How Often Should Carbon Deposits Be Removed from the Engine?

[SanJackson]

4S shops usually recommend car owners to perform maintenance every 10,000 kilometers. However, owners can adjust this interval based on their driving conditions. If the car is frequently driven on highways, the cleaning interval can be extended to 30,000-40,000 kilometers. For other drivers, cleaning every 20,000-30,000 kilometers is sufficient. Below are methods for cleaning carbon deposits from the engine: 1. Engine Carbon Cleaning via Drip Bottle: A bottle-shaped tool is suspended above the engine, filled with cleaning agent, which is then introduced into the engine through a tube to remove carbon deposits. However, if the engine has severe carbon buildup, this method may clog or damage the catalytic converter. 2. Machine Cleaning: The cleaning agent is injected into a machine, pressurized, and sprayed into the combustion chamber, where it reacts with and dissolves the carbon deposits. The waste liquid is then extracted. This method is highly effective for severe carbon buildup and does not require engine disassembly, but it is more expensive, and the engine oil must be replaced afterward.
