Product Advantages Product Features

A full synthetic engine oil engineered for modern heavy-duty diesel engines in long-haul trucks and fleet vehicles. Its advanced 5W-40 formulation provides exceptional low-temperature cold cranking and rapid lubrication at startup, coupled with robust high-temperature stability and shear protection for extended drain intervals under severe operating conditions.

Engineered for Extreme Pressure: 
Ultra-strong wear resistance and oil film strength guard the engine's core. The ultra-high strength oil film effectively prevents wear on critical components like pistons, cylinder walls, and bearings under extreme cylinder pressure.

Optimized for Long-Haul Efficiency: 
Excellent antioxidant and thermal stability significantly slow oil degradation, supporting extremely long oil change intervals. This means less downtime for maintenance and lower overall operational costs for fleets.

Superior Soot Control: 
Outstanding cleaning dispersibility addresses high soot generation, suspending particles to prevent sludge accumulation and viscosity growth, thereby avoiding filter blockage and keeping the engine clean.

Full-Condition Protection:
 Top-level low-temperature fluidity ensures cold-weather starting, while excellent high-temperature anti-shear performance ensures viscosity stability under continuous high-load conditions.

Applicable to China VI/China V vehicles.
