    I always need to convert it back to Merican...

    2cm = 3/4" (really .787").... Ahhh that's a bit much...

    The dealer's have been known to fill to the high side but I doubt it's 3/4" over the full mark...

    The problem will be windage and the crank hitting the oil causing the oil to get whipped to whip cream....so to speak.... When that happens the oil pump will no longer be pumping a liquid but an air entrained froth.... Not a good thing to happen.... Bearings are supported with a layer of oil not oil and air....

    Suggest you drain some out....

    I was going to say your Mini will burn that oil in no time but after MM converted it to Merkian I would also say drain some. Thanks a little too much extra.
