During operation, there are many reasons that can cause a car to become contaminated with water in the fuel system, such as refueling at a gas station with poor quality, driving into a flooded area…
When gasoline is contaminated with water, the operating power of the fuel pump system gradually decreases because it is not lubricated during operation. In addition, water also causes the fuel tank to be prone to rusting due to its higher weight, which will settle at the bottom of the tank. If the condition of water-contaminated gasoline is not promptly addressed, the fuel system can easily be damaged.

Signs of gasoline contaminated with water
The most basic sign to identify gasoline contaminated with water is a decrease in performance, engine stalling, or the inability to start the vehicle.
When gasoline is contaminated with water, this mixture is sent to the combustion chamber, causing vapor lock phenomenon, unlubricated pistons will be stuck or difficult to move within the cylinder, thus the fuel intake, compression, ignition, and exhaust processes cannot be carried out.
In severe cases, the engine can be damaged due to water-contaminated gasoline, and the owner will have to spend a large amount of money on repairs to get the vehicle back to normal operation.
In addition, when the vehicle is in operation and the acceleration is not smooth, it is necessary to check if the fuel system is contaminated with water.
How to handle gasoline contaminated with water?
When detecting that gasoline is contaminated with water, the user must stop the vehicle and take it to the nearest repair garage, drain all the water-contaminated gasoline in the fuel tank and replace it with fresh fuel to ensure quality. Users should choose gasoline that does not contain ethanol as this type of gasoline does not absorb water.
The fuel filter plays a major role in preventing water from entering the vehicle’s fuel tank. Therefore, in cases where the water content in the gasoline is too high, it is necessary to replace the entire filter.
To avoid and limit the occurrence of gasoline contamination with water, owners should not refuel at gas stations with poor quality, avoid passing through deep flooded areas, and should not spray water into the engine compartment when washing the vehicle.
