    Did my first oil change today at about 250 miles.Dont know what kind or what weight was in it but now its got Rotella T 15-40.I did a hard break in on the engine,for whatever its worth I have always had good luck down the road settin the rings early on.Used oil didnt look bad,guess filter did a good job of catchin most of the metal.

    Rotella 15-20 is a diesel oil. (Use it in my truck) The 950 owners manual specifically says we shouldn't use diesel oil. I think it has something to do with the fact the crankcase oil also lubes the clutch. Good luck and ride safe.

    Respectfully, I will state that the Rotella oil you are using is a very good petroleum oil and works very well with motorcycles, such as the 950, that utilize a wet clutch system. It also does NOT contain any of those nasty additives/friction modifiers that are harmful to our bikes. As long as you're happy with a dino oil and you change it at its required intervals, the Rotella you're using is a good one.

    Take care and enjoy your weekend.

    BopP,the manual states not to use a cd rated diesel oil which rotella is not.

    By the way, there are many V*1300 owners out there who also use that same Rotella. I use only a full synthetic (Amsoil), but it's also a "personal preference" and not an absolute necessity to do so.

    Interesting - I stand corrected, although I am a bit confused. Is this a different type Rotella than the diesel? I know my truck specifies it as one of the options.
    Good to learn new things.

    Hi Bob.

    There a lot more to be found, but I simply cut and pasted the following info. I apologize for it being so long, but I also wanted it to be a little better understood:

    Though marketed as an engine oil for diesel trucks, Rotella oil has found popularity with motorcyclists as well. The properties of heavy duty engine oils tend to map to the same requirements of motorcycle oils, particularly those whose engine and transmission share the same oil. (This is called a "shared sump" design, which is unlike automobiles which maintain separate oil reservoirs - one for the engine and one for the transmission). The chemical additives found in heavy duty engine oils work well with motorcycles. In addition, the lack of "friction modifiers" in truck oils such as Rotella means they do not interfere with proper wet clutch operations.

    Motorcycle specific oils tend to cost between $8 and $10 per quart. Shell Rotella T 15W-40 costs about $19 per gallon (or about $5.95/quart). The price economy of Shell Rotella T allows a motorcycle owner to change oil more frequently...

    One standard, JASO-MA, specifies a set of characteristics an oil must meet to be certified by JASO. It includes such things as the amount of sulfated ash, the foaming tendency, and the degree of friction provided by the oil.

    The friction test is what is of particular interest to motorcycles. An oil that provides too little friction has a tendency to allow wet clutches -- those bathed in the engine oil -- to slip. An oil that demonstrates too much friction does not provide the lubricity needed. The JASO-MA test specifies a range of friction the oil must fall within to meet the specification.

    The new Rotella T CJ-4 15W-40 and 5W-40 packaging does not officially state compliance with JASO-MA.

    However, posts in various motorcycle-related forums cite e-mail confirmation from Shell that Rotella 15W-40 and 5W-40 CJ-4 has been tested and shown to meet the JASO-MA friction test. The belief is that the new CJ-4 oil does in fact meet JASO-MA, but the packaging does not carry the certification, nor does Shell advertise it as complying with JASO-MA.

    Testimonies from many motorcyclists on different forums confirm the applicability of Shell Rotella T as effective for motorcycles. Numerous "Used Oil Analysis" (UOA) on show acceptable wear metal numbers for Rotella T in motorcycles for oil change intervals from 1000 miles all the way to 8000 miles.

    Enjoy your weekend.

    One of the reasons I use rotella is because all of my vehicles are diesel and non synthetic rotella goes for around 7 to 10 dollars a gallon versus 19 for synthetic.I probably will go to synthetic my next change but for now regular dino oil.I am from the old school and tend to want a few more miles on my ride.I did a little research and found quiet a few bikers use rotella.

    Interesting stuff. Thanks much.
