SJ-SN-SP-SL 5W40

Our factory specializes in the production of 5W-40 viscosity grade automotive engine oil, fully covering the full API quality specifications of SP, SN, SL, and SJ, and can accurately adapt to the lubrication needs of gasoline engines of different years and different technical types.

The core advantages of the product are distinct: First, it is compatible with a wide temperature range and high loads. The 5W viscosity ensures smooth starting in low-temperature environments above -30°C and rapid lubrication of components. The 40# high-temperature viscosity can stably maintain the oil film strength under medium and high load conditions of the engine (such as high-speed driving and heavy load), effectively resist high-temperature shearing, and reduce wear on key components.Secondly, it covers all quality grades. The SP grade is aimed at modern engines such as turbocharging and direct injection, with enhanced resistance to low-speed pre-ignition and anti-wear performance to meet the National VI emission standards; the SN grade is suitable for mainstream models to ensure efficient lubrication and anti-oxidation; the SL and SJ grades are precisely matched to old naturally aspirated engines to provide reliable basic protection; thirdly, it has strong adaptability, especially suitable for vehicles in areas with more complex climates or with medium and high load driving needs, taking into account both protection performance and operational stability.
