Denatured alcohol is ethanol, and it is often used as a fuel additive to clean the engine. It is a common home remedy to pour denatured alcohol into a gas tank to eliminate water. The alcohol sinks to the bottom and absorbs the water, creating a combination that is no longer harmful to the engine. However, it is important to note that denatured alcohol can be corrosive, and its use may depend on the age and condition of the fuel.

Denatured alcohol is safe to use in fuel tanks
Denatured alcohol is a common additive used in fuel tanks to prevent water build-up and clean injectors. It is a generic ingredient in most fuel system cleaners. Denatured alcohol is ethanol, which is already present in E10 fuel.
While some people are hesitant to use ethanol-based fuels due to their effects on rubber hoses and gaskets, denatured alcohol can be useful in certain situations. For example, it can help remove water from fuel tanks and clean injectors. In small amounts, it can be safe to use as a fuel additive. One source recommends a standard container per tank of gasoline, used every other month. Another suggests a quart of denatured alcohol for each tank.
However, it is important to exercise caution when using denatured alcohol. One source states that over 10% denatured alcohol is corrosive, so it is best to limit it to around 10% and burn it out quickly. Additionally, denatured alcohol can loosen tank-wall and hose deposits, potentially clogging filters and other fuel delivery components. Therefore, it is important to change the fuel filters and carry spares.
While denatured alcohol can be safe to use in fuel tanks in small amounts, it is always a good idea to consult a professional or an expert before using any fuel additives.

It can be used to clean the engine
Denatured alcohol, also referred to as "methylated spirits", is a form of ethanol with specific additives to deter consumption. It is a poisonous liquid with a nauseating smell and a poor taste. Denatured alcohol is a useful product with a wide variety of applications, from general at-home cleaning to industrial work.
One of the most common uses of denatured alcohol is as a cleaning agent. It can be used to clean the inside of engines, as it is capable of removing dirt, grease, glue, wax, and other types of grime. It is also one of the most widely used methods to clean the inside of engines, bearings, and starter shafts. It is recommended to use 100% denatured alcohol, as it does not contain water, unlike rubbing alcohol, which is made for personal use.
When using denatured alcohol to clean engines, it is important to take certain precautions. Firstly, denatured alcohol is extremely flammable, so it should be stored properly and kept away from sparks or flames. It is also important to wear protective clothing, goggles, and gloves to prevent skin and eye contact during use.
To clean the inside of an engine with denatured alcohol, it is recommended to use Q-tips or a lint-free cloth. It is important to ensure that no lint or fabric pieces are left inside the engine. Additionally, to prevent "drying out" of the parts cleaned with denatured alcohol, it is recommended to re-lube moving parts with a light coat of oil or fuel.
Denatured alcohol is also commonly used to clean injectors and injector cylinders. It is effective in removing resin and has a higher flashpoint, leading to faster drying times. It also does not cause the injector end seal to warp or swell, making it a safer option than other chemicals like acetone.

It can be used to pass emissions tests
Denatured alcohol can be used to pass emissions tests. Denatured alcohol, also known as methylated spirits, is ethanol with additives that make it poisonous, foul-smelling, and nauseating to discourage recreational consumption.
Some people have suggested adding denatured alcohol to the fuel tank to pass emissions tests. One source suggests that the primary thing that inspectors are checking for is gasoline fumes. Denatured alcohol won't release any gasoline fumes as it burns, so adding a gallon of denatured alcohol to the tank with a couple of gallons of gasoline may help pass the test. However, it is important to note that denatured alcohol is corrosive and can damage metal and rubber parts it comes into contact with. It is also relatively expensive compared to other options.
Another suggestion is to use a product called "Guaranteed to Pass" from parts stores instead of denatured alcohol. This product is intended to help pass emissions tests and may be safer for the vehicle. It is also recommended to try a fuel system cleaner or a new catalytic converter before resorting to chemical additives.
If using denatured alcohol, it is recommended to mix it with gasoline at a ratio of 1:3 or 1:4. The vehicle should be driven normally to allow the mixture to blend, and the tank should be drained and refilled with normal gasoline after the test to prevent damage to the engine.
It is worth noting that some people have tried using denatured alcohol and failed the emissions test. There are mixed results, and it may depend on the specific vehicle and test conditions.

It can be used to remove water from the tank
Denatured alcohol is a common additive to fuel tanks, especially in boats, and can be used to remove water. It is a powerful cleaner that can be purchased at Walmart or Lowes.
To use denatured alcohol to remove water from your fuel tank, you must first drain the tank. Then, add the denatured alcohol—about a quart per tank is recommended by some, while others suggest a full bottle (16 oz) to a half tank of gas. Let the engine idle for a bit, and then take the vehicle for a run to burn off the remaining alcohol. It is important to note that denatured alcohol is ethanol, which can be aggressive in attacking rubber in the fuel system, so it should not be used regularly.
Some people opt to use water-absorbing additives, which can be poured directly into the fuel tank. These additives mix with the fuel and absorb water before reaching the bottom of the tank. However, it is important to note that these additives will not make "bad fuel" good again. Additionally, draining the tanks and adding gallons of fresh fuel is another method to remove water from the tank.
Another option is to use acetone, which is considered better than denatured alcohol as it gets rid of water and cleans injectors.

It is an oxygenated fuel
Denatured alcohol, also known as methylated spirits, metho, or meths, is ethanol with additives that make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage recreational consumption. It is used as a solvent and as fuel for alcohol burners and camping stoves.
The term 'denatured alcohol' refers to alcohol products adulterated with toxic and/or bad-tasting additives, such as methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone. These additives make the alcohol unsuitable for human consumption. The most common additive used is methanol (5-10%), which gives rise to the term 'methylated spirits'.
Denatured alcohol is used as a lower-cost solvent or fuel for home or industrial use, compared to heavily taxed pure alcohol and alcohol used in beverages. It is also used as a gasoline additive to clean engines. Denatured alcohol is ethanol, and it is already in E10 fuel. Ethanol is a renewable fuel made from various plant materials, and it oxygenates the fuel. More than 98% of U.S. gasoline contains ethanol, which reduces air pollution.
Ethanol is also available as E85, or flex fuel, which can be used in flexible fuel vehicles designed to operate on any blend of gasoline and ethanol up to 83%. Another blend, E15, is approved for use in model year 2001 and newer light-duty vehicles. However, ethanol can affect some of the materials in fuel injection systems, such as swelling and corrosion of elastomer-type seals.
