As we all know, your car’s engine works on fuel and therefore, you need fuel to start the car. However, if your car won’t start at all, there might be some water present in the fuel tank.

Usually, the water in the tank needs to be above the piston that is inside your car’s cylinder. This means that the piston won’t be able to complete the rotation and therefore, you can’t start your car at all.

If you notice this kind of problem, it is recommendable to check the fuel tank and see if there is any trace of water in it.

2) A Decrease in Engine Power



If there is water inside your fuel tank, your car will lose its engine power. However, this is a bit harder to notice since your car’s engine will lose its power slowly over time.

Anyhow, you will definitely notice that something is not right with your car as the vehicle’s mileage is going down. In that light, you should always check for the water in the fuel tank since you don’t want to damage your engine.

The whole process of decreasing engine power of your car will start because of bio degradation of the fuel, which will decrease your car’s power.

3) Acceleration Problems
