Need quick answer...can I use this oil in my diff?

most likely.... make sure you put some limited slip additive in it aswell...

(you could always just buy some stuff you know will work well)
 
Ya I was going to buy some stuff until I found this. Plus I have done a search and asked but no one can give me a definitive answer as to what oil to put in there.
 
That lube should be fine, 80W90 is the recommended fluid. As Cam mentioned, make sure you add a bottle of the Ford friction modifier, C8AZ 19B546 A, now Motorcraft CXL-3.

cheers,
