Product Highlights View Full Description

Reduces the oxidation process that occurs when fuel is stored for extended periods to prevent the formation of varnish and sludge which can clog injectors, stick floats and cause poor engine performance. Ideal for stored seasonal equipment such as snowmobiles, lawnmowers, motorcycles and boats.

For maximum convenience and cost-effectiveness, equipment and vehicles used seasonally, such as motorcycles, snowmobiles, personal watercraft, snowblowers, outboard motors and classic cars, need to start easily and run properly when removed from storage. Gasoline, however, is not formulated for long-term storage and can start to degrade in as little as 30 days. Degraded fuel leads to varnish and sludge that clog injectors, fuel lines and carburetors; stick floats; and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life.

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

Delivers Confidence
Treating fuel with AMSOIL Gasoline Stabilizer prior to storing equipment provides confidence. It offers peace of mind that equipment will not only start when it is needed, but will also perform properly.

Eliminates Need to Drain Fuel
Draining fuel from equipment can not only be difficult, it invites corrosion on the bare metal in the tank and 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 eliminates the need to drain fuel from equipment before long-term storage. It fights fuel deterioration, severely limiting the formation of damaging varnish and deposits to help extend equipment life.

Decreases Maintenance
Deposits, varnish and sludge that form from degraded fuel can cause important components in the fuel system to become clogged or stuck and require thorough cleaning or replacement. AMSOIL Gasoline Stabilizer helps reduce maintenance time and costs by preventing harmful deposits from forming in the tank and fuel system, eliminating the need to clean or replace carburetors after long-term storage.

  • Helps keep fuel from deteriorating
  • Protects against varnish and gum buildup
  • Fights ethanol corrosion

APPLICATIONS
AMSOIL Gasoline Stabilizer is engineered for use in, but not limited to, motorcycles, snowmobiles, ATVs, UTVs, outboard motors, stern-drive and inboard marine engines, personal watercraft, lawn equipment, chainsaws, snowblowers, portable generators, handheld power equipment, motor scooters, powered farm equipment, powered construction equipment, cars and trucks.

Dosage recommendation
One ounce of AMSOIL Gasoline Stabilizer treats 2.5 gallons of fuel, including fuel that contains up to 10 percent ethanol.

Before storing equipment, treat it with the appropriate dose of AMSOIL Gasoline Stabilizer. Let the engine run for five to 10 minutes to thoroughly circulate the additive through the fuel system. Stop the engine and store the equipment in a dry, covered location.

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.

    Comments about Gasoline Stabilizer:

    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.

    HIGH QUALITY FUEL SYSTEM AND COMBUSTION CHAMBER CLEANER

    By 

    from Dumas, Texas

    Verified Buyer

    Comments about P.i. Performance Improver Gasoline Additive:

    I recommend AMSOIL p.I. cleaner to anyone to clean the engine combustion chamber and fuel injectors or carburetor of a gasoline engine. I've used this exact product on a recommended vehicle maintenance schedule for many years. There is a very noticeable difference to prevent engine from knocking by cleaning the carbon from the combustion chamber. I use this in a Ford truck, Pontiac car and a Kawasaki motorcycle. Highly recommended above any product of its kind is AMSOIL p.I.

    Before I started using this product (P.I.) my 2006 Toyota Tacome was getting about 19 - 20 MPG. When I use this product it moves easily to 20-22 MPH. It must be doing something good. However, I must admit to using exclusively Amsoil Signature oil.
