What is the Difference Between Synthetic Oil and Mineral Oil?
2 Answers
Synthetic oil and mineral oil differ in the following ways: 1. Manufacturing Process: Synthetic oil is fully synthesized, while mineral oil is based on refined petroleum with added additives; 2. Cost: Synthetic oil has a more complex production process and higher costs, whereas mineral oil is more affordable; 3. Performance: Synthetic oil offers superior high and low-temperature performance, while mineral oil is a more basic type with relatively poorer performance. Engine oil consists of base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of lubricants.
I've been driving for over twenty years and have used various types of engine oil. The main differences between synthetic and mineral oils lie in their source and performance. Mineral oil is directly refined from crude oil, making it more natural and cheaper, but it has poor fluidity in low temperatures. Starting the engine in winter can be difficult, and the engine tends to make loud noises. Synthetic oil, on the other hand, is chemically synthesized in a lab with a more uniform molecular structure. It flows quickly even in cold temperatures, making ignition much easier at zero degrees. It also resists oxidation and degradation at high temperatures, unlike mineral oil, which tends to form carbon deposits and clog engine passages. In terms of lifespan, synthetic oil is more durable and can last up to 15,000 kilometers before needing a change, while mineral oil requires replacement every 5,000 kilometers. In the long run, although synthetic oil is more expensive, it requires less maintenance, reduces engine wear, provides better protection for turbochargers, and can even lower fuel consumption slightly.
