G80 needs LS additives or not?


Recommended Posts

Hi, My rear differential is GM (SU8 with G80 positraction limited slip & GU6 3.42 ratio). I am about to change the differential fluid. Is ACDelco 10-4122 (GM 19368514) 75W-85 DEXRON Low Viscosity Gear Oil right one? I’ve read some say G80 needs LS additives or others say “no”. I think G80 doesn’t need additives but please confirm it for me. Thank you.
