I use mobile 1, 75 90 weight gear oil with one bottle of the gm additive. I am not sure how much you need, but just take the cover off to drain it, then put the cover back on and fill it from the fill hole on the top until it starts to just barely come out of that hole, when that happens, you have enough fluid in there.
