I have read a few threads about the griz using oil, I know mine does, has since I bought it, 4300 miles on it now and it hasn't gotten any worse, but it hasn't gotten any better either, still uses some oil, not a lot but I am not use to having to add oil to the other machines that I have had. Starts good and runs good, never have had the engine temp. light come on so it hasn't been run hot, anybody else have this same thing, is it a characteristic of the griz?
