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.

As a new driver who just got my license, I initially heard that mineral oil is cheap and cost-effective, but after trying it myself, I found synthetic oil suits modern cars better. Mineral oil is refined from traditional petroleum with a simple base, and it doesn’t offer much engine protection under high temperatures. Synthetic oil, on the other hand, is artificially engineered, delivering more stable performance, quicker engine response at startup, and noticeably smoother acceleration. Especially in winter when temperatures drop, mineral oil makes the engine struggle to start, while synthetic oil fires up in seconds. It also provides better wear resistance, keeps the engine internals cleaner, and extends its lifespan. Although it costs about 30% more, the oil change interval is twice as long, making it more economical and hassle-free in the long run while reducing maintenance issues. For daily commutes or highway driving, synthetic oil is highly recommended for an enhanced experience.

From experience, mineral oil is economical and practical, but synthetic oil has made significant advancements. Mineral oil is derived from natural petroleum, prone to aging and requires frequent changes, offering average engine protection. Synthetic oil, a product of chemical processes, excels in low-temperature fluidity and high-temperature stability. It keeps the engine interior cleaner with less sludge buildup. The extended oil change intervals make it more convenient and hassle-free. Maintenance costs are reasonable.

When making family car decisions, I compared engine oils: mineral oil is low-cost but mediocre in performance, with slow starts in winter posing potential risks. Synthetic oil offers stronger protection, quicker cold starts, quieter engine operation, and maintains effectiveness at high temperatures. This enhances driving safety, especially when traveling with children. The engine stays cleaner with fewer malfunctions, requiring maintenance only at longer intervals. Although slightly more expensive, it offers better value for money. Choosing synthetic oil is wise, reducing unexpected breakdowns.
