After the warning light comes on, the vehicle can still travel 20-30 kilometers without any issues. However, it is best to refuel as soon as the light turns on, as driving with low fuel can damage the fuel pump. Do not wait until the yellow light comes on to refuel: Before driving, check the fuel gauge and calculate whether you need to refuel based on the distance of your trip and the fuel level. It is advisable to refuel in advance rather than waiting for the fuel warning light to come on. The fuel pump is located inside the fuel tank and operates at high temperatures when continuously working. Being submerged in fuel helps cool it effectively. When the fuel light comes on, it indicates that the fuel level is below the pump. Repeatedly waiting for the light to come on before refueling will shorten the fuel pump's lifespan, and having too little fuel in the tank may even cause the pump to burn out. Refuel in the morning or evening: Timing your refueling can be quite strategic. Generally, temperatures are lower in the early morning and evening, and gasoline has a lower vaporization point. Therefore, it is better to refuel during these times. Gasoline expands with heat and contracts with cold, and it is sold by volume. At lower temperatures, gasoline has a relatively higher density, meaning the mass per unit volume increases, allowing you to get more fuel for the same price. Avoid filling the tank completely when driving in the city: City driving often involves frequent stops and starts. A full tank adds extra weight to the engine, increasing fuel consumption. Since gas stations are easily accessible in urban areas, there is no need to fill the tank completely.

I can usually drive about 40 to 60 kilometers after the fuel light comes on, but it really depends. As an experienced driver who's driven many cars, there's typically 5 to 10 liters of fuel left when the warning light illuminates. If you know your car's average fuel consumption—mine is about 8 liters per 100 kilometers—you can estimate around 50 kilometers. However, driving habits have a big impact: speeding, climbing hills, or using air conditioning will burn fuel faster, and city traffic jams can significantly reduce the range. The risks include breaking down on the road and potentially damaging the fuel pump, as running without fuel can overheat and damage components. For safety, head to a gas station as soon as the fuel light comes on—don't push your luck. It's wise to keep some emergency tools in your car or note down nearby gas stations for quick refueling when needed. This way, you can drive with peace of mind and avoid last-minute panic that could lead to accidents.

How far you can drive after the low fuel warning depends largely on your car's fuel consumption history. My habit is to prepare to refuel as soon as the light comes on. Most models can last 50 to 80 kilometers. For example, my SUV has a large fuel tank capacity, so when the light comes on, there's still plenty of fuel left, and it can go quite far if driven steadily on the highway. However, smaller cars may only have about 5 liters left, and in stop-and-go city traffic, they might only manage 30 kilometers. Speed is crucial: the most fuel-efficient range is between 60 to 80 kilometers per hour. Driving faster or with frequent speed changes consumes more fuel. It's advisable to note your average fuel consumption and calculate a conservative estimate with some margin. For instance, if you have 7 liters left and your consumption is 9 liters per 100 kilometers, plan for about 60 kilometers. Also, remember that the in-car display might have a delay, so don't rely on it completely. For long trips, plan your route in advance and start with a full tank for peace of mind.

Don't hesitate when the fuel light comes on, go refuel immediately. From experience, I can tell you it's generally safe within 50 km, but this varies by vehicle condition. Driving faster or uphill may reduce this range by a few kilometers, and city traffic congestion consumes fuel faster. Safety first - head to the gas station as soon as the light comes on to avoid potential breakdowns or accidents.
