How many kilometers can one liter of oil run?
2 Answers
One liter of oil can typically drive a small car about 10 to 15 kilometers in the city. On the highway, if driving at a constant speed, one liter of oil can cover approximately 20 to 30 kilometers. Fuel consumption is determined by the car's engine displacement and each driver's driving skills. It's important to refuel in a timely manner and not to fill the tank completely. It is not recommended to wait until the fuel light comes on to refuel, as this can damage the fuel pump. Also, try not to fill the tank to the brim, as a full tank of fuel is equivalent to the weight of an adult. If you're not traveling long distances and mainly driving in the city, there's really no need to fill up completely. Additionally, avoid refueling during the hottest part of the afternoon. It's better to refuel when the temperature difference between day and night is significant. Refueling 50 liters at noon compared to early morning is equivalent to getting half a liter less fuel, as fuel dispensers measure by volume, not by mass.
I drive an economy car, and it typically runs 14 to 16 kilometers per liter of fuel, depending on how I drive. In the city with heavy traffic and frequent stops at traffic lights, sudden braking and acceleration can drop the efficiency to around 12 kilometers per liter. But on the highway, driving steadily with the air conditioning on, it can sometimes reach 18 kilometers per liter. The vehicle's condition has a significant impact—for example, if the engine oil viscosity is too high or the air filter is clogged, fuel efficiency can drop noticeably. I make it a habit to check tire pressure monthly, keeping it at the recommended level to reduce rolling resistance. In winter, after warming up the engine during cold starts, fuel efficiency improves, while in summer, using the air conditioning consumes more fuel. With fuel prices high now, I try to avoid peak travel times and have developed the habit of checking navigation in advance to avoid detours. These experiences have taught me that driving habits account for half the factors, and the size of the vehicle is also crucial—SUVs generally have higher fuel consumption. To get precise data for your own car, you can fill up the tank, record the mileage, drive a few hundred kilometers, then refill and calculate the average.
