Where does the water in the fuel tank come from?

There are only two reasons for the water appearance in the tank:
1. Water can get in with low-quality fuel.
2. During the off-season and in regions with a humid climate, condensation may form in the fuel tank due to temperature changes.

Condensation is formed due to the temperature difference between the air (in which moisture is always present) and the fuel. Water accumulates at the bottom of the tank in the area of the fuel pump. Therefore, it is desirable to minimize the amount of condensate.

To avoid this problem, it is necessary to fill a full tank, and not drive “on the leftovers”. The less air in the tank (and, accordingly, the more fuel), the less condensate forms.

We also urge you to carefully monitor the quality of the fuel that you choose for your car. All filling stations must have a quality certificate for each type of fuel not older than 7 days.
