When/if you do go down that rabbit hole of all things oil, you will see that the formulations for car vs motorcycles isn't the same. Rotella "diesel oil" has a good/decent package for motorcycles, but for me I am pretty keen on the motorcycle specific TRUE PAO ester synthetics from Motul and Maxima, with my back up being Mobil 1 4T. Wear and shearing aside, I just notice better overall shifting and less mechanical engine noise with these premium motorcycle oils. I change about every 5K to 6K anyways, and I feel that all these popular increased mileage intervals are inherently not the best idea.
