I was on an " Oil " forum , some time ago . It stressed the issue of a cold start .
Best I remember , I think it said most of the engine wear occurs during a cold start , when oil is not circulating properly .
I am guessing the engine will last longer , the quicker it comes up to " tstat temperature " . ( Of course fuel burn is probably more efficient when the engine is at normal operating temperature . )
I have seen many diesel trucks with methods of controlling winter air flow to the radiator .
Any way to make it adjustable for your car ?
God bless
