There is nothing in the market better than Amsoil and will serve very very well and reasonably priced ($15/Q)
Just about ANY synthetic gear oil can do that!! Are you really saying the Amsoil is better than Delvac 1/Mobil 1, Motul, Redline, Royal Purple & all the other synthetic gear oils? Come on man....Differentials have been living 200,000 with 80w90 Dino gear oils & no maintenance since the 60's.
