How many miles per gallon does a Ford f250 Turbo Diesel 6.7 PowerStroke get?

In general, the Ford F-250 Super Duty with the 6.7-liter Power Stroke turbo diesel delivers roughly mid-teens to low-20s miles per gallon, depending on configuration and driving conditions. Most recent two-wheel-drive (2WD) models run about 18–19 mpg combined, while four-wheel-drive (4WD) versions typically hover around 17–18 mpg combined.

The exact figure for a given truck depends on factors such as cab and bed configuration, axle ratio, towing or payload, speed, terrain, and overall vehicle condition. This article provides a clear breakdown of EPA estimates by drivetrain and outlines practical considerations that influence real-world fuel economy.

EPA estimates by drivetrain and model year

Before listing the numbers, note that EPA ratings are model-year dependent and vary with cab/bed choices, axle gearing, and whether the truck is configured for 2WD or 4WD. The following ranges reflect typical EPA estimates for recent model years with the 6.7L Power Stroke diesel.

• 2-Wheel Drive (2WD): approximately 15–16 mpg city, 20–21 mpg highway, for a combined around 18–19 mpg.


• 4-Wheel Drive (4WD): approximately 14–15 mpg city, 19–20 mpg highway, for a combined around 17–18 mpg.

These figures provide a practical reference for prospective buyers and current owners. Actual numbers can vary based on configuration, use case, and maintenance.

Key factors that influence mpg on the F-250

Fuel economy for a heavy-duty diesel like the 6.7 Power Stroke is sensitive to how you use the truck. The following factors can push mpg up or down significantly.

• Payload and towing: Heavier loads increase engine work and reduce efficiency.


• Driving conditions: City stop-and-go use lowers mpg more than steady highway cruising.


• Terrain and speed: Steep grades and sustained high speeds reduce efficiency; cruising around 60–70 mph is typically more fuel-efficient than faster driving.


• Maintenance: Regular maintenance—oil quality, air filters, tire pressure, and emission-system upkeep—helps maintain efficiency.

In real-world driving, most owners report mpg that aligns with EPA estimates under light-use and highway cruising, with lower numbers when towing or hauling heavy loads. Expect a broad range from the mid-teens to the low-20s, largely influenced by how the truck is used.

Practical tips to maximize efficiency include planning routes to avoid excessive hills, maintaining proper tire inflation, reducing unnecessary weight, and adhering to a regular maintenance schedule for the diesel system and drivetrain components.

Summary: The Ford F-250 with the 6.7L Power Stroke diesel typically achieves roughly 18–19 mpg combined in 2WD configurations and about 17–18 mpg combined in 4WD configurations, with real-world numbers varying based on payload, towing, terrain, and driving habits. Always consult the exact EPA ratings for your model year and configuration on fueleconomy.gov or Ford’s official specifications to get precise figures.

How long will a Ford 6.7 diesel last?

200,000 to 300,000 miles
How Long Will It Last? With proper care, many truck owners report that their deleted 6.7 Powerstroke engines last 200,000 to 300,000 miles or more.

What is the biggest problem with 6.7 power stroke?

The biggest problems with the 6.7 Powerstroke include fuel system issues, such as CP4 injection pump failure (especially on pre-2020 models), and emissions system problems like clogged EGR coolers and faulty EGT or NOx sensors. Other common concerns are leaks, often from the upper oil pan or the cold-side charge pipe, and issues with the high-pressure fuel pump.

Fuel system 

• Injection pump failure: The Bosch CP4 injection pump on pre-2020 models is a major issue. It can fail due to metal-on-metal contact, sending metal shavings throughout the fuel system and causing extensive damage to injectors, lines, and regulators. 
• Fuel filter housing: The secondary fuel filter housing can leak, particularly the plastic fuel filter housing fitting, which can also be a fire hazard if it breaks. 

Emissions system

• EGR cooler: The EGR cooler is prone to clogging from carbon deposits, which can lead to a loss of power and may eventually require replacement. 
• EGT and NOx sensors: These sensors are known to fail, which can trigger a check engine light or even cause the vehicle to shut down. The middle EGT sensors are the most common failure points.

Leaks and other issues

• Oil leaks: A significant number of leaks are reported, especially from the upper oil pan and front cover, often caused by a clogged crankcase filter that builds excessive pressure. 
• Charge pipe failure: The cold-side charge pipe is a common failure point that can leak, leading to a loss of boost pressure. 
• Exhaust manifold: The exhaust manifold is infamous for cracking, which can cause exhaust leaks, a ticking noise, and a loss of performance. 
• Turbocharger issues: Early models had issues with the turbocharger's ceramic ball bearings, though updates were made in later years.

How many miles per gallon does a 6.7 F 250 diesel get?

A Ford F-250 with the 6.7L diesel engine typically gets 18-20 mpg on the highway and 15-18 mpg in mixed city/highway driving when unloaded. Fuel economy drops significantly when towing, with estimates ranging from 8.9 to 12-15 mpg depending on the load. Real-world mileage is affected by driving style, speed, terrain, and other factors. 
Unloaded driving

• Highway: Expect around 18-20 mpg on the highway under optimal conditions. Some drivers report getting as high as 24 mpg on highways, particularly with the high-output (HO) engine and gentle driving. 
• Mixed/City: You can expect a combined average of 15-18 mpg. 
• Factors: Driving speed has a significant impact. Driving at 80 mph can reduce fuel economy compared to driving at 60-65 mph, where you might see higher mileage.

Towing

• Towing MPG: When towing, fuel economy can drop to 12-15 mpg. 
• Heavier loads: With very heavy loads (e.g., a 17,000 lb 5th wheel), mileage can drop to under 9 mpg.

Other considerations

• High-output (HO) engine: The high-output version of the 6.7L engine offers more power with little to no difference in fuel consumption compared to the standard engine under normal conditions. 
• Engine break-in: New engines may have lower fuel economy until they are broken in. 
• DPF delete: Aftermarket modifications like a DPF delete may increase MPG, but this is not recommended for street use. 

How to get better MPG 6.7 powerstroke?

You can improve 6.7 Powerstroke fuel mileage by changing your driving habits, performing regular maintenance, and making certain modifications. Aggressive driving and excessive idling reduce fuel economy, while driving smoothly, using cruise control, and maintaining proper tire pressure can help. Regular maintenance, such as changing air filters and oil, is crucial, and some drivers see significant gains from engine tuning, a cold air intake, or a DPF delete (though the latter may have legal implications).

Driving habits

• Drive smoothly: Avoid aggressive acceleration and hard braking. 
• Reduce high speeds: Driving at lower highway speeds, like 65 mph instead of 75 mph, can significantly improve mileage. 
• Avoid excessive idling: Let the engine warm up briefly and then drive, rather than idling for extended periods. 
• Use cruise control: Maintain a steady speed on the highway to avoid fluctuations. 

Maintenance and upkeep

• Change filters: Regularly replace the air filter and other maintenance items. 
• Keep up with oil changes: Ensure your engine oil is changed regularly. 
• Check tire pressure: Maintain correct tire pressure, as underinflated tires can decrease fuel efficiency. 

Modifications and tuning

• Engine tuning: Aftermarket tunes can optimize the engine's air-fuel ratio and injection timing for better efficiency. 
• Cold air intake: Upgrading to a cold air intake can improve air density, potentially leading to better fuel economy. 
• DPF delete: Some drivers report significant mileage improvements after removing the Diesel Particulate Filter, but this is often illegal and can have environmental consequences.
