Fuel stabilizers are used to protect engines from the effects of stale gas, which can cause engine deterioration. They reduce the evaporation rate of the fuel's volatile compounds and prevent moisture absorption by creating a protective layer over the gasoline. The recommended dosage of fuel stabilizer is one ounce of stabilizer per two gallons of fuel. This will keep the fuel fresh for at least 12 months. However, some people choose to double the dosage for winter or if the fuel is being stored for an extended period of time.

STA-BIL® Fuel Stabilizer: 1 oz per 2.5 gallons of fuel
STA-BIL® Fuel Stabilizer is a trusted additive that has been treating the gas of vehicles, generators, boats, motorcycles, and small engine equipment for over 60 years. It is compatible with any type of gasoline-powered equipment that you plan to store for a month or more. The product is safe to use in both fuel-injected and carbureted engines and will not damage catalytic converters or oxygen sensors. It prevents the formation of gums and varnish that can clog fuel injectors and contains a fuel injector cleaner to improve engine performance.
STA-BIL® Fuel Stabilizer is easy to use. Simply pour one ounce (30ml) of the additive for every 2.5 gallons (9.5 litres) of fuel directly into the fuel reserve of the vehicle, generator, lawnmower, gas can, or any other engine you are storing. After adding the product, run the engine for at least five minutes to allow the product to run through the entire fuel system and keep every component of the engine protected.
It is important to note that STA-BIL® Fuel Stabilizer should only be used with fresh fuel. To avoid condensation build-up in the tank during storage, keep the gas can or tank 95% full. The product has a shelf life of two years after the bottle has been opened, provided it is tightly capped and stored in a cool, dry place.
STA-BIL® Fuel Stabilizer will keep fuel fresh for up to 24 months, eliminating the need to drain your tank before storing your engine. This product ensures quick, easy starts and protects your engine during long-term storage.

Toro Premium Fuel Treatment: 1 oz per 2 gallons of fuel
Fuel stabilizers are essential for preserving gasoline and diesel fuel, which naturally break down over time. Toro Premium Fuel Treatment is one such stabilizer that helps ensure clean, reliable engine performance and protection. It is suitable for lawnmowers, snow blowers, weed whackers, leaf blowers, and other small engine power equipment.
Toro Premium Fuel Treatment is easy to use. Simply add one fluid ounce of the treatment per two gallons of fuel. This will keep the fuel protected and fresh for at least 12 months, or even up to two years, according to some sources. It is recommended to use the treatment with every fill-up to provide protection and keep your machine's system clean.
Using a fuel stabilizer is especially important if you are storing your equipment for an extended period. Ideally, you should only purchase the amount of fuel that you will use within 30 days, as untreated gasoline can start to break down in as little as 30 days. Over time, fuel can absorb moisture from the atmosphere, leading to corrosion and clogging of system components.
Toro Premium Fuel Treatment also contains detergents that dissolve fuel system deposits. This helps to ensure easy starting, even after seasonal storage. By preventing the formation of gummy deposits, the treatment protects your equipment and extends its life.

Gasoline shelf life: Fuel deteriorates in a few months
Gasoline has a shelf life of three to six months. Within a few months, untreated gasoline loses its potency and can cause damage to the internals of the fuel system. Within six months, stored fuel can completely varnish the carburetor, requiring cleaning before the engine can be used again.
To prevent this, fuel stabilizers can be used. Fuel stabilizers are chemical additives designed to preserve the quality of gasoline when stored for extended periods. They can extend the shelf life of gasoline to up to two years. Fuel stabilizers prevent gasoline from breaking down and can be left in gas tanks, vehicles, or small engines. They also help prevent engine failures and prevent the engine from failing to start after long periods of storage.
The optimal time to add a fuel stabilizer is when fueling up, especially if the vehicle or equipment will be stored for 30 days or more. The recommended ratio is one ounce of stabilizer per 2.5 gallons of fuel.
It is important to note that fuel stabilizers are not miracle additives. They only help slow the aging process and provide a couple of extra months of shelf life. Additionally, the effectiveness of fuel stabilizers diminishes over time due to oxidation. An unopened bottle of fuel stabilizer has a shelf life of approximately two years, while an opened bottle has a shelf life of two years after it has been opened.

Fuel stabilizers for 2- and 4-cycle engines
Fuel stabilizers are an essential product for anyone with vehicles or equipment that are stored for long periods or not used daily. They prevent fuel degradation, which can cause gum and varnish deposits, and they also clean, lubricate, and maintain fuel pumps, carburetors, fuel injectors, and compression rings.
2-Cycle Engines
Some 2-cycle engine oils already contain fuel stabilizers, but these may not be sufficient to keep gas fresh for long periods. It is recommended to add extra fuel stabilizer to your gas cans before filling them to ensure the gas stays fresh. This is especially important if your equipment is stored during the winter months.
There are various fuel stabilizers on the market that are suitable for 2-cycle engines. Sta-Bil, for example, is safe for use in all gasoline engines, including 2-cycle. One 4 oz bottle treats up to 10 gallons of fuel and can be used in vehicles, motorcycles, lawnmowers, snow blowers, boats, and generators. To treat fuel, simply add 1 oz of Sta-Bil for every 2.5 gallons of fuel.
Another option is Echo Power Blend 2-Stroke Engine Oil, which also contains a fuel stabilizer. This product is available at BB stores and has received positive reviews for its effectiveness.
4-Cycle Engines
Fuel stabilizers are also available for 4-cycle engines. Lucas Fuel Stabilizer, for example, is safe to use in all grades of gasoline and in all 2- and 4-cycle engines. It prevents fuel degradation and the formation of gum and varnish deposits. To use, simply add 1 fluid ounce of Lucas Fuel Stabilizer for every 2.5 gallons of gasoline.
In addition to these dedicated fuel stabilizers, some engine oils can also be used as fuel stabilizers for 4-cycle engines. For example, a powertrain engineer for Cadillac recommends using 2-stroke oil as a fuel stabilizer, adding roughly one ounce per gallon of gasoline. However, it is important to note that this may not be effective for fuel stored for longer than a few months.
