How is car fuel consumption calculated?

[McGia]

The correct formula for calculating fuel consumption: Fuel consumed ÷ Distance traveled × 100 = Fuel consumption per 100 kilometers. The data on fuel consumed is relatively difficult to obtain, so the usual method is to start with a full tank as the initial data, drive a certain distance, and then refill the tank to full, using the fuel quantity provided by the gas station as the accurate measurement. Specific steps: 1. First, fill up the vehicle's tank, then reset the odometer to zero before driving. 2. After driving 200 kilometers, go to a gas station to refuel, and the fuel dispenser shows 15 liters after filling up. 3. According to the formula (15 ÷ 200 × 100 = 7.5), the vehicle's fuel consumption per 100 kilometers is 7.5L. Note: 1. Personal driving habits, road conditions, vehicle load, tire pressure, and weather can all affect fuel consumption, leading to variations. 2. A more scientific method for calculating fuel consumption involves averaging the data. Drive the vehicle for 10,000 kilometers, record the data from multiple refueling sessions during this period, and then take the average of the highest and lowest fuel consumption values. This approach yields relatively more scientific data.
