Any thoughts on Diff fluid?

[HS-LD]

Any thoughts or ideas regarding the best diff fluid to run with the lockers?

Mobil 1 LS 75w90? Red Line 75w90?

Probably all would be OK, I'm wondering what would be optimal.

Is that Mobil synthetic? I don't think you would go wrong with it. Ultimately it's nice to use something you can readily get if you need to in a pinch. I try to standardize across the board with all vehicles where possible. Just write down somewhere what brand you put in it (whatever you decide).

I recommend Amsoil or Red Line. I had a problem with the factory brand diff fluid in my Titan burning (tuning black) when towing. I switch to Amsoil and it says amber even though I'm towing much heavier now.

Mobil 1 for me... honestly any synthetic will do... you can put motor oil and it will work in a pinch... diff oil is not picky unless water gets in...

When i replaced mine it was clean after 40k miles..

Amsoil Severe Gear. I run 75W110 in the rear end and I run 75w90 in the front. I signed up as a dealer because I like their products, and now many of my buddies are getting hooked, too. Let me know if you need any help.
