Does a new car need carbon deposit cleaning at 20,000 kilometers?

A new car does not require carbon deposit cleaning at 20,000 kilometers. Under normal circumstances, it generally needs to be cleaned every 30,000 to 50,000 kilometers, and cleaning should not be too frequent. The reasons are as follows: Cleaning agents are corrosive and can corrode metal parts inside the engine, leading to engine malfunctions. If the mileage is relatively long, cleaning the engine can reduce engine oil pressure and cause issues like cylinder gasket leaks, resulting in significant damage. Precautions for car carbon deposit cleaning: The concentration of the cleaning agent must be adjusted. Different levels of oil contamination require different concentrations. Additionally, after cleaning, it is essential to promptly remove any residue to prevent residual liquid from corroding the engine. When using cleaning agents, read the instructions carefully and follow the guidance of professionals. Cleaning methods can include ultrasonic cleaning, spraying, hot soaking, and manual wiping. To achieve effective cleaning, the environment is crucial. It is best to clean under temperature conditions of 55 to 80 degrees Celsius.
