I was just wondering how many of you guys/girls let your car(s) warm up before going somewhere. For example: Wake up in the morning and start your car and let it idle for a few minutes to let the engine temp warm up. Or do you jump right in, start it up and put it into gear asap and go. I always thought that was bad for the engine/transmission - because it didnt have enough time to circulate oil/fluid. I know that once the car has been driven/warmed up - parked - then started and ran with the temp already at a good place, then that is alright. I usually let mine sit and idle while i am inside on a COLD day with the heater on, that way when i go to my car it is nice and warm inside and the engine is warmed up as well. Is that bad? I apologize for any confusion.
