Royal Purple max gear 85-140 the best oil you'll ever use!

ok well i guess my real question is what weight oil to use???

85-140 is what i was using, but it was Curries side brand...9plus. so my real question i guess is does anyone use convention weight.....85w-90? the 85-140 is obvoiusly thicker but in a race application is it that important or will standard automotive weight oil work ok? so does anyone use 85w-90 gear oil in their race cars or just the thick stuff?

why dont you just use your "rear end lube"

[Project1500]

Straight 85-140 for your setup.

stick to the 85-140 in anything seeing high impact use. (ie. anything off road)
