STA-BIL Storage is a gasoline additive that keeps fuel fresh for up to 24 months in stored engines. It removes water, cleans carburetors and injectors, and guards against gum, varnish, rust and corrosion, so you skip draining the tank. One ounce treats 2.5 gallons, and it works in ethanol blends up to E-85. Owners rate it highly for reliable spring starts in mowers, generators and boats; rivals like Sea Foam and Lucas do similar jobs, but STA-BIL is the name most small-engine owners reach for.

Owners give it very high marks, mostly for equipment that starts easily after months of storage. Many use it every season in mowers, generators and boats and report no gum or varnish problems.
STA-BIL Storage Fuel Stabilizer keeps fuel fresh during storage so engines start 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. Treated fuel stays fresh for up to 24 months, so there is no need to drain the tank before storage.
Use it in any gasoline-powered vehicle or equipment you plan to store for 30 days or longer. It works in all gasoline blends, including ethanol-blended fuel up to E-85, and in 2-cycle and 4-cycle engines. It does not contain alcohol. This case includes twelve 10 oz bottles.
Add 1 ounce (30 milliliters) for every 2½ gallons (9.5 liters) of fuel. Use it only with fresh fuel. Keep the gas can or tank 95% full to avoid condensation during storage. After adding it, run the engine for 5 minutes to treat the entire fuel system.
