AMSOIL Gasoline Stabilizer (AST)

It is difficult to drain all of the fuel from equipment before storage, and doing so would expose the system to other problems, including the formation of rust and corrosion on the bare metal in the tank and fuel system and the drying and cracking of gaskets and seals. Some fuels are pre-treated with oxidation inhibitors that allow them to be stored for short periods without forming excessive deposits, while other fuels have no inhibitors at all.

AMSOIL Gasoline Stabilizer (AST) reduces the oxidation process that occurs when fuel is stored for extended periods, improving performance, extending equipment life and decreasing maintenance expenses.

Two- and four-stroke recreational vehicles, hand-held power equipment, small engines, construction and farm equipment are commonly operated seasonally or infrequently, then stored for long periods of time. During these periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapor can form condensate within the engine. When this condensate comes into direct contact with steel and iron components, it forms surface corrosion on cylinder liners, piston rings, anti-friction bearings and steel/iron contact surfaces on rotational seals. Long periods of storage can also dry out cylinders, often resulting in permanent damage when the equipment is taken out of storage and dry started. In addition, fuel within stored equipment tends to oxidize and form varnish and sludge deposits that clog injectors, fuel lines and carburetors, stick floats and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life.

1-oz. of AMSOIL Gasoline Stabilizer treats 2.5 gallons of fuel.
