What is the formula for calculating actual fuel consumption?
2 Answers
Calculate the fuel consumption per 100 kilometers using the formula: Fuel consumption per 100 km = Volume of fuel consumed (liters) ÷ Distance traveled (kilometers) × 100. Here are specific methods to reduce fuel consumption: 1. Lightly press the accelerator: The initial low-speed acceleration phase is the peak fuel consumption period, so gently pressing the accelerator to prevent excessively high RPM can effectively reduce fuel consumption. 2. Avoid high RPM: Try to avoid unnecessary high RPM, as fluctuating engine speeds can significantly increase fuel usage. 3. Regular maintenance: Change the engine oil and remove carbon deposits. 4. Avoid emergency braking: Anticipating road conditions not only enhances driving safety but also saves fuel, such as gradually slowing down before traffic lights and utilizing inertia to coast.
I often drive to and from work, so calculating actual fuel consumption is quite important for budgeting. The formula is to divide the liters of fuel refilled by the kilometers driven and then multiply by one hundred, which gives the fuel consumption per 100 kilometers. For example, last month I refueled three times, each time filling the tank to full and recording the mileage. The total fuel refilled was 120 liters, and the total distance driven was 1,500 kilometers. (120/1500)*100 = 8 liters per 100 kilometers. Remember to always record the starting mileage and fuel amount after each full refuel—this ensures the most accurate calculation. Some people forget this or don’t fill the tank completely, leading to significant deviations in the results. I recommend using a mobile app like Xiaoxiong Youhao (Little Bear Fuel Consumption) to automatically track consumption and reduce manual hassle. Regular calculations can help identify the car’s health: if fuel consumption suddenly rises, it might indicate low tire pressure or engine carbon buildup. To save money, I calculate the average every 1,000 kilometers to ensure it stays within budget. In practice, avoid measuring fuel consumption during short trips with cold starts, as this tends to skew higher; instead, calculate during long-distance drives for a more accurate reflection of real-world conditions.
