Does a Car Engine Need Cleaning?

Engine cleaning is necessary as it effectively removes carbon deposits and debris. Engine Cleaning and Maintenance: Its primary function is to clean the sludge inside the engine and add an oil protectant to extend the lifespan of engine components. This maintenance project can be chosen based on your vehicle's condition if you have selected the oil type specified by the manufacturer and followed the manufacturer's mileage requirements for oil and filter changes. If the mileage is relatively low, you can decide whether to perform this maintenance each time based on your situation, which will provide some protection and cleaning for the engine. If the mileage is high or if you haven't performed regular maintenance before, you may skip it, as the effect won't be very noticeable. Benefits of Engine Cleaning: Cleaning Sludge from Oil Passages: The engine block is filled with oil passages, and over long-term use, sludge and other contaminants may accumulate inside these passages. Engine cleaning agents can help remove these sludge impurities from the oil passages, ensuring the proper functioning of the engine's lubrication system.
As someone who has been driving for nearly twenty years, I think engine cleaning is quite necessary. When carbon deposits build up over time, the engine will idle unevenly, lack power during acceleration, and fuel consumption will also increase. My old car is a perfect example—there was a period when it struggled to climb hills, but after getting the carbon deposits professionally cleaned, it ran much smoother. The cleaning method is quite simple: the mechanic adds a cleaning agent to the fuel system, and after driving a few laps, the dirt dissolves. It costs around two to three hundred yuan, which is cost-effective. In terms of frequency, for someone like me who often gets stuck in city traffic, I recommend cleaning every two to three years; for those who drive long distances on highways more often, it can be extended to four or five years. Don’t forget regular maintenance—changing the oil more frequently can also prevent carbon buildup. For safety, don’t try to do it yourself; it’s best to go to a professional shop.
