    Yes sir we do. It's LE gear oil. I my opinion it's some of the best oil on the market.

    That is some of the best oil available. I agree. BUT. I have told this story before, but I'll throw it in here. This is a first-hand, seeing-is-believing dealio.

    I used to drive a C3500 Cab/chassis with a 19' alum tilt-bed car-hauler AND a steel single-car trailer behind it. I would haul two cars over "the Grapevine" and back three times a week or so. This is a 6-7% grade, about 5-6 miles of solid climb each direction. This one-ton had a 454 with 4-speed and we put a DougNash 22% overdrive behind it to split-gears and give some highway cruise RPM reduction.

    Well, as cars got heavier, we started cooking the lube in the OD unit. It is similar to a 2-ton 2-speed rear end mechanism, where a submerged motor runs a threaded shaft. The shaft loads up a spring that shifts a fork forward/backward depending on OD on/off. The lube would get so hot that it would cook the electric motor and quit working.

    We tore it down several times, replacing the motor most of the time and all of the seals (hard and brittle). We (me and the owner - an ex Baja 1000 Jeep racer) loved Valvoline. Ran it in the motor, trans, OD, and rear end - respectively. So, we switched to StaLube synthetic, since the Valvo wasn't cutting it. Cooked it too.

    Castrol had a synthetic and we also tried Royal Purple. No luck. Same scenario. We never tried Amsoil, or RedLine, though. However, our local LE dealer said to try this new (at the time) "red" syn gear lube. He guaranteed we couldn't cook it. We did. Obviously we were loading this thing up with too much stress, but we were very easy on shifts and usually reduced down to one-gear-lower than it could pull on either climb. No unnecessary abuse.

    The owner said he used to run Torco in the diffs and Xfer case of his race Jeep, since they were a sponsor. He said he never had any gear lube issues in all of his races. So, we loaded it up with Torco. I ran it over and back and we drained it - looked new. Loaded it up again and ran it over TWO times. Checked it and it looked great, so we left it in. I ran it until our next service interval and it still looked great. Had I not saw this for myself, I would not have believed it.

    Since then, I have always ran Torco gear lube in trans and rears (respectively). I run their RTF (racing trans fluid), which is a syn 75W manual-trans fluid in my Bravo-1 that is STILL GL-6 rated! GL-6 is obsolete as there is nothing that has that harsh of gear pressure anymore.

    It is suggested for all manual transmissions, gear boxes, differentials AND MARINE OUTDRIVE UNITS that require such lube. I run it more than 100 hrs and it still looks great each time with bare-minimum metal on the drain plug.

    So, if you are happy with the LE, there is really no reason to change. If you are gonna be throwing some more HP to it or want the VERY best - give it a try. It is a bit pricy at $15 or so per liter (comes in 1 Liter bottles, just over a qt), but you CAN'T hurt it.
