Fuel Efficiency Analysis

Fuel economy for trucks equipped with the Weichai WD615 engine and HW19710 transmission varies based on load, terrain, and driving conditions. In real-world operations typical of Southern California construction and hauling routes:

• Loaded (25–30 tons): 2.8–3.4 km/L (6.6–8.0 mpg)
• Partially Loaded (15–20 tons): 3.5–4.1 km/L (8.2–9.6 mpg)
• Empty Return Trips: Up to 4.5 km/L (10.6 mpg)

The WD615 engine’s high-torque, low-RPM design enables efficient operation in stop-start construction zones and hilly terrains (e.g., I-8, I-15 corridors). The HW19710 transmission’s close-ratio gearing allows optimal engine speed management, reducing fuel consumption by up to 7% compared to older 5- or 6-speed units when operated by trained drivers.

Note: These trucks predate advanced telematics and engine management systems. Retrofitting with aftermarket fuel monitoring and GPS fleet tracking can improve utilization efficiency by 10–15%.

---

Load Capacity & Structural Suitability

Trucks in the San Diego used market with the above configuration are typically 6×4 rigid or tractor units, designed for:

• Heavy equipment transport (e.g., excavators, loaders)
• Aggregate, sand, and gravel hauling
• Flatbed and drop-deck trailer operations

The dual 13-ton rear axles and robust ladder frame (≥8+8 mm steel) support sustained operation at 85–90% of GVWR without accelerated frame fatigue. The 12.00R20 tires (18-ply rating) provide high puncture resistance and load stability on rough job-site terrain, though operators should inspect for sidewall cracking and tread wear—common issues in coastal climates due to salt exposure and heat aging.

---

Operational Recommendations

• Maintenance Priority: Monitor Weichai injector performance and turbocharger health; common issues after 600,000 km.
• Transmission Care: Use SAE 85W-90 GL-5 gear oil; inspect shift forks and synchronizers during clutch replacements.
• Tire Management: Rotate every 25,000 km; maintain 90–100 psi for optimal wear and fuel economy.
• Compliance: Verify smog and CARB compliance for California operation—many pre-2010 units require retrofit or retirement under current regulations.

---

Conclusion: Used trucks in the San Diego market featuring the Weichai WD615 engine and HW19710 transmission offer proven mechanical reliability and high load capacity at competitive acquisition costs. While not compliant with modern emission standards, they remain viable for off-road and private-site applications where fuel efficiency, durability, and parts availability are prioritized.
