How to Calculate Average Fuel Consumption?
2 Answers
Average fuel consumption is calculated by dividing the actual fuel consumption by the actual distance traveled, i.e., fuel consumption per 100 kilometers equals fuel consumption (liters) divided by distance traveled (kilometers) multiplied by 100. Average fuel consumption refers to the amount of fuel used by a vehicle per unit distance traveled, commonly expressed in liters per 100 kilometers. Fuel consumption per 100 kilometers refers to the average fuel consumption of a car traveling on the road per 100 kilometers. There is also instantaneous fuel consumption, which indicates the fuel consumption at a specific moment. This type of fuel consumption varies greatly, reaching over ten liters per 100 kilometers during acceleration and dropping to five or six liters per 100 kilometers during high-speed cruising.
I see many people want to know how to calculate average fuel consumption. The simplest method is to record the mileage and fuel amount when refueling. For example, if the odometer shows 2000 km after a full tank this time, and it displays 2400 km at the next refueling with 40 liters added. 40 liters were used for 400 km, divide 40 by 400 and multiply by 100 to get 10 L/100 km, which is the average fuel consumption for this period. When I calculate fuel consumption myself, I keep all gas station receipts and use a dedicated notebook to record data. Finally, I sum up the annual fuel volume and total mileage to calculate a more accurate comprehensive fuel consumption. The data calculated this way is much more accurate than the car's onboard computer, and it also shows the impact of using air conditioning in different seasons.
