Brand doesn't matter. Oil is oil.

Just stay away from Sta-Lube and Coast. Buy half decent quality stuff. You dont need synthetic in a jeep, its just going to get changed almost as often as your engine oil anyways.

how's lucas oil ?

Lucas is GREAT stuff. I run it in my Jeeps. The only real benefit is you don't have to use the limited slip additive if you have a l/s in you diff.

It is a little pricey for what we do though.
