    Lots with more in the works
    I use Redline 75W-90 GL-5, which I believe is synthetic, in both diffs. Neither one are limited slip, they are both open in the 4Runners.

    80w 90 would most likely be conventional oil.
    75w 90 will be synthetic

    All I get is this little box?!
    Mobil 1 75w-90. I personally buy the stuff from Toyota for the transfer case but I'm just paranoid.
