What is the formula for calculating fuel consumption per 100 kilometers?

The formula for calculating fuel consumption per 100 kilometers is the amount of fuel consumed divided by the distance traveled. The operation of a car relies on the combustion of gasoline, which inevitably contains some impurities. Over time, these impurities can accumulate on the engine surface, forming carbon deposits and sludge. This not only damages the engine but can also lead to difficulties in starting, high idle speeds, excessive exhaust emissions, and increased fuel consumption. The greatest resistance a car encounters while driving comes from air. If the car's body is covered with too much dirt and dust, it will increase the vehicle's resistance during movement. Never underestimate the impact of this seemingly minor layer of dust—it can significantly increase the car's fuel consumption due to the added resistance.
The formula for calculating fuel consumption is actually quite simple. I think the standard method is: Fuel consumption (liters/100 km) = (Fuel filled divided by distance traveled) multiplied by 100. Fuel filled is the amount of fuel you added, measured in liters; distance traveled is the number of kilometers driven. For example, last week I went on a long trip, filled up the tank, drove 500 km, and then refilled it with 40 liters of fuel. According to the formula: (40 liters / 500 km) * 100 = 8 liters/100 km. This way, you can monitor whether your car is fuel-efficient or not. Calculating it regularly can help you notice if the fuel consumption increases, which might indicate low tire pressure or the need for maintenance. I'm used to recording the mileage with a mobile app, entering the data after each refueling, and letting it calculate automatically. This can save a lot of money, especially with high fuel prices nowadays. Although the formula is basic, it's super practical and can help develop fuel-saving habits, reducing unnecessary expenses.
From a cost-saving perspective, the fuel consumption calculation formula is (fuel filled / kilometers driven) * 100, with the result being the fuel consumption per 100 kilometers. I often use it in my daily driving to monitor expenses. For example, last month I drove 300 kilometers and used 24 liters of fuel, calculating (24 / 300) * 100 = 8 liters/100km. If the fuel consumption drops from 8 liters to 7.5 liters, it can save hundreds of dollars a year, especially for SUV models. The advantage of the formula is its standardized approach, making it easy to compare the impact of different routes or weather conditions. I recommend keeping a small notebook to record fuel fills for quick and accurate calculations. It also serves as a reminder to avoid aggressive acceleration and reduce air conditioning use, directly lowering fuel costs, which can significantly help with the family budget in the long run.
