Going to try Amsoil Severe Gear 75-110 instead of RP Max Gear 75-90*. I didn't put any friction mod in with the RP, do folks add any with the Severe Gear? I didn't think the amoils had any already in there, but their site does say "Contains friction modifiers for limited-slip applications" My plan at this point is to start with none and see how it goes, but curious what experience others have had with this particular diff fluid.
