   Kinematic Viscosity (-45°C)	≤3,500 mm²/s	GB/T 265
   Flash Point (closed-cup)	≥140°C	GB/T 261
   Pour Point	≤-60°C	GB/T 510
   Acid Number	≤0.04 mgKOH/g	GB/T 7304

III. Application Scenarios

1. Aviation Use

• Military: Turbojet engines in J-20 stealth fighters, H-6K bombers, and trainer aircraft .

• Civil Aviation: Auxiliary systems of C919 passenger jets and helicopter gearboxes .

2. Industrial Use

• High-temperature equipment: Gas turbines, high-speed compressors .

• Extreme environments: Polar exploration machinery, high-altitude hydraulic systems .

IV. Storage & Usage Guidelines

1. Critical Precautions

• Do NOT mix with 8A (petroleum-based) or other oils to avoid additive conflicts .

• Color change under prolonged UV exposure is normal and does not affect performance .

2. Storage Conditions

• Store in cool, dry, ventilated areas away from direct sunlight .

• Seal containers tightly to prevent moisture/contaminant ingress .

V. Procurement & Authentication

1. Authorized Suppliers

• Direct Distributors: certified by CNPC .

• Packaging: 170 kg/barrel with anti-counterfeit labels and batch-specific QR codes .

2. Anti-Counterfeit Measures

• Verify CNPC’s official certification via 400-810-9886 hotline or Kunlun’s website .

• Request third-party test reports (focus on viscosity and pour point) .

VI. Comparison with 8A

Summary

Kunlun 8B aviation lubricant is a high-performance synthetic hydrocarbon oil optimized for extreme-temperature aviation systems. Its superior low-temperature fluidity (-60°C) and oxidation resistance make it critical for modern military and industrial applications. Always procure through CNPC-authorized channels and adhere to strict usage protocols to ensure operational safety
