How to Check Fuel Consumption?

[DiTanner]

You can check it through the fuel consumption display on the dashboard or calculate it yourself. Here is more extended information about car fuel consumption: 1. Definition: Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Indicator: The economic performance of a car is mainly represented by fuel consumption, which is an important performance aspect in vehicle usage. 3. Formula for calculating fuel consumption per 100 kilometers: Fuel consumption per 100 kilometers = Volume of fuel (liters) ÷ Distance the car can travel with that amount of fuel (kilometers) × 100.

I usually switch between the fuel consumption data displayed on the instrument cluster using the steering wheel buttons. Just scroll to the fuel consumption statistics page on the small central screen of the instrument panel, where both average fuel consumption and instantaneous fuel consumption are displayed. Instantaneous fuel consumption allows you to see the real-time fuel usage when pressing the accelerator, which is particularly helpful for adjusting driving habits. However, it's important to note that the fuel consumption calculated by the onboard computer may differ by about 1L from the actual consumption, so it's recommended to manually calculate it based on fuel refill amounts and mileage for greater accuracy. Additionally, a new car's fuel consumption will only stabilize after running about 3,000 kilometers, and higher readings during the cold start phase are normal. Regularly checking fuel consumption changes can also help detect vehicle issues in time, such as a sudden increase in fuel consumption possibly indicating low tire pressure or a need to replace the air filter.

The most accurate way to measure fuel consumption is to calculate it yourself. Each time you fill up the tank, reset the trip odometer. After running through a full tank, refill it again and record the liters of fuel added and the distance traveled. Divide the two to calculate the actual fuel consumption per 100 kilometers. After keeping records for three months, I found that using air conditioning in summer increases fuel consumption by about 0.8L compared to the displayed value. Although this simple method requires carrying a small notebook, it avoids the inaccuracies of the onboard computer. Once you develop the habit of recording, you can also compare the differences in fuel quality between different gas stations—the consumption difference between 92 and 95 octane gasoline can be as much as 5%. By the way, regularly clearing out unnecessary items from the trunk to reduce weight can also save fuel.

In my experience, operating the central control screen directly is the most convenient. Navigate to the vehicle information menu in the entertainment system settings, select the fuel consumption statistics, and you'll see the bar chart and historical curve. The new car's support for segment-specific recording is particularly useful—yesterday's highway data showed over 2L lower consumption than city driving. I noticed some models even allow customizing the display position in the instrument cluster theme settings. Remember to manually reset long-term fuel consumption records every three months to avoid data distortion. Actually, fuel consumption fluctuations are normal—for instance, my winter snow tire consumption is about 1.5L higher than in summer, and fuel grade differences can also have an impact.

I'm used to checking real-time fuel consumption data via mobile apps. After installing a CarPlay-compatible head unit in my car, the vehicle monitoring app on my phone can display instantaneous fuel consumption curves. The blue wave line jumps every time I brake, while the red curve spikes sharply during hard acceleration - this visual feedback really motivates me to break aggressive driving habits. Now it even has a fuel consumption alert function that vibrates the controller when exceeding preset thresholds. Actually, when monitoring daily fuel efficiency, pay attention to usage scenario differences: for example, rainy days with wet roads can increase consumption by about 10% compared to sunny conditions, and whether windows are open also makes noticeable differences.

I recommend checking by vehicle model. German cars often have a BC button at the end of the wiper stalk to toggle the display; Japanese and Korean models usually feature a small stick button on the right side of the instrument cluster; for domestic new energy vehicles, simply ask the voice assistant about fuel consumption. Note that for new cars, it's best to check the data after driving at least 300 km for reliable readings. The key factor affecting accuracy is the fuel tank float design—some vehicles may show inaccurate fuel levels when parked on an incline. A pro tip: For true fuel consumption figures, average the results over three full tanks of fuel. Also remember that cold starts in winter significantly increase consumption, and idling data beyond two minutes loses reference value.
