What type of engine oil should be used for the Besturn X80?

[VonJude]

The original engine oil specification for the Besturn X80 is fully synthetic SM5W40, and brands such as Mobil and Shell can be used. Engine oil replacement cycle: Most foreign engine oils are replaced at 10,000 kilometers. However, due to poor road conditions in China, domestic manufacturers generally recommend replacing the oil earlier, at 7,500 kilometers or even as early as 5,000 kilometers. In reality, as long as the oil remains clear, the oil level does not fall below the minimum mark, and there are no special circumstances, the oil does not need to be replaced so frequently. Functions of engine oil: Cooling and temperature reduction, sealing and leak prevention, cleaning, shock absorption and buffering, lubrication to reduce wear, rust and corrosion prevention, and component protection. Engine oil, also known as motor oil, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve any deficiencies in the base oil's performance.
