How long do you let your car warm up for? How long do you let your car cool off for?

sanely for the last few miles of a journey as cool-down. At the track, though, I don't shut the engine off until the temps drop below 225.

I think it makes people feel better but I find that the warm up is important, cool down not so much. Next time on a hot day after the car is all warmed up. notice the temperature of the oil .. then turn it off and leave it for 10 minutes and come back and turn it on .. i bet the oil temp will be even higher. its a losing battle.

But if I ever run real hard and get my oil above 200, then cool my car down and then start it up 10 minutes later, my oil temp is definitely much lower, like barely over 150.
