How to Determine if There is Carbon Buildup?

[LeCole]

Methods to determine if there is carbon buildup: If you experience slow acceleration, backfiring when accelerating suddenly, or difficulty starting the engine when cold, it usually indicates carbon buildup on the valves. Regularly cleaning the car's intake system can effectively reduce carbon formation. It is recommended that owners perform necessary cleaning on the intake system after driving approximately 30,000 kilometers. Severe carbon buildup can alter the engine's original structural parameters, reduce engine power, increase fuel consumption, and in serious cases, cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. In extreme cases, it may even lead to engine oil burning, requiring major repairs.
