is this OIL for rear end , good????

[east_sidaz40]

I just came from ford , and told them i need axle oil for my car. I'm puting in the FRPP 3.73 . The gave me SAE 75W-140 ("Synthetic" rear axle lubricant). Will i need Friction modifier to go with it? someone told me that i wont neet it because its already synthetic!!?

Yes, you should add 4oz of the additive also.

I'm not sure about your particular oil, but I read the side of Royal Purple gear lube and it said it contained friction modifier. Just read the side of the bottle and see if it already has it or not.

The ford gear oil is a good oil but you will need to add friction modifier to it. it comes in a seperate bottle. also can be bought at ford.

well It clearly says on the side : "For limited slip rear axles. consult owner's guide.May require the addition of a friction modifier meeting ford specification"

BUT when i asked the guy in FORD spare parts , he told me i wont need friction modifier. because this is a new modified rear end Oil which already HAS friction modifier. ????? so what the hell now . I'm thinking if it already has friection modifier , why does it say on the side , that the addition of friection modifier might be required!!!!!!!!?????

anyone

I have found most parts guys don't have a clue as to what goes into every different vehicle or what is required by the manufacturer. If the oil you are using and your manual says to use the friction modifier, then I would use it.

If the manual and the bottle say use it then do so.
