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.*

Improves Stability
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

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.

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.
