Does the car need to clean up the carbon deposit in the combustion chamber for 60 thousand kilometers?

The carbon deposit in the combustion chamber is the engine's own. In addition to the combustion chamber, there are also carbon deposition problems in the fuel injector, valve back and air intake. Carbon deposition refers to the carbide formed by the combination of black ash and colloid produced by insufficient combustion of the engine at idle speed and low speed. If it is an engine, it will accumulate carbon more or less. There are two ways to clean up carbon deposits: cleaning with fuel additives and cleaning with cleaning agents. Finally, it is decomposed clean. Whether the 60,000 km engine cleans the combustion chamber depends on the situation. Depending on whether you are used to developing motivation, the amount of carbon deposition will be different. Frequent high-speed driving will reduce carbon deposition, and frequent driving in urban areas will slightly increase carbon deposition. Personally, I suggest using fuel additives regularly. Fuel additives can effectively soften carbon deposits, and it is safe, convenient and efficient without disassembling engine parts. General manufacturers require the use of fuel additives every 5000- 10000 kg. It is best to choose big brands, such as Chevron, Red Line, Limo, BASF, Happy Run G 17, Mobil G 17 and Carbon Boss.
