What are the effects after resetting fuel consumption?

Here is an introduction to the effects after resetting fuel consumption: 1. Introduction: After resetting the fuel consumption, the average fuel consumption displayed on the instrument panel will initially increase suddenly. The more kilometers driven after resetting and the larger the base, the smaller the change in displayed fuel consumption will be. With normal driving, the fuel consumption will gradually return to normal. The fuel consumption information displayed on the instrument panel is only for reference. Actual fuel consumption will vary accordingly due to factors such as driving habits, air conditioning usage, and changes in road conditions. For example, if the current route includes highways and smooth suburban roads, the average fuel consumption will be relatively low. If most of the driving is in purely urban areas, the average fuel consumption displayed will be correspondingly higher. 2. Effects: If the reset is performed while driving on the highway with constant throttle and speed, the subsequent fuel consumption will be much lower than before. If the reset is performed while the car is idling, the subsequent displayed fuel consumption will be relatively high, depending on the idling time—theoretically, it could be infinitely large, reaching the maximum value the car can display. If the reset is performed while the car is turned off, urban driving will result in much higher fuel consumption than before, while highway driving will show a decrease.
Resetting the fuel consumption essentially means clearing the average fuel consumption data stored in the trip computer. I used to do this often right after buying my car. After resetting, the fuel consumption figure displayed on the dashboard starts calculating from zero again, and the initial readings can be highly unstable—for example, driving in the city for half an hour might show 20L/100km, but a stretch of highway driving could bring it down to 6L. This has no real impact on the car itself, except that you lose the previous fuel consumption records, which is a bit of a shame. If you're testing fuel efficiency under different driving conditions, resetting can actually help observe the true performance more clearly. Just be careful not to reset it mid-way during a long trip, as you won't be able to see the average fuel consumption for the entire journey afterward.
I've noticed some people particularly enjoy resetting the fuel consumption gauge after refueling, which is quite an interesting habit. After resetting, the onboard computer starts collecting fresh fuel consumption data, so any aggressive driving within the next 20 minutes will immediately reflect on the dashboard – potentially giving you a scare. However, this practice doesn't affect engine performance or fuel level sensor operation at all; the actual fuel quantity in the tank remains unchanged. A friend once complained about inaccurate fuel consumption readings after resetting, but this is actually a misconception – the computer is simply recalculating. Over time, the records will gradually return to normal. I recommend regularly documenting your fuel consumption data to maintain reference points for comparison after resetting.
Honestly, there's a certain satisfaction in pressing that TRIP button to reset the fuel consumption data—it feels like starting a new accounting sheet. The most noticeable change after resetting is how the dashboard's fuel consumption display becomes hyper-sensitive to recent driving habits. If you reset it right after starting the car and immediately floor the accelerator, you might see an exaggerated reading like 30L per 100km in minutes, but that's just temporary calculation deviation. Critical components like the fuel pump and injectors remain completely unaffected, and the fuel level sensor doesn't reset either. However, losing historical data after resetting could be problematic if insurance companies require it, so it's wise to photograph important driving data as backup.
