Can I change the engine oil myself?

You can change the engine oil yourself, but for the first maintenance of a new car, it is recommended to have it replaced at a 4S shop. Below is relevant information about engine oil: 1. Four-stroke engine oil: The viscosity grade classification of four-stroke engine oil follows the classification of the Society of Automotive Engineers (SAE). The winter oil grades in the SAE lubricant viscosity classification are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 2. Two-stroke engine oil: The viscosity grade classification of two-stroke engine oil also follows the SAE classification. Two-stroke gasoline engine oil has two viscosity grades, namely SAE20 and SAE30. Generally, SAE30 is selected. However, for separate lubrication, use in cold regions, or ultra-light-duty two-stroke engines, SAE20 is used.
