Scotty Kilmer hi i have a question the O/D light does not turn on when i put the O/D what can i do to fix it ,thank you
hey scott i noticed a bit of cheese stuff where the oil goes in but its not the head gasket thats away as the water levels are always the same maybe dampness from over night due to the cold weather ?
Scotty recording equipment cost more than Is cars.
Sorry but I always let my car run a few minutes before I drive it when it's cold out. I live in Pennsylvania and we get some cold winters and most people around here let their cars warm up before driving. You can do damage to an engine if the oil isn't circulating through the motor properly. I run 5w-20 in my Explorer because that's what the manual calls for
Scotty: Rev up your engines!
Scotty: This is why you shouldn't rev up your engines
Scotty: If you rev up your engines you’re stupid
Scotty is great. A lot of personality
lol
Lol
🤣🤣🤣
Watching this while my car warms up lol
Same. Sitting in my 2003 jeep....sigh
Same here lol
drby0788 lol same here bro 😂
Lol doing the same
Lol same, in my Lexus is300
It's not hard
Start it
Let it run for 30-45 seconds
Be *easy* on it till it hits temperature, then drive normally
Respect your car and it'll take care of you
My neighbor puts his car in gear a fraction of a second after the starter disengages. I guess he is late for work every day.
Lawrence Taylor or they have pther things to do other than sit in a car and waste time
it takes 5-10 minutes where i live in winter
Hahah Bro I aways leave my diesel to run for 3-4 minutes, during winter I leave it for 7-9 minutes or more 😂
I'll stick with Scott's advice but thanks for your uninformed opinion.
Sure you need to warm it to some degree . Sure oil will flow instantly, but it still takes around 5-10-20 seconds to lubricate everything normally. And I like to let my cars warm a minute or two before I get going . Nothing wrong will come out of it, that’s for sure .
Agree! When the RPM's are still high, I think engaging the transmission is not the best choice. I give a couple of munutes, especially in winter time.
I just start my car instantly then put the rear defroster on and step out again to remove ice or snow from the windows. By the time I’m back inside the car is about halfway warmed up and after 5 mins of gently driving it’s on operating temperature.
I totally agree. For years I've always allowed my cars to warm up then I got into this very same debate with him about whether it was necessary. I tried it his way and within less than a week I had to change my timing chain. Car engines endure so much so what's a few minutes or even half a minute for newer cars?
Depends on whether or not you’re merging onto a highway or climbing a hill shortly after cold start. I live in a quiet flat neighborhood so I don’t give my car more than 30 seconds before taking off.
@@surena9451 I do the same thing. It makes more sense to me than just sitting in my car and waiting for the defrosters.
In my experience, a transmission always works/shifts better when warmed up. I’ll stick with warming up for at least a minute and several minutes when it’s cold out.
If you can a mix of both schools of thought is good. Too long of cold idle to warm up is increasing wear time. Warm up driving where you keep it under 2500 rpm is probably the most ideal. In other words getting that temp up fast but safely.
Some cars have a thermometer on dash like mine and after 3-4 min idle it turns off and you can drive
@@Mytabernacleisinher you mean a temp gauge?
@@SpicyMcGeezak yes
Stupid. It takes about 20 minutes for the oil to get to temperature. Your also not considering everything like your tires or suspension all of which needs to be warmed up.
I warm my car up everyday. It sits all night sometimes 12 - 14 hours and in the winter 10 degrees at night or colder. Nothing will convince me it doesn’t run better after warming up first. Running it cold, you can almost feel it telling you to “give me a minute.”
Yeah I have an 18 year old car with a turbo and the noise and feel difference between running it cold and letting it warm up is night and day
Engine talks
LIKE HE SAID if you are in freezing conditions you need to warm it up so it can keep you warm and be able to defrost the windows NOT for engine protection
@@u-know-this you should still do it for engine protection. Give it at least 1-2 minutes to circulate the oil and get it to a temperature where it isn’t as thick and can move fast enough when under load/rpm
@@u-know-this I feel bad for your car
I personally treat my cars like I treat my women no matter the age.
I always warm them up a couple minutes before I go full throttle. 👍
Hugh Jass watch it.
(No matter the age?)
@@amypopov7726 houston, we got him.
Hugh Jass I’m gonna steal that when I get asked this question

@@amypopov7726 i see your point and yet have to say its something how a few words can haunt a person for life . now we have to wonder has that guy been a very very bad male or was it just some not so well chosen words.
I warm my car up just for the transmission's sake, not the oil or anything. You can feel her struggle when it's cold and she hasn't fully warmed up yet. Treat 'er gentle and she'll treat ya right too.
Me too.what car are you driving? Volvo V40 here
Both my cars do this where you have to go like 3,000 RPM and the car is only going 20 MPH I think this is built in function.
Yep, Ive noticed the cold-start struggle with my Subaru Impreza. Sounds like each car is different and you cant make blanket statements about what is good and what is not. A car owner with a brain with make the right intuitive adjustments to their particular cars unique character.
Uhhh… the engine doesn’t warm up the transmission, only using it will warm it up
@@George-uy2kb Im aware the engine doesn't warm up the transmission. I was saying, I don't warm up my car for the engine's sake: I warm it for the transmission. The transmission does warm up without using it. When I do a drain and fill on the tranny fluid, I watch the temp go from room temp to 108-120 F with my laser thermo
one more Red Bull would put this dude over the edge
Kevin Jones it doesn't have any affect on you when you're on coke, as I imagine.
Kevin Jones
Like the billy Mayes of the auto common sense world.
Lol
Lmaoo
Redbull doesn’t do this to me. This is called cocaine, brotha. Lmao😂
I warm up any combustion engine before use for one simple reason, metals all expand at different rates at different temps, slowly raising the temp is much better to keep things tolerances from becoming too tight under fast thermal expansion.
Exactly! It's not about fuel economy or how it runs, it's about extending the life of the engine and transmission!
Exactly right Michael! Thats the bottom line! Professional athletes don't run out onto the field and start exerting themselves immediately!
It’s 100% true in my eyes I’ll always let my engine warm up plus I drive older cars any ways
At bare minimum I let mine get some temperature in it, when it shows on the gauge thats when I usually start light driving. I wont go above a certain rpm until the engine is all the way warm. We've all had those mornings when we wake up and have to get to work fast lol.
@@kevinmitchell3168 all bull. I have a motorcycle with 880k on the clock and never warned it up. Start and go. Anything else is a waste
I like to warm up the engine quickly, just hold it on the rev limiter for two minutes before setting off.
I allways do that and then I powershift from standstill.
without using the clutch, just get that nice immediate engagement in the tranny.
I love the grinding noise the car makes everytime. It also serves a purpose. Because when you hear that, you know the gear is almost engaged.
I remember a guy in Toronto who liked to rev his engine from cold. One very frosty morning we heard a very loud bang, and his engine never reved again.
You guys have got it all wrong, fucking amatuers.. The trick is to put the car into first and have your accelerator pedal to the floor before turning the car on. Noobs
For an engine with higher mileage especially in cold weather the lubrication works better with warmer temperature. You can hear the engine sound changes and gets smoother when warmer so if i would push the RPM higher than idle too soon with less lubrication, it will definitely cause more friction and wear. Also transmission fluid when warm will circulate more efficiently leading to better pressure and shifting with less slippage which will eventually effect clutches lifespan in automatic transmission.
No need to push RPM high, just start and drive normally to warm engine up faster.
Scotty turned me on to proper transmission care. And my transmission sounds and works much better when warm. I am surprised he gives this advice, and only speaks of the air/fuel ratio
@@miste.remusic I was surprised too.
No matter if its a Rolls Royce or a VW Beetle - all engines are bound to the same laws of physics. Engines are all made of metal, and metal expands and shrinks depending on the temperature. No matter what advanced computers or fuel system you have, it cannot prevent excessive friction and wear when the engine is cold. And even if you have apropriate low temperature oil, its still best to wait for your engine to warm up abit, unless you want to do engine rebuilds frequently.
@@miste.remusic @2:44
Engines are designed to run at a specific temp. Too cold or too hot not good. Warming up your engine also warms up your automatic transmission.
Also help reach the right temperature for the right viscosity the oil is design to run at. Do 6k rpms on a car you startes 3sec ago... You'll probably have a bad time
M series will tell you max RPMs for the engine temperature.
Does manual transmissions exist in america ?
@yerb Unless your engine, transmission, and power steering pump are made to pump air not oil, you should just chill and let it warm up before driving off.
I agree specially if you want to keep the piston rings expand to keep the oil away from the explosion chambers.
"Warm up your engines!"
Always
I’ll warm up my feet for my bike
Today im gonna show you why its not a good idea to warm up your engines
I don’t care what the temperature is. I will always let any engine, brand new or not, light or thick oil, carbureted or injected, warm up for a few minutes. Gives me a piece of mind I guess.
Scotty contridects himself with this vid. Dohc engines and other complicated valve train engines need time for oil flow. Some parts heat faster than others under cold load. Oil temp is key and it is the slowest come up. Many road track racers recomend multi waight/ blended from a few drops in to 50 differaint waights. Makes the oil handle like a 0w 20w in cold yet gives the higher melecuilare density of the higher waight oil (Hydrocarbon polomer chains). Thin oil drains away the thick oil stays. The thinner oil moves the thicker into place and absorbs heat from the thicker oil that stays in the metal matrix. Manufactuars want every one to buy a new car. So they desighn obsolecance. This is the best way they do it. Engine oil. Make it wear out slowly so uneducated on auto ownership pays more. Yet we all can do are own research. Felt like putting in a few cents
Gabriel Bray Me Too 😂 Gotta See That Temp Needle In The First Line 😂😂
i always let it warm up for 3 minutes, and than drive away and switch gears at 2100rpm until its full warmed up.
I always let the engine warm up until the thermostat opens before driving. It worked 50 years ago and although it may not be necessary today, it can't hurt.
Gabriel Bray Same. TBH, I have a theory that small things like this are why some people's car go beyond 100k mi and others go to a scrap heap
The purpose of warming up an engine is so you don't put too much stress on it from temperature differentials. If there is a huge difference in temperature between the inside and outside of the engine, this will create a lot of internal stresses since the inside will expand. But if you allow it to warm up slowly, there'll be a smaller heat differential and fewer internal stresses. This will make your engine last longer, and your less likely to have thing start to break.
NAILED IT MR
Yeah man
Yes and no. It’s good for it to slowly warm up. But that doesn’t necessarily mean at idle. You should let your vehicle run for like 15-45 second’s depending on how cold it is. Before you drive. This is usually how long it takes for it to idle down. As long as you don’t rev it really high after that it’s fine. It’s better to drive it not long after you started it because this allows it to warm up quicker which will decrease the amount of time that it’s running with thicker oil. This doesn’t mean drive it normally right off the bat. You should drive it slowly at the start so that it’s not too hard on the engine
Step dad taught me this young and I'm greatful
Hell yeah Scotty doesn't know crap
idk man. lmao... i have a 2009 mercedes e class and i notice a huge difference if i start it up cold and drive, as opposed to start up wait 2-3 minutes and drive.
if i drive cold, my transmission wont shift into the next gear until it goes into a way higher rpm and it shifts jerky. but if i let it sit 2-3 minutes, it shifts like normal
Probably a transmission issue, not an engine issue. If where you live makes it possible, you can creep along the street at a slower speed. The engine and transmission will warm up faster.
Then again, there are different kinds of cold. Where I live now, the coldest morning you will ever see is in the 20's and the 30's (F) is more common. Back in Chicago, it could be 0 (F) or even colder in the morning now and then. In Minnesota or Canada, it could be very cold every day in the dead of winter. I would let an engine warm up at least some before I started driving. I would want to think that the engine oil was at least as warm as it would be on 30 degree morning before I started moving. That's 0 C, more or less.
Marks Tech that’s normal it prevents lugging when engine isn’t at operating temp. My 2001 tacoma does this. It will not shifts into the next gear until I hit about 3k rpms
@Drew McCarthy You have to know whether it was made to work that way before you can declare its behavior normal. I don't know and I am sure you don't either. Unless you have definitive information better to present your ideas as speculation because that is what they are. If I had any issue like that, I definitely would research it.
My 96 e320 does the same
fpineros22 If you can afford a benz why buy a toyota? Id only buy a toyota if my budget was too tight to get anything more exciting.
I live in Minnesota, I’m warming my engine. Oil is like honey at minus anything, and if it gets real cold you transmission won’t shift right.
@@MidwestRainstorms transmission fluid uses a radiator that runs with the antifreeze so as the engine warms up the transmission fluid is as well
Krahnik89 oh yes sir it does and my man is exactly correct that’s why I let my little civic warm up on the winter time it shifts hard if I just let it warm up for a min it if it sits 10 mins shift smoothly so somehow it warms up kinda like this guy said with the antifreeze
I warm it up because I have to drive it, and I like to have warm hands
@@MidwestRainstorms I live in Wisconsin. Do you know how cold -25 F (-31.7 C) is? You'll get frostbite just from touching the steering wheel! You'll have FREEZING cold air blowing in your face. Within 5 minutes, your lips will be like sandpaper! They'll be bleeding before you get to work! So take it from someone who was born and raised here, Floridaman, warming up your engine has VERY LITTLE to do with the mechanical components of your car, and has entirely to do with personal comfort!
@@MidwestRainstorms to check my transmission fluid in my cts I need to lift my car up and make it level then let it run for 3min to warm up 'transmissions fluids" then put the car into every gear for 2 seconds then back into park to let fluid flow into all parts evenly and only then can I get a accurate reading on the levels where I take a plug bolt out as if I'm changing oil (not regular oil drain plug)while the car is running and if it slowly leaks out it's at a good level, if not its low...it has no dipstick because some dipshit said we dont need it and put it into a sealed box(slot of new cars are being made lile this today). Anyhow this step by step is done by Cadillac mechanics and if they need to 'warm' up the transmission fluid for a good reading and it's done mostly with only idle I have a sneaking suspicion that it actually does warm up the transmission fluid.
Probably worth mentioning that you should drive the engine easy (compared to normal) until it's at normal operating temp, though. For various reasons.
I’d love to know the various reasons! 😅
@@asificam1 I have exactly the same opinion👍
And in simpler terms , cold metal on metal contact is harsh and causes excess wear and tear. drive slowly when the car is just starting its trip , but about a mile or 2 later you should be fine
Here is a general tip you can use.
When the car run it idle pretty high, when the car RPM goes down to something close to normal it means you can now move the car but it doesn't mean you can push it yet, when it reaches its optimum temperature only then you can push the car.
By pushing i mean try not to full throttle or generally stay under 3k RPM.
No false. Especially in colds in can take 10-15 min for the initial rpm’s to settle into 800-900.. this doesn’t mean you can’t drive until that point. Wait a min and that’s that.
@@ty8473 it doesn't make any sense what your saying. So your saying that because in some places the weather is too cold that a car takes 10min for the rpm to idle at low rpm so why not just idle for a min and your good to go? Doesn't that mean because the weather in some countries are soo hot you turn it on 5sec and boom your ready to go?
In contrary because its cold you should keep it idle for longer. A car was built to operate at specific temperatures.
EX-DAMN-ACTLY!!! Neuro!!!
This is the best advice! I've had muscle cars my entire life, and I always let the idle come down before I put it in drive and never do pulls until it's at operating temperature. Think of it this way, would you do a 25-meter sprint as hard as possible without warming up or stretching? Chances are you wouldn't.
If you don’t let the idle come down it is hard on U joints in your drive shaft
I always warm up my engine.

Hehe, living in Finland when it might be -30 degees celcius... We don't warm engines by starting it but we have external electronic or fuel powered heaters that warm the engine before start-up...

Not on a hot summer day, but when it’s -10 to -40 degrees celsius, your darn right I do.
You sad, thirsty man.

Correct procedure: Idle for ~30 seconds, then try not to exceed 3k rpm until its up to operating temp.
Joe Barbaro i do 2min for -5°c or -10°c and below -10°c i use block heater and so on

Warm up you car for about 2-3 minutes, then gently drive and warm to the working temperature while moving. Definitely this works if your distance is long, not short.
unnecessary. you only need to warm it to operating temp if you are racing at high RPM's.
@@conn3r81 you have to be child, so you’re saying if you’re not gonna be racing you should just turn the car on and drive right off ?
@@buzzlightyear2851 he just probably doesn’t understand‘operating temperature{

Imma gonna fakkin slappa you
letting it run idle increases the amount of time your engine is running with cold oil which means it wears your engine out more than driving of slowly and driving with max 2500-3000 rpm.
Sorry, but I'm old school I still warm up my engines 3 to 4 minutes before putting in drive. Metals need to expand and lubricate properly before being put under stress.
John D I u r not alone, bro! Greetings from Ukraine
True. The idea that you don't have to warm up your car was probably started by auto manufacturers to sell their ultra-new technology to lazy people who are too stupid to realize when something goes wrong with their car anyway.
There is a thing I call 'mechanical empathy'. Where you not only know, but feel what's good or bad for your car.
I give my '03 Explorer 1 minute of idle (that's how long it takes revs to come down) and then drive it gently for 2-3 minutes.
I can FEEL by its response that it doesn't want to be pushed any harder up 'til then.
@@BWater-yq3jx Same here. I warm engine for 2 to 3 minutes, then drive slow under 20 miles an hour for about 1 mile or so. I'm not on a busy street , so traffic is not a problem. I can tell when the vehicle is ready to get up to speed. I like to keep my cars as long as possible. Not pushing or abusing them helps.
Same here brother. Being a machinist/ mechanic, everything I've experienced tells me it's better to do so and definitely won't hurt

After getting 300,000+ miles without a rebuild out of the original engines in my personal cars, and seeing "cold driving" wear on several thousand customer's engines during rebuilds....
I'm going to continue to WARM UP cold engines before driving away.
MIKE MOTORCITY OG Amen my White brother
330k on mine depends what kinda mood I'm in if I idle +1 min
Meh depends on temp. If it's above 32F a warm up is pointless. You get a warm up as you back out or pull into traffic. 15-30 secs is adequate. Oil pressure should come up within 1 second. You figure everything is lubed in less than 2 secs. Just don't ream on the gas for a few minutes on a cold engine.
If it's below 32F warm up the car. If there's no snow or ice to clear off, 30sec-1min is good enough.
If it's below like 10F warm up for 2 mins or however long you feel like. Usually at this temp I end up warming up for about 5 mins because I have to melt the snow and ice off the windows.
These people "warming up" during the summer are just wasting gas. Also no need for a warm up if the engine is already hot even a little.
Now a days All these You tubers are trying to be different. It’s always better to warm up the engine. The difference in newer and older cars is: older cars take longer to warm up and newer ones take less. This guy doesn’t know anything. I bet you when he never never revs his own Card hard when it’s cold.
The people that are defending this video are probably the same people that get out of work when its 0 Fahrenheit and get on the highway within a minute of starting the engine and just red line it up to speed. Yes you should warm up your cars people even just a few mins. Anything below freezing just give it a minute
This dudes awesome he’s just yelling at the camera the entire time
I dont give a too many shits about cars. Is he Aleins?
Omg
Lmao
He always does. Lol. Animated as it gets.
One of the reasons why I keep watching
Remember: It was the EPA (not engineers) who said you don't need to warm up your engine--it was in the name of saving gas. They don't care if you kill your vehicle prematurely. The various metals still need to be at their optimal dimensions.
I've never had a problem not warming up the car first. I just start it and drive normally without limiting the RPM. Our winters rarely get below freezing anyway. Modern engines already have the right tolerances and with thin oils, I don't see a problem.
Same pigs that sait start and stop sistem is a good thing
If it's cold I do let the engine warm up a little. I do it mainly because oil works better the hotter it gets.
Either way, I think the bigger issue is not putting too much load on the piston rings before the oil reaches optimal temperature.
As long as you don’t floor it soon as you start driving you’ll have no problems
@@BadDriversOfNapa modern engines do run tighter tolerances, making warm up much quicker. But they still need some warm up. They don't have some kind of magic metal that defies the laws of physics and basic metallurgy. The moving parts still have some expansion and contraction.
In a newer video, Scotty says, yes, warm up your car before you drive because driving a cold automatic transmissions does a lot of damage to the automatic transmission
Should I warm up the car, or should I just drive away while not accelerating quickly or going fast?
"When I was young, we didn't have automatic transmissions.We had to push in a pedal called a clutch everytime we wanted to get moving or shift gears!"
@@dumymariposa6795 Pretty sure it's only Americans that can't drive manual
@@hatchingdraggon8073 Some of them, anyway!
Which video?
Love the Channel, I learn a lot from Scotty. But I’m old school when it comes to my car. I always let it warm up for about 3-5 min. And in my case I come from a race car family that specializes in drag racing with Toyota four-cylinder engines like the 2RZ, 3tc and the mr2 motor. And we always dropped turbos on our cars. And the one thing I was always taught by my father was to always let the car warm up so the piston rings seal because if you don’t depending on how much boost you’re pushing you can easily blow the piston rings and blow your motor up. And in my case I drive a Volvo with the 2.5 turbo so I always have a habit of letting it warm up so that way the piston rings don’t blow up. That’s just me, everyone is different and has there own opinion and I respect that.
Even with a new car, I let it warm up for a few seconds until the rpm drop. Just makes sense.
That's the key... you wait at least until the fast idle stops and it slows down to normal idle speed.
Really? I hold the gas pedal down, ignition on, then drop the clutch.
xD
Yes I wait until RPMs drop low and stabilized
It's called common sense, yet it isn't all that common unfortunately
my neighbor never warms up his engine in the morning . he just starts the car and leaves. 3 days ago his car broke down for the 5th time.
I have not warmed up my car for 9 years. I just gave it to my brother and it has 0 issues.
@@vinnytucks87 I never warm it up either (except for the winter time when I have to scratch off the ice anyway), but I avoid high engines speeds before it has warmed up.
is that related. i mean. he also never had sex before goint to work so therefor not having sex ruins your car?
Theres no need to let it warm up for extended periods of time, however starting the engine and letting it idle for 30-45 seconds just to get everything circulating isn't a bad idea.
got a boss at work with a 2012 camaro, he starts and in an instant no hesitation he reverses and drives off no time waited. lately his camero has been sounding like crap, a rattler now.
Wait for the temperature guage to move up, and the rpms to stabilize. That will forever be my guide. Pushing a cold engine always makes me nervous inside.
Be aware that idling our modern car for too long had a negative impact on our engine because of premature combustion. Also idling your vehicle releases harmful chemicals, gases, and other toxins into the air. Vehicles manufactured post-1980 have fuel management systems designed to heat up the engine fairly quickly. Under normal wintertime circumstances, idling your car or truck for about 30 seconds is all it takes to get the engine above 40 degrees; ideal for typical operation.

@MKMW C ?
For me, the key to longer engine life is driving slowly/easily until complete engine warmup, keeping the RPM's as low as possible. I SUSPECT that some, if not all, engines circulate the oil better under load.
Or should you.....”Rev up your engines!!!!”
Thats funny....but don't do that
No , but I hear my neighbor do it allot when its cold n freezing .
Bryan Oliver well if he sells that car don't buy it
Dan Sebastian hooah
No, you can drive right away, but don't rev hard until the engine is all the way warm.
I'll warm up my engine until the day I die.
Amen metal's are metals I don't give 2 shits how well the fuel metering systems work metals need to expand to their operating temperature state to get optimal life out of them. Nuff Said!!!
@@skylerhouston It's hard to say what puts less wear:
- Cold idling(~3 times slower to warm up)
- Light load short shifting (faster but more load)
@@She1lby I've wondered about that myself for a long while. I met in the middle and with my powerstroke with 15w-40 I let it warm up for about a minute or two and drive it gently until oil temperature crests 140 then I drive normally from there. Doesn't matter the time of year to me, usually in winter it idles a little longer just cause I have to get snow off it before I drive.
Same.
@@avernon2778 Doing almost the same, i'm letting coolant temp reach ~55 C ( temp gauge starts to move ) that's about 2 minutes of idle, then driving it gently.
Would really love to know how engine load affects this though.
However, I notice a huge difference in the performance of my older transmission in a 2007 Mazda 6 when I let its fluids get a little warmed by proximity to the engine warming up with an idle for a few minutes in cool or cold weather. Obviously the transmission fluid can't get very warm without beginning to move the gears, but the aforementioned makes a noticeable difference.
Might just need a service with the right grade of lubricating oil.
True, that's why we need to get our car moving slowly, without revving the engine of course. Our car will warm up faster when moving slowly.
In Minnesota you want your car to warm up so the defrost works when you are ready to drive,especially in really cold weather.
I don't wait for my car to reach operating temp, I do wait for the RPM's to drop below 1k though before putting it in gear.
GrAYvTrAnE the way to go! Most righteous approach
Always a good practice no matter the temperature.
💯
Exactly , I believe this is more appropriate than warm up.. I do follow the same whether I start in Texas or Minnesota, I wait for RPM to go down below
GrAYvTrAnE If the rpm is stable after cold start. I think It’s warmed up already. Because the oil circulates well. I live in a tropical weather country we dont have winter but I can warm up my engine within 2-3 minutes during cold weather about 20-25°C outside temp on 5 o’clock in the morning
While he’s not wrong here, it’s not all about the air fuel ratio. Metal expands when it heats up. Engineers design the tolerances inside an engine with this in mind, which is why cars are set to run within a specific temperature range. Putting a hard load on your motor before it’s warmed up can lead to premature wearing of your engine’s internals.
Exactly!
What I learned is warm up for 2 or 3 minutes then start driving normaly. Idling too long can cause piston rings wear out
To my own experiences, the car 's engine would perform better, run more smoothly if you allow it warm up for 30 second to 1 minute in cold weather. I don't want to say Scotty is wrong or right but I will do what I think it makes sense.
I noticed that
Especially with diesels
@nguoiviet4023, well I warm up my vehicle up to 15 to 20mins before I drive, I turn the ignition and crank it and let the truck idle while I'm scraping the ice and clearing the snow ❄️🌨️, and have my hot coffee and light up my menthol cigarette by the time I'm done the vehicle is already warmed up and go to drive.
I set fire to my engine to warm it up. Work a every time.
LoL
I read this comment and bursted out laughing people are looking at me like I'm crazy ..... Best comment on the post 😂😂😂😂😂😂😂
I worked in auto manufacturing for years and I finally found something to disagree with Scotty on. Modern vehicles are built to very close tolerances and are designed to operate optimally at a certain temperatures or run temp. It is not as important as it once was, or does it take as long, but I have seen many a transmission valve body fail in cold temps. Also, as engines age, oil seals begin to fail and where oil once was retained it may drain out and it is prudent to wait for oil to circulate. Scotty you are great, but here I disagree.
Flores e xoticas
Yeah I think the guy above you isn't in limp mode
the most important thing is to read your car's manual on my car it says it's not necessary to let the car warm up just run it for 30 seconds after you start and you can drive.
That is a question I was about to make. I mean, engine is supposedly ok, but what about my automatic transmission?
I drive a Renault Megane II, 07. How long is it ok to leave it at idle before taking of? I'm in a 10 level subterranean parking lot, so I have to go up right afternoon take off. What do you guys recommend?
That guy at the top of this comment thread said he's in boner mode lol
I disagree. All vehicles, no matter how new, idle a little faster when cold. It only takes a couple of minutes, if that for the engine to reach operating temp, before the idle settles. Leave a little early, warm the car properly, and the engine will last longer, provided its maintained properly. Seen too many engines die an early death listening to this myth.
Efrem Williams I completely agree...regular oil changes and a tad of respect when cold goes a hell of a long way
@Old & New Video Mix , cylinder temperature has nothing to do with operating temperature.
It's pretty easy to tell when it's fully warmed up at least in my car because Auto heat won't come on until the engine is happy. But I believe in just driving slow anyway. Warm it up before you race up any on ramps.
when its -20 outside and you fire up your engine theres a massive difference in temperature. Pistons will heat up very quickly and unevenly while the outer cylinder walls are still cold. Cold starts as it is produce the most wear and tear on your engine. Best tp fire your car up, let it warm up for a minute or two and drive easy for the first few minutes of the drive
I have a LPG car which needs to run on petrol while cold. It will switch to LPG if coolant temperature has reached to 40 degrees celsius. In cold weather it can take up to 6-7 minutes when idle. When driving it would take some 2-3 km ride before it switches to LPG. Overall petrol consumption is less when i let it warm up at idle.
This is why there is a spec called piston ring gap.
@@NiiOnLood they just refuse to start on LPG when cold :/
Thanks indeed Mr.Sam Ya
If you read the owners manual it will say the same thing, wait 30 seconds then drive gently until operating temperature is reached. This ensures the engine warms up quickly without stress, and wear and tear on internal components is minimized.
Good point!
That is for liability reasons only, unless you talk about a really old car.
Manuals say that because it looks good to say no waiting, it's not really what is best for the vehicle. Just like 0-20 oil really is't the best viscosity but it helped them reach their MPG goal.
Warm up your vehicles folks...old /new whatever. Components need to expand properly and normalize due to heat..especially since in your engine and engine bay has a lot of dissimilar metals that will expand at different rates.
No need to warm up, just go easy at first
exactly. just drive at near idle speed for a few mins, then take it up a notch.
The engineers that built the cars say how to treat them in the manual. Read that instead, imo.
On extremely cold days(far into negative temps) letting components warm and expand a bit before stressing them makes sense. So is driving slowly for a bit, letting wheel bearings, cv's, and everything else that moves and expands settle into itself.
My LS1 engine has forged pistons that sound like a diesel engine on start up. Once the engine warms up the pistons expand, and the noise goes away.
I always run it until the RPM drops below 1k... at the very least there's less of a jolt when I put it in drive.
Been in the auto repair game for 22 years now. I tell people if it’s 90 out, more than likely all you need is to wait 30 seconds for the oil to flow, but if it’s upstate NY winter weather it’s just a good practice to let it warm up for a few minutes.
I warm mine up just to try and warm the gear oil in the transmission and same on an automatic and this is winter in Michigan
Thanks. You posted what i had in mind. The transmission in my car doesn' like it driving right away. Even putting stress on brake system .
of course you warm up your car... you're supposed to
If the transmission isn't moving then it isn't really warming, most of the heat will come from the engine and it will have a residual warm
Michael w of course man that's what everyone was talking about. But if you're sitting in your car you could also put it in drive while you're sitting there waiting on it to warm up and the transmission will start spinning the pump and putting a load on it which will further Aid in the warming up of the transmission
Tommy Hallum; MY FRIEND ... YES...
BUT EVEN THAT LOAD IS BEING PLACED ON IT COLD.
I still prefer to see the temp gage start moving before I set off ( or enter bottom of normal range) and then drive gently till its at least half way to the middle position.
tellucas atleast? Lol your fan not working?
LEXUS-RX300 he meant halfway to the middle position, mine also stays at the exact middle and never moves when its fully warmed up and i have a toyota corolla 2015 s model, i also do the same to be honest

@@Wolfz77 it's not good
Don't Push Me what’s not good?
Scotty, sensors can't beat basic metallurgy. So it's best to warm up the engine!
For all us current apartment dwellers, I'm sure you can relate.
My new 23' Taco has to sit out in the North-Eastern Winter 😥.
I let it warm up for like 5-10 mins any day its cold, just for the ability to have heat on my way to work since its only a 5 mile drive and ~4.5 miles of that is a 55MPH highway, and the on-ramp for that highway is literally the exit of my apartment complex.
There is maybe 1000 feet of driving between me and the highway, and I don't like the idea of highway merging/acceleration and speeds while its still ice cold.
But I'm not sure if idling for extended times actually causes buildup/any other issues or,
if idling even helps to warm the Auto Trans fluid which is probably the bigger concern with little driving distance before the highway.
@Jason Martinez Wow that's crazy, I've the 4x2 4 cylinder for economical purposes ie. lower msrp, higher miles per gallon!
I only haul a single dirtbike in the bed, no need for more power as I don't plan on actually towing anything anytime soon.
Gonna treat her right, and hopefully this little 2.7L 4cylinder will last me forever!
Just waxed and ceramic coated it today and man does that Barcelona Metallic Red really pop! (Lunar rock woulda been cool but not available on the SR, womp womp).
One thing I noticed with these engines is the injector cleaning noise shortly after startup. I usually use that as my “warmup” indicator and take off keeping it under 3k rpm until normal temp
Also I think at 55mph you should mostly be under 3k rpm besides the on ramp lol
@@karlwithak1835it doesn’t seem like you know what you’re talking about

+Kyle Conger thanks👍
This is not solid info.
Depending on temp i usually let my cars warm up briefly, but its the transmission that really likes to be warm!
Same. I don't know how it is in all cars but I know if I put the car in neutral it will engage the transmission and circulate ATF while the car is still idling, getting everything lubricated. At least that's what I was told.... and I haven't had transmission problems in my car since I bought it
NO NO NO! I still warm up my car for at least 30 seconds before I drive off regardless of temperature, and then I'm easy on it until it reaches operating temperature. Warming up for 10 minutes? you'll do more harm than good. But 30 seconds is almost a necessity. It's ESPECIALLY important on an older, high mileage car where the clearances are greater and the bearings are wearing out- you're going to want to give your oil a chance to thoroughly lubricate every part of the engine before you drive away. Do you NEED to do it, no. But SHOULD you do it, YES! Unless, you know, you don't care about your engine and want to wear it out faster. Most wear occurs on cold startups, not driving around. And woe betide the driver who floors it on a cold engine. You heartless bastards, you.
Totally agree.... this is the right way to warm up an engine and everyone needs to realize this. None of this "dont warm up ur engine!11" crap
My neighbor down the street used to rev the shit out of his V6 mustang ( he thought it was hot shit, we're talking SN95 V6, not a newer one!) Because he thought it warmed up faster....He wasn't laughing when it threw a rod, his engine seized from the oil spilling all over the road, and he needed a new engine at 58,000 miles! Meanwhile, my chevy Malibu DD has 315,000 miles on the 3.1 V6 and still keeps chugging. My secret? Warm it up for 30 seconds, don't run it above 2K rPM or 35 MPH while cold, regular 5,000 mile oil changes with synthetic oil and a little Marvel Mystery oil in the oil and gas every other oil change.
Yeah ok, get back to me when multiple cars you've owned car have over 300,000 miles on it and still run like new. 30-60 seconds is plenty of time to get oil well distributed throughout the engine. Any longer than that isn't really necessary. You also forget to mention the part where I said go EASY on the engine during the first few miles until it gets fully up to operating temp. You want to insult me, fine, but have an actual argument instead of being a troll.
If your boosted (turbo) and it’s 20 degrees out by all means let it warm up for a minute and then nothing over 2k rpms. My car has a oil pressure gauge and when it’s cold that thing is way up there almost 60 psi which is max. Takes about 5 miles then the oil warms and the pressure drops. I can only imagine if someone just got in and took off what would happen with that much oil pressure.
If it's that cold out, then it may not be a bad thing, but here in the sunny southland, it hardly ever gets chilly but for a few weeks a year. Many people warm up not necessarily for their engine's sake, but rather, for their own comfort. Just remember idling TOO MUCH can be bad for an engine too. Idling for extended periods is hard on any engine. All of my cars have good low-end torque figures, so I can still have plenty of power at low RPMs. The Malibu is my daily beater, but I also have an older Mustang Cobra (1999) and a 1964 Oldsmobile 88. I warm up all of them. Most cars i've owned have lasted over 200K, the longest lasting being a Plymouth Valiant slant six I had back in the 80s that had 435,000 original miles on it, and a 1988 F150 with the 300 I6 with 545,000 miles, and a 2002 Town Car with 336,000 miles. All still going strong when i sold them. The Stang has 120K, and the Olds reads 88,000 miles ( though the odo has probably rolled over a couple times during that car's time. I rebuilt it several years ago, put 60K on it over the last 8 years)

@@slothypunk give 5 minutes minimum of normal driving before you floor it. 15 minutes to be on the safe end
I give mine 1 mnt at least.
I always warm my car up for 10-15 min on average. It's a mustang. So before I get on it, I also make sure all temps have reached operating level. It's not to just allow the oil to circulate and lubricate everything because that happens very fast. It's more because it gives things an opportunity to gradually reach operating temp and allows things to expand. So even after warming up, I still won't go WOT for a few miles of driving.
I always let my car warm up. It drives smoothly.
Ikr!!

Has nothing to fuel metering when its cold. Cars have all different metals in them (piston, head, block, wrist pin, valves, etc) and they all expand at different rates. 100-150 degrees F from abient to operatimg temp is a decent sized difference for aluminum, steel, chrome, and brass to all work together. I'll ALWAYS let my vehicles idle to get every thing moving and at least 100*f of engine temp
hsvkidusa finally someone smart in the comments
It would be better to wait for atleast 30 seconds to let the oil start to flow through the whole system then drive lightly until it's to operating temp
skidmark: thanks for all the unnecessary pollution, dipstick.
You'll cause more damage to the engine by letting it idle especially in the cold. Gasoline is a solvent as its idling it will be dissolving the oil film off the cylinder walls and since it's cold the oil can't flow as well so your cylinder walls will get fucked over time. Driving lightly until it's to operating temp will let the engine heat up faster since idling doesn't generate much heat at all and the oil will heat up quicker keeping that protection.
I only let my truck idle for 30 seconds before driving a 97 ford ranger and it hasn't had any type of issues from it since I drive it lightly until its to operating temp. If your car uses very thick oil you should be changing to a lighter oil in the winter anyway that's that an issue. Letting it idle will strip that protective layer of oil on the cylinder walls causing more stress because it wont be lubricated like I've said and you have. Idling a fuel injected car isn't a good idea what so ever.
Just trust Scotty, he redlines his customers BMWs while it's dead cold.

@@slothypunk cool! I will try it on my e39 today
I live in Houston as well. It can be 100 degrees but I still let my trucks warm up. Especially my Chevy, the transmission shifts terrible until it reaches operating temperature. It can not be good for metal parts to be rubbing against each other when it is cold. Just because the modern fuel systems can handle a cold start easier, does not mean the internal metal components can.
I have a twin turbo engine. It needs to warm up some before driving for a few reasons. Turbos make lots of heat and it makes it quick. I don’t want to shock them too much as it can lessen their overall lifespan. Two, it idles high in open loop and makes it harder to slow down. I also like the transmission to warm up some before driving. I have a Ford 10R80 and it’s a fantastic transmission but it doesn’t like being cold. First shift is stiff and 3-4 slips. Been like that from brand new but only when it’s cold. After warming a couple minutes it won’t do this.
Cocaines a fucking hell of a drug
We had -65°F here in Mn. Warming up your car before driving is no myth here

Yep lol I grew up in Embarrass MN. You can literally break an engine by not warming it up in that. (Also why I moved out southwest lmao)
I Hear you, I'm next door in Wisconsin.
What a mechanic told me, the oil takes a while to spread through the entire engine because it is all at the bottom. So let the engine idle for a while before driving away.
It takes around 30 seconds for oil to flow through all the engine. If it takes much longer, it means you have the wrong weight of oil in your engine
You still have to wait 30 seconds then.
@@zonedout5998 yeah, but some do it more than a minute without knowing they are damaging their car more while idling. By letting our car sit to warm up, it’s actually putting extra fuel into the combustion chamber, which can get onto your cylinder walls. Because gasoline is an excellent solvent, too much on your cylinder walls can dissolve the oil that lubricates your cylinders, leading to shorter life on crucial components.

Warm up your engines.
The owner's manual says I should.
When I start my truck in cold weather the last thing on my mind is "I wonder if my engine is firing at the optimal air/fuel ratio yet". I'm thinking mostly about oil temp / lubrication and differential thermal expansion of the many many moving parts in the engine that were made with tight tolerances.
Don't you think manuals would say to warm the engine for 7 minutes if that were necessary?
@@h.d.h I could be wrong, it probably isn't necessary to warm up your engine as much as I do, that's just my preference based on how I think about machines. But to answer your question, no, owners manuals don't list all the driving and operating techniques that will help your car last longer.
@@jessequentin4441 An owners manual usually does say not to drive the engine too hard when cold, but it never does say to idle the engine till it's warm.
Its necessary - modern car manuals will tell you to get going immediately, cuz modern car manufacturers put priority on the eco-norms, and not how long your car will last. Infact they would like it if you ruin your engine, and have to buy a new car. THE FACT IS you need to wait for your engine to warm up no matter if you're driving a 2022 or a 1922 car - ALL ENGINES ARE MADE OF METAL and are bound to the same laws of physics! No computer or fuel system prevents excessive friction or wear if you start running your car without waiting atleast 30 seconds for your oil to start lubricating. Your cylinders and pistons expand when your engine warms up, so running your engine cold is a very bad idea - thats when the most wear happens. Thats exactly why Taxi cars do higher mileage than any other car - cuz their engines are always warm. So yeah, you need to wait atleast 5 minutes if its like 0 or less degrees outside. Doesnt matter if you're driving a Rolls Royce or a VW Beetle - you're gonna ruin your engine if you drive it cold, even at slow RPM. Wait atleast till your temp gauge goes atleast abit up, dont need to wait it to completely warm up.
You should have maybe pointed out though, that it's better to not high rev until the engine is warm ;)
yogioto this. It’s not about the oil as much as the metal itself
First thing Scotty says is rev up your engines
Considering how oil needs to get around the entire engine for it to not rub metal on metal, I choose to wait
Do you have an idea it’s done at the moment you finish cranking your engine?
@@ShuotongLi depends on the oil and temp. I have a 2008 Passat 3.2L V6 with 270 bhp, on the day i bought this car i went home and directly made an oil change though it was changed only 3 months before. It was Castrol 10W40 LongLife and it was already black like tar. On that day it was -3C cold and i only let the car sit for about 30 min after arriving to gather the tools. Believe me, this 10W40 was far away from "flowing" though the motor was still warm. Since then i have changed to Mobil 1 NewLife 0w40 Oil in all my cars. Especially in the passat it looks after 10K Km almost like new! Even the 0w40 is more like greasy honey when at around 0 C... It will never reach every place just by a few cranks from the starter.
@@bogeydope3022 You were lied to about the last oil change.
@@dr2377 By whom? Myself? I always did those jobs myself, unfortunately the previous owners of my cars did not and paid a fortune on shitty long life oil by castrol.
Besides im a toolmaker and fairly into lubrication and the surfaces involving. I can see it with my own eyes how different oil behaves at temperatures and the corresponding mileage in my engines. That maybe won't work for all engines but at least for my VR6 3.6L FSI Passat. Since i used 0w40 mobil1 fs0 that engines just runs fine, zero oil usage and that stuff looks like shiny golden honey after 15k KM on the Road.
The first time i used 10w40 castrol edge and after 10k KM it looked like a tar sludge, engine had a lot of failures in cache because of the constant carbon build up. I could go on and on about that topic, worked at Porsche Zuffenhausen and they also swear on mobil1 0w40 fs0.
@@bogeydope3022 the problem wasn't the brand of oil. It was the weight. Cold temperature and the passat had 10w40 in it??? It literally had the wrong weight of oil for the wrong climate. 5w30 would've been fine or 5w40 which both are recommend by VW.
On a high performance car, you have to let the engine run up to operating temperature before pushing the car.
certain performance tuning softwares will not let you the turbos create lots of boost (power) to protect the engine and its components.
Tuning software such as JB4 for BMW does this, as a protective feature.
If bmw made this softwares so troubles will be comes 😂😂
Man this channel has come a long way. Great to see it grow.
shutup kid
2019 RAV4, always, warm up my car. So, the engine and transmission are properly lubricated, as well for proper thermal expansion.
I always let my car idle for about 20 seconds in the summer and about a minute in the winter just to be safe.
Thats the right amount of warm up needed.
@@skrillah6259 Not true, today's car are engineered to run from cold without needing to idle. This is because of huge advances in material science, lubrication and manufacturing technologies.
@@a.alphbond9003 Yes but people are stubborn, and a lot of people don't have new cars.
@@skrillah6259 It's extemely important to follow the manufacturer's maintenance recommendations if you want your car to last longer. Assuming a recommendation for cars of a generation is better and applicable to cars of another generation is erroneous.
@@a.alphbond9003 Warming up a car is not maintenance, what you are saying is that warming a car up for a minute instead of just driving of will hurt it. You ain't making any sense.
Safest way is after starting engine, let the car idle untill its Rpm gauge reads its lowest "normal" idling rpm. Now you are safe to go because the engine oil is now sufficintly circulated and engine is stabilized, but you have to drive gently at first since the engine temp gage at this time is still far from its normal operating temp. You drive it gently at low rpm untill the temp gauge settles to its normal driving temp level, then you are safe to Rev up your engine!
P.s; warming at still untill the "engine temp gage" settles to normal temp is too much waste of fuel and is totally umnecessary. It is more economical and enviromental friendly to just drive gently at lower rpm untill the engine temp gauge eventually reach its normal temp gage value. This info is explained in my car user manual (volvo MY15)
Agreed 🏎🚙🏍🤙🏽👍🏽
Give the s54 and s85 sum respekt.
That's prettt much what I do.
Gasoline is cheap but engines are expensive. Just let the Vulva warm up dudette
Agree but warming up till the temperature gauge is at operating temperature will give you 70k miles before rebuild i guess
