Yup. We can type posts all day about fuel, but this is more than a fuel issue. I suspect that it's a combination of factors. I can't remember if anyone posted the notice yet, so I pasted it below. They clearly mentioned "degraded fuel" and extended storage so that is a part of the mystery, but something about specific Polaris snowmobiles compounds the problem and makes it potentially explosive. Time will tell.Have not used eth forever. If it was fuel related, why only Polaris? Something bigger than just old fuel.
