What does Average Fuel Consumption 1 and 2 mean?

[DelArthur]

Fuel Consumption 1 refers to the average fuel consumption of the current trip, which resets after 2 hours. Fuel Consumption 2 refers to the average fuel consumption within 100 hours of driving, and it resets after accumulating 100 hours of driving. Here are some methods to reduce fuel consumption. Summer Air Conditioning System Check: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance can lead to increased fan speed and lower temperature settings to achieve a cooling effect. Frequent Hard Braking: Frequent hard braking is a primary reason for persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. Avoid Overusing Air Conditioning in Small-Displacement Cars: For vehicles exposed to the sun, it's not advisable to turn on the air conditioning immediately upon entering. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. Wait for the car to cool down moderately before turning on the air conditioning.

Last month I just bought a new car, and it displays Average Fuel Consumption 1 and 2. At first, I was confused. After driving for a while, I realized that Average Fuel Consumption 1 is actually short-term fuel consumption, recording data from my recent one or two drives. If stuck in peak-hour traffic, that number can skyrocket to over 10L/100km. Average Fuel Consumption 2, on the other hand, is long-term fuel consumption, calculating the overall average over several months, which is more stable—mine stays around 7.5L/100km. After understanding this, I started paying attention to my driving habits, like avoiding sudden braking and acceleration, and using cruise control more often on highways. Gradually, my long-term fuel consumption (Average 2) decreased, saving me some fuel costs. These displays are especially useful for beginners, helping me optimize my driving. If the fuel consumption rises, it reminds me to check the car's condition or ease off the accelerator.

After driving for ten years, I've got a clear understanding of the purposes of Average Fuel Consumption 1 and 2. Average Fuel Consumption 1 tracks short-term driving conditions, such as right after starting the car or performance over the last half hour; Average Fuel Consumption 2 represents long-term trends, possibly accumulating data over several weeks since the last reset. For me, they don't just show fuel efficiency but also provide insights into my habits—sharp turns or sudden acceleration can spike Consumption 1, but if the long-term Consumption 2 remains low, it indicates overall smooth driving. I often adjust my driving style based on these readings, like avoiding rush hours and maintaining steady speeds, which saves money and enhances safety. I recommend beginners check these regularly—if consumption exceeds 10, it might indicate a tire leak or excessive AC use, and timely maintenance can prevent bigger issues.

As a working professional who commutes by car every day, Average Fuel Consumption 1 and 2 help me accurately calculate my monthly fuel budget. Average Fuel Consumption 1 is short-term data—it shows lower readings right after highway driving but spikes when stuck in traffic, with significant fluctuations. Average Fuel Consumption 2, on the other hand, is a stable long-term average that better reflects actual expenses. I check it weekly, and if it exceeds 9, it reminds me to change the engine oil or check tire pressure. Resetting it is simple—just press the dashboard button or select it in the menu, no need for frequent adjustments. Such small tools make driving more economical and help cultivate good habits, like reducing speeding and closing windows to save fuel.

From an environmental perspective, Average Fuel Consumption 1 and 2 are crucial. My beloved car shows that Consumption 1 reflects real-time or short-term data – higher values indicate more emission pollution; Consumption 2 covers long-term driving patterns, and lower values demonstrate I'm reducing my carbon footprint. I use these metrics to monitor driving impact – for instance, gentle acceleration or maintaining steady highway speeds can keep long-term consumption around 6L/100km, saving money while being eco-friendly. I recommend frequent use of cruise control and regular engine maintenance. These displays truly serve as helpful tools for green living.

I enjoy tinkering with the car's onboard computer. The average fuel consumption 1 and 2 are displayed on the dashboard. Fuel consumption 1 is for short-term calculation and can be reset at any time to monitor new trips, while fuel consumption 2 is for long-term recording of overall efficiency, which I never reset to track the vehicle's overall condition. Adjusting driving habits, such as sudden acceleration, can temporarily increase fuel consumption 1, but maintaining the vehicle, like cleaning the air filter, can improve the long-term performance of fuel consumption 2. This tool is incredibly useful for DIYers and can also be connected to an OBD diagnostic tool to check fault codes, ensuring the engine remains healthy and fuel-efficient.
