If no mods, most important thing is to make sure it is CJ-4 rated.

Rotell T 15w40:tu:

Amsoil 5-40 in the winter and 15-40 in the summer with their oil filter.

cj4 amsoil 5-40

x2

they're all the same if they have the API and SAE stamps on them :)

SAE 15W-40 and make sure its CJ-4 rated is what the manual recommends.

Rotella, Amsoil, Super-tech oil all meet those requirements

i run the royal purple 15-40 and their filter havent had a problem with it yet been running it since i got my truck and i put it through hell everyday.

I would strongly urge you to use Amsoil. I am not selling you on the idea, but from experience it really works.
