Will Fuel Consumption Decrease After the First Maintenance of a New Car?

[VanClayton]

After the first maintenance of a new car, fuel consumption will decrease. Once the initial engine oil is replaced, many impurities and metal shavings are removed, improving lubrication, which certainly contributes to reducing fuel consumption. Engine oil plays a crucial role in lubricating the engine. The first maintenance is typically performed at 3 months or 5,000 kilometers. During the initial run-in period of the engine, impurities and metal shavings are generated, which are then drained and replaced along with the oil. In fact, personal driving habits also significantly affect fuel consumption. Most new car owners are beginners who are just starting to drive. They may not yet be proficient in controlling the throttle depth, coordinating the clutch and accelerator, or determining the right time to shift gears. For example, frequently driving at high RPMs in low gears can lead to higher fuel consumption during the break-in period.
