SJ-SN-SP-SL 20W50

We specialize in producing 20W-50 viscosity grade automotive engine oils, covering all API quality specifications including SP, SN, SL, and SJ, and can precisely adapt to the lubrication needs of gasoline engines in high-load, old models, and high-temperature environments.

The product’s core advantages are prominent: First, it offers strong protection against high temperatures and high loads, with a 20W viscosity ensuring normal starting in environments above -15°C; the 50# high-temperature viscosity can maintain a stable oil film under high engine speed and high load conditions (such as heavy loads and long-distance highways), resist high-temperature shear, effectively reduce wear on key components such as pistons and crankshafts, and prevent oil from becoming thinner and failing due to high temperatures; second, it is compatible with all quality grades, with the SP grade targeting some modern high-load engines, enhancing wear and oxidation resistance; the SN grade is suitable for mainstream high-load models, ensuring efficient lubrication; and the SL and SJ grades are precisely matched to older naturally aspirated engines, filling component wear gaps, reducing oil leakage, and maintaining stable oil pressure.Third, it has strong environmental adaptability and is especially suitable for subtropical and tropical regions, or vehicles commonly used for carrying goods and climbing slopes, providing long-term and reliable protection for the engine.
