How many miles per gallon does a 7.3 L F250 get?
Typically about 12–15 mpg combined for the 7.3 L Ford F-250, with the exact figure depending on year, drivetrain, and usage.
In this article, we break down the factors that influence fuel economy for Ford’s 7.3-liter gas V8 in the F-250 Super Duty, explain the EPA estimates, and offer guidance on what to expect in real-world driving, including when towing or hauling payloads.
EPA estimates by configuration
The following ranges reflect typical EPA estimates for commonly configured F-250s with the 7.3L gas engine. Exact numbers depend on model year, 2WD vs 4WD, axle ratio, and transmission options. For the official figure, consult the EPA window sticker or FuelEconomy.gov for your exact build.
- Two-wheel drive (2WD) with standard gearing (roughly 3.55–3.73): about 12 mpg city / 17 mpg highway / 14–15 mpg combined.
- Four-wheel drive (4x4) with heavier gearing: about 11 mpg city / 16 mpg highway / 13–14 mpg combined.
Conclusion: These EPA estimates provide a ballpark for planning, but individual results can vary based on year, configuration, and driving conditions.
Real-world factors that influence mpg
Several practical factors influence fuel economy for the 7.3L F-250 beyond drivetrain. Understanding them helps set expectations for daily use and towing scenarios.
- Towing and payload significantly reduce mpg, especially in urban stop-and-go driving or when trailer brakes are engaged.
- Driving conditions—wind, hills, altitude, and road surface—affect efficiency.
- Maintenance, tire pressure, and aerodynamics (including trailer) matter for highway efficiency.
- Transmission choice and gearing influence efficiency at various speeds and load levels.
Bottom line: If you routinely tow heavy loads, plan for mpg toward the lower end of the range; highway-only, light-load driving tends to stay closer to the upper end.
Notes on model year and updates
Ford introduced the 7.3L “Godzilla” V8 to the Super Duty lineup in 2020, with ongoing refinements in newer model years and pairing it with a 10-speed automatic in most configurations. While the engine remains primarily the same, changes to axle gear, transmission tuning, and vehicle weight across years can shift mpg slightly. Always check the exact window sticker or FuelEconomy.gov entry for your specific build.
Summary
The 7.3L Ford F-250 generally delivers about 12–15 mpg combined, with highway mileage often higher and city driving lower. Towing, payload, and driving conditions can push mpg downward, sometimes significantly. For precise figures, reference the EPA ratings for your exact model year and configuration or consult the vehicle’s window sticker.
