How many miles per gallon does a 2015 6.7 powerstroke get?
There isn’t a single miles-per-gallon figure for the 2015 6.7L Power Stroke. Typical EPA estimates and real-world results vary by drivetrain, axle ratio, cab/bed configuration, tires, and whether you’re towing or carrying a load. In general, diesel-powered heavy-duty pickups from this era deliver roughly in the high-teens mpg combined, with highway numbers often in the low- to mid-20s for light loads and 4x2 configurations.
How mpg varies by configuration
The following figures reflect common EPA estimates for 2015 Ford F-250/F-350 Super Duty models equipped with the 6.7L Power Stroke and an automatic transmission. Real-world numbers can differ based on payload, towing, tire size, gearing, and driving habits.
- 2WD (two-wheel drive): roughly 15 mpg city / 21 mpg highway, about 18 mpg combined.
- 4WD (four-wheel drive): roughly 14–15 mpg city / 19–20 mpg highway, about 17–18 mpg combined.
- With towing or heavy payload: fuel economy can drop into the low- to mid-teens, typically around 12–16 mpg combined depending on weight and terrain.
These figures illustrate a typical range you might see across common configurations. Exact numbers depend on the specific cab/bed combo, axle ratio, tire size, and whether the truck is stock or modified.
Summary
For the 2015 6.7L Power Stroke, expect a combined MPG generally in the high teens under normal use, with highway efficiency around the low to mid-20s for 2WD setups and slightly lower figures for 4WD. Towing and heavy payloads reduce fuel economy further. To know the precise figure for a given truck, check the vehicle’s window sticker or official EPA ratings for that exact configuration.
