Differential fluid?

[ramp]

What is the recommended differential oil for a 3.46 LSD?

For those of us who use Redline, go to their site and snoop around and also look at their application guide. Believe 75/90 is what you seek.

GL5 for the diff. Some folks like synthetic, I am very happy with regular dino. gear oil. Don't put in any kind of friction modifier.

Recline Gear Oil 75/90 is the one I use in all vehicles, including previously owned e24 and e28 with LSD. Made the mistake of using the *NS version on first one, had to add friction modifier to stop the noticeable chirping/chattering at low speed. The clutch packs need some slipperyness to prevent premature wear.

I used Redline 75/90 based on lots of feedback and reading. As posted above, it has friction modifiers already in it for LSD.
