What are the components of engine oil?
1 Answers
Engine oil components: Engine oil consists of base oil and additives. For mineral oil, the base oil is refined from petroleum; for fully synthetic oil, the base oil is artificially synthesized. Engine oil is known as the lifeblood of the engine, serving functions such as lubrication, cleaning, sealing, heat dissipation, buffering, and rust prevention. There are three types of engine oil: fully synthetic oil, semi-synthetic oil, and mineral oil. Engine oil also contains additives that enhance its performance, with common additives including antioxidants and dispersants. Engine oil needs to be replaced regularly. If used for an extended period without replacement, the oil will oxidize and deteriorate, leading to a decline in its lubricating performance and increased engine wear.
