John, it was my understanding that it is better for the engine and vehicle to
warm up by driving off at conservative speeds keeping the engine rpm in the
lower half of the torque band. Its one of those things which I just never
doubted and never thought about. I'd like to hear the wisdom of the List on the
pros and cons of either procedure.

PS its not a matter of rushing
