There is not such thing as Kawasaki oil, or any other auto or motorcycle manufacturers's. They are not in the business of making oil, gasoline, or any other chemical product. ...they buy from oil (or other chemical) manufacturers, like anybody else, and put their brand label on it charging for it. Last I knew, USA Kawasaki was buying 'their' oil from Motul. Not disrespect,..... all the manufacturers do same thing....and I'd do it too if a I was one of them.
