Fuel additives are a great way to maintain your car's health and improve its performance. They are designed to address specific issues like cleaning fuel injectors, stabilizing fuel, and improving engine performance. Fuel additives come in various forms, each targeting different aspects of your vehicle’s performance and maintenance. For instance, fuel treatments are designed to minimize carbon and varnish buildup, while fuel injector cleaners are an upgrade that uses one of the strongest cleaning agents, polyetheramine (PEA), to clean more parts of the fuel system. Other types of fuel additives include octane boosters, fuel stabilizers, and ethanol additives. With so many options available, it's important to choose the right additive for your specific needs and follow the manufacturer’s guidelines.

What You'll Learn
Fuel additives for sitting vehicles
Fuel additives are a great way to ensure your vehicle's engine is kept clean and well-maintained, especially if it is sitting idle for long periods. Here are some of the best fuel additives for vehicles that are not frequently used:
STA-BIL Fuel Stabilizer
The STA-BIL fuel stabilizer is a popular choice for those who want to keep their fuel fresh and their fuel systems protected. It can be used for both storage and engine treatment, cleaning carburetors and injectors, and eliminating water. STA-BIL is known to keep fuel fresh for up to 24 months and is suitable for both gasoline and diesel engines.
Star Tron Fuel Treatment
The Star Tron Fuel Treatment is a strong fuel system additive that can stabilize gas, including ethanol blends, for up to two years. It contains antioxidants that prevent fuel separation and enzymes that improve fuel combustibility, resulting in better engine power and fuel economy. It also has a deep cleaning action, removing carbon, gum, and varnish build-up. However, it is only suitable for gasoline engines.
MMO (Marine Motor Oil)
MMO is a type of cylinder lubricant that can be used in fuel-injected vehicles. It helps keep the engine clean and lubricated, which can lead to better fuel economy and reduced wear on critical engine components. MMO is recommended at a dosage of 4oz per 10 gallons of fuel.
Helix Racing Products 5-in-1 Ultimate Fuel Additive
This additive is highly versatile and can be used with both 2-stroke and 4-stroke engines. It eliminates water from fuel systems and stabilizes fuel for up to two years. The product also cleans injectors, carburetors, and other fuel system components, boosting octane by up to two points. Regular use results in increased power, improved mileage, and reduced environmental impact.
Lucas Fuel Treatment Additive
The Lucas fuel treatment additive is designed to clean, lubricate, and neutralize poor-quality fuel. It is made from heat-resistant oils, ensuring its effectiveness under extreme pressure conditions. It contains fuel injector cleaners that remove sediments and sludge, improving spark plug performance. It also includes fuel conditioners that address low sulfur issues in the fuel system. This additive works on both gas and diesel engines and can be used with fuel-injected and carburetor engines.
It is important to note that some vehicles may not require fuel additives, especially if they are not used frequently. Additionally, when selecting a fuel additive, it is essential to consider the type of engine and fuel your vehicle uses, as some additives are designed specifically for gasoline or diesel engines.

Fuel injector cleaners
There are several fuel injector cleaners on the market, with varying effectiveness and prices. Some of the best injector cleaners include Redline Fuel System Cleaner, which has the highest PEA concentration on the market and is easily available on Amazon and in stores. Amsoil Pi is another good option with a high PEA concentration. BG's gas additive is also mentioned as a strong but expensive product.
For those on a budget, cheaper products with Mannich detergents are a decent alternative. While they may not be as robust as PEA-based products, they are still effective in cleaning intake valves and injectors. Chevron Techron, for example, is a top-rated product that uses Mannich detergents.
Other notable injector cleaners include the Helix Racing Products 5-in-1 Ultimate Fuel Additive, which works with both 2-stroke and 4-stroke engines, and the Star Tron Fuel Treatment, which stabilizes gas for up to two years and improves fuel combustibility.
Using fuel injector cleaners periodically can help prevent mechanical issues and keep your engine running smoothly. It can also improve your vehicle's emissions, making the air a little cleaner for those around you.

Octane boosters
BOOSTane is the industry leader in octane engineering, setting the standard for fuel additive technology around the world. BOOSTane offers two types of octane boosters: BOOSTane Premium and BOOSTane Professional. BOOSTane Premium is perfect for performance daily drivers with more aggressive tuning and owners who like to drive fast. BOOSTane Professional is the highest-performing octane booster on the market and is specifically designed for racing vehicles that require high octane fuel.
Lucas Oil Octane Booster is another reliable option for boosting fuel quality, improving power, and reducing emissions. It is versatile and works for turbocharged, high-compression, and naturally aspirated engines. It is also safe for sensors and protects catalytic converters and oxygen sensors from damage.
Rislone’s octane booster is engineered to eliminate engine knocking and restore lost performance. Its concentrated formula improves acceleration and ensures cleaner, more efficient combustion.
Other notable octane boosters include Helix Racing Products 5-in-1 Ultimate Fuel Additive, which boosts octane by up to two points and treats up to 16 gallons of fuel, and K-100 MG All-in-One Gasoline Fuel Treatment & Additive, which eliminates water, stabilizes fuel, and cleans engine and fuel systems.

Fuel stabilizers
One example of a fuel stabilizer is the STA-BIL Storage Fuel Stabilizer, which keeps fuel fresh for up to 24 months, prevents corrosion, and protects the fuel system. It is safe to use in both fuel-injected and carbureted engines and will not damage catalytic converters or oxygen sensors. Another option is the K-100 MG All-in-One Gasoline Fuel Treatment & Additive, which eliminates water, stabilizes fuel, and cleans the engine and fuel systems.
When using a fuel stabilizer, it is important to follow the manufacturer's instructions. Typically, you will need to run the engine for 5-10 minutes to allow the stabilizer to reach the entire fuel system. It is also recommended to use an ethanol-free type of gas and to ensure that the tank is nearly empty before adding the stabilizer.

Ethanol additives
Ethanol in gas can lead to engine corrosion, and when combined with heat, pressure, and exposure to air, it can produce deposits that turn into gum, varnish, and sludge inside your fuel system. This can cause your engine to work harder, resulting in subpar performance. Fuel additives are an effective solution to this problem, as they clean and remove these harmful deposits from the metal components inside your engine, allowing them to be burned in the combustion chamber.
One such additive is Techron Powersports & Small Engine Fuel System Treatment from Chevron, which provides multiple benefits. It not only cleans built-up deposits but also keeps the fuel system clean, protects against corrosion, increases fuel economy, and stabilizes fuel for up to two years. With continuous use, it can help prevent costly repairs, such as rebuilding a carburetor, and improve the overall performance of your vehicle.
Another option is to use Sta-Bil, which is available in red and blue versions. The blue version, Sta-Bil Marine, is specifically designed for ethanol-containing fuel and is more concentrated, treating more gallons per ounce. It helps prevent fuel degradation during storage and protects against corrosion. Additionally, Sta-Bil can be used in conjunction with non-alcohol gas to ensure maximum protection against ethanol-related issues.
For those with older engines, ETHANOLMATE is a leading product designed for use with ethanol-containing petrol (E10 and E5). It acts as a corrosion inhibitor, fuel stability improver, and biocide, providing excellent protection against fuel system corrosion caused by increased acidity during fuel storage. It helps prevent fuel degradation and keeps your engine protected from the harmful effects of ethanol.
By using fuel additives specifically designed for ethanol-containing fuel, you can effectively combat the negative impacts of ethanol on your engine, ensuring better performance, improved fuel economy, and reduced maintenance costs over time.
