I use Valvoline Full Synthetic 75w140. It's formulated for limited slip differentials so no additives are needed.

Mobil Synthetic is also popular.

I use royal Purple 75W-140 synthetic gear oil and AR-9100. RP is a little more expensive then other synthetics and it is available at Advance Auto. I also have a larger diff cover that increases my capacity from 3 to 6 quarts.
