What type of engine oil is used in the Haval H6?
1 Answers
Haval H6's factory-recommended engine oil model is CI-4 with a viscosity of 15W-40. Additional information: I. Classification of engine oil: 1. Engine oils are categorized into winter-use and summer-use oils based on viscosity. Winter-use oils include SAE0W, SAE5W, SAE10W, SAE15W, SAE20W, SAE25W, where 'W' stands for winter. The smaller the number before 'W', the lower the low-temperature viscosity, making it suitable for colder environments. Summer-use oils include SAE20, SAE30, SAE40, SAE50, where larger numbers indicate higher viscosity, suitable for higher ambient temperatures. 2. The API classification method divides engine oils into two series: S and C. Gasoline engine oils belong to the S series, currently including SG, SJ, SL, SM, SN grades. Higher grades offer better performance and are more suitable for newer technology engines. Diesel engine oils belong to the C series, currently including CE, CF, CH, CI grades in China. Higher grades provide better lubrication and cleaning effects. II. Functions of engine oil: 1. Lubrication: Engine oil forms a continuous oil film between all friction surfaces of moving parts to reduce friction. 2. Cooling: During circulation, engine oil flows over the working surfaces of parts, lowering their temperature. 3. Cleaning: The flow of lubricating oil washes away dirt generated on the working surfaces of parts. 4. Sealing and leakage prevention: Engine oil can form a seal between piston rings and pistons, reducing gas leakage and preventing external contaminants from entering.
