AMSOIL Gasoline Stabilizer

Formulated to Resist Gasoline Breakdown

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 inhibits the oxidation process that occurs when fuel is stored for extended periods, improving performance, helping extend equipment life and decreasing maintenance expenses.

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

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.

AMSOIL Improves Stability

AMSOIL Gasoline Stabilizer delivers 8X longer fuel stability than Sea Foam® Motor Treatment in the triple-length gasoline oxidation stability test (ASTM D525), helping maintain startability and protect against the formation of varnish and gum.

Based on independent third-party testing of AMSOIL Gasoline Stabilizer obtained July 1, 2022 and Sea Foam Motor Treatment purchased June 30, 2022 in a triple-length gasoline oxidation stability test (ASTM D525) using test fuel containing no oxidation-stability-improving additives.

AMSOIL Fights Corrosion

AMSOIL provides corrosion protection Sea Foam* Motor Treatment can’t match, helping maintain power and performance and keeping metal corrosion-free, even when subjected to salt water.

Based on independent third-party testing of AMSOIL Gasoline Stabilizer obtained July 1, 2022 and Sea Foam Motor Treatment purchased June 30, 2022 in a modified NACE TM0172 using synesthetic sea water per ASTM D665B.

APPLICATIONS

Use AMSOIL Gasoline Stabilizer in 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, farm equipment, powered construction equipment, and cars and trucks.

DOSAGE RECOMMENDATION

One ounce of AMSOIL Gasoline Stabilizer treats 2.5 gallons of fuel, including fuel that contains up to 10% 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.

Vintage Car Care

1954 Chevy car. In the fall, as winter approaches, I put the prescribed amount of stabilizer in the gas at each fill. Never know when the last drive of the year will be before the salt is off the roads in the spring.

To early to report?

Added on all my vehicles this fall and hopefully the vehicles that storage half a year will do fine. Thank you!

Stands alone

This is by far the best formulation of a gasoline stabilizer available anywhere. It definitely does what it’s supposed to and outperforms all others that I’ve tried. You truly can have piece of mind when using this. I use it in all of my landscaping equipment.
