How Often Should Carbon Deposits Be Cleaned in a New Car?
1 Answers
Generally, a new car requires carbon deposit cleaning every 20,000 to 30,000 kilometers. If the car is frequently driven on highways, this interval can be extended to 30,000 to 50,000 kilometers. Car owners can decide based on their driving conditions. If the carbon deposits in the engine are not severe, there is no need for specialized cleaning. However, if the carbon deposits are significant, it is advisable to clean them every 30,000 to 50,000 kilometers. Areas prone to carbon deposits include the engine combustion chamber, intake ports, valves, and throttle body. Carbon deposits have a considerable impact on the engine. If they accumulate in the combustion chamber, they can increase the compression ratio, leading to engine knocking. Knocking is an abnormal combustion condition that affects engine power output and fuel efficiency. It typically occurs during the compression stroke when both the intake and exhaust valves are closed, and the piston moves upward. Methods for cleaning carbon deposits include using gasoline additives, specialized cleaning agents, or disassembling the engine. Using gasoline additives, commonly known as fuel system cleaners, is the most feasible and practical method. Disassembling the engine is usually reserved for cars that have traveled 200,000 to 300,000 kilometers with little or no carbon deposit cleaning and noticeable engine performance degradation. For a new car, it is recommended to use a full course of fuel system cleaner around 20,000 kilometers. A full course typically consists of about 300ml of cleaner. Some products come in five 60ml bottles, while others are in a single container, with 1/5 added each time the tank is filled. Completing a full course requires about five refuels, covering approximately 3,000 kilometers. Since carbon deposits are not severe at this stage, the effects may not be immediately noticeable.
