Acetone in a Gas Tank: What REALLY Happens?! (explained) (2023)

If you have a car and plan to put acetone in the tank, you probably want to pass the emissions test. Some people claim that acetone works by cutting emissions in half. However, you may wonder whether such a claim is justified. So you may ask:

If you put acetone in a gas tank, what really happens?It is not true that acetone halves emissions. What really happens is that acetone can damage your engine by causing corrosion. Additionally, putting some in your gas tank can lead to poor engine performance. It can also affect the rubbers in your vehicle over time.

Acetone is a substance used as a paint thinner and nail polish remover. So it can cause corrosion in your engine if you put some on. While it can remove rust from your engine, it can also affect the internal structure in the long run. So it's not a good idea to go ahead with your plan to put some acetone in your gas tank.

In this article we show you all possible effects of acetone in your gas tank and your engine. This way you will be aware of all the risks and drawbacks and know how to deal with them if it ever happens to you.

Without further ado, let's get into it!

Acetone in a Gas Tank: What REALLY Happens?! (explained) (1)

What happens when you put acetone in your gas tank?

Putting acetone in your gas tank puts the overall health and performance of the engine at risk. The thing about acetone is that it has a high tendency to corrode and it can cause too much flame burn.

Another thing to note is that acetone doesn't do much to affect an engine's performance. It is therefore not a good idea to do something in your aquarium with all the associated disadvantages.

Aside from its minimal impact, acetone is also highly corrosive. So if you put some in your gas tank often, your engine will deteriorate and wear out.

Acetone should not damage the rubber by melting it. In the long run, however, it can cause degradation.

For all of these reasons, it's best not to use acetone at all and put it in your gas tank. It will not improve your engine's performance and may even affect your engine's health.

Can I use acetone to clean the gas tank?

The short answer is yes. You can use acetone to clean your gas tank. However, it is not a good idea to do this.

Since acetone is more of a paint thinner and nail polish remover, it has a very corrosive property. So it can also deal with the rust formation in your petrol tank. So if you put a gallon of acetone in your tank it may be enough to shake off the rust.

However, you should be aware that while it can help you deal with rust, it can cause other problems to your engine.

For example, if the acetone mixes with the fuel, it can lead to corrosion and fuel combustion.

Since acetone burns more than fuel, it seems to increase efficiency. However, that is not the case.

The acetone would cause inefficient combustion. What's more, it can even corrode any rubber in your engine that it touches. So while it's not true that acetone melts rubber, it can still break down.

Will acetone clean fuel injectors?

Acetone cleans fuel injectors and even valves, and that's because of its solvent properties. However, it is only necessary if the engine is running on low quality oil or fuel. It also works for an engine that has not been properly tuned for a while.

If you have an engine that runs on good quality petroleum products, you will not necessarily reap its benefits.

The point is that while acetone would clean your fuel injector due to its solvent properties, it can attack the internal structure of your engine by causing corrosion.

For this reason, it is best not to use acetone and simply take your engine to an auto specialist for better cleaning.

How much acetone do I put in my gas?

If you plan on putting acetone in your gas tank or mixing it with your fuel, you should first understand the risks. However, if you still want to go ahead, you can mix about 2 to 5 ounces of acetone for every 10 gallons of fuel.

It's a safe ratio to follow to protect your engine from damage. The amount of acetone should be enough to clean both your fuel injector and your valves.

Still, we recommend that you stop using acetone as it can wear out your engine in the long run.

Can Acetone Damage Your Engine?

As mentioned earlier, acetone can damage your engine by causing corrosion and making your engine perform poorly.

While putting in acetone might seem promising for any user, it's not a good idea because of its corrosive properties.

Car manufacturers disapprove of it and warn users against using acetone as it can cause wear and tear on the internal structure and also cause the deterioration of the rubber in your engine.

If you think it will help your engine, it won't give you much performance improvement. Furthermore, it can even cause your engine to wear out in the long run.

Acetone in the gas tank to pass on emissions - How does it work?

Some people claim that adding acetone to the gas tank is ideal for users to pass the emissions test for their car or any other vehicle.

Some claims state that 1.5 to 3 ounces of acetone for every 10 gallons of fuel can have the following benefits:

  • Reduce your engine's emissions by half
  • Improve the performance of your engine
  • Improve your gas mileage

However, it is not a valid claim and there is no supporting evidence to prove it. Additionally, while acetone can work well in cleaning your engine by removing rust, it can also cause corrosion in the long run.

Furthermore, it can also cause the rubber materials of your car to degrade with regular use. So while the acetone won't melt your rubbers, it can still affect them in the long run.

For this reason, you may want to consider other things and tips for passing emissions testing for your engine.

As always, take as a rule of thumb not to use acetone in your gas tank for any purpose. This way you can prevent any problem and maintain the health of your engine for long periods of time.
