    Gentlemen (Ladies?),
    The final word on oil for the wethead can be found in the GSpot FAQ.
    it was discussed at length (surprise?) a few weeks ago, and consensus was found to be:

    API SL JASO MA2, 5w-40 synthetic (all temperature ranges).

    Note that the wethead has, as a first, a wet clutch. Do not use JASO MB or "normal" car or truck engine oil.

    As opposed to all earlier models, there are no termperature-ranges where you can play
    with different viscosities, and the word dino does not appear anywhere.

    That is expensive oil and might be hard to find on a trip.
    $60/$80 oil changes?

    Maybe BMW got fed up with people filling, say 20-50 in summer, forgetting about it,
    and getting all sort of problems when they (try) to go for a ride in freezing.

    Regardless of reason, the non-public information I have seen consistently says synth 5w-40, and no alternatives
    have been indicated.

    No, normal synthetic will have your wet clutch slipping. You should not use it.

    Linky to the discussion please. I cannot find it. I plan to use Rotella T6 synthetic which is JASO MA unless somebody talks me out of it.

    I and a bunch of KGT guys with the wet clutches are running the Rotella Synthetic 5w40 in our bikes with no issues what so ever. Good stuff and readily available for around $ 20 a gallon.

    Don't understand... what do you mean by normal?

    As, normal motorcycle synthetic will not make your wet clutch slip.

    I think he is saying that the Wethead has a wet clutch which does require oil designed for it, not just regular car oil. unlike the earlier bikes with a dry clutch which can use regular car oil.

    Excellent find, thanks.
    I usually wait for Cycle Gear to have a 4 for the price of three sale. Amazon is about a buck less / quart and saves me a 55 mile trip to the Cycle Gear. This has been great oil meeting all the BMW specs. With the new GSW oil takes a beating with the wet clutch and and gearbox shearing action. Much different requirement than the oilhead engine oil.

    or you can get this is what ever weight you need

    I would much more trust RP than Castor (from 40 yrs of experience wrenching)

    I bet if JVB would test this and say it is good EVERYONE would use it!

    one can find RP at any o'reilly store and many auto zones. You can also find a distributor. I buy mine for about $8.00/ qt
