NISSAN ATF NS-3

The NISSAN ATF NS‑3 specification is Nissan's requirement for automatic transmission fluids, developed to ensure stable operation of modern automatic gearboxes, including 7‑speed and CVT systems, installed in gasoline and diesel Nissan models (e.g., Qashqai, X‑Trail, Patrol, Serena). Technically, NS‑3 requires a certain viscosity level (approximately 7.5 cSt at 100 °C), high thermal stability, excellent anti‑foam properties and a controlled friction coefficient, which guarantees smooth and rapid gear shifts without excessive wear of gear teeth and torque converters. Oil that meets NS‑3 is compatible with electronic transmission control systems and contains no components that harm catalysts or DPFs, so it can be safely used in vehicles with after‑treatment. Compliance with this specification provides protection against overheating, noise reduction and maintains the claimed fuel economy, making it an optimal choice for technicians and drivers seeking OEM‑level protection for their Nissan transmissions.
