Hi I have just bought a Jet ski a month ago. I just bought some more 2 stroke oil from a jet ski shop. They recommanded it but they said It might not mix with the other brand in there which im not sure what was in there before. I cant get in contact with the old owner to find out. What do you recommand to do? I got about a quater of oil left Do you think just mix it in or somehow drain it you got any instruction on how to do that?
Thanks very much
