LSD Oil Change Question

[kuwe34]

I was thinking about changing the oil in my differential, and was wondering if I needed the additive for the limited slip. I've looked online for a while and no DIY article has mentioned it, so I'm not sure, what do you guys think/know?

No, just use synthetic 75-90.. at least i think thats what it was, correct me if im wrong

You shouldn't need friction modifiers in your fluid unless your diff has a static lockup over 25%. If you're diff is from an ///M, you will be fine without the addative because I believe they are all 25%.
