Can I change the engine oil by myself?

You can change the engine oil by yourself, but it is recommended to go to a 4S shop for the first maintenance if it's a new car. Here is the relevant introduction about engine oil: 1. Four-stroke engine oil: The viscosity grade classification of four-stroke engine oil applies to the classification of the Society of Automotive Engineers, namely the SAE classification. The winter oil grades of SAE lubricating oil viscosity classification are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W represents 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 applies to the classification of the Society of Automotive Engineers, namely the SAE classification. Two-stroke gasoline engine oil has two viscosity grades, namely SAE20 and SAE30. Generally, SAE30 is selected. If it is separate lubrication, used in cold areas, or for ultra-light load two-stroke engines, SAE20 is used.
