    Your “auto LSD” just uses the brakes to approximate a limited slip diff. There’s no need for friction modifiers or anything of the sort.

    I used mobile one synthetic 75-90 personally, but anything synthetic is fine.

    Are you doing the transfer case as well?

    I haven't done the Front/Rear Diff or Transfer Case fluid change yet myself, but it was recommended that I use 75w-90 for the Diffs and Ravenol 75w for the Transfer Case. For the Diffs, it was also recommended to use the Quart Pouches like this
    $16 Valvoline FlexFill Advanced Full Synthetic 75W-90 Gear Oil 1 Quart Pouch
    Valvoline FlexFill Advanced Full Synthetic 75w-90 Gear Oil. Here's the link for the
    RAVENOL J1C1003 MTF-3 SAE 75W Full Synthetic Gear Oil - 1 Liter for Manual Transmissions, Differentials & Transfer Cases
    Ravenol 75w too. The 75w-90 gear oil can be found just about anyway. The Ravenol you'll have to order online.
