    What about Royal Purple Max Gear 75w-90? I was surprised to see what it says on the back of the bottle...
    "Max Gear is a versatile, synthetic, non-corrosive, extreme-pressure hypoid gear oil. it excels axles containing open, limited-slip, locker, and spool equipped differentials, Max Gear is also outstanding choice for transmissions and other gearbox applications requiring a GL-5 or GL-4 gear oil.
    Max Gear is non-corrosive to soft yellow metals (Brass, Bronze, Copper)...
    This product is NOT for use in wet-clutch systems...."

    Assuming that you're not looking for Corvair advice, it's fine to use (though a bit expensive). The final drive is in no way connected to the transmission or clutch.

    I use it on my RX-8 which has Synchromesh, after Tons more of research on that, it seemed to be the best and after 2 years, feels great still!
    I just happened to have some extra!...

    I used in in my Zuma 125 that I used to own, but then I was pushing the final drive pretty hard the way I had the scooter set up.

    After reading all the threads to do with what oil to use, I think I will go with Motul 3000 20W-50 4T Four Stroke Mineral oil as iam in England , JASO MA approved to ensure perfect operating conditions for wet or dry clutches.
    Any objections ?

    Specifications and certifications are more important than the brand. Mogul is known to represent their products accurately, so use it.
