I got this in my school FYI email:
I think my engine and transmission oil needs more time than that to heat up and work properly. Also, suddenly driving off with a cold engine block is a good way to develop cracks in the cylinder walls - which is why you don't just pull the throttle all the way out on an airplane. You gradually reduce it back to idle.
Brewski, give me your expert advice.
Idling is not an effective way to warm up your vehicle, even in cold weather. The best way to do this is to drive the vehicle. With today's modern engines, you need no more than 30 seconds of idling on winter days before driving away. In fact, idling an engine for two minutes uses about the same amount of fuel it takes to go about one mile. So, you can save money, emissions, and time if you just get in and go!
