How to Disable a Car Through the Gas Tank? 9 secret ways no one knows

There are a few different approaches one might use in order to wreck an engine. It may sometimes be feasible to completely wreck the engine without any traces of the damage being left behind. If you were to put sugar in the gasoline tank, for instance, it would not dissolve, and the resulting substance would be a thick sludge that would clog the fuel filter. Other approaches, such as the addition of water, could be more subtle.

Adding bleach to the gas tank is one of the most effective methods to completely destroy an engine. Because of the chlorine in this solution, the engine will corrode. On the other hand, if you want to ruin a functional engine, you should use a different kind of liquid. A substance known as sodium silicate may be used to destroy the engine without leaving any traces behind.

In this article, we will be discussing “how to disable a car through the gas tank” and the various ways in which a person can secretly ruin a car’s engine. So, let’s get started.

Destroying a Car’s Engine –  What’s the Best Thing to Do?

If you put anything in the gas tank of a vehicle that isn’t gasoline, you run the risk of causing irreparable damage to the engine. The gasoline filter will get clogged if you put in any of the following: water, salt, sugar, sticky liquid, or any of a wide variety of other substances.

You could also put some cocaine, hydrogen peroxide, brake fluid, urine, bleach, or any number of other substances in your automobile, and all of these items, along with many more, will cause your car and its engine to suffer some harm. If you are dead set on destroying the engine of a car, you may choose anything you want and put it in the fuel tank of the vehicle. However, if you want the results to be as effective as possible, you might try combining bleach with gasoline, which will result in a disaster for the car’s engine.

However, you should keep in mind that this is a risky thing to do. If you want to put a significant amount of bleach in your gasoline tank, you should be aware of the potential risks and take appropriate safeguards. If you want to completely wreck your automobile, this is a strategy that will work extremely well.

If you put bleach into the gas tank of a vehicle, there is a chance that the car will start. Even if there is just a small amount of gasoline remaining in the tank, the car will still be able to go forward with that amount of petrol. However, if there is no gasoline left in the fuel tank and the only liquid that can be used is bleach, the car will suffer a variety of serious damage.

If you keep the bleach within the fuel system for an excessively extended period of time, it may cause corrosion and rust in numerous components of the engine. Bleach contains chlorine, which, if you didn’t already know, is a very corrosive oxidant. You should also be aware that chlorine is one of the ingredients in bleach.

Which Liquid Destroys the Car Engine?

As mentioned above, there is a wide variety of substances that may be poured into a gas tank in order to do irreparable damage to the engine. For instance, you may add some cocaine, urine, brake fluid, or any number of other things. Your vehicle and its engine are susceptible to harm from any liquid that is not gasoline. This includes any liquid that you spill on them.

Because water makes up ninety percent of bleach, putting water in a gas tank will have the same effect as using bleach. Additionally, it does significant damage to the engine of the vehicle.

9 Ways to Secretly Destroy a Car’s Engine

1. Pour Some Water

Seems perplexing? How can something as benign as water destroy an engine?

A piece of advice for you: anything that isn’t gasoline is terrible for an engine. It may come as a surprise to find out that more than 90 percent of bleach is water, yet the fact remains that it is hazardous to the vehicle’s engine.

If you keep driving without knowing what is going on, the car may act strangely.

2. Hydrogen peroxide

The power of the automobile may be increased by adding hydrogen peroxide to the fuel tank. It may help it drive quicker, but it may also cause damage to the engine of your vehicle. Depending on the amount of concentration it has on your automobile, it has the potential to completely damage it.

The addition of hydrogen peroxide to the gas causes an increase in the burn rate, which in turn causes the engine to reach a high temperature.

If you give your vehicle’s engine an increase in power, it will catch fire and break down completely. If you find hydrogen peroxide in the gas tank of your vehicle, you should immediately pull over and stop driving. However, if you have not yet begun driving, you should not start your vehicle in the event that you find hydrogen peroxide in the tank.

3. Wrong Fuel

If a person puts improper fuel in the gasoline tank, then there is an extremely high risk that the engine may be damaged. In the event that you discover that you have put the incorrect gasoline into the gas tank of your vehicle, you should not start the engine since your vehicle is at serious risk.

In the event that you accidentally fill the gas tank with the incorrect gasoline, you will need the assistance of a trained technician to flush the fuel system, including the fuel tank and fuel lines.

4. Inadequate Maintenance

Inadequate maintenance in general has the potential to inflict your car far more damage than almost anything else. Spark plugs that are not firing properly, low tire air pressure, low fluid levels, and incorrect timing are a few to be named.

Poor shock absorbers, rough roads, excessive engine revving, low-quality fuel, lack of maintenance, and excessive engine revving will all cut years off of the life of your expensive car.

5. Using Bleach

Adding bleach to the gas is just asking for disaster to strike!

Do not put it in your petrol tank unless you are suicidal or unless you have some other bizarre motive for wanting to destroy your car. In the beginning, the car will be able to run, but once there is no more fuel in the tank, it will come to a full halt.

If it stays in the fuel system for too long, it will corrode and cause different parts of the engine to corrode because it contains chlorine, which is a very corrosive oxidant.

6. Ethanol

The use of gasoline with ethanol is one of the things that will damage your vehicle’s engine, in the long run, the most.

It may make up 10% to 15% of the petrol that you purchase, and many industry professionals believe that the government will mandate gasoline makers to add more of it in the near future.

Ethanol is very hazardous since it may take on the properties of water and likes to break down polymers. If ethanol is not stored in the correct manner, it will develop a molecular link with water. This connection can cause corrosion in your fuel lines, injection systems, valves, rods, cylinders, and heads, as well as your crankcase. On the other hand, ethanol that comes into contact with rubber and plastic components of the fuel system leaches out of the polymers and breaks them down over time, which results in damage to vital components.

Fuel additives, such as coolant and oil, are no longer only recommended; rather, their use is now almost mandatory. Fuel additives are the only method to protect yourself and your car from cancer that is caused by ethanol buildup in the engine of your vehicle.

7. The Sweet Little Sins

If you are simply trying to be naughty and have no genuine intention of destroying the engine, you may use honey or any other sticky substance.

Sugar in a gasoline tank is a myth because it will clog the fuel filter exactly like pancake syrup, waffle liquid, honey, syrup, and other sticky sweet liquids. This urban legend began when someone put sugar in their gas tank. Sugar doesn’t dissolve in gasoline.

As a consequence of this, even if some of the sugar is able to get past the gasoline filter and into the fuel line, it will eventually fall to the bottom of the tank.

These chemicals won’t do significant damage to the engine, but over time they will disable it completely. You need to clean the filter, the fuel line, and the gas tank in order to eliminate any traces of them from the system.

8. Starts With A Bang

Almost every part of your car could be damaged by a cold start, including the battery, the starter, the inverter, the pistons, the cylinder rods, and the heads.

If you live somewhere where it gets below 0 degrees Fahrenheit more than once a week during the winter, you should buy an engine heater.

They are not only affordable but also quite easy to put on your radiator. They won’t hurt the engine and do a good job of what they’re supposed to do.

9. Sludge

Sludge will begin to accumulate over time if the oil is not changed regularly enough.

Within the confines of the engine, the oil is subjected to chemical reactions that cause it to be converted into a viscous, gummy sludge that accumulates in strategic areas.

It could stop oil from getting to parts of the engine that need it, and it could cause parts of the engine to hold on to too much heat, which could cause damage over time.

How to Check for Water in the Gas Tank?

In order to determine whether or not there is water in the gas tank, you will first need to be familiar with the typical symptoms associated with this problem. The presence of water in your gas tank may be determined by looking out for these six indications or concerns that may arise.\

1. Engine starting issues

When there is enough water mixed in with the gasoline, there comes a time when the vehicle’s engine will not even turn over. It’s possible that your vehicle’s engine is hydro-locked if it won’t even turn over. When the pistons in the cylinder attempt to exert control over the flow of water, they are unsuccessful because water cannot be compressed in the same manner that air can.

It will result in the engine being utterly unusable and may even cause damage to the internal components, such as the rods that make up the crankshaft. It is rare, and there must be a significant quantity of water present for it to take place.

2. Issues when the automobile is idle

Misfires and inadequate air-fuel mix are often the causes of a bumpy idle, which is another prevalent symptom. Idling the engine causes it to be more susceptible to making errors, and it is precise while the engine is idling that you will notice the most signs of having water in the gas tank.

3. Faulty acceleration of the vehicle

Slow acceleration is the single most common sign of all of the symptoms associated with water in the gas tank. Due to the fact that the car’s engine mistook the water for gas, the air-fuel ratio in the combustion chamber is going to be strange.

The car is equipped with a multitude of sensors, each of which works in unison to check that the ratio of air to fuel is at its optimum level at all times.

The sensors will provide an inaccurate reading if the engine is wet, which will cause the engine to run either excessively rich or excessively lower than it should. As a consequence of this, the power of the engine may be reduced, and you may see symptoms such as slow acceleration as a result of this.

4. Engine misfires

Because of the issues that we addressed when the water enters the combustion chamber of the cylinder, it is quite possible that you will observe glitches when the water reaches the chamber where the combustion takes place.

Misfires and severe acceleration are two common symptoms that are often mistaken for one another. This is due to the fact that misfires may cause harsh acceleration, but misfires might also be noticed while the vehicle is being driven

5. Steam releasing from the exhaust

The release of steam from the engine is triggered if there is water vapor present in either the combustion chamber or the exhaust pipe. When water is heated to a temperature of above 100 degrees Fahrenheit, it turns into steam.

If you notice that much more steam than normal is coming out of the exhaust pipe, this may be an indication that there is water present in the gas tank.

6. Engine lights blinking

Real-time analysis is performed on each and every one of the engine sensors included in modern automobiles. Imagine if one of the sensors finds that the readings are inaccurate. In this scenario, it will relay the information to the ECU, which will then store a fault code in its memory and, depending on the severity of the condition, may trigger the engine warning light to come on.

What Happens When You Put Sand Into a Fuel Tank?

If you put sand in the gas tank, it would have the same effect as if you added sugar or any stuff like that. It is important to note that there is a filter located in the gas chamber to prevent particles from entering the tank.

However, if you put in an excessive amount of sand, it won’t be as effective as it could otherwise be. Aside from that, the sand would make its way into the fuel tank and clog up the filter, which would lead to difficulties such as the inability to drive the vehicle or the engine stalling out or failing to fire properly when it was started.

It is possible for the engine to sustain harm if the tank is completely full with sand. Sand has the potential to be extracted with a lot less effort compared to other liquids. If your gas tank just contains sand, you may empty it by giving it a good scrub with some dish soap and water. Always bear in mind, however, that the procedure would still take a considerable amount of time, and that the sand would still constitute a threat to the engine’s general health.

  • Short-term consequences

The moment as you or another person poured the sand into a gasoline tank, the sand would get trapped in the engine, and you would immediately feel the impacts of this. Sand in the fuel tank might potentially cause the gasoline filter of a vehicle to get blocked. Sand may cause the engine to fail, stall, and finally die, making it unusable if this occurs.

  • Effects over the long haul

Sand may have a negative impact on an engine over time, particularly if it is allowed to accumulate unchecked and is not removed. Even while a tiny quantity of sand won’t create any big issues, it still has the potential to develop contamination in the fuel, which will lead to poor performance from the engine.

As a consequence of this, you should get in touch with a service professional as soon as possible if you have any reason to believe that your fuel tank contains sand. In this way, even if there are only a few sand grains left in the gas tank, you will be able to maintain the health of your engine and prevent future complications.

What Quantity of Sand Will Ruin a Gas Tank?

If there are just a few particles of a certain size, the gasoline and oil filter may be able to block them from entering the tank. However, if someone purposefully fills the tank up to the brim with sand, the engine might get jammed and eventually be completely ruined.

Some people believe that sugar and sand have clogged the engine. The reality is that none of these things will dissolve in gasoline.

How to Ruin an Engine Without Evidence?

What to put in gas tank to ruin engine? You may use whatever liquid you want in the gas tank, and as long as you do it in a stealthy manner, there won’t be any traces left behind. You might also try pouring some water into the gas tank, and there is a good chance that it will not be discovered.


The wrecked engine is something that nobody needs. Having said that, there are certain circumstances in which you might need to do so.

Your vehicle’s engine may be harmed by any of the approaches described in the section above.

Therefore, try out the different approaches on how to disable a car through the gas tank, and have fun doing it!

Frequently Asked Questions (FAQs)

How do you destroy a car in secret?

It is recommended that bleach be poured through the sunroof. Put sardines on the vent outside the vehicle, but make sure it’s hot outside. This will ensure that the only thing they smell when they turn on the air conditioner is the scent of hot sardines. We’ve tried everything, but we can’t seem to get rid of the smell.

What causes a car’s engine to stall?

An engine might freeze up for a number of reasons, including running out of oil, becoming too hot, or having a timing belt that is broken. Because of this, moisture-laden air from the surrounding environment is able to enter the engine via the air intake, continue on through the cylinder head, and condense on the cylinder walls, rings and piston surface.

What can the presence of bleach do to a gas tank?

Bleach is reportedly one of the most dangerous substances that may be poured into a gasoline tank. This is because it has the potential to react with gas compounds already present in the tank, which would result in the production of acid. The presence of the acid thus avoids premature corrosion of the tank and the fuel lines, which is one of the potential causes of the car’s engine to stall.

What happens when sugar is poured into the gas tank?

If there is an excessive amount of sugar in the system, it has the potential to block the fuel filter or the fuel injectors in the same way that any other material would. Because of this, it’s possible that the gasoline filter will need to be replaced, or the gas tank would need to be emptied first. This indicates that it is a malicious scheme that will cost you money, however, the amount won’t be nearly as high as if your engine were utterly destroyed.

What happens when you put anything other than fuel in the gasoline tank?

To deliberately cause damage to a vehicle’s engine without drawing attention to oneself, put anything in the vehicle’s gas tank. There are a number of different chemicals that may be put into the gas tank of a vehicle in order to fully destroy the engine. Because of the possibility that anyone has put anything in your fuel tank with the intention of wreaking havoc on your vehicle’s engine, you need to be informed of what to do in the event that someone does throw anything in your car’s gas tank.

Can urine in the fuel tank cause damage to the engine?

Urine is a substance that might potentially cause harm to a vehicle engine, but in a way that is slower and more subtle. Therefore, if you discover it or if it already exists in the gas tank of your vehicle, you need to clean the filter that is located within the tank as well as the fuel line.

What amount of bleach can damage the engine?

To ruin an automobile engine with bleach, you must first pour an adequate quantity of bleach into the fuel tank, then drive the vehicle for an extended period of time while the bleach does its work. In addition to that, you need to pour the whole gallon or bottle of bleach into the vehicle’s petrol tank.

If you discover that someone has put bleach into the gas tank of your vehicle, you should not start the vehicle; however, if you have already done so, you should cleanse the whole fuel system.

How to tell if there is sand in the gas tank?

Sand in the engine oil may make the vehicle’s motor jerky, cause it to stall, and even cause it to break down. Your vehicle’s performance may suffer if sand is allowed to accumulate in the gasoline tank.
