Hey dude,

I've used the SeaFoam before, but WTF is Marvel Mystery Oil???

I'm gonna do my diffs and trans soon, maybe I will go the Royal Purple route. Summit sells it over here in Reno. What sort of LSD additive did you use in your rear diff?

I even jack up one side of the VX to get more old oil out. I use Royal Purple followed by a quart of Marvel Mystery Oil in the motor at every oil change. I also use Royal Purple in the trans, t-case, and diffs - and, no, I am not a salesman!
