What to Put in Your Gas Tank to Clean and Enhance Performance

Maintaining a clean and efficient gas tank is essential for the optimal performance of your vehicle. Over time, contaminants such as dirt, rust, and debris can accumulate in the fuel system, leading to reduced fuel efficiency and engine problems. To address these issues, it’s crucial to use the right products to clean your gas tank. In this article, we’ll explore the various options available and guide you on what to put in your gas tank to ensure a thorough and effective cleaning process.

Fuel Additives: The Magic Elixir for Your Gas Tank

Fuel additives are a popular and convenient solution for cleaning your gas tank. These specially formulated chemicals are designed to break down deposits, remove contaminants, and improve fuel system performance. When searching for a fuel additive, look for products that contain detergents and cleaning agents. These additives work by preventing the formation of carbon deposits and removing existing buildup, ensuring a cleaner and more efficient fuel system.

One highly recommended fuel additive is Chevron Techron Concentrate Plus. This product is known for its powerful cleaning capabilities, effectively removing deposits from fuel injectors, carburetors, and combustion chambers. Regular use of such additives can help maintain a clean gas tank and prevent performance issues.

Fuel System Cleaners: Targeted Cleaning for Maximum Efficiency

For a more targeted approach to cleaning your gas tank, consider using fuel system cleaners. These cleaners are specifically formulated to remove deposits from critical components such as fuel injectors, intake valves, and the combustion chamber. They come in liquid form and are typically added to the fuel tank during a fill-up.

One notable product in this category is Red Line Complete SI-1 Fuel System Cleaner. This cleaner not only helps eliminate deposits but also provides lubrication to critical engine components, reducing friction and improving overall performance. When choosing a fuel system cleaner, ensure compatibility with your vehicle’s make and model for optimal results.

Ethanol Fuel System Cleaner: Tackling Ethanol-Related Issues

With the increasing prevalence of ethanol-blended fuels, addressing ethanol-related issues is crucial for maintaining a clean gas tank. Ethanol can lead to the accumulation of water in the fuel system, causing corrosion and other problems. Ethanol fuel system cleaners are specifically designed to address these issues by absorbing and removing water from the fuel system.

Star Tron Enzyme Fuel Treatment is a notable product in this category. It not only stabilizes fuel for up to two years but also helps prevent phase separation, a common issue with ethanol-blended fuels. By using an ethanol fuel system cleaner, you can protect your gas tank from the harmful effects of water contamination and ensure optimal engine performance.

Rust Inhibitors: Safeguarding Your Gas Tank from Corrosion

Rust is a common problem in older vehicles or those exposed to harsh environmental conditions. Rust particles can contaminate the fuel system, leading to clogs and reduced fuel flow. Rust inhibitors are designed to prevent and eliminate rust, protecting your gas tank and fuel system from corrosion.

One effective rust inhibitor is the POR-15 Fuel Tank Sealer. This product not only stops existing rust but also prevents new rust from forming. Applying a rust inhibitor to your gas tank can extend its lifespan and contribute to the overall health of your vehicle’s fuel system.

DIY Solutions: Home Remedies for Gas Tank Cleaning

If you prefer a more hands-on approach, there are DIY solutions that you can use to clean your gas tank. One common method involves using a mixture of white vinegar and baking soda. The acidic nature of vinegar helps break down deposits, while baking soda acts as a mild abrasive to scrub away contaminants.

To use this DIY solution, mix equal parts white vinegar and baking soda to create a paste. Apply the paste to the inside of the gas tank and let it sit for a few hours. Afterward, rinse the tank thoroughly with water to remove the residue. While this method may be suitable for mild cleaning, it may not be as effective as commercial products for more stubborn deposits.


Maintaining a clean gas tank is essential for the longevity and efficiency of your vehicle. Whether you choose fuel additives, fuel system cleaners, ethanol fuel system cleaners, rust inhibitors, or DIY solutions, it’s crucial to follow the manufacturer’s instructions and use products compatible with your vehicle. Regular maintenance and cleaning will not only enhance fuel efficiency but also prevent costly repairs down the road. By understanding what to put in your gas tank to clean it, you can keep your vehicle running smoothly and enjoy the benefits of improved performance and fuel economy.
