Motul Gear 300 LS

Is anyone running Motul Gear 300 LS 75W-90 in the rear diff? If so, any pluses/minuses? According to the Motul spec sheet, it's rated as GL-5 and formulated for LSD diffs. Thanks!

Motul fluids in general are pretty highly regarded so I would think that the Gear 300 LS would be a high quality diff fluid. The Motul website recommends Gearbox 80W-90 for the Z's diff, which is rated as a GL4/GL5 fluid. I'm not sure how the two fluids compare, but since the Gear 300 LS is rated GL5 and is specifically formulated for limited slip diffs, it should work. You may want to check with Motul directly. The only downside I see is cost ... Motul fluids are usually pretty pricey.
