Re: Irrelevant digression on the warm-up thing

[Steve Moresi <smoresi@domain.elided>]

I would like to agree with you John, and argue that the rolling warm 
up is even better for your engine too than the static warm-up. (Of 
course this is bound to start a war!)
My logic is this:
The engine wants to run at a constant temperature for parts 
clearance/wear issues.  The more quickly we get to that temperature - 
the better, right?  Going out and straight into an Italian Tune Up 
would warm up the car very quickly, but on the way there all the 
cold, unlubricated parts would tear themselves to pieces.  On the 
other hand, sitting in the driveway warming up your car puts no real 
load on the engine - warms up more slowly - leaving cold, 
unlubricated parts for a longer period. So we find a balance of slow 
easy driving to warm-up with a minimum of wear.

Whaddaya all think?
