What kind of engine oil should be used for Changan CS75?

[KateAnn]

Changan CS75 should use engine oil that meets the GB11121 standard with a quality grade of SL or above and a viscosity grade of 5W-30, depending on the temperature. Below is the relevant introduction: 1. Engine oils on the market can be simply divided into mineral oil and synthetic oil based on their base oil. Synthetic oils are further divided into: full synthetic and semi-synthetic. 2. Among them, full synthetic oil is the highest grade. The main differences between them are: synthetic oil can be used in a wider temperature range, has a longer service life, and is more expensive; for the same oil film requirements, synthetic oil can achieve the goal with lower viscosity, while mineral oil requires a relatively higher viscosity to meet the same requirements. 3. Depending on the actual usage, consider adding combustion improvers and additives such as fuel system cleaners to help remove carbon deposits.
