Can Frequent Oil Changes Remove Sludge?
1 Answers
Frequent oil changes can remove sludge. The stronger the circulating capacity of the engine oil, the more it accelerates the cleaning effect. If the oil viscosity is high, the oil circulation speed slows down, reducing the number of times it passes through the filter, and it cannot promptly carry away metal wear particles, carbon particles, dust, and other impurities from the friction surfaces, resulting in poor cleaning performance. Therefore, low-viscosity oil circulates faster and provides better cleaning than high-viscosity oil. More details are as follows: 1. Causes of sludge formation: Carbonaceous substances formed after combustion, gum-like substances generated by lubricant oxidation, metal shavings from friction between parts, and contaminants mixed with water in the lubricant combine to form sludge. 2. Prolonged sludge buildup can suffocate the engine: These sludge deposits and contaminants gradually accumulate on the friction surfaces of the parts, and severe gum formation can cause piston rings to stick, preventing the engine from operating normally and even damaging components. 3. These contaminants must be cleaned from all aspects: This cleaning task is performed by the lubricating oil. Thus, the engine oil carries away contaminants from the friction surfaces and delivers them to the oil pan. When passing through the oil filter, these contaminants are trapped, while the clean oil continues its cleaning function. This cyclic process ensures the parts remain clean and operate normally.
