What is the MPG of the 6.7 powerstroke?
In short, there isn’t a single MPG figure for the 6.7 Power Stroke. It depends on the model year, drivetrain, payload, and how you use the truck. For most recent Super Duty pickups, typical combined fuel economy sits in the high teens, with higher highway efficiency and lower numbers when towing.
The 6.7-liter Power Stroke diesel, used in Ford F-Series Super Duty trucks (F-250, F-350, and heavier), is built for heavy-duty work. That capability comes with fuel-economy tradeoffs, and EPA ratings vary by configuration. Below is a current snapshot of official estimates and practical considerations for contemporary models.
EPA fuel economy estimates for the 6.7 Power Stroke
Before listing typical numbers, note that EPA ratings depend on whether your truck is two-wheel drive vs. four-wheel drive, cab style, bed length, and axle ratio. The figures below reflect common configurations in latest-generation F-Series Super Duty trucks and are best used for comparison rather than precise predictions for any individual vehicle.
- 2WD models (F-250/F-350 with 6.7L Power Stroke): Combined efficiency generally around 18–20 mpg, with about 15–16 mpg in city driving and 20–23 mpg on the highway. Real-world numbers may drift lower if towing heavy loads.
- 4WD models: Combined efficiency typically around 17–19 mpg, with roughly 14–15 mpg city and 19–22 mpg highway under non-towing use. Towing reduces MPG further, often into the low-to-mid teens.
- With heavy towing or payload: When towing large trailers or carrying significant payload, combined numbers commonly fall into the mid-teens or lower (roughly 12–15 mpg, depending on load, grade, and speed).
Concluding: The exact mpg you’ll see depends on configuration and use. To get precise figures for a specific build, consult fueleconomy.gov or Ford’s official specifications for the exact year, model, and drivetrain.
What affects MPG and how to maximize efficiency
To understand why those numbers vary and how to optimize mpg, consider the following factors. The list highlights the major influences on fuel economy for a heavy-duty diesel pickup with the 6.7L Power Stroke.
- Drivetrain: 2WD generally delivers better highway efficiency than 4WD due to drivetrain losses and weight.
- Towing and payload: Heavier loads dramatically increase engine load and reduce mpg, especially on grades and at higher speeds.
- Drive cycle and speed: Consistent cruising at moderate speeds (e.g., 60–65 mph) favors better highway mileage; rapid acceleration and frequent stopping hurt efficiency.
- Aerodynamics and tires: Payload height, trailer aerodynamics, and current tire size/pressure influence drag and rolling resistance.
- Maintenance: Regular maintenance (air filter, fuel filters, injectors, oil, and turbo health) helps sustain expected MPG.
- Fuel quality and diesel additives: The 6.7L Power Stroke requires clean fuel; poor fuel quality or improper additives can affect efficiency and performance.
Concluding: For the best real-world numbers, track your own truck using a fuel log, and compare against EPA estimates for your exact configuration. Tools like fueleconomy.gov provide official numbers to help you benchmark.
Summary
The Ford 6.7L Power Stroke does not have a single MPG figure; expect combined mpg in the high teens for typical daily driving, dipping lower under towing and heavy payload, and improving on highway stretches. Always verify the exact ratings for your build and use, and remember real-world results will vary with payload, terrain, and driving style.
