How Often Should Carbon Deposits in a New Car's Engine Be Cleaned?

[McKingston]

Generally, it is recommended to clean the carbon deposits in the car's engine after 2 years of use or when the mileage reaches 40,000 kilometers. Introduction to Carbon Deposits: Carbon deposits refer to the black, sticky residues formed on components such as fuel injectors, throttle valves, fuel lines, spark plugs, cylinder heads, and inner walls due to incomplete combustion of gasoline in the cylinders. These residues are then subjected to repeated high temperatures in the engine. Hazards of Carbon Deposits to the Car Engine: If carbon deposits are not cleaned for a long time, it can lead to reduced engine power, increased fuel consumption, engine noise, and unstable idle speed.
