I've used both Mobil-1 and Amsoil. Didn't have any problems with either one.

I agree with "dustyloins" truly you just can't go wrong. If you feel ambitious, and like to see bickering, search up my name and you can see a good thread on this subject.
Red-line also makes one hell-of a good diff oil.

I just had Amsoil 75w-90 put in my 04 Ram with only 1,000 miles on it. Should I have waited until it broke in more before making the switch?
