How Often Should You Clean a Car Engine?
1 Answers
Car engines should be cleaned every 20,000 to 40,000 kilometers. Here are the relevant details: The lubrication system cleaning service at 4S shops typically involves adding a cleaning agent through the engine oil filler port before an oil change, keeping the engine running for 5 to 10 minutes, and then draining it along with the old oil. During engine operation, the high-temperature working environment and friction between moving parts can degrade the performance and quality of the engine oil. When the oil's performance and quality deteriorate, its ability to clean the oil passages also decreases, leading to sludge buildup in the lubrication system. In severe cases, this can even clog the oil passages. Therefore, the engine lubrication system requires regular cleaning.
