How Often Should a Car Engine Be Cleaned?

[LandonMarie]

Car engines should be cleaned every 30,000 to 50,000 kilometers, and do not require too frequent cleaning. This is because most of the lubricants used in modern passenger cars come with self-cleaning functions, which can ensure that the engine does not produce sludge or only a minimal amount within a certain mileage. Generally, engine carbon cleaning is only necessary when the engine exhibits adverse reactions caused by carbon buildup, such as idle shaking. An engine is a machine that converts other forms of energy into mechanical energy, applicable both as a power-generating device and as the entire machine including the power unit. Types of engines include internal combustion engines, external combustion engines, electric motors, etc.
