    Question 2011 R1200GS - only mineral oil allowed, ever?

    Today, a BMW Master Mechanic told me that you can never use semi-synthetic or full synthetic oil in a Boxer engine, because, if you do, the engine will leak oil because the synthetic oils will damage the seals, and, you will also have oil consumption\burning problems.

    I understand staying away from synthetic oils until the engine is broken in so that the rings will seat properly...but, to say that you can never use synthetic oils seemed strange...

    Any insight or comments would be appreciated.

    Thanks,

    Run syns;

    As long as you can afford it! Fine products, syns in lube concerns, just expensive and to what end? My equally fine, imo, regular oil has me riding as many miles as anybody and engines equally happy to serve me. Such an old item too, OIL and the topic is weary. As I grow older, I find my dollars keep me much happier in my pocket for other adventures, like riding further, therefore the most expensive syns in engine are not on my shopping list. Randy

    Funny. My factory-trained BMW mechanic told me to use nothing but Mobil 1 15/50 in both airheads and oilheads.



    Duh. Then I realize I'm in the Hexheads/Camheads forum!
    No clue what my guy would recommend for them since I've never owned one.

    Never mind, move along, nothing to see here.

    And you trust this "master mechanic" to care for your bike? I wouldn't bring this guy my old lawn mower. He's uninformed and trying to make you the same.

    Thanks for the feedback, which is reassuring that I have not compromised my bike by using synthetic oils.

    A bit more background on my bike...

    I now have about 44,000 km on my bike. I ran dino oil for the first 30,000 km, put in semi-synthetic at 30,000 k, and put in full synthetic at about 36000 km. The bike used some oil when it was new, which I think is normal until the rings seat. It hasn't used any oil at all since I put in full synthetic about 8000 km ago, and the engine seems to be working perfectly without any leaks. So, it putting in the semi-synthetic and the full synthetic doesn't seem to have harmed it.

    I am not going to name the mechanic (who hasn't done any work for me) but whose comment would certainly give me pause.


    Thanks,

    Maybe he meant to say using synthetic will have a negative affect on your wallet.
