Oil for 9" trutrac
#4
I use Schaeffers 267 80W-90 gear lube & will never use anything else. Mine's an 8.8, not a 9, but does have a true-trac. BITOG website will confirm my opinion regarding Schaeffers. There's alot of oil product test results on the site as well.

Why is that? Just asking becouse i have ran 80-90 and now i run 85-140 weight recomended by my builder and would like to see how you answer this question. 140 weight will help for cars with gear wine also especially if you have a tunnel mount tq arm which i run that are known to cause a good bit of gear wine after install...
