The use of alcohol in fuel tanks is a controversial topic, with some people advocating for its benefits, while others highlight its potential drawbacks. Some individuals use alcohol, specifically rubbing alcohol or isopropyl alcohol, as a fuel additive, believing it helps clean the engine, improve mileage, and enhance acceleration. On the other hand, critics argue that the water content in rubbing alcohol can cause issues in the fuel system and that there are more effective alternatives available. Additionally, there have been reports of people intentionally adding alcohol to fuel tanks as a prank, which can lead to costly repairs.
Characteristics and their values regarding putting alcohol in a fuel tank

What You'll Learn
Rubbing alcohol in fuel tanks can be used to treat the fuel system
Rubbing alcohol, or isopropyl alcohol, has been used by some as a fuel additive for years. It is often used to absorb water in the fuel tank, with the belief that it burns up any moisture in the tank. However, others argue that the water content in rubbing alcohol (around 70%) will separate and settle at the bottom of the tank, potentially damaging the fuel system.
Some people add small amounts of rubbing alcohol to their fuel tanks as a treatment, claiming it helps keep things clean and improves acceleration and mileage. One person who added rubbing alcohol to their gas tank reported that their engine looked steam-cleaned at the end of the tank. Another person claimed that using rubbing alcohol in their gas tank has prevented their vehicles from failing to start in extremely cold temperatures.
It is important to note that car manufacturers typically do not recommend ethanol concentrations higher than 5%, and that most gasoline already contains about 10% alcohol. Additionally, alcohol can react poorly with rubber and plastic components in the fuel system, potentially causing damage.
If you are considering using rubbing alcohol as a fuel additive, it is essential to exercise caution and thoroughly research the potential risks and benefits for your specific vehicle and situation.

It can burn up moisture in the tank
Rubbing alcohol is often considered a home remedy to eliminate water from gas tanks. The idea is that when alcohol is added to a gas tank with water and gasoline, the alcohol sinks to the bottom and absorbs the water, creating a mix that is no longer harmful to the engine. The water, gas, and alcohol are then burnt up and removed from the tank.
However, it's important to note that rubbing alcohol is typically composed of 70% alcohol and 30% water. This means that by adding rubbing alcohol, you are introducing more water into the fuel system, which can be damaging to the vehicle. As such, it may be preferable to use a product specifically designed to remove water from gas tanks, such as HEET or Watersorb. These products contain forms of alcohol that are better suited for absorbing water.
In some cases, individuals have added alcohol to their gas tanks to clean away carbon deposits and improve engine performance. The alcohol is believed to remove deposits through its vapors, and some have reported increased acceleration and better fuel efficiency. However, it is important to exercise caution and consult a professional before using any substance in your fuel tank, as incorrect usage may cause damage to your vehicle.
Additionally, it is worth noting that modern gasoline often already contains a percentage of ethanol, which can act as a cleaner for the fuel system. As such, the use of additional alcohol may not provide any significant benefits and could potentially cause issues if not used correctly.

It can be used to pass emissions testing
Adding alcohol to your fuel tank can help you pass emissions testing. However, it is important to note that this method is not without its risks and may not be suitable for all vehicles.
One of the primary concerns when adding alcohol to your fuel tank is the potential damage it can cause to the fuel system. Alcohol can be corrosive and incompatible with the rubber, metal, and plastic components in the fuel system, leading to leaks and other issues. It is crucial to exercise caution and carefully consider the risks before proceeding.
To mitigate the risks, it is recommended to use a small amount of alcohol and dilute it with gasoline. A common suggestion is to use a ratio of one gallon of denatured alcohol to three or four gallons of premium gasoline. This mixture should be added to a partially empty tank, and the car should be allowed to warm up for about half an hour before the emissions test.
After passing the test, it is essential to dilute the alcohol mixture by filling the tank with fresh, premium gasoline. This step is crucial to prevent potential damage to the fuel system.
Additionally, it is worth noting that while adding alcohol can help pass emissions testing, it is not a long-term solution. For a more permanent fix, consider replacing the catalytic converter or consulting a professional to explore other options.
While adding alcohol to your fuel tank can be a temporary solution to pass emissions testing, it should be approached with caution and careful planning to minimise potential risks to your vehicle's fuel system.

It can be used to clean the engine
Rubbing alcohol is a common product used to treat fuel tanks. It is often used to absorb water in the fuel tank, but some people argue that it ends up adding more water. Rubbing alcohol is made up of 70% alcohol and 30% water, and the water can settle at the bottom of the tank and start to ruin the fuel system.
However, some people have used it to clean their engines. One person shared that they filled an old lawnmower's tank with 50% gas and 50% rubbing alcohol (70%) and it ran fine. At the end of the tank, the engine looked like it had been steam cleaned. Another person shared that they used rubbing alcohol in their moped and had to clean the carb a lot.
Isopropyl alcohol, which is a type of rubbing alcohol, can also be used to clean the engine. It has a high octane rating of approximately 120, so it shouldn't lead to detonation. It is also a weaker solvent than ethanol or methanol, so it has minimal corrosion concerns.
Overall, while there are mixed opinions on whether to use rubbing alcohol in fuel tanks, some people have found it effective for cleaning their engines.

It may cause harm to the vehicle
While some people have added alcohol to their fuel tanks without any apparent issues, it is generally not recommended as it may cause harm to the vehicle.
Firstly, alcohol can attract moisture from the air, which can lead to water accumulation in the gas tank. Water in the gas tank can cause significant damage to the vehicle's engine and fuel system. While some believe that adding alcohol can eliminate water from the tank, this is not always effective. Rubbing alcohol, for example, contains about 70% alcohol and 30% water, so adding it to the fuel tank may introduce more water than it removes.
Secondly, alcohol can cause issues with certain types of engines, such as outboards and carbed Merc's, as mentioned in some forum discussions. It is important to note that modern gasoline already contains about 10% ethanol, and adding additional alcohol can alter the fuel composition and potentially cause complications.
Additionally, alcohol can impact the performance and acceleration of the vehicle. While some individuals have reported improved acceleration and mileage, others have experienced the opposite effect. It is important to note that using paint thinner, which can increase the octane level, may also have adverse effects on the vehicle's performance.
Furthermore, alcohol can damage sensors and valve components in the fuel system. In one instance, a user reported that alcohol was poured into their gas tank, resulting in a sensor valve malfunction that prevented the tank from filling with gas. The issue required professional repair, incurring additional costs and causing inconvenience.
Lastly, while some mechanics recommend using alcohol to clean carbon deposits from the engine, there are specifically designed products available for this purpose, such as bg44k and other fuel injector cleaners. Using alcohol as a cleaner may provide temporary benefits, but it is not a substitute for proper engine maintenance and the use of approved cleaning solutions.
