In my bashers I always used a heavier wt oil. When I rebuilt my XXL diffs last time I decided to go with 15K F&R rather than my normal 30K-F and 50K-R. I had them this week apart just to check after 2 dozen runs w/6s and the gears look great yet. I think with the heavier oils it was creating to much stress on the gear train, with the lighter oil a wheel will break loose much easier and reduces stress ??
