All the new diesel trucks should be plugged in below -15*c........ Especially since they all have 15w40 in them. I'm not gonna plug in the next few days just to see what the 2011 cummins does with only 9000 kms on it. Curiosity more than anything. I still have the 15w40 on it after 2 oil changes, but will be switching to 5w40 synthetic next oil change and then shouldn't ever have to worry about not plugging it in. The black beast started no problem this morning in -28*c windchill, so i suspect in the -35*c windchill tonite shouldn't be a problem.
Oil pan heaters are great on older diesels, but don't really need 'em if plugging in the newer trucks as the newer block heaters work great(higher wattage).
Espar heaters work awesome too, but you're payin' $$$ for it
Just for the record...windchill doesn't matter. Temperature is the only factor in cold starting the engines.
And my 0.02 for the thread: as my dad always said "tie up your horses!" ;-)
