Heck no. I just tend to let anything warm up a bit in extreme cold. I don't care what the "experts" say. Excessive idling isn't good, and the engine will warm up quicker under load. But, I believe the rotating assembly - the pistons and such, should reach some kind of temperature before placing them under that load.

Not to dis you but there is a flaw in that theory. Not that there's anything wrong with synthetic but the engine still needs to be up to operating temp for all the parts to be happy together. Most, if not all, of the contamination of the oil takes place during the warm up and synthetic is not immune to this contamination.
I used to run shops in Anchorage and I'd see those commuter cars come in with 1000 miles and the oil is way past due for changing. Routine: cold start, drive 3-4 miles to work, cold start and drive home, maybe stop at the store and let it get cold again. Hell on oil.

Willow as with all Q & A there is a possible yes answer, possible no answer and a possible maybe answer.
You bring Alaska into the conversation A place of extremes that most of us will never encounter. For places like Alaska there is a different set of rules.

Engine warm-up and synthetic oil
So a good approach would be to keep the engine at high idle with the manual chock pulled out so the truck coasts on its own until the oil pressure comes up. I'd never thought about using synthetic oil in an old engine. Would it be OK to use on my original 6 cal 240 with ~ 180,000 miles on it? Still going strong.
Thanks to all of you for the information. Bert
