PSDLOVER, did you have to add friction modifier with the Royal Purple? I have the new ford finned cover, permatex and RP to get mine done. Trying to figure out if I need to get the friction modifier.

No friction modifier is needed with Royal Purple . The cap. of a dana 80 is 8.3 pints and it calls for 75W90 not the 75W140 that the 10.5 Sterling axle uses.

It just goes to show how brain dead I am today...I quoted the wrong post.
I meant to quote HookedOnFuel's question about the capacity.
I do the same thing. I buy a big jug or two and start pumping it in till it spits it out.
