  1. How Can Sugar Ruin a Car Engine?

Now, for those who want to know what happens when you put sugar in a gas tank, a small quantity of sugar in the gas tank can render the engine inoperable. Though you can clear a minor quantity of sugar, a high amount can destroy the machine, and you might need to replace the machinery. 

This is because the sugar does not dissolve in the gasoline; instead, the granules of sugar float in the tank as the gas is added. They clog up your fuel filter and spread it all over the bottom. As a result, the gasoline faces difficulty in reaching the engine and propelling the vehicle. Furthermore, if sugar grains collect in one location of the car, that can cause more damage. 

Sugar normally collects in three locations: the gas pump, the gasoline injector, and the gasoline filter. 

How to Tell if There Is Sugar in the Gas Tank?

  • Stalled engine

  1. Hydrogen Peroxide 

It is the most dangerous liquid to pour into your vehicle’s gas tank. Not only can this liquid cause substantial damage to your engine, but it can also ignite the engine and cause the vehicle to explode. Hydrogen peroxide is added to the car’s gas tank to improve the speed and power of the vehicle. However, it becomes highly hazardous when it comes into contact with gasoline. 

When hydrogen peroxide is combined with gas, the gasoline burns and supplies fuel faster than it usually does on its own. However, your engine can only bear the speed and power to a certain limit before it wrecks completely. 

If there is a small amount of hydrogen peroxide in your car’s tank, you can repair it. However, if a significant amount of hydrogen peroxide enters the car’s gas tank, you will have to replace the vehicle. 

How to Tell if There is Hydrogen Peroxide in the Gas Tank?

The easiest way to determine if there is hydrogen peroxide in your gas tank is to look inside. This material is heavier than gasoline and sinks to the tank’s bottom. Moreover, its subtle blue hue makes it even easier to recognize. If you notice even a tiny amount of hydrogen peroxide in your tank, take your vehicle to the mechanic. 

Final Thoughts 

The above points clear the query of “how to ruin a car engine.” As a car owner, it is essential for you to be aware of what you should never put inside your vehicle. Any liquid, such as food items or hazardous material, can wreck your engine. 

If you stick to the usual gasoline for your gas tank, your engine will stay clean for many years. Anyone who handles cars should be careful of materials that can be highly flammable and cause serious threats if not handled properly. 

Therefore, keep toxic materials out of your gas tank. By staying alert and staying cautious you can save money and protect your vehicle from heavy damage.
