About Sta Bil Marine Treatment

For everyday in-season engine performance improvement and protection, use 1 ounce in every 10 gallons; for seasonal storage and for fuel system clean-up, use 1 ounce for every 5 gallons.

Sta-Bil® Marine Formula may also be used with 2- and 4-cycle gasoline engines.


For best results, the fuel tank should be filled 95% with fresh fuel. If possible, add Sta Bil before filling the tank, to ensure mixing of the additive. Run engine for 5 minutes to ensure treated fuel makes its way to the carburetor or fuel injectors.


Always wear skin and eye protection when using this product. Use in a well-ventilated area. Keep away from open flame and spark. Seal bottle tightly when storing. Store in a cool dry place out of direct sunlight
