Royal Purple 75W-90 okay for the diffs?
I want to change the fluids in my diffs as they haven't been changed in 105k miles... My dad has a TON of 75W-90 for his Jeeps and offered me some... It isn't too far off of 80W-90 so I don't think there would be a problem... We hardly ever see anything below 20 degrees and nothing over 95 degrees... Year round is usually 40's to 60's... Typical depressing Western Washington weather... I have the 9.25 rear with the corp diff... So no friction modifier for me...

You know I have heard that oil is okay, but I am not going to say one way or another.. I recommend Mobil

I know that people use it but I don't like it!!!!!!!!!
Go Mobil One 80W-90 Fully Synthetic for the correct additives needed.
If I remember right Mean Green is running it right now as well as other members so maybe a PM to him.
