How often is the carbon deposit removed

It will be different according to different models. Generally speaking, the 4s shop will recommend the car owner to maintain it every 10,000 kilometers. The car owner can extend it to 30,000 to 40,000 kilometers according to his own driving situation. Owners can clean up between 20,000 and 20,000 kilometers. Generally, the engine deposits are cleaned once every 20,000 kilometers. The following methods can reduce the formation of car carbon: 1. Use high-quality fuel. Because the main component of carbon deposits is formed by the wax and gum deposits in the fuel, the lower the gum content in the fuel, the better; 2. However, we cannot change the quality of the fuel, but we can choose to try not to add cheap fuels of unknown origin; 3. Avoid driving at low speed for a long period of time. If necessary, you can pull the high speed regularly. The principle of pulling high speed to eliminate carbon deposits is to accelerate the gas flow rate, which can take away a small part of the carbon deposits that are not yet firmly attached; increase the combustion temperature So that part of the carbon deposits in the cylinder are burned.
