My father has had to replace a fuel tank and carburetor in his cabin cruiser boat since the greenies started screwing with the gas that you can buy in the US. It has become a real issue for boat owners. Basically, almost all US gas now contains 10% ethanol. In engines and tanks that sit still a lot and also run lower temps (like boats) the ethanol starts to separate from the gas. Also, there is water in all ethanol and once separated, this can cause issues too. My dad is using an enzyme treament in every fill-up now to hopefully deal with the ethanol & water. Also, I know there are gas stations near lakes that only carry non-ethanol gas, but I hate to have to drive 30 minutes to the nearest lake everytime I fill up. Has anyone heard about what this crap does to motorcycles? If anything?
