Do Engine Oil and Oil Filter Need to Be Replaced Together?
1 Answers
Engine oil and oil filter must be replaced together. The reasons for replacing engine oil and oil filter together are as follows: 1. Not replacing the oil filter will cause it to clog due to sediment buildup, allowing contaminants to enter the engine directly and accelerating component wear. 2. Replacing only the engine oil without replacing the oil filter will allow contaminants from the old filter to re-enter the fresh oil circulation, rendering the oil change meaningless. The functions of the oil filter are as follows: 1. The oil filter's role is to filter out impurities in the engine oil circulating through the lubrication system. 2. The replacement cycle for the oil filter is approximately 5,000 km. During vehicle use, if mineral oil is used, it should be replaced along with the engine oil. If the filter does not have excessive contaminants, the usage cycle can be considered for extension.
