What grade of engine oil should be used for Changan CS35?
2 Answers
Changan CS35's factory-recommended engine oil model is SL-grade 5W-30. Any engine oil that meets this specification parameter can be used. There is not much difference between brands. Engine oil is an important factor affecting engine performance and service life. The CS35 comes pre-filled with high-quality multi-viscosity oil at the factory, which can be used year-round except in extremely cold climates. 1. Engine oil grade classification: The number before W represents the flow performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after W represents the stability of the oil at high temperatures (i.e., the possibility of thinning). The larger the number, the better the stability. 2. Precautions: When selecting engine oil, pay attention not only to the quality grade but also to the viscosity grade. First, select based on performance grade; then choose the viscosity grade according to temperature and load.
What grade of engine oil is suitable for the Changan CS35? I've also driven this model and initially didn't know better, so I randomly used 10W-40 oil. As a result, cold starts in winter became particularly difficult, and engine noise increased. Later, I checked the owner's manual and found it recommends either 5W-30 or 10W-40, depending on the climate and the vehicle's age. Newer models often use 5W-30 full synthetic oil, which is thinner and flows more easily, making it suitable even in summer. The oil grade is indicated by the first number (5W means good low-temperature fluidity), while the latter part indicates high-temperature viscosity. Choosing the right oil ensures quieter engine operation, reduces wear, and can even save you some money on fuel. Change the oil regularly every 5,000 to 10,000 kilometers—don't neglect it like I did, which led to earlier maintenance intervals. Remember to check the dipstick; the oil level should be in the middle.
