How to Read the Car Fuel Gauge?
2 Answers
Here are the methods to read the car fuel gauge: 1. The pointer-type fuel gauge indicates the amount of fuel through the position of the pointer. The gauge is marked with two letters, E and F, where F stands for full and E for empty. 2. The digital-type fuel gauge shows the remaining fuel through the number of illuminated bars. More illuminated bars indicate sufficient fuel, while only 1 to 2 bars mean the fuel level is low and needs to be replenished promptly. Below is how the fuel gauge works: Generally, there is a fuel pump in the fuel tank. The computer controls the extraction of fuel and transports it to the engine. A float is installed on this fuel pump, which is connected to a sliding resistor. As the float moves up and down in the gasoline, the change in liquid level alters the resistance, sending different electrical signals to the engine computer.
Checking the car's fuel gauge is actually quite routine. Every time I start the car, I habitually glance at the dashboard where there's a small icon, usually shaped like an oil can or an oil drop. It displays bars or a percentage number—full bars indicate sufficient fuel, while empty means it's almost out. I drive an ordinary sedan with relatively high fuel consumption, so I often combine it with the remaining mileage display to predict when to refuel. Don’t wait until the yellow fuel warning light comes on, as that means the fuel level is critically low, which could lead to stalling or engine damage. Since developing this habit, I’ve never faced the embarrassment of running out of fuel. Modern cars also integrate with apps, and I find it convenient to check real-time fuel levels on my phone. On long trips, checking the fuel gauge every hundred kilometers adds extra peace of mind.
