    Rear Shaft Oil

    Anyone used fully synthetic SAE 80W-140 gear oil for the rear shaft drive? I have some of this sitting under my workbench and thought it would be good to use for the next change. It is GL6 rated and not cheap. :305:

    I think that's thicker than what's specifies but would be ok imo.

    Personally, given the cost of oil vs cost of final drive, id stick with what Honda recommend.

    Thanks Fredz and Hartley. I was just thinking that given the conditions of our summers downunder it wouldn't hurt to have a more heat resistant oil in that drive. :305:

    I wouldn't say it's more heat resistant, just thicker.  GL6 will do the job nicely though being thicker it will 'absorb' a tiny bit more energy from the donk, but I think the 1200 can handle it.

    SAE  80 is in the manual
    its been discussed on here before, and i think got a little heated.
    Honda knows best i'm sure!
    so no to 140 spec

    SAE 80 is a generic name for what is typically specified as Gear Oil 75W-80 or 80W-90 API GL5/6.  As the OP's oil is a higher spec than recommended it would be ok to use in the final drive.  The only downside is it's thicker.  Using the manufacturer's recommendations is always a good thing to do, whether it be for oil, tyres or fuel.
