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.

• Suitable for all gasoline-powered equipment.
• Keeps fuel from deteriorating during storage, allowing easier start-ups.
• Prevents the formation of varnish and gum in fuel systems and storage tanks.
• Ideal for all two- and four-cycle engines including motorcycles, snowmobiles, boats, ATV's, tillers, mowers, car, trucks, snow-blowers, chainsaws, generators and more.

During periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapour 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.

Treat rate is one ounce with every 2.5 US gallons (9.5L) of fuel. One bottle treats 40 US gallons (150L). Run engine with treated fuel for 4 to 5 minutes.

During extended storage, also use AMSOIL Engine Fogging Oil to prevent internal engine component rust and corrosion. This two-step process will ensure post-storage start-up and extend equipment life.
