    Search for it on https://bobistheoilguy.com/, or the JASO link provided in the first post.

    Upon further consideration, I think I will continue using Rotella in the XJs. The Kirkland is fine for the cars, but I don't feel like taking chances with the XJs.

    Except.... I might try Rotella T6 Synthetic. You know, for science.

    I'm a big fan of the Rotella oils. I use the 15w-40 T4 in the older bikes with short change intervals, and the 5w-40 T6 in the newer bikes with longer change intervals.

    without the jaso rating on the jug it may not be suitable for wet clutches. it is not worth the risk of your clutches slipping
    diesel oil main thing is it can not be used in motors with catilic converters or it will ruin them

    Yep, that's it. Notice on the back it says JASO MA/MA2.
