For some, the mere sight of the fuel warning light triggers panic, indicating that only 10 to 15% of the reserve remains. Others, however, make a routine of nearly depleting the tank before refuelling. Regardless of the motivation, driving on reserve is never a wise decision.
As highlighted by Turbo.fr, this practice not only puts you at risk of running out of fuel but also inflicts damage on your engine. Fuel pumps require a consistent flow of fuel for optimal performance. When the tank enters reserve, more air is introduced into the pump, reducing lubrication, causing overheating, and accelerating wear and tear.
In the long run, this can lead to pump failure, a component that often comes with a hefty price tag.
Another peril is the potential for clogging. The fuel pump contains a filter that can quickly accumulate dirt if you consistently drive with a low fuel level. Dirt tends to settle at the tank’s bottom, posing a threat to the pump’s functionality.
Winter adds another layer of risk, particularly for diesel vehicles. As highlighted by RTL.fr, extremely low temperatures, nearing -10 degrees, can cause diesel fuel to freeze, especially if the vehicle remains parked for an extended period. Condensation, resulting from temperature disparities between the warm tank interior and the cold exterior, can contaminate diesel fuel. In small quantities, this water can easily congeal, leading to filter clogs.
Experts strongly advise maintaining a tank level of at least a quarter full at all times to safeguard against these issues and ensure your vehicle’s optimal condition.
