How Often Should You Change the Oil in a Newly Purchased Sedan?

[SanGenesis]

For a newly purchased sedan, it is recommended to change the oil within the first 2,000 kilometers. After that, perform regular maintenance every 5,000 kilometers, during which both the engine oil and oil filter must be replaced. The air filter is suggested to be replaced every 5,000 to 10,000 kilometers, as not changing it frequently can significantly impact engine lifespan and fuel consumption. Engine oils are categorized into three types: mineral oil, semi-synthetic oil, and full-synthetic oil. Among these, full-synthetic oil can adapt to a wider temperature range compared to semi-synthetic oil, has a longer service life, and is less prone to oxidation. It should be replaced every 8,000 to 10,000 kilometers. In the same working conditions, full-synthetic oil can protect the engine effectively with lower viscosity.
