some people say you need the limited slip additive but if you have good synthetic fluid that is GL5 i beileve you don't need it. I know Kendall gear oil is approved already for limited slip. with the G80 i'm not sure you need it at all.

I am using Amsoil Severe Gear 75W90 with no additives. It is GL5.
