Extended Seasonal Gasoline Storage
Helps keep fuel fresh for up to 12 months. Fights oxidation to prevent the formation of varnish and sludge and keep floats and injectors clean for optimal engine performance. Ideal for stored seasonal equipment such as snowmobiles, lawnmowers, motorcycles and boats. Eases starting process when equipment is taken out of storage.
Too often we forget to treat the fuel as we put away our toys and equipment. Poor performance is too common now with fuel which degrades faster than ever. Don’t take chances! I personally have regretted not using this in the past in a vintage motorcycle, new weed-eaters and projects I’m working on which don’t get started as frequently as they should.
Pay now or pay more later!!
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.Check Price or Buy

AMSOIL Gasoline Stabilizer provides corrosion protection Sea Foam can’t match, helping maintain power and performance and keeping metal looking like new even when subjected to salt water.*
AMSOIL provides fuel stability that Sea Foam Motor Treatment® can’t match, helping maintain startability and protect against the formation of varnish and gum.Z
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.
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
