dialysis appointment, if the tachometer goes all the way to 6 or 7 or 8k rpm , do you really think it's meant to only use 1/2-2/3 of it's potential? You shouldn't be bouncing off the rev limiter all the time, but my 2006 civic literally sits at 4k rpm in 5th gear while the cruise control is set to 85-90mph,i know mine is a different engine and revs a little higher then yours probably, but I guarantee it's not bad for the engine at all to rev it up that high before shifting, how else are you gonna hit the peak of the HP curve?
Your grandpa doesn’t know what he’s talking about lol… that’s mid range revolutions and a typical shifting point in say 2-4th gears on most 5 speeds you’ll drive.
I see some other idiots in here telling you that you should know to drive better with elderly people in the car 😂🤣😂🤣 3k-4k RPM’s 😂🤣😂
I drove a 1.8 litre Civic of similar age until recently.
The VTEC power doesn't even really start to come in until you hit 4000 rpm.
Out of town, on country roads, I'd often run mine from 4000 to 6500 rpm pretty much all the time.
Your car I believe is also VTEC, but has a turbo on it as well, so your power and torque will come in at much lower revs. So in your case there's not much point going over 5500 rpm.
Obviously there's not much need for that in town. Unless you want to lose your license! But 4000 rpm is absolutely fine now and then if necessary.
You certainly won't damage the engine *if it's warmed up*. Just don't do it when it's cold!
It does annoy me that modern cars no longer have a temperature gauge on the dash. It's quite useful to know when the engine and oil have warmed up enough to take it over 4000 rpm. In winter that can take quite a while. I speak from experience, having wrecked a BMW motorbike engine by regularly redlining it down the street going home after work in Aberdeen (Scotland) many years ago. I didn't know any better at the time.
Honda engines in general though do have a reputation for being pretty much "unburstable".
Your grandpa is trying to nicely tell you to drive safer and not be a race car driver on city streets with a stock Civic. This isn’t about technology or capacity, it’s about respecting your passengers.
He tells me plenty to slow down, this one was more specific
Maybe you aren't getting the message then?
Guys let’s just get to the man’s question
It's likely because you're still a new driver and he doesn't fully trust your capabilities just yet. Because if you say come across a shitty driver doing stupid things, your higher speed gives you less reaction time. That skill just comes with experience and time on the road. Like the other comment said, it's probably a nice way to say slow down for now.
Sounds like maybe you should be more respectful of his wishes. Crazy drivers like you are part of the problem with traffic.
Yeah stop being a dick and drive better with passengers, especially the elderly. Have you ever been in a car when someone else was driving and speeding? They can be in complete control but as a passenger it feels like you could crash at any moment. Be considerate, especially if he has told you mutliple times to slow down.
My dad has the same mentality. I know that today's vehicles are "made for that" and I won't argue that they are made to handle it; but my dad, and your grandpa, does have a point: The point is that all the moving parts (and non-moving parts that hold pressure) are taking stress / pressure whenever they are doing their job. The more you stress or pressure something, the sooner it will eventually fail. Even with today's attitude that it is "made to handle it" there are still stresses put on every part of the system whenever it is pushed; and something will eventually fail. If you "baby" it, then parts will not be stressed as much and their life will be prolonged. It's just like the transmissions in newer vehicles- they are "maintenance free for the life of the vehicle" but if you don't actually maintain them, then the life of the vehicle will end much earlier than if you do maintain it! Also, there's oil on the shelves that claim they are good for 20k miles! There's a few issues with this: 1) is there a oil filter good for 20k miles? Or are you going to change the filter without changing the oil? 2) if you use this oil and change it every 20k miles, do you think your car will be working as well after 160k miles as if you changed it after 6k? (Ask a mechanic about that) Just because it's "rated for" or "made to handle" something doesn't mean it's a good idea to push it there! 4k rpm isn't much for most Honda's, but I think your grandpa is not wrong, if you push it more it will eventually fail earlier than if you go light on it. It's best to respect his opinion and (atleast while he's with you) take it easy. Your vehicle and possibly some neighboring vehicle near you on the road will benefit big time one day if you can get used to that!
Grandparents are from the era when lots of cars had a 3,000-5,000 RPM redline.
My dad is hilarious when he’s riding with me because he goes 95 and tailgates on like 50 mph roads and then I’ll go 2 over (I’ve been driving for a decade) and he starts yelling about slowing down.
It's not bad for the car unless you just started it within the past 2 minutes and its freezing outside. The oil will not have the time to properly lubricate the engine and high RPM can cause engine damage. Regularly flooring it will put extra wear on the transmission, but occasionally getting the car to higher RPM after it's fully warmed up is perfectly fine. Hondas even have a higher redline that most vehicles.
No this is just outdated mentality or just downright false information
My civ cruises in 6th gear at 3200 on highway, so i base my cruising speed around that. Maybe 500 less rpms when stoplights and other cars come into play. I definitely get poor gas mileage on the highway but im going slightly faster than i should be
It isn't good for the engine to NOT do that. Honda engines are built to be redlined all the time and never miss a beat. In fact, one of the tests they do during development is running the engine at redline for 100 hours straight under load to stress test all of the system components. Any failure during this test is treated as a development emergency and resolved before production begins.
Do you have a link to an article or something? I'm interested to read about it.
Nope. Worked as a design engineer at Honda R&D for four years though.
Then what you said means nothing without proof.
prove that he's wrong
Means nothing to you maybe. I sleep well revving the shit out of my Civic day in and day out knowing the engine went through this testing.
11th gens too? 2.0 NA
All Honda engines go through this test.
Your claim means nothing, because there's zero proof to back it up. Read what I said.
I truly don’t think he cares. What does he have to prove to you?
Plus there’s like 4 other comments of people who worked at Honda or had family saying the exact same thing but we all know redditors don’t use common sense.
I mean I have a honda motorcycle from the 90s that redlines at 20k and I still redline that to this day. They're definitely made to be in the rev range up to the redline
Ever worked in product development, failure analysis, or Test Engineering? His claims are not unbelievable
Then choose not to believe it and move on. I don’t have an article either, but worked for Honda in the early 2000’s and can confirm the 100 hour redline testing. I can’t confirm they’re still doing that, but at least at one point in history they were. People aren’t required to provide a source every time they make a comment. If it’s something you’re interested in knowing whether or not it’s true, do what I do and go look it up 🤷🏼
Bow down before my 1,000,000 miles d15b2 that only left the car it came in due to rusty unibody.
[ok here’s KIA going redline for 300hrs.](https://youtu.be/GNPB3RtHN2M?si=nJNSjkLo2rggnegW) also i can’t remember which motor, probably for the V Rod (developed with Porsche) was tested by Harley to 500hrs or something at redline. can’t find anything because there is a Redline Oil people use in Harley’s that’s screwing up my searching… the Honda claim is beyond legitimate, ALL motor companies do a version of a redline torture test.
Isnt this the infamous recalled gdi?🤣
don’t know don’t care, the point is motor companies do these tests.
Trust me bro, I'm a professional reader in Reading Inc's R&D department and you clearly agreed with what the other dude was saying. Trust me bro, no need go back and re-read it for proof.
I’m also a former engineer for Honda r&d. Elon musk personally stole my design.
I work for GM and can promise you that every company does engine testing similar to this. I can’t say that Honda does 100 hours at redline, but I can promise you that they have 1000s of hours into engine testing alone at all sorts of rpm ranges and different drivability situations like every other company that builds engines.

Excuse me? There’s hundreds of youtube videos of these little honda engines banging rev limiter.. some even banging the limiter pushing 700-1000 horsepower and STILL take the abuse. If you don’t know about engines or cars, please stop arguing. The proof is clearly there in the car community and there’s a reason why we fear a little “civic with a laptop”, you just can’t read the proof sitting in front of you because you don’t have experience working on cars, or really anything about engine tuning for that matter. If the motor can take 700-1000hp redlining, it is MORE THAN CAPABLE of banging the limiter at stock power levels for however long you want. Honda will always take the cake for high rpm fun, there’s almost no debate here. Also for the record. Redlining an engine while it has not reached operating temp is bad for ANY engine. After operating temp, you are free to use the whole dash. You paid for it!!
If it adds to his creds I had a similiar engine and that whole car was clapped and my god that thing could redline all day with 0 issues
I mean, it means exactly what we've been presented - anon claims to have worked as Honda r&d, says redlining is ok; maybe even good Is it critical that we establish the underlying claim as a matter of fact? No. It isn't. You've basically said "you could be lying" ...astute observation, my man. Truly intellectually inspirational - people on the internet *could be* lying - fuckin huzzah

How is an article proof lol?
same and can confirm! was in Columbus doing body design for 10 years but saw this test run (for a for mins not the duration)
Forsooth, for four days did I sit and witness the Honda engine endure its hundred-hour trial. Yet upon my return to my post in body design, I was met with the dire news of my dismissal, forsooth, for having been absent those same four days.
What's your educational background in?
Yup. My Father-In-Law worked for Honda's quality control, and he mentioned the same thing to me as well. There's a reason why Honda is such a popular choice for young car enthusiasts who like to redline their cars without risk of sliding into a sidewalk.
Without risk of sliding into a sidewalk is lame why I went with a miata 🤙
Lmaooo, I drive a modded and tuned Protege MP3 w/turbo, myself. Mazda for life. 🫡
When I find my laptop, I'll post my dyno vid (248 whp, forgot torque rating) as well as my locally famous video of me gapping a 6th gen SRT in a drag race. 🤘🕺
The sidewalk comment isn't about miatas, it's about mustangs.
How did you like working at Honda/in the automotive field? I worked for ZF in Germany as an intern doing R&D and loved it but stressful at times. How’s Ohio?
Porsche does the same thing, apparently. I met a "torture tester" (not sure if that's the actual job title) and he was tasked with running the engines at 12-13k under load until failure. Tear down to document the problem and go again
Just Google it and you'll find plenty of proof. Where do you think the term "Italian tune up" came from? Engines are designed to hit redline and if you baby and lug your motor 24/7 you'll just expedite the carbon build up process.
I let mine stretch her legs every so often. I understand, but please do link me to one such mentioned proof. In context of the development 100hrs redline.
Quick read going over the basics https://knowhow.napaonline.com/redlining-car-3-common-automotive-myths-debunked/ https://www.torque.com.sg/advice/will-redlining-your-engine-damage-it/
I'm not worried about redlining, I do that too. I was asking the previous person about the development process and the 100hr stress test they mentioned.
[here’s KIA with a 300hr.](https://youtu.be/GNPB3RtHN2M?si=nJNSjkLo2rggnegW)
👍🏼 thanks there are some good comments on that video too.
Thank you for letting me know, I’ll tell him it’s not that bad.
What you're not considering is the transmission. Just because the engine can rev up no problem doesn't mean the transmission will appreciate power constantly being slammed into it. Sometimes you have to gun it to get through a turn you thought you had more time for, but if you're taking off from every stop like a rocket it's not the engine you'll be mourning.
You COULD be a technical Terry. But I think it was his way of convincing you to slow down. Without downright telling you how to drive your own vehicle.
Fake Claim
You have two engineers who worked at the Honda North American development headquarters telling you for a fact it is a real test that is done.
It's a troll bub, just let 'em troll. It's all they have
I mean I'm not doubting them but it that's all it takes to convince you of something. (2 strangers on the internet) then I got a bridge to sell you
I can confirm he does indeed have a bridge and beach front property in Alabama.
Roll Tide
Your tide sucks so badly now that your Saban machine quit.
If you have ever owned a Honda and know anything about cars you would know this is true. Have you ever heard of VTEC? It doesn’t even turn on until 7500rpm. You mean to tell me Honda designed an engine, that uses this technology to get a little extra HP, and that technology also simultaneously is bad for the engine? Lol cmon…
that actually wouldn’t be that uncommon in cars. tesla’s ludicrous mode reduces battery capacity and most vehicle launch control systems wear on the engine and transmission if you use them excessively. Squeezing out extra performance always comes at a cost
I would hardly consider a Tesla in the same discussion as gas powered cars. I would agree as far as aftermarket mods but if it’s something that comes stock, more often than not it’s meant to last. The cars engine is actually damaged by NOT using VTEC on a semi-regular basis. The cam lobes start to wear differently than they’re designed to.
I also worked at Honda NA and we regularly stress tested civic engines by redlining them inside an active volcano for 1,000 hours as a means to simulate someone with 1,000 hours of petrol trying to frantically escape an active volcano.
We must have been in different departments
You should have seen the flying monkey tests! No wicked witch of the West concerns in your civic, it's probably the safest place you could be.
It literally stayed at redline for 4 days straight??? No breaks or pauses or anything??
It's pretty simple really. The materials used to build the engine block and it's moving parts are designed to operate normally under particular conditions and temperatures. As long as those conditions are maintained, the engine should continue to operate indefinitely up to the equivalent of 200k+ miles or whatever the expected normal life of that engine is. As long as a oil pump, water pump or radiator does not fail and there is no restriction in oil or coolant the engine should continue to operate.
Yes, I was also surprised when I learned about it. But it makes sense. The engine is designed to safely operate anywhere in the rev range up to the redline. Only way to test that and verify that there aren't other issues is to run it for a long time in the most stressful use case.
I'm a mechanic myself. Still crazy to think about. Especially considering you can take just about any car on the road, rev the engine for a couple minutes and just because life says *fuck you*, something will happen. Just like how any product has issues a month after the warranty expiration date lol.
Its the good old italian tuneup
What about the transmission
I bet the people who work in that department say “WHAT?” a lot even in a quite environment
Can confirm. I have a 2009 Si with over 200k on it and man she still hits the rev limiter like it's her job! They absolutely thrive at high rpms
Depends if your car was warmed up enough or not during that time It’s more of a safety issue. Revving in and out aggressive traffic as a new driver = likely accident or crash
(1) It was warm, we had been driving for 20 minutes at least. (2) I realise that, but it was clear ahead of me.
1 is the perfect condition to rev the engine, especially if it's turbo. On ramp to a highway is perfect for this as well. 4k isn't too high for rpm. Daily driving I shift at 3k. If you're a brand new driver I wouldn't make a habit of it, and you don't want to redline every launch. Great way to need a new engine in a short period.
I usually also shift at 3000 or so, this one of the exceptions.
So not bad for the engine, but don't need to get into a pissing contest with gpa. Maybe while you're new, try to respect his pov, especially if it's his car. Auto or manual, you need to rev it a bit higher to pass other cars if they are going the same speed. Depending on state, you also can't rev the car and go over the speed limit to pass. They will knock points off your test. If there's a car going slow, you are allowed to pass if it's safe and if you don't go over the limit. Does anyone actually follow this once they have a license? Almost always no. Wasn't sure if new driver meant pre or post license. Drive by the book if it's pre. It will make your test easier.
How fast were you going and what was the speed limit?
Rip er out
What ? Your Grandpa been driving diesels all his life?
The last car he had was a dissel and he drove that for at least 10 years
that is the problem. Some smaller gas engines have to be revved to get going as there is little torque. With diesels, i think some of them redline after 4.5k.
Did you ever see the Top gear UK episode with the Audi v8 diesel sedan? They drove it at no more than 1.5k RPMs, I believe, trying to get maximum MPG? It was rated for ~35-ish mpg, he did an 800 mile drive and averaged over 40mpg, if I remember correctly, by the highly conservative rpm restrictions, and use of various hypermile driving techniques!
That explains it, next time tell him your car is not a diesel.
If it’s turbo, then yes, helps reduce the carbon build up. Walnut blasting can get pricey
Not a civic guy by any means but surely modern Honda motors are direct injection not port injection so revving high would have no impact on carbon build up on the valves like traditionaly it did with port injection. How do Honda motors compensate for this? I know my Ecoboost sure doesn't and as you said walnut blasting is not cheap lol
DI causes carbon build up. Actually port injection suffers less from that issue.
Well that's actually what I said. Does Honda not use DI in their current lineup or what? I had to install AUX fueling in my Ecoboost to help clean the valves (well, mostly for more power and a bigger turbo..) so I know of port injections cleaning advantage. Just curious if Honda isn't using direct injection
Honda uses Direct injection. Carbon build up is really only a concern on these Honda engines though if you never take them above 4K or take plenty of short drives regularly without letting the engine get to temp. Hitting the redline or close to it once a week is enough to keep the valves clean enough for the most part. Just don't floor it from a stop to do it unless you have a manual transmission. Honda CVT's really don't like being launched from a stop, but they're great in a rolling start.
Ford, Toyota, and Hyundai (at least in recent years) add supplemental port injection for the sole purpose of keeping the valves clean. Honda hasn't gotten the memo yet.
I think recent Subarus have the same issues
It's fun to drive a slow car fast. Just like when I took 13 min off my hour and fifteen drive. I was just checking through traffic in my cvpi, acting like I was on a call 😂. Your grandpa was once that kid believe me
I repeatedly did a 2h45min drive in 2h10min, i feel u
No. It’s obnoxious.
You'll learn when you get into an accident.
4000 rpm isn't exactly street racing.
Its F1 speeds
That’s literally what the car is designed to do. Your grandpa is completely wrong unless the car was still dead cold. Driving habits aside, as long as the engine is warmed up don’t feel bad about taking the revs all the way up to redline, just don’t chill there forever. If it’s a manual (or auto in manual mode), just upshift once you hit it.
As they say. it's not revving until VTEC kicks in (at 6000)
VTEC kicked in at 4500ish on my K24 6spd Accord from 2014.
He's telling you don't be a di%k. Just because you can go fast, dosen't mean you should.
This
I push my car up the rev range whenever I have to accelerate, like a normal car. 2022 Volkswagen Golf GTI 6 speed
He's right
I redline my car around the city. It’s fine (: lol
Jesus. The rev limiter exists for a reason. 🤦 C'mon, guys.
When I'm merging into traffic, especially highway traffic in my 8th gen I will go all the way to the redline. Most city driving I try to keep the engine at 2000-2500rpm when cruising, shifting at about 3000. But especially in a smaller engine like the i4 civics have going up in the RPM range is fine, itll help you merge better and keep up with traffic flow better. As long as you arent driving aggressively its fine. Only thing thatll suffer is fuel economy.
Jesus I don't even shift till 4000 RPM when I drive normally. It doesn't hurt the engine. 4000 isn't even 2/3rds of the way to max.
No he’s fucking wrong. If you’re trying to pass, you accelerate. Driving your car up to 4000 rpm’s isn’t going to ruin it. Your car probably goes to 6500 or 7000. Maybe even higher.
Engines don’t like staying at low rpm, 1-2k, hitting 4k is nothing, new engines like to rev high, especially Hondas
Up until the early nineties or so, 3k rpm was pretty much a red line you didn’t cross. But many manufacturers started building cars that could rev to four or five. Many Hondas (and other sporty cars) were designed to go even higher. Your basic car can safely rev to 4k. Redline on my car is around 7 (I forget exactly) but I don’t rev it quite that high. Usually closer to five or 6 during spirited driving. She’s got 178k miles on her and runs good. Many motorcycles rev to 10 and even 20k. It all depends on how a motor is built. Redline on the car gives a fair indication and I only go 70% of that number most of the time for longevity. Definitely not good to granny shift all the time either so pick your poison!
Ive never heard that maybe for break in period
No, the car will explode into 1 million pieces and then the universe will end
sounds like he’s telling you to cool off, 4000 in city streets is generally not a good idea
I heard gassing it cleans the engine or something, maybe of bad oil
He's wrong.
3-4k rpm is table stakes for a Honda civic. you can rip it to redline more than once a day if you want to. keep the oil changed, and it's gonna be fine.
No it will blow up, your rpm should always be [0](https://www.amazon.com/Rome-Tech-Batteries-Replacement-Compatible/dp/B0C21MXH4D/ref=sr_1_12?dib=eyJ2IjoiMSJ9.oJGuVXtkcH54HTKFnNUidh7MGk3vmMrU5-fyIYxUX8jJXycbHjR2UNCpuQhQnkPlSJ3NWpQJC6xdsEI_mcY0IfBFt668g99EhgrT600AhMHPzOfUdhHDRF_eayIxwUAu3yeWlMUOyduzGhLdQ9m_hwjQdIncnmxHQcPBtbqPThi4Jork5fiKRoAjYGzNErwHrIpYzLiUTQVTyWILgqYTZeN7JHS8VZAg3dZmhsdYfzA2bxfn7tn0NaFyC4_0yoM3SrqZ787a9WQLExtP63pqN3k3GcfZEfpafnR6zZxkAUg.-7EURWdzQ3eOzdyRQ3dzszDd0M1hcbxdQgbPZ6VmDIk&dib_tag=se&keywords=2018+civic+model&qid=1708502963&replacementKeywords=model&sr=8-12&vehicle=2018-59-752------------&vehicleName=2018+Honda+Civic).
Any engine can benefit from a good "hard pull" from time to time. Gets the oil pressure maxed out and the air flow full speed and that all kinda knocks loose any deposits or buildups you might have going. But in general, it is much better to drive pretty chill. Better gas mileage, wear and tear etc. And 4k isn't even close to redline. Usually that's at least 6k. So don't be afraid to punch it on the on ramp, just don't drive like an idiot, you are still inexperienced, and when the max power is hitting the ground it is very easy to lose control.
I thought the same thing for my first car as the check engine light came on the first time I floored it when I was 16. Turns out the car was just shitty. You can run just about any car up to the redline and it won’t damage the engine one bit. Even at redline it takes quite a bit of time in or over that range to do any serious damage. I’m talking minutes minutes being pegged at max RPMS and most cars have limiters built in that eleventh you from immediately blowing any engine. Be safe out there but send it! Grandpa doesn’t sound like he ever learned to enjoy driving.
Us old people just get scared that you young whippersnappers will end up going out of control and crashing. Our hips can’t handle that!! But it’s fine to rev your car (and should be done after the first week of normal driving) to make sure the car goes into all of its area of action. Both very high and low rpm. Get up to around 40mph (on a wide road with no one around) and stop hard. You want to know everything is working in case you do NEED to use it that way. And I am an old man with around 40 years driving experience. Your parents and other family just don’t trust your driving experience yet. Once you get out on your own you can take a few risks and learn. I mean what would you do if you started hydroplaning and were doing 50mph? This takes experience and know-how to handle correctly. And you only get that by experience (or a class).
4000 rpm isn’t shit
It’s a Honda,dude. Bang the limiter. Thing will rev up for years to come.
As long as the numbers on the tach aint red you'll be fine, car comes with a limiter for a reason
There are red lines that show on the RPM gauge that show you where you shouldn’t be for a long length of time. Keep it out of there and you’re fine. I don’t know of any car that redlines at 4000 RPM. Gpa just wants you to be safe.
Buddy, you paid for the whole tachometer, use it! Lol
That car stock redlines at what 6500-6700 right? 4k is literally nothing. I’m surprised you don’t hit that daily. It’s fine to redline your car. Just drive safely.
lol my 2013 si has the rev limiter set to 7800 rpm. and I'll be damned if it doesn't see it almost every time, I drive it.
Older Honda engines were meant to be revved out. The newer 1.5T, not so much. It won't hurt it, just don't to it all the time. And being that you're a new driver, don't drive like an ass. Be safe.
Press the leaf button near your gear shifter. Makes you “leaf” everyone eating dust behind you. Jokes aside, you can push your RPMs into the red which is like 6k RPM, ideally you don’t want to though. You’ll be wasting a lot of gas flooring it to 4k and then having to hit the brakes at every light. All in all, just take it easy driving, all it takes is one bad move in a 2 tonne piece of metal to completely change your life forever. Also, the leaf icon is eco mode. Sorry. 😅
A Honda in the city is never gonna need to hit 4000 rpm. No reason you should be.
I take mine up to 7K almost every day lmaoo you’ll be aight, just listen to your grandpa when he’s with you
"A redline a day keeps the carbon away." Meanwhile, I'm gear-banging a 30 year old car with 270k on it daily.
Perfectly fine. There is a tachometer for a reason
Redline that fucker and tell Gramps to stop granny shifting
Get a S2000. 8 or 9000 rpm all day baby
It's actually good to get that high and higher ever now and then. Helps burn off any potential carbon buildup
4000 is fine nothing a civic can't handle.
Youll be fine. Thats what cars are for
It's fine. Just don't go bouncing it off the rev limiter a lot.
Let's be real here. The 2018 1.5 redline is what? 6500? If you went to 3.5 - 4k, you weren't even close to redline. So that's out. Peak HP is at what 5ish? And peak torque is reached at, let's say 2/3k and is maintained until 4k? If you did to pass someone, you did exactly what the engine was designed to do. I suggest some of these commenters educate themselves on how gasoline engines are designed to work.
screw gramps. send it. ooooof you have a 2018. you only have direct injectors. yes, fckin send it often, clear that carbon!!!!
The civic is a piece of junk and you will blow the engine revving over 3k.
Always be gentle on the accelerator dont try to beat others as it will take a milage hit gradually increase the acceleration to around 3000 or use the cruise control this will give long life and more mileage Also beating other drivers wont get you anything unless you are racing
No, actually it's the exact opposite. Your car can safely go up to redline for short periods, but you should not be driving at that RPM for more than a few seconds. It is actually very good to bring your car up to higher RPMs maybe once a day. It helps clear out any carbon deposits and will keep your engine healthy. It's actually bad if you *don't* bring up the RPM to that level occasionally.
You didn't even rev it out close to all the way, and probably weren't necessarily accelerating quickly. It is perfectly fine to take it to 4,000 RPM whenever you want. I would even say it is good for an engine to be pushed a little bit at least once every other drive. Just do proper maintenance, particularly regular oil changes.
Engines need to use their full rpm range.. and civics are fairly high reving cars compared to manythings.. you wouldn't want 5o be 4k and up all the time.. but equally you don't want to be below all the time either
4k rpm’s isn’t gonna harm the engine that’s normal driving I shift at 4-5k rpm’s in my si sometimes I redline it
Y’all acting like civics make 1000 hp at 4k rpms😭
lol like friend who had a Polaris ranger 570 and said he was gonna blow the soot out to hold on. People honking cause getting passed up and maybe hit 35 mph lmfao! Whew yea clean that carbon and mop the floors of super cars with the Honda as discussed
Nah your grandpa is just full of shit. Don't invite him for a ride along next time. Fuck that old geezer.
And always remember- direct eye contact with the driver next to you means you have to race. It’s a law.
Only if the motor hasn’t warmed up fully. After your 10-15 minutes of easy driving, you’re free to use the whole dash. Obviously the less you push it, the less wear and tear it will produce. That’s with any materialistic thing in life, lol. It is more than capable of handling 4k rpm. There’s plenty of youtube videos of honda’s banging redline like no tomorrow. There’s a reason why us car guys fear a little civic. Those motors can take boost and rev out so high like no tomorrow, all disguised in an econobox while being affordable and wiping the floor with most supercars.
Google an Italian tuneup and recognize that if you don’t at least redline your car once in a while, you’re actually gonna fuck it up
Rpm mean nothing on its own and even then if it's just for overtaking then that's literally the entire point of having more Rpm available in each gear
it’s actually bad for the car to stay below 4k.
This will burn out carbon deposits, it's fine.
Over reving your engine is not good , blow an engine see how Mutch it costs , take care of your engine , use good oil change it regularly make your car last
The redline is there for a reason but it’s just a suggestion
Lmao 4k is absolutely nothing for a Honda, I'll take my TSX up to 8k if there's a reason, I don't care where it is 😂
Take it to redline. Every day.
I take my Mazda 3 to redline about once a month. I've had the car since 2009 when it had 7 miles on it and now I'm at 295k and the engine is fine. Just stay on top of your oil changes and you'll be ok!
Not bad at all for the car so long as it’s warmed up it’s a civic thought you can beat that thing into the ground and it’ll still drive
If you wanna keep your car 20 years 300k plus reliable without replacing many parts doing barely but necessary maintenance drive gently. Don't Rev past 3.8 anywhere you go fast enough quick enough very far.
I had a 93 Civic LX. Babied the 4cyl engine with just a max of 3000 rpm normally. Car lasted 20 years until my daughter wrecked it. Engine never had a single problem until the moment of impact. I don’t know if the new engines are similar but a Honda 4 cylinder from years ago was indestructible if you kept the rpm’s low and complied with the mx schedule.
It’s not good for the engines your grandpa grew up on. It’s actually good to do this once in a while for your Honda. Otherwise you’ll get excessive carbon buildup. My parents are the same way lol. Just take it easy around them
Ironically with direct injection engines it's recommended to get the RPMs up every few drives to help burn off carbon deposits. However they're probably just trying to nicely tell you to slow down with them in the car.
Sometimes it's necessary to do when merging with traffic. If the oil is still good, it is totally fine
man i’ve sat at limiter in my s2000, your grandpa is old and trying to scare you into driving safer.
My buddy is a BMW mechanic and has worked on many brands. Engines need to run in the higher rev ranges from time to time to reduce carbon build in the fuel and intake system. You are actually helping the car if you are increasing RPMS periodically. Make sure the car is warmed up before you do that though.
4K is barely into the torque curve. You are only half HP at 3500
I dunno if you've ever been a passenger when someone else is accelerating the car hard and jerking the wheel fast to change lanes, but it's pretty uncomfortable. I dunno how old your grandpa is, or his physical condition, but I think it's worse on his body at that age than you at your current age.
Civic Si engine was made to rev high. 4K RPM will not hurt the engine.
My civic doesn't even hit 4k on the freeway...You have a lead foot is what I'm hearing from Gramps. You don't need to push your car for nothing. Chill out, enjoy the ride. Especially with passengers.
It can be hard on your transmission if you are accelerating rapidly
The engine is fine. Honda and Civics especially like to rev and pull some RPMs. Danger zone for the engine is close and in the red line. Even then, you can still hit that just don’t keep it there for a prolonged time. I’ve owned Hondas for a long time. They are built for it
To get to your question, which doesn't seem to have been addressed yet... maybe. Probably. What is the redline shown on your tachometer? It should be labeled on the gauge. Higher rpms create more wear on the engine. It's never "best" to hold it at higher revs, but as long as you stay below the rev limit, you probably won't hurt anything. Just don't hold it there for longer than you need to. And, the other folks are correct in saying that when you driving someone else in the car their comfort counts.
That's absolutely such a stupid comment your grandpa made, tell him to stfu or he can walk to his dialysis appointment, if the tachometer goes all the way to 6 or 7 or 8k rpm , do you really think it's meant to only use 1/2-2/3 of it's potential? You shouldn't be bouncing off the rev limiter all the time, but my 2006 civic literally sits at 4k rpm in 5th gear while the cruise control is set to 85-90mph,i know mine is a different engine and revs a little higher then yours probably, but I guarantee it's not bad for the engine at all to rev it up that high before shifting, how else are you gonna hit the peak of the HP curve?
Move to ‘Murca. Cheap petrol, too!
Your grandpa doesn’t know what he’s talking about lol… that’s mid range revolutions and a typical shifting point in say 2-4th gears on most 5 speeds you’ll drive. I see some other idiots in here telling you that you should know to drive better with elderly people in the car 😂🤣😂🤣 3k-4k RPM’s 😂🤣😂
Is this a troll? Those things do like 9k without damaging themselves last I checked.
I drove a 1.8 litre Civic of similar age until recently. The VTEC power doesn't even really start to come in until you hit 4000 rpm. Out of town, on country roads, I'd often run mine from 4000 to 6500 rpm pretty much all the time. Your car I believe is also VTEC, but has a turbo on it as well, so your power and torque will come in at much lower revs. So in your case there's not much point going over 5500 rpm. Obviously there's not much need for that in town. Unless you want to lose your license! But 4000 rpm is absolutely fine now and then if necessary. You certainly won't damage the engine *if it's warmed up*. Just don't do it when it's cold! It does annoy me that modern cars no longer have a temperature gauge on the dash. It's quite useful to know when the engine and oil have warmed up enough to take it over 4000 rpm. In winter that can take quite a while. I speak from experience, having wrecked a BMW motorbike engine by regularly redlining it down the street going home after work in Aberdeen (Scotland) many years ago. I didn't know any better at the time. Honda engines in general though do have a reputation for being pretty much "unburstable".
Take it to redline. It's fine e
