Best Differential Fluid?
Can someone please point me to the best differential oil in your opinion? i was looking at Amsoil (forget the weight, i believe 75w-140?). i will be replacing both front and rear, how much do i need? thanks!

well if under warranty you can't use the amsoil. you need a full syn and if you have a ls you need the additive. find some connoco synthetic gear lube its the same as the motorcraft oil but half the price or royal purple. www.karlracing.com
