WD-40 is a popular multi-purpose product that is often used for lubrication, cleaning, and rust removal. Some people have suggested that spraying WD-40 into a fuel tank can help clean the fuel system and injectors, improve emissions, and increase mileage and power. However, there is much debate on this topic, with some people arguing that it is ineffective or even harmful to the fuel system. While some people have reported successful experiences with using WD-40 in their fuel tanks, especially for derusting, others have cautioned against it, recommending proprietary additives or other methods for cleaning fuel systems.

What You'll Learn
WD-40 is perfumed kerosene, not a lubricant
It is not advisable to spray WD-40 into your fuel tank. While WD-40 is a popular product with many applications, it is not a lubricant and may not be suitable for cleaning fuel systems.
WD-40, or Water Displacement, 40th formula, is a penetrating oil and moisture displacer. It was originally designed to protect the outer skin of the Atlas missile from rust and corrosion. The formula was invented in 1953 for the Rocket Chemical Company, later renamed WD-40 Company, and was first commercialized in 1961. While it is not a grease, it does contain strong lubricating oils and other ingredients that give it multiple applications.
Despite its versatility, WD-40 may not be the best choice for cleaning fuel systems and injectors. Some people suggest that it could be used to clean injectors, but others argue that it will not clean any better than petrol, and will leave carbon and other residues in the fuel system and combustion chamber. It is also not recommended for use on bike chains.
There are alternative products available that are specifically designed for cleaning fuel systems, such as Seafoam, which has been shown to be effective through independent consumer testing. Additionally, some people suggest using acetone to clean injectors and tanks, but this may cause compatibility issues with plastics.
In conclusion, while WD-40 is a useful product with a variety of applications, it is not a lubricant and should not be used in fuel tanks. There are other products available that are more suitable and effective for cleaning fuel systems.

It won't clean the fuel system or injectors
It is not advisable to spray WD-40 into your fuel tank to clean the fuel system or injectors. While WD-40 is a petroleum product, it does not have any particular detergent properties and will not clean the injectors. It will leave carbon and other additive residues in the fuel system and combustion chamber.
There are other products available that are specifically designed to clean fuel systems and injectors, such as Seafoam or Z-max, which have been independently tested and proven to work to some degree. These products are also compatible with common fuel system materials, reducing the risk of damage.
Additionally, there are other methods for cleaning injectors that do not involve the use of any additional products. For example, one method involves dismantling the fuel system and cleaning the injectors by hand with petrol and, for metal parts, carb cleaner. Another method involves using a combination of a battery, straw, and carb cleaner to clean the injectors without the need to dismantle the fuel system.
In conclusion, while WD-40 may be a versatile product with a variety of uses, it is not suitable for cleaning fuel systems or injectors. There are alternative products and methods available that are specifically designed for this purpose and are a safer and more effective option.

It's not a good idea to spray it in your fuel tank
It is not a good idea to spray WD-40 in your fuel tank. Although WD-40 is a petroleum product, it does not have any detergent properties and will not clean your fuel tank. It will leave carbon and other additive residues in the fuel system and combustion chamber.
There are other products available that are specifically designed to clean fuel systems, such as Seafoam, which has been tested by independent consumers and shown to work to some degree. Another option is to use acetone, which will also raise the gasoline octane.
If you are looking to clean injectors, it is possible to do so using xylene. This method involves dismantling the fuel system and cleaning everything through by hand with petrol. Xylene can then be used on metal-only parts to remove varnish and gum, but it strips paint, dries out rubber, and erodes plastics, so it should be used with caution.
WD-40 is not an effective fuel alternative. Although it is a flammable substance, an engine will die quickly if it is filled with a tank of WD-40.

It's better to use proprietary additives tested for fuel systems
While some people suggest using WD-40 in a fuel tank to clean the fuel system and injectors, this is not recommended. There are no known detergent properties of WD-40, and it will leave carbon and other additive residues in the fuel system and combustion chamber.
It is better to use proprietary additives that have been tested for fuel systems. These products have been compatibility-tested with all common fuel system materials. For example, Seafoam is a popular additive used for maintenance. Fuel Ox® Star Plus™ is another additive designed to improve fuel system efficiency and reduce fuel-related problems and service calls.
Additives like acetone can also be used to clean injectors and tanks, but there are concerns about the compatibility of plastics in the tank. It is important to use additives that have been specifically designed for fuel systems to avoid any potential damage to the vehicle.
Using a product that has been professionally formulated for fuel treatment ensures that the additive will be compatible with the engine and fuel type. These additives can improve fuel economy and enhance vehicle performance. They can also address specific problems in the fuel system or engine, such as stabilization, icing, sludge buildup, and corrosion.
In summary, while some people may suggest using WD-40, it is better to use proprietary additives that have been tested for fuel systems. These additives are designed to improve performance, enhance fuel economy, and address specific issues. By using these products, you can ensure the compatibility and safety of your vehicle while maintaining or improving its performance.

It can be used to prevent rusting
WD-40 is a popular product that has been used for various purposes, including cleaning fuel systems and injectors. However, its effectiveness in this regard is questionable, as some people believe that it does not possess detergent properties and may not be suitable for certain fuel system components.
One of the well-known uses of WD-40 is rust prevention. Rust occurs when iron, oxygen, and water combine, leading to the corrosion of metal surfaces. To prevent rust, it is essential to understand its causes and address them proactively. WD-40 offers a range of products specifically designed for rust prevention, such as the WD-40 EZ-REACH™ and the WD-40 Specialist® Rust Remover Soak. These products can help remove and prevent rust, ensuring the integrity of metal surfaces.
The WD-40 Specialist Corrosion Inhibitor is an anti-rust spray that provides long-lasting protection. It is ideal for use in challenging environments, such as high humidity, and can be applied to stored parts or tools to prevent rust formation over time. This non-drying formula stays where it is sprayed, making it a convenient option for rust prevention.
In addition to the specialist product line, the original WD-40 Multi-Use Product is also effective in preventing rust. Its formula, originally developed to protect rocket engines from corrosion, can be used to prevent rust on tools, in fuel tanks, and on RC cars. Users recommend spraying it on metal surfaces, screws, and joints to prevent rust, especially after exposure to water. However, some people suggest following up with a light oil to improve its rust-prevention capabilities.
While WD-40 can be useful for rust prevention, it may not be the best option for long-term protection. Some users have reported that it is messy, too runny to cling to surfaces effectively, and may not provide adequate rust prevention on its own. It is often suggested to use other products in conjunction with WD-40 or as an alternative for better results. These include motor oil, wax coatings, Fluid Film, Boeshield, and CorrosionX.
