In the winter, the amplitude of temperature change is quite large. If the temperature fluctuates a lot, you have a risk of condensation in the fuel tank (creates water in fuel tank). If water gets into the engine, the fuel system or the filter may cause undesired operation of the motor vehicle. Therefore, it is wise to avoid driving with half-empty tank in the winter and to keep the tank as full as possible.

Diesel-powered car owners must ensure that the fuel would be enough for the cold and the fuel is suitable for use even when the air temperature drops significantly. In addition, it is important to check the quality and origin of the fuel, because the use of heating oil mixed with diesel fuel can damage the engine of the vehicle.

In addition, it is also advised to keep the tank full in the winter because if the car should break down or is stuck in the snow, you can warm your car comfortably while waiting for help.
