Usually about 10 seconds to let the oil circulate a bit. Unless it’s freezing out then I will let the heater warm the interior up. Warming the engine is a side benefit.

Of the 3 vehicles...

Newest one...I let the blue 'engine cool' light go out. If freezing... usually 10+ minutes.

Middle - large SUV- usually 1-2 minutes, longer if freezing so family doesn't get cold.

Oldest (semi-beater) - 20 sec. unless freezing, then longer

Part of the reason - we live in a smallish town...many places we get to in less than 5 min. Don't want to run the car for a couple minutes just to turn off luke warm.

If it's a turbo you should let it get warm before driving. A modern NA car, 30-60 seconds unless the manual says different. Wife's car has a light that extinguishes when it's ready. My car is a turbo, I wait til it's fully warmed up.

My car is set to start itself on work days at 5:40, I leave at 5:45-5:50 every day. It's at operating temp when I get it and auto climate control has the heater/heated seats nice and warm or the A/C/cooled seats running when I get in.

As for this time of the year I more often than not crank it and let it sit for about 5 minutes while I do something else to let the inside COOL DOWN.

I start my truck, check the gauges, then back out of the garage. Then it sits there running for a minute or two while I close the garage door, get back in & I take off.

If my wife's going along, and I have to wait for her to come out of the house, it could take a bit longer.

I wait for the idle to normalize in my Supercharged Turbo Volvo. It does take longer in the cold.

Too warm here to worry about it, if anything I'll start it and let it idle to cool the interior down with the remote start feature...

Usually just long enough to come off the fast idle. That's usually long enough to get the kids buckled in & ready.
On occasion, remote start while walking up, usually after work when it's been baking in the sun.

Its best to let your car idle for one minute to
get the transmission fluid running through out the transmission. I use my trip meter ... when it shows one minute.... I put it in gear and go.
Now....tractor owner manuals tell you to wait one
minute before lifting any attachment... for the same reason! Obviously auto makers want to sell you a new transmission many miles down the road!

Probably 20-30 seconds unless it's winter then a bit longer.
I think it's more important the way you drive it while it's warming up rather than how long you sit idling.

I start and i am off, My wife cries about it all the time but i don't listen.

The owners' manual for the last half-dozen vehicles I have owned, including bikes, specifically said NOT to warm them up.

Maybe 10 seconds before pulling out of the garage. Since we park our cars inside the garage, temperature isn’t totally in sync with OAT. Both cars are 2018 moe years.

Start and go. I drive it nice and easy until the operating temp is within the normal range.

I only warm in the winter and that's only for the transaxle fluid to get circulating.

Why Do People Still Think That They Have To Warm Up Their Car Before They Drive?

Does this myth still have any validity?

Warming up an engine was once a popular myth that actually had a lot of truth. A few decades ago cars were not built as well as they are today and benefited greatly from being warmed up before they were driven. We have tried to debunk this myth before, but it might not be that easy. Even though there is a ton of evidence to suggest that new cars no longer need to be warmed up, there are still a large majority of people who believe that they need to warm up their car before driving it. What keeps this myth alive?

I wait until oil pressure stabilizes.

The POH (Pilots' Operating Handbook) for every light (under 6,000 lbs gross weight) airplane that I have flown, recommends recommends against long warm-ups. The advice is, as soon as the engine is warm enough to take full throttle smoothly, you're ready to go.

I can't even remember the last passenger vehicle I had, that had an oil pressure gauge.
