Its time for me to give my 1980 Vette some attention(52k Org miles).I need some recommendations for differential fluids and is there a better posi additive or should I just stay with the GM posi additive.
stay with the GM additive and either 85-140 or 80-90 gear oil. No special snake oils needed beyond those.
I would use 80-90.
I would use 80-90.
