How far can you drive when the fuel gauge is empty?

When the fuel warning light on the dashboard comes on, you can typically drive about 30 kilometers. Relevant information is as follows: 1. The working principle of the fuel gauge is: When the fuel tank is full, the resistance value of the variable resistor connected to the float decreases, causing the circuit current to reach a higher value, and the fuel gauge needle points to a higher position. As the fuel level decreases, the resistance value of the variable resistor increases accordingly, reducing the circuit current, and the fuel gauge needle also drops. 2. The function of the fuel tank: The main function of the fuel tank is to store fuel. Additionally, it helps dissipate heat from the fuel (or retain heat in colder environments), release gases mixed in the fuel, and allow impurities in the fuel to settle.
I've been driving for over 20 years and have encountered the fuel gauge hitting empty many times. Actually, the distance each car can travel after the fuel light comes on varies greatly. Japanese cars can generally last about 50 kilometers, while German cars might stall after just 30 kilometers. Last month, I remember driving my old Accord and managing to go 48 kilometers after the fuel light came on before I could refuel. However, you really shouldn't rely on this too much, especially in summer when using air conditioning, as fuel consumption skyrockets. Once on the highway, my fuel light came on with 15 kilometers left to the service area. I turned off the AC and opened the windows to save fuel, nearly stalling in the last 500 meters. My advice is to immediately navigate to the nearest gas station when the fuel light comes on, rather than stressing your engine and yourself like I did.
