How many kilometers can a car run when it reaches the red line?

When the fuel gauge needle of a car reaches the red line, there is approximately 10% of fuel left in the tank, and on average, the car can continue to run for 20km to 60km, but this depends on the specific model. Here is some additional information: 1. Distance limit: When the fuel gauge indicator light comes on and reaches the red zone, there is usually 15% to 20% of the total fuel capacity remaining. The distance you can drive depends on calculations. For example, if you are driving on a highway and the fuel gauge light comes on, there is no need to worry, as the distance between highway service areas is generally around 40km and should not exceed 60km. 2. Fuel-saving methods: Control your speed and drive smoothly. According to tests, for low-displacement cars (1.3-1.8L), the most fuel-efficient speed is between 45-65km/h, while for cars with 2.0-3.0L engines, the most fuel-efficient speed is between 55-75km/h. Turn off all electrical appliances in the car. Navigation, radio, music, air conditioning, etc., and closing the windows to reduce wind resistance can also help save fuel.
I've been driving for many years, and it's really hard to say how far you can go when the fuel gauge hits the red line, because it depends on your car model, driving habits, and road conditions. With the compact car I drive, last time I managed to go about 40 kilometers after hitting the red line, especially in city traffic with frequent stops and starts, which is more fuel-efficient. But I had to rush to refuel when the fuel light came on. Some larger cars or SUVs might easily go over 50 kilometers on the highway. However, I must remind you not to always risk driving to the red line. Too little fuel can cause the fuel pump to overheat or even get damaged, and long-term damage can cost a lot in repairs. It's best to develop the habit of refueling when the tank is half empty to avoid breaking down unexpectedly on the road. In short, safety first, and timely refueling is the key.
From a technical perspective, when the fuel gauge needle points to the red line, the remaining fuel in the tank is typically around 1 to 2 liters, which is enough to drive 30 to 80 kilometers depending on vehicle weight, speed, and environment. If driving at a constant speed on the highway with lower wind resistance, you might reach closer to the upper limit; in congested urban areas, fuel consumption is faster, possibly leaving only 20-plus kilometers. I recommend paying attention to the dashboard while driving—once approaching the red line, slow down and maintain steady throttle to save fuel, and plan a refueling stop as soon as possible. Don’t wait until the warning light comes on to act; if the fuel pump burns out, the repair cost could be much higher than refueling a bit earlier. Regularly check your vehicle manual, which will indicate the actual remaining distance reference value.
Last time my friend drove his old car to the red line, insisting it could go 60-70 kilometers, but it broke down after just 20 km, forcing us to call a tow truck. I think it largely depends on luck: new or hybrid cars are designed with some margin, possibly allowing them to go farther; but older cars have more wear in the fuel system, and the fuel pump is prone to failure, causing issues if you're not careful. In short, the red line is no joke—it's best to find a gas station immediately. When I was learning to drive, my instructor told me to develop the habit of refueling when the gauge hits half to avoid stress and delays. If you accidentally reach this state, stay calm, avoid sudden acceleration, roll down the windows to save on AC fuel, and pull over as soon as possible. Prompt action is great for your car's health!
