Putting Coca-Cola into the gas tank is one way to ruin a car engine completely. But it depends on the amount of soft drink in the car gas tank. Not only Coca-Cola, but any soft drink pouring a significant amount into the gas tank can also ruin your car engine completely.

What happens when you put Coca-Cola in a gas tank

The answer is: What happens next is very predictable; Coca-Cola clogs up an engine, which will ruin your engine. When Coke’s chemical composition is mixed with the gasoline in a car, it might turn the whole mess into a caustic sludge that would clog up an engine. That’s why Coke or any soft drinks might damage your car engine.

What to do if Coke in your gas tank

If you drive your car with Coke in a gas tank, you first need to go to a repair shop or a professional car mechanic. They will check your vehicle and tell you how much damage is to your car engine. And, this might cost you a lot.

Fortunately, You could tell if someone put Coke in your car’s gas tank by the fumes of your car. The car emits a high amount of fumes as it should. Check out the exhaust gas or fuel gas; if it looks neutral to you, then you should check your car gas tank.

2. Water in Gas Tank

Water in the gas tank will damage the car engine. This is unusual, huh? It seems very normal, but something like water can ruin a car engine and put you in great danger on the highway. Water in the gas tank disables a car from running fast.

Mixing water into the fuel will detach the engine from the engine mount. Imagine you are unaware and keep driving. A few moments later, the car runs smoothly and then gets stuck again; this happens repeatedly. After that, the car stopped in the middle of the highway. Undoubtedly Nobody wants to be part of this experiment, I believe.

We know that most of the time, we wash our car with water. Although, you can clean the engine without water. So, whenever we wash a car engine, we need to be careful, especially if we have a child like me.

How Much Water in a Gas Tank Will Ruin a car?

A full cup of water or more can damage a car’s engine. Even a small amount of water might be a significant and serious problem for your car engine. That’s why you should be aware of putting water in a gas tank.

How to tell water in the gas tank

As you know already, water in gas tanks brings a great deal of damage to your car engine. Now let’s know symptoms of water in the gas tank:

  • Misfires
    Misfires can let you know you have to carry water in the gas tank. The water goes into the combustion chamber of the cylinder, and that’s why your car will misfire.
  • Rough Acceleration
    Rough acceleration is the most common sign when you have water in the gas tank. You often notice rough acceleration.
  • Check Engine Light
    By checking the engine light, you can tell you have water in the gas tank.
  • Rough Idle
    Rough idle. This is an easy way to tell water in the gas tank. The car engine is susceptible to idle for minor mistakes, and it is at idle you will notice quickly.

What to Do If You Have Water in The Gas Tank

It is important to know first if you have water in the gas tank. Otherwise, water in the gas tank can ruin the car engine.

  1. Displacement
    If you have water in the gas tank, displacement is the best way to remove the water because it will remove the old gas and replace it with high octane fuel as fast as possible.
  2. Replacing the Gas
    Replacing all of the gas from the gas tank is the easiest solution. But replacing the gas might not be the cheapest method because it is a waste of fuel.
  3. Get help from a Professional
    A professional is the best way to know the problem and get the proper solution whatever happens in a car. Water in gas tanks is not a simple issue. So, getting a professional mechanic is always a great way to water the gas tank.

3. Put Too Much Oil

Whether the low level of oil or too much level of oil in a car, both situations are not applicable for your car engine. Too much oil in a car can ruin a car quietly but permanently. When you put excessive oil in a car, this will allow hydro lock a car’s piston. The car’s piston needs both air and oil to operate the engine; a combination of air and oil is necessary to keep moving.

If you put too much oil in a car, the position can’t compress the oil, and eventually, excessive oil will make the position bend or break. By putting too much oil in a car, you can ruin a car without getting caught. That’s why we always see car manufacturers mention several times to avoid putting extra oil in a car in the car user manual.

4. Bleach in Gas Tank

Bleach in car gas tank

If you drive a car with bleach in the gas tank, your car is in great danger. If Bleach stays inside the engine part and fuel system for a long time, the Bleach will corrode and destroy the metal and rubber part. Bleach’s effect is corrosion will be faster than normal.

Destroying an engine with Bleach is common knowledge about damaging a car engine. With Bleach, you can ruin a car engine undetected.

Don’t put Bleach in the gas tank; this is extremely dangerous for any vehicle. It is a complete disaster. Bleach is mainly made out of water, and with a small amount of chlorine, these two ingredients make Bleach caustic and corrosive.

Furthermore, Bleach will rust several parts of the engine and corrode the whole engine. As we know, you can fix flooded car engines, but it is hard to fix a damaged car engine. Most of the time, the engine needs to be replaced.

5. Salt in Car Gas Tank

Too much salt in the gas tank will slowly corrode the bottom of the gas tank. When salt mixes with the gasoline, The salt crystals are going to slip into the fuel pump, and it is obstructing the filter, then the engine might not run. Another thing you might face is that the car might get hot and won’t start.

Salt would not damage a car engine that much compared to other ingredients, but this little ingredient can cause massive loss if this sustains in a gas tank. The engine will lose power, and salt corrodes the tank.

6. Sugar in Gas Tank

Sugar in car gas tank

Sugar in gas tanks turns its fuel into surgery petroleum. Sugar does not dissolve in the gasoline so that the Sugar will clog up the fuel filter. When Sugar gets passed through into the fuel tank, Sugar will sit at the bottom of the gas tank. And screws up your car engine and the car gas tank.

If you destroy the car engine completely without getting caught, this little thing is very useful. Not only Sugar, but there is also so much stuff related to Sugar like sweet sticky liquid, honey, molasses, waffle syrup, and more that is made out of Sugar.

If you have Sugar in the gas tank, you have to clean the filter, fuel pipe, and the other engine part of your car. This is necessary to remove their traces from the system.

What are the signs of Sugar in your gas tank?

Most vehicles have a sufficient fuel filter which prevents Sugar from making its way to the car engine. If you seem to have Sugar in your gas tank, then here are the common symptoms.

  1. Engine stalls
  2. The fuel pump will fail consistently
  3. Car won’t start
  4. Poor engine performance (that you will notice when you drive)

Sugar does not dissolve in gasoline; Sugar settles to the bottom of the gas tank instead. And eventually, clog up the engine.

7. Urine in Gas Tank

Urine in a gas tank depends on how much urine is in the gas tank. A small amount of urine in a gas tank is not going to damage anything. The small amount of urine is like pouring a glass of water. But huge amounts of urine are obviously bad for gas tanks.

This is funny. Right, Basically anything other than gasoline can destroy your car engine. Urine is also a thing that can harm the car engine not so rapidly but slowly. So if you notice or it happens to your car gas tank, you have to clean the gas tank’s filter and fuel pipe.

8. Brake Fluid in Gas Tank

Can Brake Fluid damage the car engine? Yes, absolutely, there are no chances to avoid this stuff. Brake fluid ruins a car engine and can put you at a great risk if the brake fluid level is full to your car gas tank.

As we know, Brake fluid is a type of hydraulic fluid used in hydraulic brakes and hydraulic clutches in vehicles. So, keep checking brake fluid level, then you can avoid the car engine and yourself from the great danger.

9. Hydrogen Peroxide in Gas Tank

Hydrogen Peroxide in a car gas tank will boost your car’s power and make the car so fast. When This ingredient is mixed with gas, it is like NOS. Mixing of gas and hydrogen peroxide increases the burn rate and puts the engine at a high temperature. When Your car engine gets a boost of power, then burns up and destroys the engine.

10.  Wrong Fuel in Tank

Wrong fuel in the gas tank, this happened with many people. Don’t start the engine if you notice during or after filling up the gas tank with the wrong fuel. If you start the car engine with the wrong fuel, you and your car could be at risk.

Wrong fuel in gas tank
Accidentally, Wrong fuel in gas tank

You would not be able to remove all of the fuel from the tank. For this reason, I always recommend getting help from the nearest car mechanic.
