What is the formula for calculating car fuel consumption?

[VanHope]

Fuel consumption per 100 kilometers = Volume of certain fuel amount ÷ Distance the car can travel with that fuel amount. Below is an introduction to fuel consumption and the formula: 1. Principle: If a car consumes A liters of fuel while traveling N kilometers, then the fuel consumption per 100 kilometers = A ÷ N × 100. Substituting specific numbers, if a car consumes 4 liters of fuel to travel 50 kilometers, then the car's fuel consumption per 100 kilometers = 4 liters ÷ 50 kilometers × 100 = 8 liters/100 kilometers. The fuel consumption per 100 kilometers is 8 liters. 2. Fuel consumption: Commonly known as the amount of fuel a car consumes after traveling 100 kilometers. The economic indicator of a car is mainly represented by fuel consumption, which is an important performance characteristic in car usage. Especially in China, where fuel tax is to be implemented, the fuel consumption parameter of cars holds particular significance.

Calculating fuel consumption, I have an old-school method: Wait until the fuel gauge is near zero before filling up the tank, then record the liters of fuel added and the kilometers driven since the last fill-up. The formula is simple: (Liters of fuel ÷ Kilometers driven) × 100, which gives you the fuel consumption per 100 kilometers. For example, last week I filled up 40 liters after driving 500 kilometers, which works out to 8 liters per 100 kilometers. I've been using this method for over a decade, and it's very accurate. The key detail is to wait until the tank is nearly empty before refueling to avoid miscalculations from partial fill-ups. Also, always write it down instead of relying on memory to prevent mileage errors. When fuel consumption seems high, check tire pressure or the air filter—it might be a minor issue. Driving slower and avoiding aggressive acceleration can save 1-2 liters per 100 kilometers.

I usually drive to work and always calculate fuel consumption to save money. The formula is (liters of fuel filled divided by kilometers driven) multiplied by 100. Here's a real example: last time I filled 30 liters and drove 450 km, the calculation came out to 6.67 L/100km. I like recording these numbers in my phone calendar for easy reference. Fuel consumption is higher for short city trips but drops significantly on long highway drives. It's especially noticeable when the AC is on full blast, so I use fans more than AC in summer. Calculating fuel consumption helped me spot a car issue – last time it suddenly rose to 9L/100km, and inspection revealed a faulty oxygen sensor. This habit is quite easy to develop.

I find the fuel consumption formula quite practical: (liters of fuel added divided by kilometers driven) × 100. Last time I added 50 liters and drove 800 km, which comes to 6.25 liters per 100 km. I prefer eco-driving, maintaining a steady speed of 60-80 km/h is the most fuel-efficient. Calculating helps me know if my driving habits have improved, and minimizing braking and acceleration is the most effective.

I just learned the fuel consumption formula: (Fuel filled divided by kilometers driven) multiplied by 100. Last week, I filled up 35 liters and drove 500 kilometers, resulting in 7 liters per 100 kilometers. Newcomers will get the hang of it after a few tries, and the data from the car's onboard computer generally matches. Remember to fill up the tank and reset the odometer when setting off for higher accuracy.
