I use Mobil 1 also, 75w90 weight. The above post does give good "how to" instructions.
The Rubi has an E locker and it requires no special additives, some limited slip type differentials might, but not your Rubicon.

Well I just threw on ARB covers on '10 Rubi and put in Royal Purple. Just follow that thread on how to do, really easy. I am a believer in you get what you pay for.

I had a friend who's camaro was on Horsepower TV. He had mobile 1 in the engine and rear diff. The show dynoed the car, then changed the engine, trans and diff over to royal purple. When they dynoed again they picked up 8 hp at the wheels. I've been sold on it since for diffs and transmissions.

If they put in all new fluids (Brand X), did the dyno and then replaced the fluids with new Brand Y and repeated the dyno, that would give data worth considering.
Otherwise it is just old fluid vs new fluids. With the tranny likely the biggest influence. A still better test would be to change only one variable at a time.
And, of course, repeat!
