    Attention all 1999 R1100R oil nerds - A very short report on oil consumption

    My 1999 R1100R now has 86k + on the clock. Last weekend (actually 4 total days) I rode to Darlington, SC for the NASCAR Sprint Cup race and then to my Mom's north of Atlanta for Mothers Day, what a good son I am .

    I rode 1,839 miles and used a total of 175 cc of oil. The bike ran outstanding! Almost every inch highway miles at an indicated 80 to 85 mph which works out to approximately 75 miles per hour. The ride home I clocked almost 725 miles in a 12 hour period.

    And, because the question will probably be asked, I am using Mobil 1 V-Twin 20/50 Synthetic as my choice of lubricant. This is a recent change for me as I have only been a Mobil 1 fan for maybe 5k miles at this point. Prior to that I was using good ol' Castrol 20/50 petroleum. There is a noticeable difference in mechanical noise with the Mobil 1 and I am extremely pleased so far.

    Please no oil wars... let's discuss proven oil consumption numbers for given miles driven might be interesting. Maybe that's already been done?

    What caused you to switch?

    Please note all of my comments refer to Mobil 1 V-Twin 20/50 Synthetic specifically.

    I have been reading so many good things about Mobil 1 through the years and I wanted to see if Mobil 1 would help with some of the mechanical noise and ultimately engine longevity. I change engine oil and filter every 2.5k but I always noticed the Castrol would turn a bit noisier somewhere around the 1k mark. This seemed to be in agreement with many of the oil articles I read as many stated petro oil would begin to break down at the 1k mark even though you could still continue to use it.

    Mobil 1 has exceeded my own expectations with respect to mechanical noise. We'll possibly see as to the longevity side of it as I may or may not keep the bike long enough. For now I am a believer.

    The points I deducted for you having attended a NASCAR race are more than compensated for by 1. You admitting it, and 2. You visiting your mom right afterwards.

    My "S" has done the LA-Vancouver-LA trip twice. A total of about 5,000 km (3,000 miles). Similar speeds to yourself with some really hot weather (100F +) thrown in for good measure. On both trips total oil usage was about 250cc. I too use Mobil 1 but its the 15-50 automotive variety. I've been using this oil (in different grades) for about 25 years in all my cars and bikes. Checking the specs between the automotive and the "V-Twin" formulation reveals very little difference so I save myself a few bucks.

    And those are my two cents.

    At the risk of losing points I have to admit I LOVE NASCAR. Exciting racing, amazing technology and a true team effort. They don't go on strike and they don't cry poverty like so many pro ball players. In addition, drugs are just about non-existant. And they actually say a real prayer prior to the race which may not be so popular today in many circles.

    I will respect NASCAR when they demonstrate an ability to go left AND right in the same race. To date, they've got nothing at all on MotoGP or even AMA.

    r1100rs takes 5W50 - are you'se guys changing viscosity?

    OK now I see where a person can substitute viscosities (sorry) but I see 5W50 goes up to over 100 deg F. so = shouldn't I stick with the lowest viscosity I can? My bike is a '94 r1100rs with almost 100 K miles and may not have been cared for excellently.

    The first number in the viscosity rating represents the viscosity at normal ambient temp (~72 degrees F maybe?).
    The purpose of oil is to provide a slippery film between moving parts.
    If the oil is too thin, it may be more likely to get squeezed out from between the surfaces instead of lubricating them. And, especially at start-up, before the oil pressure has built up and the juice is flowing, lubrication is desirable.
    The engineers who designed your engine probably have a purty good idea of what lube it needs... go with their recommendations unless you have evidence or preferences that warrant a variation.

    I've used lower viscosities during break-in, after a rebuild, and for dyno runs (ok, that's cheating!); it's also a common practice on the track, just to reduce friction losses.

    In the example of a 20W-50 oil....20 is the viscosity rating at 0 degrees Celsius and 50 is the viscosity rating at 100 degrees Celsius.

    As Paul has said, I'd stick pretty close to what the factory recommends.

    Now, I will serve my penance for responding (yet again) to an oil thread.

    Oilhead oil consumption is most during warmup. (Piston/ring clearance is significant when cold)
    Theoretically if you never shut them down they would use little or no oil.

    I have logged oil consumption for 290,000 km on my '00 R1150GS
    Up to 80,000km I had an oil slurper - OO babied it on break in.
    If you read the BMW spec's for these engines they say 1000ml/1000km is the limit, which is totally ridiculous.

    I re ringed it and broke it in hard.

    Results?
    City hwy average is 110ml/1000km or less
    My recent Alaska trip of 10,000 km over 20 days (88 km hr average speed) consumption was 60ml/1000km
    And YES, I know exactly how much I use as I have a graduated litre container and log on an excel spread sheet. ( the same applies to fuel, tires, brake pads & rotors).
    The bike has always been run on 20w50 Golden Spectro semi syn. since I bought it @ 25,000km


    Worth noting: My buddy rode a brand new 2015 GSW on this trip and his oil consumption was 0 for the same mileage.
