How to calculate fuel consumption with AVG on a car?

First, fill up the car with fuel, then reset the odometer to zero before driving. The purpose of resetting the odometer is to facilitate fuel consumption calculation. When the car has traveled 100 kilometers, stop to obtain the fuel consumption for that distance. Fuel consumption per 100 kilometers = Amount of fuel consumed ÷ Distance traveled × 100.

Calculating average fuel consumption in a car is actually a straightforward process. From my years of driving experience, the AVG function in vehicles is computed by the built-in computer using sensors to record real-time mileage and fuel consumption for averaging. Each time you refuel, the system logs the change in fuel level; while driving, it automatically calculates fuel consumption per 100 kilometers by combining odometer data—for example, if you drive 200 kilometers using 16 liters of fuel, the AVG will display 8L/100km. This calculation helps monitor driving habits. I often check it after long trips to remind myself to maintain tire pressure and avoid sudden acceleration for better fuel efficiency. Although the data may vary due to road conditions or air conditioning usage, pressing the reset button periodically ensures accuracy by resetting the average. Overall, understanding it facilitates optimizing fuel efficiency.

The AVG fuel consumption in the car is intelligently processed by the electronic system. As someone familiar with vehicle technology, I can explain it: the computer collects real-time data from the fuel level sensor and odometer; while you're driving, it continuously updates, dividing the consumed fuel by the distance traveled and multiplying by 100 to calculate the liters per 100 kilometers. For example, if you burn 5 liters of fuel over 50 kilometers, the AVG will display 10. This reading is heavily influenced by sensor accuracy, and higher values in congested urban areas are normal. It's recommended to manually reset the calculation for more reliable results. The system automatically calibrates after refueling, helping you monitor fuel efficiency and reduce waste. Understanding this principle can make your driving more efficient and save you unnecessary expenses.

When I first learned to drive, I was always curious about how AVG (average fuel consumption) is calculated. Simply put, the car's computer automatically calculates fuel consumption: it tracks how far you've driven after refueling. For example, if you drive 50 km on a full tank and the fuel gauge drops by one bar, it divides the consumption by 50 to display the average value. Most cars have settings on the dashboard where you can press a button to reset it and start calculating a new average. This makes it convenient for you to compare the impact of different driving habits.
