Good quality oil for my gearbox and rearend
I use Royal Purple Max Gear 75W-90 in both my AX15 manual transmission as it's "yellow-metal" safe for the bushings, and my Chrysler 8.25 rear end as this is an acceptable weight oil for it. Never had any problems with my transmission and since I'm rebuilding my rear-end I decided to spring for the quality stuff. Would recommend

I love Royal purple products
This is a great product and it was available at a decent price. I especially like that I don't have to use a special limited slip differential additive with the Royal purple product
