75w90 is fine???

[ItsStock02]

Ive searched and searched, but cannot find a clear answer. I just purchased 2 qts of Mobil 1 75w90. Is that going to be fine for the stang w/ 373s?

Yes but u need 2.75 quarts and some friction modifier.




EDIT: God I can't type today....

This is straight from Mobil's website. So would I have to add the Ford stuff to it as well?

Mobil 1 Synthetic Gear Lube LS 75W-90 contains special friction modifiers designed for limited slip-type differentials. In most applications, the addition of special LS (limited slip) additives is not required. For axles requiring the highest level of limited-slip performance, OEM specific LS additives can be added to this fluid.

I would for good measure. But thats just me.

it probably wont hurt it but itd still put in the ford friction modifier. xl3 is the part number

 

[squeak93]

Add it. 7 dollar or so insurance. Thats cheap.
