Product Description
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.

Use it for the winter in my fuel to treat all my lawn/driveway equipment (mowers, blowers, snow blowers, line trimmers). Also use it on my Yamaha FJR 1300 motorcycle and I have not had any problems.

The reason why I am not going to purshas this product again is because of the lack of directions pertaining to the amount of liquid to use per gallon of gasoline.

Big Help after Prolonged Idle Times!

Great Product to use for any time length in out of operation power equipment. I use it in all of my lawn mowers, snow blowers, yard tractor and motorcycles. With the amount of changing fuel mixes and alcohol in gasoline here it helps to keep the fuel in a steady mix without the separation common here after short times. Almost always, my power equipment, will start with one, two, or three pulls, even after sitting idle for 3-5 months. The equipment will run normally. I will usually add some into my gas cans with each fill.

A must for living in a remote location...

I trust Amsoil products, after using them for so many years. Our gasoline gets delivered by barge and then trucked to us. It's always got visible crud in it and I have to put it through a filter first. As soon as I get my gasoline, I filter it and add Amsoil Gasoline Stabilizer. While others in the area have had numerous problems with 'bad gas,' my gasoline has never let me down. It gets used in my Stihl saws, Echo yard equipment, my Polaris Ranger, my portable Honda generator, my Ariens wood splitter, etc. Never a problem.

Winter storage of my 2014 BMW motorcycle

Living in Washington State, I don't ride my 2014 BMW R1200RT-LC year round so I leave it in the garage hooked up to a Battery Tender, and the gas tank filled with Pure Gas AND 3 oz. of Amsoil's Gasoline Stabilizer. Every summer when I start up my bike there is little hesitation, and the engine settles down to a steady idle. Riding that first tank shows no problems or misses in any RPM range, though I don't get the full mileage of 300 miles, but with the very next tank of gas things are back to normal.
