What type of engine oil is best for the Changan CS35?

[AbelRose]

For the Changan CS35, it is recommended to use SL-grade 5W-30 viscosity engine oil. The required oil volume is 3.4L. After filling, the oil level on the dipstick should be between the MIN and MAX marks, neither below MIN nor above MAX. Note that engine oil should only be added when the engine is cool. Relevant details are as follows: 1. The '5W' indicates low-temperature viscosity; the smaller this number, the better the oil's fluidity. The '30' represents high-temperature viscosity; the larger this number, the higher the oil's viscosity and the better its sealing properties. 2. Higher oil viscosity is not always better. If the oil's viscosity is too high, it can also affect the engine. Higher viscosity means relatively poorer fluidity, which may prevent the oil from promptly covering all engine components, thus failing to fully utilize the oil's functions.
