Protect Your Small Engines Against Ethanol

Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer is the latest in fuel additive innovation, which aims to stop the harmful effects associated especially with ethanol blends, which account for nearly 90% of all fuel sold in the U.S. Ethanol-blended gas is especially prone to deterioration, leading to rust in the fuel tank, corrosion, gum build-up, and even severe engine damage. This is reflected in performance, yielding starting issues and rough running. Here's why:

Ethanol-based fuels attract moisture, which eventually separates from the fuel

A layer of ethanol-enriched water forms at the bottom of the tank, which is highly corrosive for engine parts

Gum and varnish forms as the fuel breaks down, resulting in stuck intake valves, clogged fuel lines and carburetor jets

Fuel can go stale in 30 days or less

Briggs & Stratton® Advanced Fuel Treatment & Stabilizer also guards against octane loss due to ethanol separation, protecting your engine against pre-ignition and other low-octane events.


Benefits of Fuel Stabilizer for Small Engines


  • Lawn Mower Fuel Stabilizer
  • Protect Engines Against Ethanol Triple Antioxidant 
  • Dual corrosion inhibitors guard metal engine parts against corrosion
  • Metal De-Activator stops chemical reactions caused by dissolved metals in fuel
  • Detergent ingredients prevent gum and varnish build-up on engine parts
  • Water Protection inhibitors protect against the harmful effects of water in fuel due to ethanol
  • The Super Concentrated Formula is available in a family of .5 oz. pouch, 4, 8 and 16 fl. oz. bottles.


Briggs & Stratton Advanced Fuel Treatment & Stabilizer maintains small engine health by maintaining fuel quality, and it keeps fuel fresh for up to 36 months—well into next season. Add the Briggs and Stratton’s advanced fuel treatment and stabilizer according to package directions and then run the engine for a few minutes to circulate the solution through the carburetor.

The Advanced Formula Fuel Treatment & Stabilizer fights the harmful effects of water separation. This fuel additive contains corrosion inhibitors that form a protective barrier on metal parts to prevent rust. Detergents help prevent gummy build-up on engine parts. A metal deactivator works to stop the aggressive chemical reactions caused by dissolved metal ions in the fuel. The net result: powerful protection for America’s favorite small engines.

The right fuel treatment. From the engine experts.
