I. Product Definition and Technical Background

1. Interpretation of CD+ and 10W-40

• CD+: A specialized classification for military diesel engine oils, indicating enhanced wear resistance, extreme pressure performance, thermal stability, and adaptability to harsh environments. Literature suggests its performance approaches the CF-4 grade.

• 10W-40: A multi-grade viscosity oil balancing low-temperature fluidity (-25°C to -35°C cold starts) and high-temperature viscosity (≥13 cSt at 100°C), suitable for all-weather armored vehicle operations.

2. Technical Standards and Certifications

• Compliance: Chinese Military Standards GJB3937-2000 (General Lubricants for Armored Vehicles) and GJB5038-2003 (Armored Vehicle Diesel Engine Oils). May replace CF-4+ 15W-40 (GJB4369A) and No.16 Tank Engine Oil (Q/SH 018.3207-1986).

• Manufacturers: Shenyang Teli Petrochemical Co.,Ltd

II. Core Performance and Advantages

1. Extreme Environment Adaptability

• Low-Temperature Performance: Pour point ≤ -45°C (tested -56°C), enabling cold starts at -35°C, surpassing standard 10W-40 oils.

• High-Temperature Stability: Flash point ≥ 160°C (tested 186°C), with 13.9 cSt kinematic viscosity at 100°C, meeting heavy-duty transmission demands.

• Anti-Wear Properties: Formulated with highly refined base oils and advanced additives, achieving lower friction coefficients than 5W-30 oils, reducing cylinder-piston wear.

2. Military-Specific Optimizations

• Load-Bearing Capacity: Enhanced extreme-pressure additives for tracked vehicles (e.g., tanks) and heavy-duty drivetrains.

• Corrosion Resistance and Cleanliness: Compliant with GJB3937-2000, reducing engine deposits and extending oil change intervals.

• Compatibility: Replaces multiple military-grade oils (e.g., CD 10W-40, CF-4 15W-40), simplifying logistics.

III. Market Applications and Competitive Analysis

1. Application Scenarios

• Key Platforms: Tracked armored vehicles (e.g., Type 99 tanks), wheeled APCs (e.g., ZBL-08), heavy-duty trucks (e.g., Dongfeng Mengshi), and self-propelled artillery.

• Operating Conditions: Suitable for deserts, alpine regions, coastal zones, and prolonged high-intensity combat.

2. Competitor Comparison

   Product	Advantages	Limitations
   SINOPEC RP4652D	Market leader (70% share), GJB5038-2003 compliance	Restricted procurement channels
   Mobil Delvac 10W-40	Advanced synthetic tech, API CK-4 compliance	Not tailored for armored vehicles, costly
   Armado Synth 10W-40	Extended drain intervals (100,000 km), EU commercial standards	Unverified military compatibility

3. User Feedback

• Shenyang Teli Petrochemical serves 952 military units, with proven battlefield performance.

• SINOPEC RP4652D is the standard oil for 90% of active armored forces.

IV. Usage Guidelines

1. Storage and Handling

• No Mixing: Store separately; compatibility tests required before blending.

• Sealing: Reseal containers post-opening to prevent oxidation.

2. Oil Change Intervals

• Standard conditions: Replace every 500 hours or 10,000 km (per GJB3937-2000).

• Extreme environments: Shorten to 300 hours or 7,000 km (e.g., desert or Arctic operations).

3. Technical Compatibility

• Compatible with electronic fuel injection systems but unsuitable for engines with DPFs.

V. Future Development

1. Technical Upgrades

• Synthetic Formulations: Adopt PAO/ester base oils (e.g., Armado Synth) to improve shear stability.

• Eco-Friendly Solutions: Develop low-ash formulations for China VI-B emission standards.

2. Supply Chain Optimization

• Establish civil-military procurement platforms integrating Shenyang Teli .

• Reduce reliance on SINOPEC via domestic alternatives.

VI. Conclusion and Recommendations

CD+/10W-40 armored vehicle lubricant is the optimal solution for China’s combat platforms, aligning with military specifications. 

Priority Use Cases:

1. Arctic operations (relying on -35°C cold-start capability).

2. Heavy armor units (requiring extreme load resistance).

3. Rapid-deployment forces (needing broad temperature adaptability).

Procurement Advice: Prioritize SINOPEC RP4652D (best standard compliance) or Shenyang Teli Petrochemical (flexible private-sector supply), validated via GJB3937-2000 certification.
