Ethanol gas proports to reduce air pollution; but it’s not without side effects. Gas mileage goes down by about 3-4%. Ethanol is hygroscopic which means it attracts water and can lead to corrosion and water-fuel phase separation over time can damage rubber seals or create gum deposits.

Therefore, it’s recommended that equipment with small engines, motorcycles, classic cars, and especially watercraft should use non-ethanol gas. But where to find it?

Pure-gas.com lets you look up stations in just about any state that sells ethanol free gas. Be ready to pay for it though – usually $0.20-$1 more per gallon.
