New Concentrated Formula Briggs and Stratton Advanced Fuel Treatment

The World's Leading Small Engine Manufacturer Introduces Formula for Protection Up to Three Years

MILWAUKEE, WI (October 25, 2012) - Briggs & Stratton Corporation has introduced a new concentrated version of its Advanced Fuel Treatment, providing outdoor power equipment owners with an even more affordable formula to protect small engines against the potentially damaging effects of ethanol-blended fuels.

The new concentrated formula of Briggs & Stratton® Advanced Fuel Treatment protects any gas engine, including 2-cycle engines that use a blend of oil and gasoline, for up to three years – especially important in gas engines used only periodically, such as string trimmers and chain saws. Advanced Fuel Treatment is aimed at stopping the harmful effects associated especially with ethanol blends that account for nearly 90 percent of all fuel sold in the U.S., according to the Renewable Fuels Association. Ethanol-blended gas begins to deteriorate almost the moment it is pumped, and can break down in the fuel tank causing rust, corrosion, gum/varnish build-up and ultimately engine damage.

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.

How big is the ethanol blended fuel issue?

“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 Fuel Treatment 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.

The Advanced Fuel Treatment is available in a .5 ounce pouch and 4, 8 and 16 ounce plastic bottles. The .5 pounce pouch treats 2.5 gallons of gas; the 4oz. bottle treats up to 10 gallons of gas; the 8 oz. treats up to 40 gallons of gas; the 16 oz. treats up to 80 gallons of gas. The new concentrated formula bottles will also include markings on the bottle itself to help owners measure the proper amount of Advanced Fuel Treatment for their outdoor power equipment.

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.
