i was given a case (12 quarts) of redline 75-85w gear oil i was wondering if you guys think i might have any problems running that in my tranny/tcase and my diffs. I just dont know if its a whole lot thinner than 75-90 or if its fine. then i was told you should run mt-90 in the tranny, but it seems like this stuff would be alright? Please correct me if im wrong. thanks
