  2. I wouldn't use diesel oil in a bike. It's unlikely to do any harm, but
    it's equally unlikely to reap any measurable benefit and it costs more.

    Just use plain old semi-synth 10/40. It's not a super-high-revving
    tuned-to-hell-and-beyond sports bike for Christ's sake.

    I use Mobil Delvac 1300 15W-40, which is a very high quality oil, it
    is about $6 per US gallon (3.785 liters) at Wal-Mart. Mobil refer
    to it as their 'million mile oil'. It's not a synthetic[1], but
    I change oil in my bikes very frequently. Conventional auto oil
    sold by the quart is roughly the same price, but has dramatically
    lower levels of zinc and fewer of some other key additives compared
    to diesel oils, which do not have to conform to the requirements of
    catalytic converters on gasoline engines. I use Delvac 1300 15W-40
    in all my bikes, and *if it meets the viscosity range specified in
    your bike's owner's manual*[2], it is an excellent choice.
    Semi-synth isn't bad, nor is full synth. But in my opinion, it isn't
    worth even the small difference in price over a high quality oil like
    Delvac 1300, Chevron Delo 400 or Shell Rotella if you change often.

    I'm pretty sure one of the three diesel oils I mentioned were included
    in the latest Motorcycle Consumer News oil test (within the last year
    or so, not the first one), and compared very well with the very
    expensive bike-specific oils.

    [1] Mobil does make a Delvac 1 full synthetic diesel oil, but it's
    much harder to find and quite a bit more expensive. It's still
    probably cheaper and better than synthetic bike oil, though.

    [2] It does for all three of my bikes.

    I'm partial to AMSOIL which they backup with research. Makes my engine
    run 20 degrees cooler and I get about 2 miles more to the gallon.

    Info at:

    http://www.amsoil.com/products/streetbikes/index.htm

    I don't sell the stuff so the web site reference is only given so you
    can make an informed decision about what's best for your bike. I would
    never consider putting diesel oil in my bike. For starters it doesn't
    have all the needed additives that a bikes engine needs.

    Good information on the Q&A section even if you don't use their produce.

    Good luck!

    This is correct, It's called Shell Rotella (T?) and it comes in
    synthetic and non-synthetic.
    The synthetic version is probably the best synthetic bang for the buck
    you can get and from what I have heard a very good oil !
    yes, you can use it in the motorcycle

    Lets say the manual for a certain bike calls for e.g. SH or higher grade
    motor oil. And there are no more specific demands in the manual.

    Now, you find a reputable oil that has the required grade. Is this a
    reasonable oil to use ?

    How do you know that a certain oil does not have the needed additives.
    You don't. The only evidence here is that the oil conforms to the
    demands set by the bike manufacturer, the company that has to back
    up a warranty and has their reputation at stake. If the oil is rated for
    diesel use is neither here or there as long as it has the correct petrol
    engine grade.

    To pass the grading system, the oil needs to pass a number of tests
    that will test key performace areas. The tests show performance,
    not the precence of any "magic" component.

    As to the rediculus Amsoil reference to research, how do they
    think that their competitors develop and evaluate products ?
