Effective methods for combating water in fuel

If water gets into a car's fuel tank, it can lead to serious problems: difficulty starting the engine, loss of power, and even its stalling.

What you should know

One of the main reasons for the appearance of water is condensation, which is formed due to temperature changes. During the warm season, moist air accumulates in the tank, and at night it cools down, causing condensation on the walls. Water can also enter through ventilation valves, a poorly closed or damaged filler neck, during car washing or with poor-quality fuel at the gas station. This is especially true for diesel fuel.

You can get rid of moisture with the help of special additives that bind water and allow it to be burned safely. They are recommended to be used in the fall, before frost sets in.

If there is a lot of water in the tank, the fuel should be drained through the drain plug (if there is one) or even the tank should be dismantled. In difficult cases, the system must be flushed and dried. If the water has penetrated further, the fuel filters should be replaced, as they are the first to suffer from contamination.
