SJ-SN-SP-SL 5W30

We specialize in the production of 5W-30 viscosity grade automotive motor oils, fully covering the full API quality specifications of SP, SN, SL, and SJ, and can accurately match the lubrication needs of gasoline engines of different years and different technical types.

The core advantages of the product are outstanding: First, it has strong adaptability to a wide temperature range. The 5W viscosity ensures smooth starting in low-temperature environments above -30°C and quickly forms a lubricating film; the high-temperature viscosity of No. 30 can maintain a stable oil film under medium and high-temperature engine conditions, taking into account daily commuting and medium-load driving protection; second, 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 wear, meeting 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 adapted to old naturally aspirated engines to provide reliable basic protection; third, it has excellent balanced performance, taking into account lubrication protection and operating resistance control, helping to improve engine power response and fuel economy.
