About the STA-BIL 22207 Fuel Stabilizer, 16 oz (Case of 12)

STA-BIL Storage Fuel Stabilizer keeps fuel fresh during storage so engines start quickly and easily afterward. It removes water to prevent corrosion and cleans carburetors and fuel injectors. It also protects the engine from gum, varnish, rust and corrosion. Treating the fuel before storage means you don't need to drain the tank of a 2-cycle or 4-cycle engine.

Use it in any gasoline-powered vehicle or equipment you plan to store for 30 days or longer. It keeps fuel fresh for up to 24 months and works in all gasoline blends, including ethanol-blended fuel up to E-85. It does not contain alcohol. It can be used in cars, motorcycles, small engines, generators, lawn mowers, snow blowers and boats.

Add 1 ounce (30 mL) for every 2½ gallons (9.5 L) of fuel. Use it only with fresh fuel, and keep the gas can or tank 95% full to prevent condensation during storage. After adding it, run the engine for 5 minutes to treat the whole fuel system. Made in the U.S.A.
