That's true about wind chill being insignificant other than to cool down a warm engine faster - only down to the same temp as if there were no wind. HOWEVER - always struck me as odd that if my car is in my unheated garage at the same temp as it is outside it'll start, if it's outside it won't.
0-30 oil all year round in the truck - huge difference in startup racket and oil pressure is immediate. I plug in at anything under -10 on a 2 hour timer, 4 hours under -30, go to Mexico under -40!
