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.

Thanks for the Info. My brother tells me to go with 85-140, is that too thick?

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...
