Differential Fluid
I plan to change my Differential Fluid this weekend.
Question is, is what Brand do you guys use? Also whats the GM additive I need. People say you dont need it but i figured what the hell it wont hurt to add it.

For '99-'02 cars, use synthetic 75w90 (GM LSD additive is optional).
For '98 cars, use conventional 80w90 + GM LSD additive (required).
