How many of us go outside and start your car in really frigid weather, like we are going through now, and let it sit idling to warm it up. It can damage your engine by doing this. I googled a good read about the dangers of warming up your "gasoline engine" in super frigid weather, Especially if it was made after 1980. Prior to 1980 cars had carburetors, new cars are fuel injected and this makes the difference. The article says it's best to get in your newer car, start it, buckle up, and drive off. Lubricants do there thing while the car is moving!! , not while it's sitting in your driveway. The circulation of lubricants in cars with carburetors are different.
So, scrap off the frost/ice from your w/s..mirrors,etc., buckle up, and drive your newer car off and let it warm up. You have an EV ? Different story. I encourage you to google this info..might just learn something like I did. I think I'll go get one of those w/s covers so ice doesn't build up on it. I'll do that after the freeze!! Stay safe and Merry Christmas to all. BTW...I don't know how to post a link so help me out there.

Written by an environmental wacko.

Did it mention to allow idle to bring the oil temperature up enough to boil the moisture out?

So unless you jump in it and take off.... A long enough distance for the oil to heat up. Your engine is going to have a lot of moisture internally.


And engines with a carb or fuel injection. Have the exact same oil pump. People had to warm up their car so the carb would get hot. Helping the fuel atomize. Fuel injection sprays it already atomized. Therefore, better cold weather performance.

Google just doesn't want you idling your ride. Climate change hysteria.

this ^ ^ ^ ^, at idle your oil pressure in a newer vehicle should be around 40 psi and going up from there.

carbs had to heat for the choke to quit choking and making the mixture rich enough to run cold. computer takes care of that now.

heck, I paid to add remote start to the f150 just so I don't have to drive off freezing.

My neighbor, before we moved up here, thought the article was a B********** one! He said just go buy a heated Dipstick. I thought he was giving me the horn but there is such a thing. I don't get out much!!

you are better off with a block heater that goes in one of the freeze plug holes, it heats the whole engine through the anti freeze.

used them in colorado on all my trucks and they work great, no idling but a nice warm truck when started.

after 2 of these cold spells in a row I will put one in my next truck for sure or the next engine if I keep this one.

Truth.

This article is about the dumbest [censored] I’ve read. It is ALWAYS best to allow the engine and lubricants to reach normal operating temps before driving the vehicle. It’s even more important in temperature extremes(cold).

I have always just started the engine and start driving. Slow for the first couple of minutes so the engine can warm up.

My Cummins takes a long time to warm up. I used to drive 3 miles in 10 minutes to work and by the time I got there the water temps had only warmed up half the way to normal. It helped putting a piece of cardboard between the radiator and intercooler during the winter but stil takes longer than my gassers.

What grasshopper said about moisture in the oil is true. When you shut down the engine and it cools some moisture is drawn into the engine. If you don't warm it up or drive it til the engine oil gets hot the moisture does not get removed from the oil.

Start it up and drive and quit wasting gas. A idling engine gets 0 MPGs. I just avoid hard acceleration with a cold engine same as my boat.

I’m a warm up guy…….It seems to me you can hear when an engine sounds right, plus how does it hurt to get things going prior to putting load on an engine?

Remote starting is the best. And a warm truck to start my commute.

Sorta like foreplay. You want to warm her up and ease into it.

Idling runs lower oil pressure and typically cooler motor which has less complete fuel burn more carbon and fuel dilution of the oil, simply put idling does more harm than good. I’m in the start it let it build oil pressure and run a few seconds then drive away gently. The used oil analysis I have done says it’s not hurting a thing and likely good for it. With a diesel i do plug in the block heater below 50 degrees it warms up faster, but it easily started the coldest morning of our last cold spell without as I wasn’t planning to drive it and didn’t have it plugged in.

I might run mine 2-3 minutes before driving off and that's it.

My '18 Silverado (5.3 gas) will idle up to about 1,000rpm on a cold start, I allow it to run until it drops back down to warm idle speed (around 500rpm) before I take off driving. It's SOP in all fuel injected vehicles/boat in my stable. My carb'd truck and boat get a good 5 minutes to warm up before moving. Guess I've been doing it wrong for the last 35yrs or so, but oddly, my stuff usually lives just as long or longer than most other people's that I know.

My new Ford F-150 owners manual even calls it out specifically. It says there is no need to let the truck warm up, just start it and go. I thought that was strange. I will try and find it.
