Is there any benefit from running the 75w90 syn gear oil as opposed to the 75w140 syn the manual calls for? I have heard mixed things about this.

Im getting 4.10's replaced with 3.73's and all new bearings. Im thought about using AMSoil, but I will probably end up going with Mobil 1 just for the simple fact that I can get Mobil 1 anywhere (and i dont like mlm companies). What is your thoughts?

Im running 75w90 Mobil 1 synthetic in my rear. No problems at all and its as quiet as stock. I only went with 75w90 cause thats what Autozone had.
