Engine cleaning sludge: solve the sludge problem and HS code reference for mineral exportsclean it easily! With the increasing use time of cars, the problem of oil sludge is becoming more and more common. Oil sludge mainly refers to the carbon accumulation, sediment and other impurities generated inside the engine. These substances will be attached to various parts of the engine. If it is serious, it will hinder the normal operation of the engine and even cause damage to the engine. Routine measures such as replacing the oil filter and adding oil cleaner cannot completely solve the problem. Therefore, many car owners can solve this problem by cleaning the engine sludge in daily maintenance, which can not only extend the life of the engine, but also improve the performance and safety of the car. I. Why does the engine need to clean the oil sludge?The long-term use of cars will produce oil pollution and impurities, forming carbon accumulation and causing oil sludge problems that cannot be ignored. This problem will gradually penetrate into the entire engine and block the normal operation of certain parts, which will lead to poor performance of the engine. If it is not cleaned in time, it may cause the following problems: 1. The engine noise increases 2. The oil is cloudy and the color turns black 3. Slow acceleration of the engine 4. Oil filter element contamination 5. Engine stuck II. When does the engine need to be cleaned? 1. Often driving in congested urban traffic, vehicles that are often used at low speed, idling or parking for a long time. Two. Low-quality oil has been used for a long time, and the oil has not been replaced according to the regulations. 3.
