Fuel Efficiency Analysis

Fuel economy in this class of used trucks is heavily dependent on application and maintenance history. Under mixed-use conditions (60% highway, 40% off-road/construction site):

• Average Fuel Consumption: 28–34 L/100 km (6.9–8.3 mpg US)
• Optimal Range (Highway): 24–27 L/100 km (8.7–9.8 mpg US)
• Loaded Off-Road: 35–42 L/100 km (5.6–6.7 mpg US)

The Weichai WD615 engine, while not as refined as Western counterparts, delivers acceptable fuel efficiency when paired with the HW19710 transmission, particularly when operated within the 1,400–1,800 rpm torque band. Proper injector calibration, clean air filters, and use of SAE 15W-40 CK-4 oil are critical to maintaining optimal BSFC (Brake-Specific Fuel Consumption).

Fleet managers should consider retrofitting with aftermarket fuel monitoring systems to track consumption trends and identify underperforming units.

---

Load Capacity & Operational Suitability

These trucks are engineered for high-cycle, high-payload applications typical in Texas construction sectors:

Configuration	Max Payload Capacity	Typical Use Case
6×4 Dump Truck	18,000 – 22,000 kg	Aggregate hauling, site excavation
Concrete Mixer	8–10 yd³ (6–8 m³)	Ready-mix delivery, road base work
Lowboy/Flatbed	25,000 – 30,000 kg	Heavy equipment transport (excavators, etc.)

The 26-ton Gross Axle Weight Rating (GAWR) on tandem axles, combined with robust 12.00R20 18PR tires, allows for sustained operation at or near maximum payload. However, tire wear accelerates significantly when consistently loaded above 90% of GVWR on unpaved surfaces.

---

Summary & Recommendations

Used trucks in the San Antonio market equipped with Weichai WD615 engines, HW19710 transmissions, and 12.00R20 tires offer a cost-effective solution for construction fleets requiring high durability and repairability. While fuel efficiency lags behind newer EPA-compliant Western models, lifecycle costs remain competitive due to:

• Low initial acquisition cost ($28,000–$48,000 USD, depending on year and condition)
• Wide availability of spare parts (Weichai/HW components stocked regionally)
• Proven performance in hot, arid environments

Recommendations:
– Conduct pre-purchase engine compression and transmission end-play tests
– Verify axle oil condition and differential backlash
– Inspect frame rails for stress cracks near suspension mounts
– Prioritize units with documented service history and recent clutch overhaul

These specifications reflect the baseline for reliable asset integration into medium-duty construction logistics fleets operating in South Texas.
