What To Put In Gas Tank To Ruin Engine?

Currently, many people have asked the question of what to put in gas tank to ruin engine. Most of them think that the best way is to use mechanical force to destroy them.

But they don’t know that the gas tank is the weak point of all vehicles. You can pour anything into the gas tank (except gasoline) to destroy the car engine. The following article introduces you to some materials that damage the engine quickly.

What To Put In Gas Tank To Ruin Engine

Many objects have now been proven to harm a car engine when placed inside the gas tank. Specifically, if you put anything other than gasoline in the gas tank, it will cause engine damage. You can use some of the following materials:

  • Water
  • Sticky liquid
  • Salt
  • Street
  • Brake fluid
  • Coke
  • Hydrogen peroxide
  • Bleach

Most of these substances will clog the fuel transmission system and disable the engine. For chlorine bleach, your engine can be strongly corroded, causing punctures in some places.

How To Use Each Type Of Material To Destroy The Engine?

When you pour Coke into the car’s gasoline tank, its chemical composition will react with gasoline to form residues that increase engine congestion.

Besides Coke, almost all soft drinks can react with gasoline to destroy car engines. The way to detect Coke in the machine is to rely on the car’s smoke. Your car will appear with a lot of smoke with an unpleasant smell.

So what to do when there is Coke in the gas tank? The best way is to go to a repair shop or an experienced car mechanic. They will conduct an inspection and notify you of the extent of the engine damage.

To fix this problem, you can lose a lot of money because the composition of Coke reacts very strongly with gasoline. Therefore, most engine damage is very severe. You may have to replace the engine unit.


If you want to destroy the engine and save money, you can use water. Most people mistakenly believe that water is harmless.

But NO, water has a powerful ability to destroy car engines. When you add water to gasoline, the engine will separate from the engine mount, and your car will immediately stop abruptly.

So how to determine if there is water in the gas tank? You can rely on the following signs:

Wrong fire: This is a phenomenon where your car will not be provided with enough fuel to operate. Because water has replaced part of that fuel as it moves into the cylinder combustion chamber.

Acceleration decreases: When water is in the engine, your car will have a sudden loss of throttle or lack of power. You will feel it when you are the driver.

Check Engine Light On: When you see the check engine light on, your engine is likely having water or some other problem.

Use bleach for the fuel tank

Bleach is the next option that you can consider when you want to destroy the engine. When used, the eraser will damage metal parts and the rubber inside the machine because it contains Chlorine – a powerful, corrosive detergent that punctures the surface.

At that time, fuel will leak out, and you will not control the amount of gasoline left in the car. In addition, if bleach is present in the gas tank, it will be hazardous for the driver. Because it can cause a car fire at any time.

Use salt

When mixing salt in gasoline, the salt crystals fall into the fuel pump hose and clog the filter. Then your car will not be able to start.

Although salt does not cause much harm to the engine, if it appears in the fuel tank, it will cause many other negative consequences. An example is a reduction in engine power.

You can refer to the article bypass reduced engine power to better understand the effects of reducing engine performance.

Brake fluid in the fuel tank

Brake fluid is the next liquid that can damage your engine. It can put you at significant risk if the brake fluid level reaches your car’s gas tank.

By nature brake fluid is the hydraulic fluid used in the vehicle’s hydraulic brake and clutch system. It has no effect as a fuel in the engine. When the brake fluid is mixed with gasoline, it will form a non-flammable compound, affecting fuel conversion into energy.

Hydrogen peroxide in the gas tank

Hydrogen peroxide in the gas tank will increase your car’s outstanding acceleration.

When this substance is mixed with gas, it will create a mixture of NOS that helps increase combustion and puts the engine at high temperatures. When the car engine increases power, the gas mixture will ignite and destroy your engine.

Some Frequently Asked Questions

Will bleach in a gas tank ruin an engine?

The answer is yes. Because detergents containing Chlorine are a caustic and corrosive oxidizing agent.

When it comes into contact with the tank wall, it will erode the wall surface, causing puncture and fuel leakage to the outside. At that time, you can be turned off at any time due to not controlling the actual fuel level of the car.

How do you secretly disable a car?

You can use one of the following ways:

  • Disconnect all battery cables
  • Turn off the fuel system
  • Turn off the air filter
  • Remove fuse ECU
  • Remove spark plug wire

What Happens If You Put Antifreeze In Gas Tank?

Antifreeze is a yellow or greenish liquid that circulates through a car’s radiator and draws heat from the engine.

If antifreeze is mistakenly poured into the fuel tank, it will have inevitable consequences. It can cause damage to the car and prevent the engine from starting. You need to take the car to a repair center to have the substance removed.


Hopefully the article will help you have the necessary information of what to put in gas tank to ruin motor. You can use one of the above methods by introducing substances that cause engine damage to the fuel tank.

To save costs, you can use salt, sugar, or water to destroy the engine. However, consider this job because you will have to pay a considerable fee for repairing and replacing the engine if the motor fails.
