How Many Kilometers Before Refueling?

[RoseAnn]

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.

As a budget-conscious person, I always refuel when the remaining fuel level is at 1/4, typically visiting the gas station every 400+ kilometers. Waiting until the tank is nearly empty can damage the fuel pump, leading to costly repairs. Fuel consumption is a key factor—my compact car averages 10 liters per 100 km in the city, with a 45-liter tank, giving a range of around 450 km. To save fuel, I maintain smooth driving and avoid sudden braking, which helps extend intervals between refuels. I also regularly check tire pressure since low pressure increases friction and raises fuel consumption. In short, planning refueling mileage wisely not only saves money but also protects the car.

After years of driving, my experience is to refuel before the fuel gauge warning light comes on, approximately every 500 kilometers. With a fuel tank capacity of 50 liters and an average fuel consumption of 9 liters per 100 kilometers, the range is about 550 kilometers. For long trips, I set up gas station reminders in the navigation system to ensure refueling within every 500 kilometers, avoiding trouble in mountainous or remote areas. This frequency depends on the vehicle model—small fuel tank cars may need refueling every 300 kilometers, while large SUVs can go up to 800 kilometers. Also, pay attention to environmental factors; higher fuel consumption in winter can shorten the range. Don’t wait until the tank is completely empty, as it may cause vehicle malfunctions and affect safety.
