Textbook answer from Shaker.

I'm one whom prefers synthetics in rear-end (considering the limited service interval, I think it's a few bucks well spent).

If going that route, check with the fluid manufacturer, as some fluids have friction modifier integrated into their blends (too much modifier isnt great for performance).

Good luck.
