We once had a post here from a guy who was responsible for diesel
maintenance on a fleet of trucks at a gold mine in northern Canada.
He said that basically the trucks idled all winter, over 3,000 engine
hours each. He said that by spring the engines were mostly junk if I
recall correctly.

I'm too lazy/busy to do the implied required search, as following this
group is a minor part of my daily activity, but my recollection of that
thread and observation of truckers in my own area tells me that keeping
the engine idling doesn't significantly add to the engine's demise. In
fact, if the engines are shut down in those extremely low temperatures,
drastic measures more injurious to to the engines are required to
restart them.
