SJ-SN-SP-SL10w40

We specialize in the production of 10W-40 viscosity grade automotive engine oils, 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 product has distinct core advantages: First, it is compatible with a wide temperature range and high loads. The 10W viscosity ensures smooth starting in low-temperature environments above -25°C and quickly lubricates components. The 40# high-temperature viscosity can maintain a stable oil film under medium-to-high load conditions (such as high-speed driving and heavy loads) in the engine, resist high-temperature shear, and reduce wear on key components such as pistons and crankshafts. Second, it covers a full range of quality grades. The SP grade is designed for modern engines such as turbochargers and direct injection engines, enhancing resistance to low-speed pre-ignition and wear, and meeting China VI emission standards. The SN grade is suitable for mainstream models, ensuring efficient lubrication and anti-oxidation. The SL and SJ grades are precisely matched to older naturally aspirated engines, providing reliable basic protection.Third, strong environmental adaptability, especially suitable for temperate and subtropical regions, taking into account daily commuting and medium-to-high load driving needs, balancing protection performance and operational stability
