Common fueling mistake can cost drivers dearly

Many drivers unknowingly risk damaging their vehicles and wasting money by continuing to fill their gas tanks after the pump automatically shuts off. This common practice, especially before long trips, can lead to significant repair costs.

When the fuel pump nozzle clicks off, it signals that the fuel tank is full, even if it appears there is room for more. Topping off the tank beyond this point can cause excess fuel to be expelled through the overflow system, meaning the driver pays for gasoline they cannot use. Additionally, spilled fuel can damage the car's paintwork, leading to further expenses.

A more serious consequence involves the car's vapor recovery system. During refueling, vapors are released, and the added pressure from overfilling can damage the activated charcoal filter found in many modern vehicles. This damage can result in irregular engine performance and necessitate expensive repairs.

To avoid these issues, drivers are advised to stop refueling once the pump automatically shuts off. This simple practice ensures that fuel is not wasted and prevents potential damage to the vehicle's sensitive components.
