Correct answer there.
Warming the car up obviously is based on other factors. Ambient air temp, engine temp at start up, throttle position during warm up.....
I always try to get the oil temp up to 140* or so before really stomping on it. Thats a temp I've heard before and sounds reasonable to me. Better safe than sorry.
