What gear oil are you running?

[00WHTSC281]

I developed a small leak in my diff. cover. So im going to change it out this weekend. I thought I would see what everyone else is using. 75w90 or 75w140. I was thinking RP, Amsoil, or redline.

I just put amsoil 75-140 severe gear with amsoil slip lock in mine Saturday.

I'm still undecided on the whole 75/90 75/140 debate....

I run the 75-90, lately been using the Lucas synthetic

I spent hours looking at the whole 75/90 or 75/140 debate and said screw it and got good amsoil in 75/140 I am not sure which one is better but I figure it's better than no oil or bad shape oil as mine looked rough.

To me you want the lightest weight that still gives you the protection you need. Mines not a track car so I think im going 75w90. Just got to pick a brand.

I think 75W-140 is what it came with from the factory, although you would probably be fine with either. Just don't forget the friction modifier!
