New Briggs and Stratton Advanced Formula Fuel Treatment and Stabilizer

New Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer Protects Small Engines from Ethanol-Blended Fuels

Proprietary Formula Protects for Up to Three Years

MILWAUKEE (October 2011) –  Briggs & Stratton Corporation has developed a potent new fuel preservative that keeps ethanol-formulated gas fresh in the tank for up to three years.  Called Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer, the product provides an easy and inexpensive solution to protect small gas engines from ethanol’s potentially damaging effects. 

The fuel treatment protects any gasoline against chemical breakdown, but is targeted at ethanol-blended fuels.  There’s practically no escaping the use of ethanol-based fuel:  At the end of 2010, nearly 90 percent of all fuel sold in the U.S. was blended with ethanol, according to statistics from the Renewable Fuels Association.

Protecting engines from ethanol-blended gasoline is especially important in equipment that is used intermittently or infrequently, such as lawn mowers, generators, outboard motors and recreational vehicles.  The longer these blended fuels sit in the fuel tank, the more damage they can do, resulting in starting issues, rough running and even severe engine damage. 

“Fuel begins degrading almost the moment you pump it,” says Eric Risse, fuel systems engineer at Briggs & Stratton Corporation.  “Ethanol-based fuels are particularly damaging because they attract moisture which eventually separates from the fuel, forming a layer of ethanol-enriched water at the bottom of the tank where it does its damage.”

Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer combines a “triple antioxidant” formula with additional ingredients to protect the entire fuel system, fighting the harmful effects of water separation.  Corrosion inhibitors form a protective barrier on metal parts to prevent rust and corrosion, while detergent ingredients help prevent gum and varnish 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:  extreme protection for small gas engines against fuel-related problems.

 “Ethanol is a real concern, so everyone has to protect their small engine applications,” says Mike Barnett, marketing manager for service parts at Briggs & Stratton.  “The Advanced Formula Fuel Treatment & Stabilizer provides the latest technology available to protect gas engines, even during long periods of storage.”

The Advanced Formula Fuel Treatment & Stabilizer is available in 4,8,16 and 32 ounce plastic bottles.  For more information on the Advanced Formula Fuel Treatment and other Briggs & Stratton service products for outdoor power equipment, visit

Note:  Briggs & Stratton emphasizes that certain gasoline blends should never be used in lawn mower engines and other small gas engines.  Do not use gasoline containing more than 10 percent ethanol, E15 or E85 gasoline, or gasoline containing other alcohol blends because they can damage the engine.  Repairs required because of the use of these unapproved gasoline blends are not covered under the Briggs & Stratton engine warranty.
