Just wanted to see if anyone use these. my 2004 is in need of a f&r diff, tranny fluid change...thanks.

Does Lexus of their own proprietary 75w-90 gear oil? or any run of the mill should work?

I am looking at getting some full synthetic 75w-90 maybe

I searched and there not much discussion about gear oils....

 

I used Mobil 1 Syn 75w-90 when I did mine over the summer.

I wrote up my experience here:
