Use CRC gasoline fuel stabilizer to protect all 2 and 4 stroke engines. It keeps fuel fresh during storage, protects against corrosion, prevents gum and resin build-up, keeps filters and injectors clean, and is non staining. As Ethanol blended fuels become more widely used, CRC fuel stabilizer will become an even more popular additive by virtue of its ability to prevent fuel separation caused by gasoline containing Ethanol.
