Will Carbon Deposit Cleaning Affect the Engine?
2 Answers
Cleaning carbon deposits will not affect the engine. Cleaning cycle for carbon deposits in the cylinder: Generally, 4S shops recommend maintenance every 10,000 kilometers. However, drivers can adjust this based on their driving conditions. If you frequently drive on highways, the interval can be extended to 30,000-40,000 kilometers. For other drivers, cleaning can be done every 20,000-30,000 kilometers. Effects of excessive carbon deposits: Excessive carbon deposits can alter the engine's original structural parameters, reducing engine power and increasing fuel consumption. In severe cases, it may cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. Carbon deposits accumulate layer by layer, becoming thicker and leading to a vicious cycle. In extreme cases, they may block half of the intake valve, eventually resulting in engine oil burning and necessitating major repairs.
What's the impact of carbon deposit cleaning on the engine? I've been driving for over a decade and encountered this issue frequently. Carbon deposit cleaning primarily removes accumulated carbon residues in the engine, making it run more smoothly. After cleaning, it reduces engine vibrations, makes the car start faster, improves throttle response, and can even save some fuel costs in the long run. However, improper cleaning methods—such as using low-quality cleaners or DIY mishandling—can damage seals, cause oil leaks, or even lead to piston seizure. I recommend having it done by professionals rather than opting for cheap alternatives. During cleaning, it's also good to check the spark plugs; replace them if they're heavily carbon-fouled. Regular cleaning helps prolong engine life, especially for those who frequently drive on highways. Generally, cleaning every two years is appropriate—don't wait until carbon buildup becomes severe, as repairs will cost more then.
