Is Engine Carbon Deposit Cleaning Necessary?
2 Answers
Engine carbon deposit cleaning is necessary. Below are specific details about engine carbon deposit cleaning: Benefits of carbon deposit cleaning: Improves vehicle power; saves fuel consumption; reduces knocking points; promotes environmental maintenance; extends engine lifespan; enhances braking accuracy. Cleaning methods: Remove the throttle body, clean both sides with carburetor cleaner, and dry with a cloth. Generally, clean the throttle body once a year or every 20,000 kilometers; for internal engine carbon deposit cleaning, it can be done before changing to new engine oil. Open the oil cap, add a cleaning agent, mix it with the old oil, and let it idle for about 10 minutes; for intake system cleaning, buy a bottle of intake system cleaner, pour it into the storage tank of a specialized cleaning device, connect it to the intake system, and use vacuum to draw the cleaner into the intake passages for cleaning. Cleaning intake system carbon deposits mainly refers to cleaning the carbon deposits inside the intake passages, intake manifolds, etc. This removes internal carbon deposits in the intake system, increases intake flow and speed, and reduces engine shaking and idle instability.
I've been driving for over a decade and have deep personal experience with engine carbon buildup. Recently while waiting at a red light, I clearly felt severe steering wheel vibration, sluggish acceleration when stepping on the gas pedal, and significantly higher fuel consumption than before. After inspection at the repair shop, the mechanic said the spark plugs were completely fouled by cylinder carbon deposits. After cleaning, it felt like driving a brand new car - the acceleration became powerful again and idle vibration disappeared. Since I mostly drive in city traffic with frequent stops, short-distance trips cause the most carbon buildup. The mechanic recommended checking every 40,000-50,000 km. Don't wait until engine knocking or cylinder scoring occurs - those repairs will really make your wallet cry.
