How far can a car go when it shows it's out of gas?

When a car shows it's out of gas, it can still run for about 40 kilometers. Here are some fuel-efficient speed measures you can take when the car indicates low fuel: 1. Reduce braking and idling, and avoid driving at low speeds. Braking itself doesn't consume much fuel, but slowing down and then speeding up again does. 2. Turn off electrical appliances such as navigation, radio, music, air conditioning, etc. These appliances have relatively high power consumption, which naturally affects the vehicle's fuel efficiency. 3. Drive at the fuel-efficient speed. Generally, the fuel-efficient speed is around 90 kilometers per hour. 4. It's best to keep the windows closed. If driving at the fuel-efficient speed, opening windows will undoubtedly increase wind resistance. Greater wind resistance means the vehicle faces more resistance, requiring more power.
It's really nerve-wracking when the fuel gauge shows empty while driving, and this is my biggest worry. Generally speaking, when the fuel gauge indicates empty, there's still a small reserve of fuel left in the tank, designed for emergencies, enough to drive about 20-50 kilometers, depending on the car model and driving habits. If the car has low fuel consumption, like driving in the city at slower speeds, it might last up to 50 kilometers; but on the highway, once you accelerate, fuel burns faster, and you might only get 20 kilometers before stopping. The risks are significant—when fuel is too low, the fuel pump can overheat and get damaged, costing hundreds to repair, and there's also the danger of suddenly stalling on the road, which could lead to an accident. Once, my fuel gauge showed empty on the highway, and I pushed it for 15 minutes, only to burn out the fuel pump, costing me over 500 bucks. I recommend not taking this risk—when the light comes on or the gauge is near empty, it's time to refuel. Develop a habit of checking the fuel gauge once a month and filling up before trips; it's safer and more worry-free.
As a car enthusiast, I enjoy delving into such details. An empty fuel gauge doesn't actually mean the tank is completely dry - most vehicles have a 1-3 liter reserve buffer to protect the fuel pump from burning out. How far you can drive depends on your fuel consumption rate: if your car averages 10 km per liter, 1 liter remaining gives you about 10 km. But actual distance may vary due to factors like rough terrain or AC usage increasing fuel consumption. I once tested this in a hybrid vehicle - driving smoothly in eco mode, it lasted over 40 km after the gauge hit empty. Important reminder: this reserve design is only for emergencies, not regular reliance, as repeated use can damage the fuel pump (which is notoriously difficult to replace). Pro tip: regular maintenance of your fuel system can extend its lifespan and prevent such predicaments.
