Things that should never be put in a gas tank include the following seven abominations: Let’s get this show on the road.

What’s The Worst Thing To Put In Someone’s Gas Tank?


salt in gas tank

The bottom of the gas tank can corrode if you add a lot of salt to it. The salt crystals will be slipping into the fuel pump if the salt is combined with the gasoline. The filter will become clogged if this occurs.

Thus, the engine may no longer be able to run. In addition, the car may overheat. While salt doesn’t have the same corrosive effects as bleach, it can nevertheless cause harm to a vehicle.



Corrosive sludge will result if the chemical composition is combined with gasoline in the tank. The engine of the car may become clogged as a result of this. The motor of your car can be harmed by drinking Coke.

To ruin your car’s engine, put coke in your gas tank, but if you don’t want to harm your car’s engine, do not put coke in your gas tank. The extent of the damage is directly proportional to the amount of coke you use.

Coca-cola will quickly destroy your motor if you put it in your gas tank. Whether you smell your automobile, you’ll know immediately if there’s a problem. You’ll be able to tell that your car is emitting fumes.


The motor of your car will be destroyed if you add water to the gas tank. It’s dangerous to drive with water in your gas tank. A automobile that has water in its gas tank will not be able to go at a high speed.

Using water as a solvent can remove the engine mount from the fuel. When driving, you may lose control of the vehicle if you are not aware of this.
After a while, you may find yourself unable to control your vehicle. You could get into an automobile accident if you do this. Always keep an eye out for anything out of the ordinary when driving.


To transform gasoline into surgical petroleum, put sugar in the tank. There is no melting of sugar in the gas. Sugar will get stuck in the fuel filter if you do this.

Fuel tanks and engines can both be damaged if sugar is allowed to enter and travel through them during transportation. In the case of a car’s engine, this can be extremely useful. Sugar isn’t the only culprit here.

The engine of a car can be damaged by any liquid that includes sugar. Honey syrup and a slew of other high-sugar concoctions can have the same effect.
You’ll need to clean your engine’s filter, fuel line, and other components to remedy the situation. This is important in order to flush the system of any sugar that may be present.

Driving a car with bleach in the gas tank is extremely risky. Bleach can cause corrosion and rust to the car’s engine and mechanical parts if left in the gas tank for an extended period of time. Bleach is a common tool used to obliterate an automobile’s engine.
An engine can be severely damaged by it. Bleach, which contains ninety percent water, can damage an automobile’s engine. The outcome is nearly same.

Bleach should never be poured in your gas tank for any reason. First, the automobile will operate, but if the gasoline sensor stops working and it begins to consume bleach, it will no longer run. Damage to your car’s engine will be serious, and the cost of repairing it will be high.


If you put too much urine in the gas tank, you’ll do more harm than good. If there is only a small volume of pee, it may not cause any harm. If a gas tank is filled with a large number of urines, the tank can already be damaged.

Gas tanks don’t like having a lot of urine in them. Slowly, but surely, your car’s engine will be harmed by this.
The gas tank’s filter and fuel pipe will need to be cleaned if this occurs. That you have to see a mechanic is the worst part of the whole situation.


A gas tank is absolutely necessary. Gasoline is the only thing allowed in the gas tank.

The car and its engine can be damaged if the gas tank is not only filled with gasoline but also with other liquids.
