Limited Slip Treatment?
I just purchased some pennzoil gear lube for my rear diff and it says on the container "it does not need a limited slip top treatment nor is one recommened". I picked up a bottle of ford friction modifier, think i should go ahead add it or leave it out?

I used Castrol Synthetic with the Ford Friction Modifier when I installed mine. Not sure if the bottle said to use it or not, I didn't even read it, but I put it in anyways. 
Almost 500kms so far and all is good. Not sure if the Penzoil stuff is much different, maybe someone else here has used that specific stuff.

GM Friction Modifier is one of the better ones out there belive it or not. ( I worked for Penzoil / Quaker-state and the gear heads there seem to think the world of it) I've been running it in my Mustangs and f-150. Never any problems
