How many miles per gallon does a 2017 Ford F250 diesel get?

In general, the 2017 Ford F-250 equipped with the 6.7-liter Power Stroke diesel delivers around 17 miles per gallon combined, with city and highway figures varying by configuration. Real-world results can differ based on payload, towing, and driving conditions.

The following analysis focuses on typical EPA estimates for common factory configurations, and then explains how real-world mileage can vary in practical use.

EPA estimates by configuration

Below are representative EPA figures for common 2017 F-250 diesel setups. These numbers reflect standard testing conditions and may differ from your actual experience depending on drivetrain, cab style, bed length, and use.

• 2WD Regular Cab / Long Bed: City about 15 mpg, Highway about 21 mpg, Combined around 18 mpg.


• 2WD Crew Cab / Short Bed: City about 16 mpg, Highway about 22 mpg, Combined around 19–20 mpg.


• 4WD Crew Cab / Short Bed: City about 15 mpg, Highway about 20–21 mpg, Combined around 17–18 mpg.

These EPA estimates are a useful baseline, but actual fuel economy depends on how the truck is used. Heavy payloads, towing, and aggressive driving can lower mileage, while steady highway cruising with a modest load can push it higher.

Factors that affect mpg

Several variables have a meaningful impact on fuel economy for the 2017 F-250 diesel. Understanding them can help buyers set realistic expectations and owners optimize efficiency.

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


• Drivetrain and configuration: 4WD typically lowers mpg versus 2WD, and cab/bed choices influence aerodynamics and weight.


• Speed and driving style: Higher speeds and rapid acceleration consume more fuel.


• Terrain and climate: Hilly terrain and extreme temperatures can reduce efficiency.


• Maintenance and fuel quality: Regular maintenance and using appropriate diesel fuel can help preserve economy.

Effective maintenance, prudent towing practices, and mindful driving can help maximize miles per gallon for this heavy-duty pickup.

Summary

The 2017 Ford F-250 diesel generally delivers around 17 mpg combined, with EPA estimates ranging roughly from 15–16 mpg city to 20–23 mpg highway depending on configuration. Real-world results vary widely based on payload, towing, and driving conditions, so check your specific vehicle’s EPA label and factor in typical usage to set accurate expectations.

How do I increase the MPG on my 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.

What is the fuel mileage on a 6.7 Powerstroke vs 6.7 Cummins?

The Ford 6.7L Powerstroke generally gets better highway mileage, typically between 19–20 MPG when unloaded, while the 6.7L Cummins averages around 16–18 MPG. However, the Cummins often performs better under heavy towing loads due to its high low-end torque. Real-world fuel economy can vary significantly depending on factors like model year, vehicle condition, payload, and driving habits.

6.7L Cummins

• Highway MPG (unloaded): 16–18 MPG
• City MPG: Around 12 MPG
• Towing: Stronger under heavy towing loads due to high low-end torque.

6.7L Powerstroke

• Highway MPG (unloaded): Up to 20 MPG
• City MPG: Around 14–15 MPG
• Towing: Often slightly less fuel-efficient when towing heavy loads compared to the Cummins. 

Key considerations

• Load: The 6.7L Powerstroke tends to have an advantage in fuel economy when unloaded, but this gap narrows significantly or reverses when towing heavy loads, where the Cummins' torque becomes a benefit. 
• Model Year: Fuel economy can vary between different model years for both engines due to design updates. 
• Driving Conditions: Urban vs. highway driving, speed, and driving habits will all affect the final MPG. 
• Towing/Payload: When a truck is fully loaded, fuel economy drops for both engines. Some drivers report a full load can bring the MPG down to around 11.2 MPG for either engine, though this is highly variable. 

What 2500 diesel gets the best MPG?

Best MPG 3/4 Ton Diesel Truck
In that world, the frontrunners are the Chevrolet/GMC 2500 Duramax (6.6L), Ford F-250 Power Stroke (6.7L), and Ram 2500 Cummins (6.7L). Unloaded highway results often sit in the 17–20 mpg window, with mixed driving around 15–18 mpg.

How many miles per gallon does a 2017 6.7 Powerstroke get?

A 2017 6.7L Powerstroke gets an average of around 14-17 mpg in mixed city/highway driving, but real-world mileage can vary significantly depending on driving conditions, cargo, and any modifications. Towing heavy loads will decrease fuel economy, with some drivers reporting around 10 mpg while towing heavy, while others get up to 20+ mpg when unloaded and driving conservatively.

Factors influencing MPG:

• Towing: Towing a heavy trailer will significantly reduce your miles per gallon. Expect to see lower numbers, sometimes as low as 10 mpg. 
• Driving style: Aggressive driving and high speeds will lower your average. Gentle, conservative driving, especially on the highway, will yield the best results, potentially reaching over 20 mpg. 
• Tire size: Larger tires, like 37-inch tires, can decrease fuel economy. 
• Modifications: Removing emissions components or adding tunes can increase MPG, though this may void the warranty and is not recommended for everyone. 
• Standard vs. High Output: Some users report slightly better mileage with the high-output (HO) version of the engine. 
• Maintenance: Keeping the truck well-maintained, with clean air filters and fresh oil, can help maintain fuel efficiency.
