Is it necessary to replace the oil filter when changing the engine oil?
1 Answers
Replacing the engine oil requires changing the oil filter. Here are the relevant details: 1. Function of the oil filter: The oil filter removes impurities from the oil circulating in the lubrication system. After the engine runs for a period, it generates some impurities. 2. There are mainly two types of impurities: one is metal shavings from engine component wear during operation, and the other is black sludge-like organic matter formed by chemical changes in the engine oil under high-temperature conditions during engine operation. These impurities mix with the engine oil and circulate through the lubrication system.
