Does rear differential use same gear oil as tranny?
If not, what kind of oil should I get?
I use GL-4 redline MT-90 and can I use this on a differential too?

No, the diff uses GL-5. FSM calls for 80w90, but I use 75w90 Mobil 1 Synthetic. Most companies that make a synthetic only make it in 75w90. That's not to say YOU have to use synthetic, I just prefer it since it's only a few bucks more.

If you have a Kaaz LSD, don't use synthetic, but if you still have the stock open diff, or a VLSD, go for synth. Although, regular fossil oil will work just fine for any open diff.

open diff? use vegitable oil..water, who cares. its useless buy the CHEAPEST you can for open diff
vlsd maybe a bit more expensive but not much.

80w90 gear oil in my S13 viscous. It cost $3 a bottle I think, works great.
