What's the best oil for '93 Polaris Trailboss 250? I'm currently using synthetic based oil, but my dealer recommends mineral based oil, he says he's using it for all the ATVs he's fixing. So, can I use mineral based oil or should I stick to the synthetic based which cost double?
P.S. - I have Wiseco piston in this TB's engine if it makes a difference.
