WD-40 in the fuel tank to fix gas leaks
While some people believe that WD-40 can be used to fix gas leaks in a fuel tank, this is not recommended. Although WD-40 is a flammable substance, using it in a fuel tank will cause the engine to die. One user on Reddit reported that their vehicle ran for two days after using WD-40 to fix a gas leak, but then wouldn't start at all.
WD-40 is a petroleum product, similar to petrol, and so will solvate and remove the same things. It will also leave carbon and other additive residues in the fuel system and combustion chamber. It is therefore recommended to use a product such as Seafoam, which has been tested by independent consumers and shown to work to some degree.
It is also worth noting that the official WD-40 website lists lubricating gas cap locks and levers as one of the uses for the product. However, this refers to the locks and levers on the outside of the gas cap, not the fuel tank itself.
Overall, while it may be tempting to try using WD-40 as a quick fix for a gas leak in your fuel tank, it is not an effective solution and may cause more problems than it solves.

Using WD-40 to prevent flash rusting
While some people believe that putting WD-40 in your fuel tank can help improve fuel efficiency, this is not true. However, WD-40 can be used to prevent flash rusting.
Flash rusting is a common problem with fuel tanks, and it can be challenging to prevent. One user on a motorcycle enthusiast forum claimed that preventing flash rusting is impossible, even after using a variety of rust removal methods and trying to remove residual water with WD-40. However, another user on the same forum disagreed, stating that they had success using WD-40 to prevent rust on a bare engine block. They left it for three years, and upon retrieving it, there was no rust.
WD-40 Rust Remover Soak is a product specifically designed to remove rust. It is a 100% non-toxic and biodegradable formula that eats away rust, leaving behind clean bare metal that can be treated to prevent future rust. To use the soak, you need to fill a container with enough solution to fully submerge the rusty part. It is important to note that the solution should not be diluted. The length of time the item needs to soak depends on the amount of rust, with light rust taking as little as 30 minutes and heavy rust taking up to 24 hours. After soaking, the item should be rinsed and dried completely. If there is still rust remaining, the process can be repeated. It is important to keep used and unused solutions separate and to dispose of the solution properly once it turns dark black and loses its effectiveness.
To prevent flash rusting after removing rust, it is recommended to use WD-40 Original Formula for flash rust protection or WD-40 Specialist Long-Term Corrosion Inhibitor for long-term protection. For painted parts, a simple repair with matching paint can be done.

False advertisements for using WD-40 in fuel tanks
Several people have encountered advertisements claiming that using WD-40 in fuel tanks can save fuel. These ads feature images of a can of WD-40 spray being pointed at a car's gas tank, with catchy titles such as "The One And Only WD40 Trick Everyone Should Know." However, these advertisements are misleading and false.
When users click on these ads, they are directed to a lengthy slideshow article filled with more advertisements. Despite the enticing promise of a secret trick, none of the 70 pages in the article mention anything about spraying WD-40 into a vehicle's gas, diesel, or petrol tank. This practice of leading users through multiple pages of advertisements is known as advertising "arbitrage," where the goal is to generate more revenue from the ads on the slideshow pages than the cost of the initial ad.
While WD-40 is a versatile product with multiple uses, it is essential to follow the instructions and warnings on the packaging. The official product description of WD-40 states that it can protect metal from rust and corrosion, and the company offers a range of lubricants, penetrating oils, cleaners, and rust removal products. However, it is not meant to be used in fuel tanks, and doing so can potentially cause damage to your vehicle.
Some individuals who have tried using WD-40 in their fuel tanks have reported experiencing issues with their vehicles. One person shared that their car refused to start after initially running well for a couple of days. It is important to exercise caution and only use the gasoline or diesel specified by the manufacturer in your vehicle's fuel tank to avoid any potential problems.
In conclusion, the advertisements claiming that WD-40 can be used in fuel tanks to save fuel are false and misleading. While WD-40 has its uses, it is not intended for this purpose, and consumers should be wary of such deceptive marketing tactics. Always follow the recommended guidelines and seek reliable sources for information to make informed decisions regarding your vehicle's maintenance.

Cleaning fuel injectors with WD-40
It is not advisable to put WD-40 in your fuel tank, despite some advertisements claiming that it can help you save fuel. While it may not damage your car, it can cause problems with starting your vehicle.
If you are looking to clean your fuel injectors, there are a few methods you can try. One method involves using a battery and a can of carb cleaner. First, cut off the injector plug and a couple of inches of wire. Then, solder the wires to a 2-AA battery holder and cover the solder joints with liquid electrical tape. Next, take the screen out of a bad or spare injector and insert a thin red straw from the carb cleaner can into the screen. Fill the top of the screen with JB Weld and let it dry for a couple of days. Once dry, use a sharp knife to cut off the bottom of the screen, exposing the straw. Remove the screen from the injector you want to clean and insert the straw into it. Finally, plug the battery holder into the injector to open it up.
Another method for cleaning fuel injectors is to use a product specifically designed for this purpose, such as a fuel injector cleaner additive. These additives are poured into the fuel tank and are designed to remove deposits and build-up from the injectors.
It is important to note that while some people have reported using WD-40 to clean their fuel injectors, it is not recommended. There are specialized products available that are designed for cleaning fuel injectors and are a better option to ensure the job is done effectively and safely.
Additionally, it is always a good idea to consult a professional mechanic or a trusted car care specialist before attempting any maintenance or cleaning on your vehicle, especially if you are unsure about the process or the products being used. They can provide guidance and advice tailored to your specific vehicle and help you avoid any potential issues or damage.

Alternative additives to WD-40 for fuel tanks
While some people suggest that WD-40 can be used in fuel tanks to clean the fuel system and injectors, others argue that it is not a good idea. One user on a Suzuki GSXR forum states that they have "not heard that WD40 has any particular detergent properties" and that it might "leave carbon and other additive residues in the fuel system and combustion chamber". Another user on the same forum mentions that they would not put WD-40 in their tank and instead recommends using Seafoam as an additive. This user also suggests adding acetone to gasoline to clean injectors and raise gasoline octane, but cautions about the compatibility of acetone with plastics.
Another forum user advises against using any fluids other than petrol and carb cleaner (xylene) to clean injectors and metal parts, as other fluids can cause more trouble than they are worth. This user also mentions that Z-max is the only additive they put in their fuel tank to treat the pump and injectors.
It is important to exercise caution when considering adding any substance to a fuel tank other than the gasoline or diesel specified by the manufacturer. While some people have reported using WD-40 in their fuel tanks without issues, it is always best to follow the manufacturer's recommendations to avoid potential problems or damage to your vehicle.
