Royal Purple Gear oil...

[mynameismike65]

Just want to double check that I need 3 quarts, and that I DONT need any friction modifier? (installing 4.10s in 8.8)

Thanks

I ran it when I had a clutch pack. No modifier is needed.

The friction modifier is already in the Royal Purple 75-140, it's not needed. And yes you need 3 quarts.... It's actually slightly less than 3 quarts... I think like 2.25 or 2.50 qts for the ford 8.8
