I just use 80w90 standard dino oil.  I have an ARB so i don't know if you have a limited slip and if the ford LS requires an additive.

if you have a ford limted slip differential you will need the proper ford lsd additive. or a diff fluid that has the additive in it. the ford additive is a small bottle of blue fluid that stinks like you wouldnt believe.
