What does the term “fuel gauge” indicate?

The term "fuel gauge" specifically indicates the level of fuel in the vehicle's tank. It serves as an essential instrument on the vehicle's dashboard, allowing the driver to monitor how much fuel is available for the engine to use. This provides vital information for planning refueling stops and helps prevent running out of fuel while driving.

Monitoring the fuel level is crucial for the efficient operation of the vehicle. If the gauge indicates a low level, the driver knows it's necessary to refuel soon to ensure that the vehicle remains operational. Understanding the functionality of the fuel gauge can also contribute to better fuel management and overall vehicle maintenance.
