🚨 THIS MAN WARNS: STOP WARMING UP YOUR CAR - YOU’RE ACTUALLY CAUSING ENGINE DAMAGE A mechanic says idling your car for 5–10 minutes like it’s 1995 is doing the opposite of what you think. Modern engines don’t need it. "Most cold-start engine wear happens because excess fuel washes... oil off the cylinder walls." When your engine is cold, the computer runs a rich fuel mixture - extra gasoline to stabilize combustion. That fuel acts like a solvent, washing oil off the cylinder walls. Less oil = piston rings scraping closer to metal. That’s where most cold-start engine wear happens. Idling keeps the engine cold longer. Driving gently warms the oil, transmission, and engine faster, ends the rich mixture sooner, and restores proper lubrication. The fix is simple: Start the car. Wait 15–30 seconds. Drive easy until temps rise. Long idling only makes sense for frost, fog, or extreme cold. How many people are quietly damaging their engine every single morning without realizing it?show more

This is completely false. Modern, computer- controlled engines, even back to the 90’s, only run a slightly rich mixture for about 15 seconds or so. Having warm oil, fully shaped pistons and proper warm clearances will result in less engine wear when you actually accelerate.

If oil is getting washed off your cylinder walls by fuel you have bigger problems in that your piston rings are shot.

Well what about when its freezing cold outside and you don't want to get into a ice cold vehicle. Plus when your windshield is covered in Ice?

This guy is a tard who doesn’t understand how temperatures work. Nobody starts the car and waits “for the engine to warm up” It’s, so the heater warms up you fat dummy. Also, all his moronic claims are debunked with regular oil changes.

Professional mechanics in cold climates say otherwise.😑

This dude is an idiot and needs to be banned! This is false information!!

I disagree, almost 331k on my 2015 Silverado with no engine issues other than new injectors.

The thermostat doesn't open up automatically

Idiots... people who say this will always say something stupid and half of you don't have a car with over 350k miles and it shows.. lol

You can test this yourself. Pull your valve covers off and start the car on a sub temp day. Watch how long it takes for oil to travel. It takes a bit. You can drive your car like that but its not lubricated like it would be if you warmed it up for 5 to 10 minutes.

With zero weight oil I want a minute or so warm up time to get the "worms" doing their thing to thicken the oil just a bit.

I only start right before I leave. HOWEVER, because of my hydraulics, I DO make sure to plug it in more often than not 💯 Especially up here in Canada 🇨🇦

Oh STFU. I warm the car so I don’t freeze my ass off for 10 minutes in the car.

How about older cars pre 2000

They want the car heat to be warm. They aren’t doing it for the engine.

I don't warm up my car to get the engine warm...i do it to warm up the inside before I get in and drive off!!!

Either way; when anyone says warm up the car, its for their own comfort/frost removal lol

@LoveBling6 It’s been about -25C to -30C here for the last week or so. I bet we are OK…

Most men should already know this.

Yeah sounds safe

Nigga, it’s cold as fuck where we live. 15 minute warmup mimimim.

A lot of this information is incorrect. Not to mention it’s good for your transmission…A vehicle’s transmission, particularly an automatic one, “warms up” primarily through the heating of its automatic transmission fluid (ATF). This fluid serves multiple roles: lubricating moving parts, cooling the system, and enabling hydraulic functions like gear shifting. When cold, ATF becomes thicker and more viscous, which can lead to sluggish performance, increased wear, or inefficient operation. Warming it up reduces viscosity to an optimal level for smooth functioning. The process is gradual and relies on heat generated from the engine and transmission itself.

@grok Is this true?

Why is gas washing off the oil inside your pistons? They should not be mixing. That means your rings are no good and your engine is toast

Start your car to warm the cab up or your gonna freeze 🥶 at -20 inside the car lol

This guy is a dumb ass when there’s ice on your windshield buddy. You have to run the car for 20 minutes before entering now your fuel injection system has nothing to do with that amount of ice.

Not really you need to warm it up a little bit to get the oil and everything flowing. Just don’t turn the heaters on till after 10 minutes.

Some retards still think it’s 1995, but wait… they want their butt warmed.

But my husband does

well can't see outside of the ice layer on my car so should i drive witht hat too

No worries, that's why they make new cars.

While the fuel is coming in at a richer mixture for warmup efficiency, think oil is being moved right back into the cylinder. Not warm thin oil, thick sticky stuff until it warms up. The fuel is going to have a hard time washing that off.

Then why did they make remote starts
