Personally, I would (and did) go for convenience, and head on down to the local auto parts store where they have a great selection of excellent hypoid oils. I like Valvoline Synthetic combined GL-4/GL-5 rated. Don't get just a GL-5, get the combined rating.

As I understand GL-5 is the best for ring & pinion gear loads, but GL-4 is best for synchonizers. With a transaxle like we have, you would like to have a combined rating.

Also, if you have a torsen type limited slip, you probably don't want the Royal Purple or Red Line super exotic type oil that has some kind of friction reducing semi-solid beads in it. As I understand, that can reduce the effectivness of the limited slip.
