How Often Should Carbon Deposit Cleaning Be Done?
2 Answers
It is recommended to clean the fuel injectors and intake tract every 20,000 kilometers, and to clean the engine carbon deposits every 2 years or when the vehicle reaches 40,000 kilometers. Additional Information: 1. Carbon deposits are typically formed due to sudden braking during driving or poor fuel quality. To minimize this, use higher-quality gasoline with better cleanliness, as lower-quality fuel can increase carbon buildup. 2. Untreated carbon deposits can lead to: clogging inside the engine, reduced power output, decreased engine efficiency, and increased fuel consumption.
Having driven for ten years, I feel the frequency of carbon deposit cleaning really depends on driving habits. For someone like me who commutes mostly in the city with frequent stop-and-go traffic, carbon deposits tend to build up quickly. Generally, I recommend cleaning every 20,000-30,000 kilometers, or having it checked during annual maintenance. If you often drive on highways or suburban roads with good conditions, carbon deposits accumulate slower, so you can stretch it to 35,000 kilometers. If neglected, engine power will weaken and fuel consumption will increase—I personally experienced much smoother performance after cleaning. Remember to choose reliable cleaning services; additives can handle most cases, but don’t overdo it—cleaning too often isn’t cost-effective. In short, tailor a personalized plan based on your vehicle’s manual and recommendations to ensure the engine runs healthily.
