The SAF-XJ is supposed to be the best but Redline has a good rep too. I've used Royal Purple, Amsoil, and Mobil 1 and I like the Mobil 1 the most out of the 3, it kept the LSD quietest. The Amsoil caused diff chatter like crazy in parking lot situations. I'll probably try Redline next. __________________ ~Dave~
