Does a Car Need Carbon Deposit Cleaning? Cars require regular carbon deposit cleaning. Here are the relevant details: Regular Cleaning: It depends on the situation. For cars driven in urban areas, cleaning is recommended every 20,000-30,000 kilometers, while for those driven on highways, every 30,000-40,000 kilometers. According to the Maintenance Manual: Owners can refer to their vehicle's maintenance manual and the recommended spark plug replacement interval to check for carbon deposits and perform necessary cleaning. Generally, maintenance manuals suggest replacing spark plugs every 20,000-30,000 kilometers, making it appropriate to clean the engine's carbon deposits during this interval. Specialized Equipment Cleaning: This involves using specialized equipment to clean carbon deposits from areas prone to buildup, such as the intake tract, valves, and fuel system, without disassembling the engine.
