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.
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.*
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
*Based upon independent testing of AMSOIL Gasoline Stabilizer obtained Nov. 8, 2018 and Sea Foam Motor Treatment purchased Oct. 25, 2018 in a modified NACE TM0172 using synthetic sea water per ASTM D665 part B.
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.
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.

Switched to this from StabilBy  KEVIN,  a  Verified Buyer  from  Salem Illinois  on  January 21, 2021Have always used Stabil and decided to give this stuff a try. It has proven to be my new go to and the price has been something a live with.
It helps my seasonal equipment to run better over their off season.
Great for winterizingBy  GLEN,  a  Verified Buyer  from  Northern New Mexico  on  December 25, 2020Living at 7500 feet in the mountains requires winterizing the motorcycles and dune buggies. Once I started using the Amsoil gas stabilizer startup in the spring with the snow melts is no problem. I've used other brands that keep the gas smelling good but when it comes to starting, well often it's not that quick. With the Amsoil stabilizer, the bikes start right up even after sitting for several months.
As advertisedHave used this product in cars which it in storage for months at a time. Since switching, I have never had any issues with varnish or sludge. Even the finicky floats on a Rochester carb work after extended periods of no use.
No issue after a cold winterMy equipment gets minimal use in winter. So far I have had no issues with winter starts or spring start up. Fuel in cans are still fresh as well.
good for stored car.
