Will the fuel consumption of Corolla decrease after the first insurance?

Will the fuel consumption be reduced after the first insurance? Indeed, the average fuel consumption before the first insurance was 6.3, and the fuel consumption was reset after the first insurance, and the fuel consumption was 6.4. Now the car is still talking about running-in, and the new car runs at high speed 100 yards. No, it says it will drop after maintenance. The car has been bought and driven for hundreds of kilometers, and the average fuel consumption is stable. There is no difference. It doesn't matter, there is no so-called "running-in fuel consumption" ... this was twenty or thirty years ago. What does the new car look like, and what will it look like later, unless the road conditions and driving level have changed greatly ... It is basically irrelevant to see whether the personal driving habits are guaranteed for the first time and whether the fuel consumption is not directly related. Any theory of reducing fuel consumption after the first insurance is nonsense. After the vehicle engine is replaced with new oil, the lubricity and heat dissipation will be better, so the fuel consumption will decrease slightly. Fuel consumption depends on vehicle weight, road congestion, driving habits of vehicle owners, etc. Many factors will affect fuel consumption, so everyone will be different. There are many factors that affect fuel consumption: one-way driving distance, season (slow water temperature in winter), driving habits, average speed and so on. If these factors are not good, fuel consumption will inevitably be high, and vice versa. Look at the average speed and kilometers per trip. Generally, short-distance driving consumes more fuel. Everyone's car environment is different, and various factors are superimposed together, and the fuel consumption is also very different. Fuel consumption may not be reduced after the first insurance. @20 19
