When you own small engines like lawnmowers, generators, snowblowers, or leaf blowers, it is important to take good care of them to ensure that they run properly and last a long time. One of the most important steps in maintaining small engines is ensuring that their fuel supply is clean and stable. Fuel stabilizers are a crucial tool in keeping the fuel in your small engines fresh and free from contaminants. In this article, we will go over what fuel stabilizers are, how they work, and why they are so important for the longevity of your small engines.

What Are Fuel Stabilizers?

Fuel stabilizers are chemical additives that are designed to preserve the quality of gasoline or diesel fuel by preventing the fuel from breaking down or becoming contaminated over time. They work by keeping the fuel free from moisture, which can cause rust and corrosion, and by preventing the fuel from oxidizing, which can cause varnish and gum deposits to form in the fuel system.

Fuel stabilizers are especially important for small engines because they tend to sit for long periods of time without being used. This can cause the fuel to break down and become contaminated with water or other impurities, which can lead to poor engine performance or even engine failure.

How Do Fuel Stabilizers Work?

Fuel stabilizers work by inhibiting the chemical reactions that occur when gasoline or diesel fuel is exposed to air, heat, and moisture. When fuel is stored for long periods of time, it can start to break down due to these reactions, which can cause the fuel to become less effective and even harmful to your engine.

Fuel stabilizers contain chemicals that bond with the fuel molecules to prevent them from reacting with the air, heat, and moisture in the environment. They also contain antioxidants that prevent the fuel from oxidizing, which can cause varnish and gum deposits to form in the fuel system.

When you add a fuel stabilizer to your small engine’s fuel tank, it will mix with the fuel and work to keep it fresh and clean for up to a year or longer, depending on the brand and type of stabilizer you use.

Why Are Fuel Stabilizers Important for Small Engines?

Small engines are particularly vulnerable to fuel degradation and contamination because they often sit unused for long periods of time. When small engines are not used, the fuel in the tank can break down and become contaminated with water and other impurities, which can lead to engine problems when the engine is finally started again.

Fuel stabilizers can help prevent these problems by keeping the fuel in the tank fresh and free from contaminants. By using a fuel stabilizer, you can extend the life of your small engine and ensure that it is always ready to start when you need it.

In addition, fuel stabilizers can also help prevent the formation of varnish and gum deposits in the fuel system, which can clog fuel lines and filters and lead to poor engine performance or even engine failure.

Types of Fuel Stabilizers

There are several types of fuel stabilizers available on the market, each with its own unique blend of chemicals and additives. The most common types of fuel stabilizers include:

  1. Alcohol-based stabilizers: These stabilizers work by absorbing moisture and preventing it from coming into contact with the fuel. They also contain detergents that help keep the fuel system clean. Check out :
    • Sta-Bil 360 Protection Ethanol Treatment and Fuel Stabilizer
    • Sea Foam SF-16 Motor Treatment
    • HEET Gas-Line Antifreeze & Water Remover
  2. Petroleum-based stabilizers: These stabilizers work by coating the fuel molecules and preventing them from reacting with the air and moisture in the environment. They also contain antioxidants that prevent the fuel from oxidizing. Check out:
    • STA-BIL Storage Fuel Stabilizer
    • Briggs & Stratton 100119 Fuel Treatment
    • Star Tron Enzyme Fuel Treatment
  3. Synthetic stabilizers: Synthetic stabilizers are designed to work in extreme temperatures and conditions. They are typically used in aviation and marine industries, where the engines can sit unused for long periods. Synthetic stabilizers can prevent corrosion and deposit buildup and are often recommended for fuel that will be stored for a year or longer. Check out :
    • PRI Fuel Stabilizer
    • Lucas Oil 10303 Fuel Stabilizer
    • Royal Purple Max-Tane Total Diesel Performance Fuel Treatment
  4. Enzyme-based stabilizers: These fuel stabilizers use enzymes to break down the varnish and gum that forms in fuel. Enzymes are biological catalysts that increase the rate of a chemical reaction, in this case, breaking down the harmful byproducts of stale gasoline. Enzyme-based stabilizers can also help reduce harmful emissions and improve fuel economy by ensuring that the fuel burns more completely. Check out:
    • Star Tron Enzyme Fuel Treatment
    • Biobor JF Diesel Fuel Biocide and Lubricity Additive
    • Power Service 03016-09 +Cetane Boost Diesel Kleen Fuel Additive
  5. Combination stabilizers: Combination stabilizers, as the name suggests, combine the benefits of both alcohol-based and petroleum-based stabilizers. They are designed to work in all gasoline blends, including E10, E15, E85, and even ethanol-free fuel. These stabilizers are also suitable for use in two-stroke and four-stroke engines, and they protect against the harmful effects of water, oxidation, and corrosion. Check out:
    • STA-BIL 22208 Storage Fuel Stabilizer
    • Sea Foam Motor Treatment

How to Use Fuel Stabilizers for Small Engines

Using fuel stabilizers for small engines is a straightforward process. Here are the general steps to follow:

  1. Choose the right fuel stabilizer for your needs based on the factors discussed earlier in this article.
  2. Add the fuel stabilizer to the fuel tank according to the manufacturer’s instructions. In general, you should add the stabilizer to fresh gasoline before storing the equipment for a long period. Make sure to mix the stabilizer and gasoline well.
  3. Start the engine and run it for several minutes to ensure the treated fuel circulates through the carburetor and fuel lines.
  4. Store the equipment in a cool, dry place away from direct sunlight and other heat sources.
  5. If you plan to store the equipment for more than a few months, you should also drain the fuel tank and carburetor before storing it. Make sure to run the engine until it stops to remove as much fuel as possible. This will help prevent gum and varnish buildup in the fuel system.

Conclusion

Using fuel stabilizers for small engines is a simple and effective way to protect your equipment and ensure it starts up smoothly when you need it. By choosing the right stabilizer for your needs and using it correctly, you can extend the life of your equipment and avoid costly repairs. Keep in mind that using fresh gasoline and following the other precautions mentioned earlier in this article will also help ensure your equipment runs smoothly. If you have any questions about fuel stabilizers or need help selecting the right product for your needs, consult your equipment manufacturer or a reputable mechanic.
