    make your own per the service manual description...50% ATF trans fluid and 50% straight 30 weight motor oil... thats whats in my bikes as well as many members here using the same formula.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      I blend DexronIII and 20wt engine oil to use in my forks. (I'm "frugal" also)

      DexronIII is around 8wt and has nice anti-foaming properties to boot.

      if you do blend ATF and engine oil don't use type "F" fluid; it has metal particles in it.

        resurecting old thread

        **Just going through my old posts looking for any new added comments.**

        A thought occurred to me with this thread.

        A lot of suggestions that include different weights of oils. 10w, 15w, 20w mixed with trans fluid etc etc...does human body weight come into play with this? I don't know whats in my forks, could be fish oiil for all I know, (never did get to changing it) all I know is the bike still seems to jolt over the small cracks in the road.
        I'm in the 220 lb range . Just curious if some of these responces are from 100 lb guys?

          I'm about 280 pounds and I regularly whip my GS850 like a rented mule over the worst pavement Indiana has to offer.

          FWIW, I use 20W fork oil. Everyone else gets 15W.




          Crikey, only the skinflints on the GS forum could get their panties in a wad over the cost of fork oil. You guys are legends among the ranks of historic tightwads.

            Had 20weight in my 85 750s forks,got it free .When a stupid mistake meet I had to change seals I got some 15weight.Like it much better,the 20weight was a bit harsh.
