Is your car suffering from cold start damage? Learn the 5 CRITICAL mistakes that could be destroying your engine every morning.
As a professional mechanic, I'll show you exactly what happens inside your engine during cold starts and why these common habits are reducing your engine's lifespan by up to 25,000 miles.
A cold start occurs when your engine has been sitting for several hours and all components have cooled to ambient temperature. During this crucial period, your engine is most vulnerable to wear and damage. You'll discover why metal expansion, oil viscosity, and proper warm-up procedures are essential for engine longevity.
In this video, you'll learn:
1. Why revving a cold engine causes catastrophic damage to pistons and cylinder walls
2. The truth about idling your car to warm it up (and why it's harmful)
3. How cold oil affects engine wear and proper lubrication
4. The hidden dangers of short trips and quick engine shutdowns
5. Expert techniques to minimize engine wear during cold starts
Whether you drive a turbocharged vehicle or a naturally aspirated engine, these cold start mistakes apply to all modern cars. Understanding proper engine warm-up procedures can save you thousands in repairs and extend your engine's life significantly.
Want to protect your engine? Watch now to learn the correct cold start procedure and avoid these common mistakes that mechanics see destroying engines every day.

Living in a northern state (Wisconsin). I crank my vehicle over and warm it up for a few minutes only if I have to remove a copious amount of ice or snow from my windows and have no other option than to do so before traveling for safety reasons. On a regular day I start my vehicle and wait for the tachometer to drop a bit (usually 30 seconds to a minute) throw it in gear and drive slowly until it reaches a better operating temperature. Some solid tips from this video in my humble opinion!

Wisconsin has very cold winters with lots of snow and ice, so combine the times of snow and ice removal with a 1-2 minute idle time looks good to me... but not longer than that. If more time than that is needed, remove half of the ice and snow, start the engine, then do the other half.

I was an engine mechanic in a large dealership back when you could rebuild and repair practically the entire car. The veteran engine mechanic who had been there since 1950 said to me before he retired " the little old lady's car who only drove to church is the car you dont want to buy. For all of the reasons you stated in this video. Along with the proper recomnended viscosity also use quality name brand lubricants and if you live in the northern tier of the 48 states change your oil at half the recommended mileage. I have maintained my and my families vehicles for decades. Engine work is one thing we never had to do other than proper maintenace.

I would also add that oil temp is prob more important than coolant temp. Oil temp takes long to get to operating temperature than coolant temp does. In other words just because your coolant temp is at operating temperature doesn't mean that you oil temp is too. Unfortunately for most modern vehicles, the car doesn't let you see your oil temp. Just another way modern cars don't last long and are engineered to get you into another new car sooner. Money money money, the only thing that matters to some.

I told my wife that we need to park our cars in our garage. Even unheated, the garage temperature is 49-53 when outside is 30-35. And our cars don’t have cloudy light covers even after 15 years. Some of my neighbors, for a variety of reasons like their cars are leased, park outside. In the winter, it’s like refrigerating the cars which is 37 for my frig.

I had heard the opposite about idling car engines at cold start. The premise being what you mentioned about expansion rates of dissimilar metals and materials recommending it. Also the auto start feature on new cars is for that purpose. Especially in the winter months a car is usually started and allowed to warm up to circulate cold oil and clear windows using the climate controls. About the oil, I agree with temperature and viscosity being factors for oil grades, but another major factor is maintaining fuel efficiency which is why oil viscosity numbers and ISO grades have been reduced over the years.

Sorry for my bad english, im German. I try to explain it another Way. Its all about cooling. You know why a Nascar is able to drive 4 Hours Flat out at 8000rpm, and a F1 Car cant do this? Because of cooling. The cooling System of a Nascar is build this Large that it can handle 4 Hours 8000rpm. The cooling System in your Street Car is build to normal Driving in Traffic. If you start your Engine and let it run in Idle it never get Temperature. Maybe in the Summer it will get Temperature, but in the Winter? Forget it. You can run your Engine for 2h in Idle and it never get warm. All you do is putting exreme wear and stress on your Engine, while lettig it run for 10minutes while it is cold. Like in the Video sayed, try to get the Engine warm as fast as possible. To minimize Engine wear.

One of the things I did when I rebuilt my Tundra 4.7 to 5.0 engine was to use teflon skirt of Pistons. And I also added a pre-oiler that I took out of my old H 1 Hummer. When I start my truck up, the first position is accessory. It turns the pre-oiler for 30 seconds and then I start the engine up. I’ve also got this set up on my auto start. Basically I’ve programmed the auto start through a script file to turn on the pre-oiler for 30 seconds and then start the engine up

Sounds like most people commenting may live in southern California or Florida. I grew up in Northern Minnesota. 30-50 below 0 is not unheard of, and I've experienced 85 below 0 wind-chill...117 degrees below freezing. You could literally drive for 30 minutes and it would still be -20 to -50 inside your car, if you followed the idle for 30 seconds and go routine. Who wants to dress for an Antarctic expedition for their daily commute? A little off topic, but I currently live in Colorado and studded tires are legal here. Seems like they should be legal in every snowbelt state. I grew up in Duluth, Minnesota, picture a miniature San Francisco. Most of the city is built on a very steep hillside. People claim cars running studded tires cause alot of road damage. Semis cause 100,000 times the damages as a car with studded tires. A 40,000 - 80,000 pound truck literally crushes the road. Where do you think the grooves in highways come from?

Engine startup, no revs. After 30 seconds i start the driving. No full throttle until it has reached operating temp + 5 mins for the warm oil to reach the turbocharger. I never drive short trips with this car, every startup leads to a longer drive. After longer highway trips i let the car cool down in idle for 30 seconds. The Engine never needed a repair. it works like on day 1. Send this video to all of your family members. Everyone should drive like this.

I do everything you said! I always warm my 2005 Mitsubishi Colt Plus Ralliart - with the 4G15T engine - after start for 45 secs. Which I time on the stopwatch on my phone. Then I drive slowly away not going above 2000rpm until the temp gauge gets into mid range. Luckily I live atop a hill so I can part coast down. The only thing I've been bad for that you pointed out is driving the 75 seconds to the supermarket down the road, shutting down then shopping. Then starting again and coming home. I need to stop doing that! Must plan stops at the supermarket when the car is warm say on the way home from being out. If I've been away and been pushing my car I will let it idle down for 60 seconds to let turbo oil cool. I don't push it hard enoug to warrant getting a turbo-timer. She's a torquey thing my 4G15T. The Turbo starta sucking & blowing at 2600rpm. I can easily stay below that around town and easily keep up with traffic. Another fab watch sir. Happy New Year from Australia East Islands! Grayson

If you have a display with instant fuel use display. Start the car, wait idle until liters/km shows near your average value when car is fully warmed up AND when your rpm goes down to your average fully warmed up range. Example for a 1.6 turn 2019 c180 coupe would be less than 1l/km and rpm between 700-650rpm. Idle times are usually longer in winter if you cold start with ac or heater immedietly on (which is never recommended)

@HonestMechanicChannel, your correct to let it idle 30-60s first and on all your other points ! You as well as other U-tubers on this subject, never CONSIDER/mention THE 2 step engine preset FAST IDLE!! [fastest then a kickdown to FAST (then normal)]!! I normally wait for the 2nd kick-down before I take off; which by the way is your 30-60s (?maybe longer if 'really' cold?). I take it easy then [ keep between 2-3,000 or so (4k)rpm], till OIL temp. needle begins to move off peg. I THINK FROM NOW ON you incorporate /mention fast idle into your future comments on cold starting. {a GOOD question TO CONSIDER would be is driving off with idle on its fast idle cycle a good idea / i.e. hurt the engine???;;; also ,would most cars' fast idle cycle disengage and go to normal idle speed earlier than normal? / is this ok? !

when the engine is cold it will probably run rich because the O2 sensors aren’t ready so 60s idle is enough to warm then up at idle cars run at optimum air fuel ratio, however, long idle times can cool down the o2 sensors and then they may start to run richer. if they have heated sensors this should not happen

Hello. I have a 2016 bmw 218i active tourer with a 1.5 turbo 3 cylinder and a automatic transmission. When the engine is cold ( mostly in fall and winter time). And the engine is rev above 1000 RPM it’s not able to drive away. The car will simply not accelerate and go in second gear. I have to wait about. 40’seconds and than the meter is below 1000 RPM and than i can drive away without issues. Is this normal?

I've long wondered why ICE cars don't have a small oil reservoir after the filter and an electric motor to circulate that oil BEFORE starting the engine. Seems like a no-brainer with the minimal cost being recovered in MUCH longer engine life.

Your wrong warm up the engine with long idle then take off slow. Bad advice

you dont gotta be THAT gentle when its cold, just give it like 15 seconds runtime (idling or driving) and you should be fine to go to mid revs and wide open throttle. if your car has piston oil jets you can redline by the time you get to half warm coolant. the best way to keep your car on the road for as many miles as possible is maintenance all around, not just the engine.

Wrong. No such thing as excessive idling. Do not drive till engine heats up.

Modern cars last WAYlonger than they used to. What are you talking about? Back in the olden days we were lucky to get 50k miles out of a car!

You can crack an engine by running cold. iy is called thermal cracking.

Sir everything you said makes sense especially if you're driving American cars. But I drive Toyotas and had several of them over the years the mileage has been 168,000 too 417,000 with the oldest being a 1996 Camry. And every single one of them ran until I got rid of it. Just routine maintenance driving over 100 plus miles a day with cold starting and all the other stupid stuff you do behind the wheel. "JUST Saying" Toyota 👁️

Your piston reaches operating temperature in about 8 seconds, the engine block takes about 20 minutes...

If i am engineer i would develop electric oil pump with normal oil pump and for heating i would develop electric heater that warms coolant. AC compressor only freezes i would develop AC that heats and freezes. Develop VR8 cylinder engine (one head) that can work only with 4 cylinder for fuel consumtion. Timing with only gears. Supercharged engine belt driven or strong electric charger.

Rule of thumb I go by is whenever the cold high idle drops to below 1000rpms so the transmission goes into gear gently whether that be 30 second or a minute and half. The engine isn't the only thing I'm protecting. Different cars idle down at different speeds.
