Oil Pressure
#31
The point about using thinner oil when temps are below freezing is valid but I've never done it myself and never had any issues at sub freezing temps.
Try 15w40 or even 20w50 if you haven't and see how your engine runs. Especially before full operating temps are attained.
Personally I would not put 5w anything in my truck. Lost an oil pump and cam shaft in 38k miles running 5w30 because that's what the dealer put in it while it was still under warranty.
