What is the MPG of a 6.7 F-250 diesel?
Typically, a Ford F-250 with the 6.7-liter Power Stroke diesel posts about 14–16 miles per gallon in city driving and roughly 19–23 miles per gallon on the highway, with combined fuel economy around 17–20 mpg. Exact figures depend on the model year, cab/bed configuration, whether it’s 2WD or 4WD, and how heavily the truck is loaded or towing.
The 6.7L Power Stroke is a turbocharged V8 designed for heavy towing and payloads. Its fuel economy reflects the truck’s size and purpose: high torque and stout capabilities come with greater fuel consumption under load. EPA ratings vary by configuration and year, and real-world mpg can differ based on driving conditions and usage. The following sections break down what drives those numbers and what owners typically see in recent model years.
What affects mpg on a 6.7L F-250
Several factors determine actual mpg in daily use. The following list highlights the biggest influences and how they typically impact efficiency.
- Drivetrain: two-wheel drive (2WD) vs four-wheel drive (4WD). 4WD versions generally get lower mpg due to drivetrain losses and higher weight.
- Cab and bed configuration: Crew Cab vs Regular/SuperCab, short vs long bed; longer wheelbase and heavier builds tend to lower mpg, especially when towing.
- Payload and towing: pulling a trailer or hauling heavy loads increases engine effort and reduces mpg.
- Driving conditions and style: city stop-and-go reduces mpg; steady highway speeds improve mpg; aggressive acceleration or high speeds lower mpg.
- Terrain and wind: hills, mountains, and headwinds reduce mpg.
- Maintenance and condition: properly inflated tires, clean air filters, and well-maintained engine help fuel economy; poor maintenance hurts mpg.
Understanding these factors helps explain why two identical trucks can show different mpg in real-world testing.
Typical ranges by configuration (recent model years)
EPA fuel economy labels for recent model years show that highway efficiency is generally higher than city efficiency, and combined mpg typically falls in the high teens to around 20 mpg. Specific figures vary by year and build, but the ranges below reflect common values reported by EPA and Ford for 6.7L Power Stroke F-250s with different drive types and configurations.
- Highway mpg commonly sits in the low- to mid-20s for 2WD configurations and slightly lower for 4WD.
- City mpg is typically in the teens (often upper teens), with reductions when towing or under heavy load.
- Combined mpg generally ranges from about 17–20 mpg, depending on drivetrain and payload.
Note: For exact EPA numbers, refer to the window sticker or the EPA Fuel Economy site for the specific model year, cab configuration, bed length, and drivetrain you’re considering.
Tips to maximize mpg in a 6.7L F-250 diesel
Even with a heavy-duty work truck, practical driving and upkeep can improve fuel economy. Consider these strategies when evaluating a 6.7L-powered F-250.
- Choose a configuration that minimizes weight and drivetrain losses when possible (2WD and lighter cab/bed variants tend to get better mpg).
- Maintain tire pressure and engine health; regular maintenance improves efficiency.
- Plan efficient routes and moderate speeds; using cruise control on highways can help maintain steady fuel economy.
- Use proper towing equipment and techniques; be mindful of payload and trailer weight to avoid excessive engine work.
In practice, owners measuring mpg over daily use will see a range around these figures, especially when towing or hauling heavy loads.
Bottom line
The 6.7L Power Stroke-equipped F-250 is not designed for top-tier fuel economy. It delivers solid highway economy for a heavy-duty diesel and excels at towing and payload capacity. Expect roughly 14–16 mpg in city driving and about 19–23 mpg on the highway, with combined figures typically in the high teens to around 20 mpg depending on configuration and usage. Always check the model-year EPA ratings for the exact configuration you’re considering.
Summary: The 6.7L F-250 diesel yields around 17–20 mpg overall in typical use, with highway numbers favored over city driving. Real-world results depend on drivetrain, cab/bed choice, towing, payload, terrain, and maintenance. For precise numbers, reference the EPA window sticker or the official EPA ratings for the exact build and year you’re evaluating.
