Sta-Bil Fuel Stabilizer keeps your fuel fresh for quick starts after storage and throughout the year. It effectively prevents fuel deterioration, which typically begins after 60 days, and stops the formation of gum and varnish that can harm your engine. This stabilizer also acts as a corrosion inhibitor to prevent rust and protects the entire fuel system during storage. It helps maintain cleanliness in the carburetor, fuel injectors, and fuel lines, eliminating the need to drain fuel. Available in sizes tailored to your specific needs, the twin-neck bottle design allows for quick and convenient measurement and dispensing of both large and small amounts. When used as directed, Sta-Bil stabilizes fresh fuel and protects your engine’s fuel system for up to 15 months. For results, treat fresh fuel promptly after opening the container, which has a shelf life of 2 years. Model Number: 22214
