Fuel Efficiency Analysis

Fuel economy in used trucks equipped with the Weichai WD615 and HW19710 transmission is highly dependent on load profile, terrain, and driver behavior. Under typical Oklahoma construction and regional haul conditions:

• Loaded Operation (25–30 tons GVW): 4.8–5.6 mpg (41.5–48.5 L/100km)
• Partially Loaded (15–20 tons): 5.8–6.5 mpg (36.2–40.7 L/100km)
• Empty Return / Light Duty: Up to 7.0 mpg (33.6 L/100km)

The WD615 engine features electronically controlled unit pump (EUP) injection and optimized combustion chambers, contributing to efficient fuel use even under sustained high-load operation. Fleet telemetry data from Oklahoma-based operators indicates an average 12–15% fuel savings compared to older Cummins ISM platforms when maintained per schedule.

Note: Use of biodiesel blends (B5–B20) is compatible; however, long-term use above B10 without filtration upgrades may impact fuel system longevity.

---

Load Capacity & Operational Suitability

These trucks are engineered for maximum payload efficiency in demanding environments:

• Max Payload Capacity: ~22,000–24,000 lbs (10–11 tons) on tri-axle configurations
• Dump Body Compatibility: Up to 20–25 yd³ volumetric capacity (aggregate, soil, asphalt)
• Gradeability: >30% on low-traction surfaces (4×2 variants); >45% with 6×4 configurations

The combination of high rear axle load ratings (13T each) and robust frame rails (300–320 HB steel) ensures minimal frame flex and extended service life under repetitive heavy loading. Oklahoma’s network of county roads and oilfield access routes places high demand on suspension and drivetrain durability—these platforms have demonstrated mean time between failures (MTBF) exceeding 18,000 hours when maintained properly.

---

Recommendations for Fleet Managers

1. Prioritize trucks with documented service history, especially oil analysis and transmission fluid change logs.
2. Inspect axle seals and differential breathers—common failure points in muddy or flooded site conditions.
3. Verify ECU calibration—some units may be reprogrammed for higher output; factory 336–380 hp settings offer best longevity.
4. Upgrade to radial 12.00R20 tires where available—improves fuel economy by 3–5% and extends tread life by 20–30%.
