How Often Should Engine Carbon Deposits Be Cleaned?

[MacIan]

Engine carbon deposit cleaning practices may vary among different 4S shops, which are as follows: 1. Generally, 4S shops recommend car owners to perform maintenance every 10,000 kilometers. 2. Car owners can also decide based on their driving conditions. If driving on highways for extended periods, the interval can be extended to 30,000-40,000 kilometers, while other car owners can opt for cleaning at 20,000-30,000 kilometers. Additional information: It is advisable to regularly use legitimate fuel additives with cleaning effects. Their working principle is: They possess strong surface activity, enabling them to penetrate the pores of carbon deposits, disrupt their structure, and encircle these carbon particles, gradually dissolving them from the metal surface. These particles are then expelled through the exhaust after high-temperature combustion with the fuel.
