well Lizard. if you can see the type of bike that i have. I'm not into the race seen. and amsoil is a really good oil. for as hard that i ride mine, and as well it runs. its a 9100 redline cruiser. and I hit that rev limmiter all the time. I can go and just change my oil every 5,000 miles. I would have to say that its pretty damn good.
