What Happens When You Gas Up with the Car On?
When you gas up with the car still running, several things can happen, and it’s essential to understand the potential consequences. Here’s a breakdown of what might occur:
The Immediate Effects
When you start pumping gas with the car on, the fuel pump will begin to dispense fuel into the tank. However, the fuel level sensor may not accurately detect the fuel level, leading to potential issues:
- The fuel level sensor may become confused, causing the fuel gauge to malfunction.
- The car’s computer may receive incorrect fuel level data, leading to potential engine stalling or misfires.
The Long-Term Consequences
While the immediate effects might seem minor, the long-term consequences of gassing up with the car on can be more severe:
- Incorrect fuel level readings can lead to premature wear on the fuel pump, potentially causing it to fail prematurely.
- The car’s computer may become desensitized to the incorrect fuel level data, making it more challenging to diagnose issues with the fuel system.
- In extreme cases, the incorrect fuel level data can cause the car to stall or even fail to start, potentially leaving you stranded.
