1. Product Overview

Teli 8A Jet Engine Oil (code: HP-8A), produced by Shenyang Teli Petrochemical Co., Ltd., is a mineral-based aviation lubricant compliant with Chinese Military Standard GJB 439-1990 (equivalent to the national standard GB 439-1990). Designed for military aircraft equipped with turbojet engines (e.g., fighters, trainers, bombers) and turboprop transport aircraft, it is one of only three domestic products meeting this standard (alongside Kunlun and Sinopec Great Wall). Its long-term stability and proven performance have made it a trusted choice for the Chinese Air Force.

2. Core Technical Parameters & Performance Metrics

1. Physicochemical Properties:

• Temperature Range: -45°C to 130°C (extendable to 135°C per some specifications), with excellent cold-start performance (viscosity ≤6,500 mm²/s at -40°C) and high-temperature stability (flash point ≥140°C, tested at 156°C).

• Viscosity: Kinematic viscosity ≥8.3 mm²/s at 50°C (tested: 8.62 mm²/s) and ≤30.0 mm²/s at 20°C (tested: 28.18 mm²/s). Viscosity-temperature ratio (ν-20°C/ν50°C) ≤70, ensuring lubrication efficacy across wide temperature ranges.

• Oxidation Resistance: Contains composite antioxidants; post-oxidation sediment ≤0.08% and acid value ≤0.25 mgKOH/g (tested: 0.014 mgKOH/g), ensuring extended service life.

2. Safety & Environmental Compliance:

• Low pour point (-55°C, tested: -56°C), density ≤885 kg/m³ (tested: 871.8 kg/m³), and no mechanical impurities or moisture, meeting aviation safety standards.

• Anti-corrosion formulation enhances rust resistance and sealing performance, reducing component wear and extending engine lifespan.

3. Application Scenarios & Market Positioning

1. Key Applications:

• Military: Compatible with Sukhoi and MiG series turbojet engines, widely used in fighters, bombers, and other combat aircraft.

• Civil Aviation: Serves as a blending base oil for turboprop aircraft (e.g., Yun-7, MA60) and covers transport planes and trainers.

2. Competitive Advantages:

• Cost Efficiency: Compared to synthetic hydrocarbon oils (e.g., Type 8B), 8A’s low-cost mineral-based formula meets basic operational needs, ideal for budget-sensitive bulk procurement.

• Supply Chain Coverage: Distributed nationwide via agents like Beijing Luhang Aviation , supporting direct delivery to reduce logistics costs. Custom packaging (15kg/170kg drums) and tax-compliant invoicing are available.

4. Product Comparison & Evolution

1. 8A vs. 8B:

   Parameter	8A (Mineral-based)	8B (Synthetic Hydrocarbon)
   Temperature Range	-45°C to 130°C	-60°C to 150°C
   Base Oil Type	Naphthenic Mineral Oil	Synthetic Hydrocarbon
   Antioxidants	Composite	Enhanced Formulation
   Applications	Conventional military/civilian	Extreme cold/heat environments
   Cost	Lower	Higher

2. Industry Position:

• Dominates the traditional aviation lubricant market alongside Kunlun and Great Wall.

• Maintains stable market share due to mature supply chains and cost advantages, particularly for legacy fleet maintenance.

5. Quality Control & Certifications

• Certifications: Compliant with Military Product Quality System Certification and ISO 9001. Advanced lab equipment (e.g., colorimeter, distillation tester) ensures batch consistency.

• Testing: Covers 12 critical parameters (acid value, ash content, flash point), with some metrics exceeding national standards (e.g., tested acid value is 35% below the limit).

6. Usage & Storage Guidelines

1. Operational Requirements:

• Do not mix with other lubricants; avoid contact with ester solvents or rubber seals.

• Clean fuel tanks thoroughly before refilling to prevent contamination.

2. Storage Conditions:

• Store in cool, dry areas away from heat, flames, and humidity. Shelf life: 3 years.

7. Future Development

• Technology Upgrades: Optimize low-temperature performance (e.g., reducing pour point to -60°C) using insights from 8B’s synthetic hydrocarbon processes.

• Eco-friendly Adaptation: Develop hybrid formulas compatible with emerging bio-based lubricants.

• Global Expansion: Target military markets in "Belt and Road" countries via agent networks.

Conclusion

Teli 8A Jet Engine Oil retains irreplaceability in traditional aviation lubrication due to its wide temperature adaptability, cost-effectiveness, and proven reliability. While synthetic oils gain traction, 8A’s market strategy must balance technological evolution with cost control, leveraging differentiated services to strengthen loyalty among military and civilian clients.
