When I bought my 1st dirtbike I heard of Amsoil. I did some research on the company and gave it a try. Been using it in everything I own, ever since. I recommend Amsoil to evetmyone I know. I enjoy the courtesy kit with every order. A funnel, gloves, Amsoil sticker, and a oil change reminder window sticker. Best oil on the market, hands down. Keep doin what you do Amsoil!
Bottom Line
Yes, I would recommend this to a friend.
