How often do you clean up the carbon deposits in new cars?

Under normal circumstances, the carbon deposit must be removed once when a new car travels 20,000-30,000 kilometers. If you often run at high speed, it can be increased to 30 thousand to 40 thousand kilometers. According to different cars and different driving habits, the cleaning cycle of carbon deposits is different. People can also choose cars according to their driving conditions.

Olefin and gum in engine oil and fuel will produce black combustion products and accumulate in the engine system if they are not fully burned at high temperature. Moreover, carbon deposition will absorb oil and fuel combustion will not be sufficient, so carbon deposition will increase.

It is impossible to remove carbon deposits by pulling the throttle at high speed in neutral, because the engine will not produce actual power and the air intake will not increase when the car is not running, so this method is not desirable at all. In addition, the adhesion of carbon deposit is very strong. Once it is formed in the intake and exhaust system, it is very powerful. There is no way to remove it in the ordinary way. The only way is to clean it in 4S stores. Million car purchase subsidy
