How often should Nissan's super fully synthetic engine oil be changed?

[VanKayden]

Nissan's super fully synthetic engine oil should be changed every 10,000 kilometers. Fully synthetic engine oil has neatly arranged molecules, providing better cleanliness, thermal stability, oxidation stability, low-temperature stability, and shear resistance. It offers superior protection and performance, helping the engine maintain an ideal operating condition, preventing wear, keeping the engine clean, ensuring smooth starts, preventing rust, and effectively reducing fuel consumption and exhaust emissions. The primary functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine, neutralize acids produced by fuel and lubricant oxidation (detergents), improve piston ring sealing, and cool the engine by carrying away heat from moving parts.
