    Oil warning!!!

    As many of you may know, the "energy conserving" oils should not be used in bikes with wet clutches.
    This meant that any oil with a viscosity of 10-30 or thinner, with the higher number being the key, had the friction modifiers and should not be used.

    I have just learned this is no longer the case.

    Havoline (Texaco) and Valvoline have increased the level of molybdenum disulphide (the friction modifier) to their 10-40 dino oil. Their tech people now say DO NOT use these oils in an engine with a wet clutch.

    One of them says their oil has a moly content of 220 ppm, which is enough to harm the clutch.

    My cynical side tells me this might be a way to force you into buying their M/C specific oil, which is much more expensive.
    Then again, it may not.

    Anyway, there you have it, fair warning!

    You can still run diesel oils in our bikes. The rotella 15w40 or 5w40 synthetic are both good.

      As I said, AFAIK this is just the 2 brand and viscosities mentioned.

      And 15-40 being thicker than 15-30--the higher number used to be the key. If it was 30 or lower, it was the "bad stuff". The lower number didn't matter.

      I have 5-40 synthetic Rotella in all my vehicles.....oh wait...the GS is the only one with a wet clutch.....

        Just out of curiosity do these two 10w-40 oils say energy conserving on the package?

          I run 20w50 in the GS and the thickest mobil 1 goo I can find in the SV.

            That is a question I have raised elsewhere. No answer yet, I will post when I find out. Stay tuned!

              Look at the starburst on the back with the API rating.

              On the lower half it will say energy conserving.

                Ain't dat what aye sed?
                Don't use de "energy conserving" oils.

                BUT-the question is, will these 10-40 oils with the friction modifiers be labeled as being energy conserving due to the viscosity?
                If they aren't, there will be a lot of clutch failures.
