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.

How Often Should You Replace Your Car's Windshield Wipers?

Generally, car windshield wipers should be replaced every 1 to 2 years. Since wipers are made of rubber material, they will naturally degrade over time with use. Timely replacement is necessary to prevent poor performance during operation, which could affect normal driving. Precautions for using car wipers: 1. Dirty wipers will shorten their lifespan; 2. Dry wipers can scratch the glass; 3. Regular maintenance and cleaning of the wipers are essential. Windshield wipers are tools installed on the front glass of motor vehicles to provide basic cleaning against rain and other debris that may obstruct vision. The key to effective wiper performance lies in: maintaining adequate moisture in the rubber wiper blades. Only with sufficient moisture can the blades retain excellent flexibility, ensuring tight contact with the windshield glass.
