How to Calculate Car Fuel Consumption?
2 Answers
Calculation method for car fuel consumption: The fuel consumption per 100 kilometers is equal to the volume of a certain amount of fuel (liters) divided by the distance the car can travel with that amount of fuel (kilometers) multiplied by 100. If a car consumes 4 liters of fuel and can travel 50 kilometers, then the car's fuel consumption per 100 kilometers is calculated to be 8 liters, commonly referred to as "8 liters of oil". Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning failure is a significant reason for high fuel consumption. Poor cooling performance of the air conditioner will increase the fan speed and lower the temperature to achieve a cooling effect. 2. Frequent sudden braking: Frequent sudden braking is the main cause of persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive use of air conditioning in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in the car. First, open the windows and set the fan to a higher setting without turning on the air conditioning to expel the hot air inside the car. Wait until the car has moderately cooled down before turning on the air conditioning.
When I used to drive a compact car, I always paid attention to fuel consumption, which essentially means monitoring how much distance is covered per unit of fuel. For example, I would fill up the tank and note the odometer reading, then drive a few hundred kilometers before refueling to full again, recording the amount of fuel added and the distance traveled. Fuel consumption is calculated by dividing the fuel added by the distance traveled and multiplying by 100 to get liters per 100 kilometers. My compact car typically consumed a little over 7 liters in the city and less than 6 liters on the highway. Several factors affect fuel consumption: driving habits are crucial—gentle acceleration saves more fuel than sudden bursts; road conditions also play a key role, with heavy traffic significantly increasing consumption; and vehicle condition shouldn’t be overlooked, as low tire pressure or poor engine maintenance can lead to higher fuel usage. By regularly recording and comparing data, I noticed that daily commuting consumes more fuel due to frequent stops at traffic lights, while long-distance driving is more economical. Accurately calculating fuel consumption helps estimate expenses and maintenance schedules in advance, avoiding breakdowns on the road.
