Will the engine noise decrease after the break-in period for a new car?

[LaTheo]

After the break-in period, the engine noise of a new car will decrease slightly because the car's components will reach their optimal combined state. Avoid prolonged high-speed driving during the break-in period: During the break-in period of a new car, avoid prolonged high-speed driving. High-speed driving causes the engine to operate at high RPMs, which can easily lead to engine overheating and exacerbate abnormal wear. Excessive engine noise during the break-in period: Since the engine is not fully broken in during this period, there may be some noise. If the noise is particularly loud, it is recommended to visit a 4S shop for inspection to ensure the car operates normally during the break-in period. Abnormal engine operation during this period can lead to excessive wear, thereby reducing the engine's lifespan.
