How Often Should Carbon Deposits in the Engine Be Cleaned?

[McAmir]

Here are more details on how often carbon deposits in the engine should be cleaned: 1. The most common method is to remove the throttle body, clean its front and back with carburetor cleaner, and wipe it dry with a cloth. It is generally recommended to clean the throttle body once a year or every 20,000 kilometers, though different models may have varying cleaning intervals, so refer to the maintenance manual. 2. Cleaning internal engine carbon deposits should be done before changing the engine oil. Open the oil cap, add a cleaning agent, mix it with the old oil, and let the engine idle for about 10 minutes. The cleaning agent can be purchased separately, and the process is very simple. 3. For intake system cleaning, purchase an intake system cleaner, pour it into the reservoir of a dedicated cleaning device, connect it to the intake system, and start the engine to allow the vacuum to draw the cleaner into the intake passages for cleaning. 4. Cleaning carbon deposits in the intake system mainly refers to removing deposits in the intake passages and intake manifolds. The goal is to eliminate internal carbon buildup, improve airflow and speed, and reduce engine vibration and idle instability.
