Man, I could tell you some of his theories that would knock your socks off!You can let him know I started my 2012 Cummins powered Ram yesterday at work in 10F. It has Mobil Delvac 15W40 in the crankcase. It was a little slow to crank but fired right up and idled away at 1000RPM like normal at 10F. Grid heater cycled a few times, exhaust brake on and in less than 5 minutes I was driving home.
If your cousin's theory was true us "northerner's" would never leave home from December until March...
Just my $0.02
