    oil consumption on 1150rs

    Just got an '02 1150 rs with 12k on the clock and did an oil change @ 12,600. 800 miles later and I'm having to add about 300cc of oil to top off. Is this normal for an oilhead to "use" oil or have I got a problem? I did the 5 min on the side stand then checked oil level on the centerstand.

    Oil heads aren't broken in until 20000 miles. Quit obsessing.

    Top off to what mark? If you are filling to the top of the sight glass you are most likely overfilling. Aim for the dot in the center and see if you oil level stabilizes.

    It seems like a lot. You probably did this, but just to be sure, was your motorcycle engine hot from riding when you went parked it using the sidestand? With my 1150 I have to park it hot on the sidestand, let it sit for about 10 minutes, then onto the centerstand for several minutes. At that point I feel I get an accurate, consistent oil level.

    Interestingly if I run it on the centerstand after that procedure and shut it off, there is no oil in the sight glass even if I wait overnight.

    Bottom line is yes, MOST 1100 and 1150's use some oil. Search the forum and you will find several discussions. And I agree, the more miles the less they use, but they almost all burn some.

    my bike

    as reference on this thread, 180K miles, 20w50 V-Twin Mobil, uses 1 qt in a 5000 mile oil-change cycle.

    Some of the engines have a certain "comfort point" in oil level. They will blow off any amount over a particular point. If you keep refilling to the absolute full mark it will keep blowing it out. Try an experiment and allow it to drop a tad. As long as it is above the bottom of the circle in the sight glass you are OK. See if it stabilizes at a level below full.

    All above is good advice.

    I've also noticed that consumption is remarkably less when doing distance instead of in-town riding. Doesn't matter how I ride - hard acceleration or slow, sustained high-speed or just poodling along - my bike consumes more oil in town. Having said that, on a 5,000 km 20% over the speed limit tour, I used about 1/2 liter of oil whose name and grade shall remain nameless.

    This is the right way to check the oil. If you do it in any other sequence you will get an inaccurate reading.

    In 6000 miles my R1100 oilhead would use about 300cc of 20-50 synthetic oil.

    It took my 02 R1150RS amost 40K for oil consumption to stabilize.

    If I put in any above the center line it burns off quick.

    Short trips it will burn some. Take off on a trip and will use very very little if any.

    And for winter I use Rotella 5W40 Syn. Starts up like summer.

    As always, I'm curious how anyone would know their oil consumption this accurately, I quote, "In 6000 miles my R1100 oilhead would use about 300cc of 20-50 synthetic oil." 300cc would be aproximatley half the height in the oil level view window.

    I agree that an Oilhead with miles on it above 20,000 will certainly stabilize oil use.
    My 94 RS has high miles on it, yet uses very little oil. I go about 5,000 miles between oil changes and I may add about 1/2 quart, maybe, in that time before the next change. On the Oilhead oil sight glass, the distance from the bottom of the view port to the top, with the bike level on the centerstand is about one pint of oil, or about 473ml, which is also equal to 473 cc. So from the bottom or top of the window to the center dot is 236 to 237cc. Not enough to worry about as that much oil is easily held up in the cooler and oil lines. So its good to monitor the oil level, but don't obsess about it, just ride more.

    Why do they all do that?

    Since we have another oil thread going anyway I've always wondered why Oilheads use oil in the first place. I know over filled oilheads will blow out the excess due to crank case pressure but if they are filled correctly, where does the oil go? Just curious...

    The reason I know is that I carried a 1/2 liter bottle of 20-50 oil with me and in a 6000 mile ride I only had to add slightly over half of the bottle or 300 cc to bring the oil level up to full.

    I know my oil consumption exactly every litre in the last 236,000 km
    This also applies to Gasoline, Tires and Brake Pads & rotors
    Easy to track on an Excel spread sheet.

    Bottom line:
    Lots of highway - very low
    City riding with lots of heat cycles - 2 to 3 times the oil use
    Synthetic burns off less than Dino juice
    Oil consumption tends to increase as the oil ages
    Running from center of sight glass to bottom burns less than top to center.

    Your results may vary.

    It's all about the details.
