How many miles per gallon does a Ford F450 Super Duty get?
The Ford F-450 Super Duty’s miles-per-gallon figures depend on the engine and configuration. In general, diesel models return higher highway efficiency, while gas models are typically less fuel-efficient overall. Expect roughly 11–13 mpg combined with gasoline and about 14–17 mpg combined with the diesel, with real-world results varying based on towing, payload, terrain, and drivetrain.
Engine options and EPA ratings
The F-450 is offered with two main powertrains, and EPA estimates vary accordingly. The following options are the most common for recent model years.
- 6.7L Power Stroke V8 Turbo Diesel
- 7.3L Gas V8
EPA figures change with drivetrain and setup (4x2 vs. 4x4, axle ratios, bed length, and whether the vehicle is towing a heavy load). Diesel versions generally show better highway efficiency, while the gasoline option delivers lower overall mpg when not carrying heavy loads. Always check the specific EPA ratings for your exact configuration on the official EPA website or Ford’s showroom data.
In practice, the choice between diesel and gasoline, along with how the truck is used, has the biggest impact on fuel economy. The diesel engine is typically more efficient on open roads and under light-to-moderate loads, while the gas engine’s mpg is usually lower across the board, especially under heavier towing or payload conditions.
Real-world numbers vs. EPA ratings
Actual fuel economy often differs from EPA estimates, particularly when towing or hauling. Diesel F-450s commonly register in the mid-teens to around 20 mpg on highway driving when not towing, with mixed-driving figures generally in the low-to-mid teens. Gasoline-powered F-450s tend to run in the low-teens to around 13 mpg in mixed driving, dipping further under heavy loads. The exact numbers depend on configuration, load, aerodynamics, and driving style.
Factors that affect mpg
Beyond engine choice, several practical factors influence fuel economy on the F-450:
- Towing weight and payload
- Terrain, incline, and driving speed
- Drivetrain (4x2 vs. 4x4) and axle gearing
- Truck maintenance, including air filters, oil, and tire condition
- In-cabin weight, accessories, and aerodynamic drag from equipment
Understanding these factors helps buyers estimate realistic fuel economy for their specific use case rather than relying on a single published number.
Tips to maximize fuel economy
Small, deliberate changes can improve efficiency, especially when the F-450 is not under a heavy load:
- Keep tires inflated to the manufacturer’s recommended pressures for load and speed.
- Drive at steady speeds; use cruise control on highways when appropriate.
- Lighten payload and remove unnecessary cargo when possible.
- Plan efficient routes to minimize stops and idling.
- Maintain the truck through regular service intervals and ensure the fuel system and air filters are clean.
Implementing these practices can yield meaningful gains in real-world driving, especially in non-towing conditions.
Summary
In short, the Ford F-450’s fuel economy hinges on engine choice and usage. Diesel models typically deliver better highway efficiency and higher mpg under light loads, while gasoline versions are less fuel-efficient overall. Real-world results depend heavily on towing, payload, and configuration. For precise numbers, consult the EPA ratings for your exact build and consider how you plan to use the truck to estimate realistic fuel costs.
