It states to use SAE 90 hyopid oil that is GL-5 rated and to use SAE 80 in colder climates. The only place I have seen just SAE 90 is at the dealer. What is everyone using? I would prefer to use synthetic oil in the rear. I have Mobil 1 75w-90 synthetic gear lube, but it does not say anything about hyopid, of coarse it's GL-5 rated. And by the manual you have to change it at 600 miles, but never again. What's up with that?
