    Unhappy Put in too much oil...what to do?

    Recently changed the oil and put in about a quarter quart too much. Can I leave it or should I take some oil out? If I should take some out what is the easiest way?

    Thanks as always for your advice.

    Happens...you are not the first to ask. Some folks remove the filter and drain some there, may take a few times with filter method. Others drain out and refill.

    If you have run the bike, check the drain on rear of airbox,shifter side as it may collect there as well.

    1/4 quart is not a catastrophic overfill...is it past the sight glass?

    So you changed the filter, and actually poured in four complete quarts. And then, poured in another 1/4 quart? Why not just stop at four since the oil capacity is just about four quarts anyway.

    I wouldn't worry about it too much. But if it makes you feel better drain off a bit of oil. Loosen the drain plug till it starts to dribble oil out (don't take the plug out), and let it drain down to the center of the sight glass.

    Funny, that happened to me the other day, for some reason I thought I needed 4.75 quarts instead of 3.75. Just drained some from the plug and re-filled until correct. The crush ring is still okay - no leaks. Same bike as yours

    As asked above, over the sight glass? 1/4th qt is not a big deal. I'd say even if it is currently over the top of the glass take it for a ride or two and see if it settles. If you didn't pour more than 4 total qts in, you're doing ok.

    With the new oil not being dirty to darken the sight glass I was unsure that I had put enough new oil in so I am now over the sight glass. I will drain from the filter to lessen the oil.

    Thanks for the advice.

    Too high an oil level will cause increased crankcase pressure which results in oil sight glasses blowing out.
    I think BMW even issued a bulletin to that effect.
    The excess should be removed and the level should be run from mid glass to the bottom.

    It's all about the details.

    Have to be WAY high, like forgetting to drain the old before adding new, IMHO. A cup or two over, I wouldn't worry about.,

    I've put in too much on a couple of vehicles in the last 40+ years -- and always drain the extra.

    Instead of draining from the filter, it'll be a lot easier and less messy just to loosen the drain plug to allow it to seep down while watching the sight glass.

    Yes, too much oil in the crankcase WILL cause high case pressure and could cause oil to blow by the seals. From the center of the sight glass to the top is about a pint of oil.

    I doubt an extra pint would be enough to cause excessive crankcase pressure.

    I've got an '03 1100S and, according the manual, it says to fill to the top of the red line in the sight glass which is about 1/8" away from completely covering the glass. I've run it this way for 40k km (25k miles) in hot weather and cold and all seems well.

    Should I be dropping the level?

    This oil level thing comes up often. I don't think running at the MIN or MAX level is wrong, it's just not optimal. The middle is just right.

    This is from the factory manual:
    Caution: NEVER add engine oil above the MAX mark.
    X Tightening torque:
    Oil filter............................................ ............. 11 Nm
    Oil drain plug.............................................. .. 32 Nm
    Fill quantity for engine:
    - with oil filter change .............3.75 l (6.6 Imp. pints)
    - without oil filter change ........3.50 l (6.2 Imp. pints)
    Oil volume between
    MIN and MAX marks ............0.50 l (0.88 Imp. pints)
    Engine oil grade:
    Brand-name HD oil for four-stroke spark-ignition en-
    gine, API classifications SE,SF,SG; combination
    with CC or CD specification.

    Sight Glass

    I did the same thing on this gorgeous 57 degree day here on Long Island, sunny skies, organizing the garage kind of day...

    Got a '04 R1150RT from a local guy in August.

    He told me repeatedly, that the 1150 RT engine 'Hides Oil really well!

    Three times, before we signed papers, he repeated to me the above.

    So, upon adding my third quart, I realized that the new oil went right up to the top 'max' mark on the sight glass, and then thought... 'Oh sh*t', too much oil'.

    I drained the oil down about 3/4 quart through the bottom drain plug, and then
    let the glass settle.

    I added some oil about 1 cup at a time. Stopped, started the bike up, let it settle, and added only another cup, and visibly saw signs of the oil on the 'minimum' mark of the sight glass, and then, stopped there.

    Has anyone else heard this theory about the RT 'Hiding Oil Really Well' and forwarned about not adding 'too much oil', even though the owners' manual and other service manuals say 'fill to max level'?

    Oh no... I think I started yet a third thread off of this RT oil question.

    Ride Safe!
