1 10,000 km maintenance, do you need to clean the engine carbon deposit?

It depends on the specific situation. Due to the different quality of oil products in different places in China, there will be more carbon deposits in places with poor oil quality. It also depends on whether there are frequent traffic jams at this time of driving. For example, in places like Beijing and Shanghai, the speed is 10000 kilometers per hour. Because the speed cannot be improved for a long time, there will be more carbon deposits in some places with good road conditions than cars. If so, it is necessary for you to do it.
