After how many kilometers should carbon deposits in a car be cleaned?
2 Answers
Carbon deposits should be cleaned after the car has traveled 20,000 kilometers. Here are some related extensions: Effects and solutions for excessive carbon deposits: If there is a significant buildup of carbon deposits in the engine over a short period, it can lead to higher fuel consumption, which is likely caused by using substandard fuel. The solution is to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a substantial buildup of carbon deposits in the engine, in which case the car should be taken to a 4S shop or repair shop for professional cleaning by a technician. Regular cleaning of carbon deposits is necessary: Pay attention to fuel quality and clean carbon deposits regularly. Poor-quality gasoline can increase carbon deposits, which in turn roughens the intake pipe walls, affecting air intake efficiency and mixture quality, leading to a sharp rise in fuel consumption. Therefore, fuel quality should not be overlooked, and cleaning carbon deposits every six months is essential.
Carbon deposit cleaning depends on driving habits and vehicle conditions. I usually get it done every 20,000 to 30,000 kilometers, but if you frequently encounter city traffic jams with long idle times, carbon builds up faster, so it's better to clean it every 15,000 to 20,000 kilometers. If you do a lot of short-distance driving, you should also be more diligent, as the engine doesn't fully warm up, leading to incomplete fuel combustion and easier carbon buildup. Last time I cleaned the throttle, the technician showed me the carbon deposits inside the cylinders with an endoscope—it was thick, like a layer of crispy rice crust. I recommend checking it during each maintenance session; don't wait until the car starts shaking to address it, as it might affect fuel efficiency and power. Regular cleaning keeps the engine breathing smoothly and makes throttle response sharper.
