First and second maintenance refers to the abbreviation of the second-level maintenance or second-level servicing of a car. Below is a related introduction to car maintenance: Engine oil change: The main function of engine oil is to provide good lubrication for the engine. Upon reaching the maintenance cycle, basic maintenance requires changing the engine oil to ensure its good performance and the lubrication effect of the engine. The engine oil should be changed according to the car's basic maintenance cycle. Common car maintenance cycles are 5,000 kilometers or 6 months, and 10,000 kilometers or 12 months, whichever comes first. Oil filter replacement: The oil filter, also known as the oil filter element, is mainly used to filter impurities in the engine oil to maintain its performance. After a period of use, its filtering performance will decline. Therefore, when changing the engine oil, the oil filter should also be replaced.
