This Enzyme Fuel treatment is an easy-to-use fuel treatment that does what it' supposed to do. With this, you don't have to worry about how safe your stored fuel in your storage tanks is. It neutralizes the harmful gasses given off by ethanol and water in old gas, preventing the formation of acids that can damage your throttle body, intake valves and fuel injectors when the engine is re-started. It detoxifies old gas with an enzyme formula. It reduces exhaust emissions and can improve your mpg by 5% to 10%. Additionally, it produces about 100 to 200 extra horsepower.

Ethanol-treated engines are particularly vulnerable to fuel-related problems caused by the exposure to oxygen and contaminants in the storage container. This need has resulted in the invention and distribution of fuel stabilizers which prevent such damage. Gasoline additive STA-BIL Ethanol Fuel Treatment & Stabilizer features a unique formulation which prevents oxidation and storage fuel deterioration in standard and midgrade gasoline and other fuels. With its 360 protection, STA-BIL treats stabilizes up to 160 gallons of fuel.
Under normal and infrequent use, stabilized fuel will keep the full 12-month shelf life. However, if ethanol treated fuel is not stabilized and stored correctly, it may cause engine problems from corrosion within just a few days.
There are two very important times of the year when you should consider adding an ethanol gasoline stabilizer: during the winter when your garage is closed and fuel is being stored and when your boat goes into winter hibernation. Great for use in RVs, automobiles, motorcycles, and gas-powered lawn and garden equipment. For best results, use STA-BIL for ethanol during the storage season.

Frequently Asked Questions (FAQ)
What is the best fuel stabilizer on the market?
Boat owners know that powerful and reliable engine protection is crucial for their safety when out on the water. What they might not realize is that the same protection from ignition problems is just as essential for tailgating, camping and any other type of outside excursion. The best fuel stabilizer can help keep your tank from deteriorating so that hot starts and cold starts are a thing of the past.
Which fuel stabilizer for the motorcycle is the best?
Fuel stabilizers are great for keeping the fuel in your tank from degrading. It helps the fuel stay fresh for longer and protects the inner workings of your engine.
There are three types of fuel stabilizer:
- Ethanol Stabilizer
- Moisture Neutralizer
- Water Remover
Do fuel stabilizers really work?
You certainly won’t have to worry about the additive deteriorating once you put it in your gas tank, but you might not see a huge difference in the quality of gas. If you’re someone who’s super sensitive about gas quality, and you’re using a fuel stabilizer from one of the big-name brands, you might notice a difference in the quality of fuel you get from a gas station versus the fuel you get when you add in the stabilizer ahead of time.
Is seafoam better than Stabil?
Some people enthusiastically proclaim that seafoam has been updated and is far superior. The truth is that modern Seafoam works effectively, is easier to find, and seems to be just as popular as ever.
While Stabil is a great product, Seafoam may be the better choice if it's available for your vehicle.
It's important to point out that there is a second product, originally made by Champion Labs, called Stabil. The original Stabil product is out of business and is no longer manufactured. It is still sold by certain outlets and can be found in some areas.
The product is still sold by certain outlets and can be found in some areas. The product was licensed to STP, which rebranded the product as "Seafoam" in the late '80s. STP eventually changed their label further, but the product is still the same.
Fuel stabilizers are used to prevent loss of octane in gasoline and some diesel fuel. The purpose of gasoline stabilizers is to reduce the evaporation of fuel in storage tanks and in the gasoline-powered fuel delivery system of your engine. Gasoline stabilizers also resist the breakdown of fuel by oxidation of the fuel inside your engine. This results in power surge and loss of fuel efficiency. Gasoline stabilizers contain antioxidants to control these fuel problems and extend the storage life of the fuel.
