    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.

    Now using regular Valvoline M/C 10W40 for everyday riding in my '82 Maxim 750. Used to ride a 920 Virago and my mechanic loved putting Mobil Synthetic Regular 20/50 from Walmart in this bike. On a ride some months later I was trying to pass a car on the 4 lane so I opened up the throttle to do so, only to find the motor was doing great in rpm's BUT nothing was being transferred to the rear wheel ......... clutch slipping like crazy ............ lesson learned. DO NOT USE synthetic oil in an '82 bike !!!!

    I'd venture to suggest that particular synth oil had a low-friction additive package in it, which your clutch didn't like. Same applies to a lot of the latest car oils - steer clear of any that say 'energy conserving' ' fuel saving' and that kind of guff, as they will have low-friction additives in them. Synth oil on its own is innocent of causing clutch slip.
