How Many Kilometers Before Refueling?
2 Answers
Generally, refuel when the remaining driving distance is about 100 kilometers. Precautions: Do not wait until the fuel is completely used up before refueling. For fuel-injected vehicles, the electric fuel pump is cooled by the fuel in the tank. Running out of fuel may cause the vehicle to break down midway or even damage the engine. It may also burn out the fuel pump. Additionally, there are more impurities at the bottom of the tank, which can clog the fuel system. Other Considerations: If you are not traveling long distances, filling the tank to two-thirds capacity in urban areas is sufficient. Overfilling increases the vehicle's weight, which in turn increases fuel consumption. Refueling within the specified safe capacity is acceptable. Safe Capacity: The officially marked fuel tank capacity is the safe capacity. Considering vehicle safety and the thermal expansion and contraction characteristics of fuel, manufacturers design the fuel tank with a certain safety margin.
I drive a regular family sedan, and after each refueling, it can run about 500 to 600 kilometers. This mainly depends on the car's fuel tank capacity and my driving habits. My fuel tank is around 50 liters, and the fuel consumption during daily city commuting is about 8 liters per 100 kilometers, while on the highway, it can drop to 6 liters, so the range is longer on highways. However, I usually refuel when the fuel gauge shows about 100 kilometers remaining to avoid running out of gas midway and causing delays. This is highly related to road conditions—fuel consumption spikes in traffic jams, reducing the range. I suggest beginners calculate based on their car's specifications: divide the fuel tank capacity by the fuel consumption to estimate the approximate range. Developing a good habit of timely refueling is important to avoid affecting daily travel.
