What type of oil is used for a new car?

[LeAmy]

New cars generally use oils such as 0W-20, 5W-20, or 5W-30. The specific type should be confirmed by referring to the relevant user manual. Oil selection: When choosing oil, it's not about selecting the most expensive one but rather about choosing the most suitable oil based on the characteristics of the car's engine and your usual driving habits. Oil can be categorized by the type used in winter and the type used in summer. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to select oil with a superior low-temperature viscosity grade. Oil grades: Oil grades are classified by quality and viscosity. Oils for gasoline engines are usually denoted by the letter "S," while oils for diesel engines are denoted by the letter "C."
