TrueTracs been in the rear end for about 6 months now. I plan to drain the rear diff lube (currently Amsoil 75W-90) shortly to remove any minor impurities/shavings from the new diff install. Any reason I to choose, or not choose, Amsoil's 75W-110 over the more standard 75W-90? Would a loss in MPG's be expected? Not a serious crawler here...
Any feedback, or experience with 75w-110, would be greatly appreciated.

i wouldnt run 110w. 75-90 is what it calls for and what i put in it. marlin crawler also told me to use royal purple or redline fluids in our transmissions, not that amsoil will hurt anything, but i went full royal purple in the driveline
