In MN we had the "Polar Vortex" a few years ago. We didn't get above zero for something like 30 or 40 days. My 1500 functioned just fine with the standard oil. I used Mobil1 synthetic in that truck, and I never had any issues.
I would just use a good quality 5w-20 oil and call it good. I would also suggest synthetic oil too.
"We didn't get above zero for something like 30 or 40 days." Oh come on that can't be right! There is global warming don't ya know!
I highly suggest as you said... good quality synthetic oil. Synthetic doesn't break down or thicken up nearly as bad as regular oil.
