My 2016 car go up to 1500 for a minute then idle at 800 rpm, you can tell the difference when a car is warmed up vs one that is not. A friend of mine used to drive off inmediately and broke the car, her mechanics told her to let the car warm up before driving, always warm up your cars guys.

So your telling when it's -27 outside in winter I shouldn't warm it up?
Kiryu Kazuma (3 дня назад)
Well where I live is almost 30 or 20 and sometimes 15 F so yeah I have to let it warm up a little bit
TaSoScRaZyMaD (3 дня назад)
You are just wrong.. Any engine has metals and valves that expand when they heat up to have a perfect fit. So if you dont want to have the valve seats to settle you should warm up your engine
Sadiq Muwakkill (3 дня назад)
Wow! Great video. I believed this myth until today. Great explanation also. Keep up the good work!

Car parts are like body parts it's the same principle as stretching before you workout. You can work out all you want wo stretching. Some time later you'll be experiencing increasing joint pain. Don't cars have joints in them? Drive ya car soon as you start it up and in some time watch ya engine turn into the incredible hulk😂

Scotty I'm new to your channel. Ever since I bought a used '99 Subaru Forester, about 2 weeks ago. I scrolled up to the search bar on YouTube in hopes of gaining more knowledge about how to buy a used car, tips and suggestions etc. Found your channel. Good to go ! After watching this one, I realized you also live in Houston. Can I bring my car to your shop, and you use it for a video ?.

When I was a kid, my dad had a 1965 Ford wagon with a 352. I remember it had a blue dash light that came on after start up, that said "Cold". Back then that was a great idea, considering it was a four bbl carb with choke, and the oil was probably straight 30 weight.
Juan Orrit (6 дней назад)
I would not call It Warming it UP. But at least Let the oil flow UP to the heads and all the Engine.
Justin Hunt (7 дней назад)
Why is there nothing said about the stress that it puts on your belts and any belt driven components when you drive your vehicle cold? You only covered and 50% of the reason mechanics recommend warming you car up.

Even car manual says start driving car soon as possible. so iam whit scotty on this, this does not mean that you should beat it before it gets normal temperature.
hazim bobob (9 дней назад)
My lancer GT when i start the engine and it's cold the R.P.M reaches 2, and it's 2016 model so it's modern car, is it normal? later after that it goes below 1 after warm up, seeing the Toyota matrix warm up between 1-2 makes me surprised.
Stuart McLean (9 дней назад)
Yeah winter where I live is like -30 to -50 at that point everything gets brittle so I'll keep letting my car warm up. In fact Poursche does winter testing here and I've seen them warm up their cars, so you go ahead and tell the Porsche engineers that they dont know the best things for their engines....
Robert Nocera Jr (9 дней назад)
I always want to warm up the engine when the temperature is below 50 .. however if you have a manual clutch you should always warm up first, definitely with motorcycles.... thanks anyway scotto.
2001FLHr (3 дня назад)
Robert Nocera Jr At last somebody knows something. I have been riding motorcycles for 53 years, Farmall tractors, Ford 9N, and trucks and cars with standard transmissions. You can tell the difference in cold and warm engines pretty fast. I now drive my 2010 4Runner Trail and with the automatic transmission. I can get driving faster on those zero or minus degree mornings. I still start the engine and put it in drive almost immediately with foot on the brake then drive away slowly after a half minute to full minute. Remember he said something about common sense also. I am sure Scotty takes a few seconds to check gages. All these old guys do that.
FifthGear (9 дней назад)
I always let my car idle for 1-2 minutes before driving off, then drive it very slowly 1300-1800rpm until it gets to operating temperature. It takes my 1996 Mercedes C200 Kompressor about 3 kilometers of slow driving to get up to 80C in ice cold weather.
Gregg Collins (9 дней назад)
when I learned to drive the trick was to only let it warm up to the point where the engine would rev without stumbling. Not very long at all. Usually by the time I had the windshield scrapped it was ready to go. That was a 67 Cortina w/ manual choke.
Suai Bochosuta (9 дней назад)
you don't necessarily need to let it warm up to operating temperature but it's good practice to let it run for 10 or 15 seconds minimum to allow the oil to circulate through the system
joe gladue (10 дней назад)
I like to warm up my truck when it's -16 out for 10mins
Fj40365 (10 дней назад)
Hey Scotty , I have a classic truck that I don’t drive very often, once or twice per amount. what are your thoughts on block heaters? Will this improve the oil life of my engine and will my engine benefit from being warm all year round?
Ryan McGregor (10 дней назад)
Scotty, should I buy a Mazda CX-5 AWD or a Toyota Rav-4 AWD? Which car will last longer?

you should warm up your car in cold weather
Derrick Zenner (11 дней назад)
Completely agree
Layput (11 дней назад)
Scotty has no idea about what he's talking about.
Layput (11 дней назад)
Scotty is talking about fuel injectors. The issue of warming up has to do more about oil circulation, lubrication, oil viscosity, and shaft abrasion. This is misinformation at its best. When it comes to fluid mechanics, don't trust a mechanic.
Layput (11 дней назад)
Warm up your Engine.
HBterreur (11 дней назад)
Thanks for the info Scotty👍🏿
Derek Likos (11 дней назад)
I always wait for my car to get to normal idle no matter the temperature outside( around 750 rpm when parked) then I take off. Never look at the temp gauge though. Unless it’s really cold.
Zac Zoidis (11 дней назад)
I remember in VT I let my 4th gen LGT warm up for 10 minutes every morning before commute :. )
Ali Elzein (11 дней назад)
What about cracking the engine block on a cold drive
LRoy Shreding (12 дней назад)
Its not the Engine its the Transmission ! I notice most new cars don't accelerate 0-60 as fast when their cold. The car will Struggle when getting on a freeway .Some cases doubling the 0-60 time.
Ryan Scarington (12 дней назад)
This dudes awesome he’s just yelling at the camera the entire time
Derek D (12 дней назад)
But I do live where it is often anywhere from -20 average, to -40 extreme but common in the winter. I use 0-20 in my 2018 honda, as per manufacturer recommendation. I let it run for about 1-2 minutes just until the rpm drops from about 2k to 1k. I also keep it below 3k rpm until warmed up. Have alsays done this with my vehicles and never had any trouble. Common sense. The warm up debate really depends on where you live. But even then I agree you don't really have to warm them up a ton, just dont give'er until warm. We also need to use block heaters and plug-in our cars in the winter.
KOB. MMIII. (12 дней назад)
What u do is turn the car on and immediately red line it for 20min and power shift. If u don’t it right u should hear a grind in the transmission 👍🏻👍🏻👍🏻 np people

You don't have to warm the engine, but you should anyway. It's a good habit, especially in cold weather

Hello there scotty, My car have a noise inside my engine because i didnt yet change the engine oil can it be fixed? Thank you so much
egotripband (13 дней назад)
i always warm my car up before driving off . that and regular oil changes keep it running sweetly . .
Ravishankar K (14 дней назад)
when i start my car it revvs automatically to 2000 rpm and then aftersome time 40-80 secs or so it comes down to normal idling of 700-800 rpm. my car is suzuki ignis new car dec 2018 model. so warming up is essential.

Yeah it doesn’t matter. I drove as soon as I started up my turbo diesel bt50 for years with no issue.

I used to live in MN, try firing up a car in January and see what it's like to run without giving it 5 minutes to warm up the oil.

Check the owners manual!!!
Francisco Garfias (15 дней назад)
Myth not busted. What about pistons and rings , bearings and oil viscosity. All those tolerances change with temperature. Warm oil flows different than cold oil. Only fuel system was explained.

Incin3ration (16 дней назад)
As someone with 284,000 original miles on my car, I agree that you don't need to warm up your car before you start driving. However, I think you should have added to drive and accelerate lightly until the engine is at full operating temperature. My personal rule of thumb is to keep the engine speed below 3000 RPM's until warmed up. Hammering on a cold engine is not good!
Z (16 дней назад)
I second this guy's oppinion on this. True, engines barley need warming up. However, on VW Jettas MK4 and up including DSG, the transmission needs to be warmed up by the flowing coolant so the valve body can pick up preassure so the gears shift smoothly as there are precission trans. So, no Scotty you are wrong on this one.
Shane995 (16 дней назад)
yes you can start and drive cold engine. but don't go full throttle or very high RPMS
mario alvarez (16 дней назад)
Lmaooo to all these comments...Scotty must be ripping patches of hair of his head😂👴
adam bennett (16 дней назад)
you're engine will have oil pressure in about 3 seconds flat. once you have oil pressure this means oil is going to all areas of your engine (you dont have a dry engine until its at operating temp) so its not truly necessary. HOWEVER if you want to start driving your car hard (red line etc) it is a good idea to get your oil to operating temp as the oil will be thinner and flow more easily to various areas and you need oil there ready to lube and cool otherwise the rapid expanding of metal on metal will cause issues and oil will not be accessing these areas quickly enough.

I thought it was always a good idea to let the seals have a chance to warm up so they don't leak oil or fluid ?

Not everyone uses 0w-**w oil however. Those with 5w-30w (for example) should give it a few minutes still!

naseem hany (16 дней назад)
Logically there is no need for any engine warm up. Do you need to warm up your home AC or washing machine before using them? No matter how much time you spend to warm the car engine up, a lot of mechanical parts in the car will remain cold and will not benefit from the engine's heat while the car is stand still, actual driving will warm them up.

Scotty is that ur Triumph?

That Lebron hairline though
youcanfoolmeonce (17 дней назад)
Scotty has good taste; he rides a Triumph! But I warm up my engine for a minute even in Southern California. I never had an engine failure in 45 years.
Floyd Bailey (17 дней назад)
You want to warm up your engine some so the components can get lubricated with oil. Would you drive something that is metal on metal? Doesn't sound too good, does it
xLoganx Wolverine (17 дней назад)
Would you drink tea when it's hot or cold? Because I would believe you want to warm up lol

I always warm my gti before school for 15 minutes, that gets it up to its temp. Then after school, while everyone starts up their car, shove it in reverse and just go. While i let start my car, put it in neutrel aand just let it idle for 5 minutes
2.0 Lyf Pop (17 дней назад)
I drive a turbo charged car. As my 1st turbo car I read you should let the engine warm up and noticed it runs a lot smoother. If I drive off on a cold engine and day I notice it hesitates changing gears. Keep in mind I drive a 2018 car bought it brand new with now 10k miles.
Assaad Helou (18 дней назад)
When the rpm is down you can drive even in New car it's better to warm up

stan8t8gt (19 дней назад)
BULLSHIT!!!!! All these saps want to talk about efficiency during warm up instead of the real issue which is wear on the internal engine components. The colder the ambient temps the greater the need for some warm up time! If it's a 80 degree summer day just drive it like a granny until it warms up. This will lesson the wear on your internal engine components and extend the life of your engine. Don't doubt me!!
gary B (19 дней назад)
unless there was ice on the windows, I never did let my car warm up. Never ever had any problems with my cars. My neighbors let theirs warm up 15 to 20 mins.

O.P. Yates (18 дней назад)
that being said 15 to 20 minutes is ridiculous.
O.P. Yates (18 дней назад)
Maybe YOU didn't have problems with it but how about the poor people you sold your cars to. Ever get 250,000 to 300,000 miles out of one of your cars?
Greg Hakes (19 дней назад)
I see mostly Women taking off without warm up, most Men are smart enough to let their cars warm up before driving them. Women have that mentality that if they start it up and drive it they will get heat in the car faster. While that maybe true their pre wearing their engine parts and causing extra wear on the Transmission that will cost uka bucks down the road.
