Differential Fluid ?
I'm about to change the fluid in my rear differential and would like to know how much gear oil I need? I also have a posi (g80) and was wondering if i still needed to use a limited slip additive (i think i saw on a website that gm no longer needed to use one but just making sure). I know gm recommends a 80w-90 gl-5 oil.

Re: Differential Fluid ?
You remember how much i need? Also, Mobil 1 makes synthetic gear lube but it only comes in 75w90 or 75w140, would it hurt to put in the 75w90?
