TDR did a study on oils last year or at the end of 07. I can not remember when. but regular rotella came in near the end of the oils. But the Triple protect was a good oil.

I am running Royal Purple 5w-40, about 5000 miles on it so far and no problems. I am going to send a oil sample at 10,000 miles when I change the filter.

I don't see any issues but I'm sure there is an amsoil commerical and j-junk stuff coming. Rotella bottom or top makes no difference, I haven't seen anyone keep their truck long enough to prove any point. No one pulls or hauls more then Kodiak and his trannys give out before the engine and he uses amsoil. Long/short you'll be fine. Enjoy the ride. :party018:

Ditto. The main thing is to service regularly and your truck will last many years. Oil brand is more personal preference than anything. Proper viscosity and rating type is more important.
