opinions on mobils new oils
new long life oils that are supposed to last 5k,10k,and
even 15k miles.I always heard that the longer oil
is left in the crankcase that it will eventually
turn acidic and gum up.What's your opinion?
I'll still continue using GC 0w30 though, it's worked very well for me and until I can no longer buy it, it'll be my only choice.

The Cummins in the Dodge will continue to get Mobil 5w40 truck and SUV.
Patman is the new 5w40 truck/SUV oil any better than Delvac 1 or is it the same?
