How many MPG does a Ford F350 diesel get?

The Ford F-350 with the 6.7-liter Power Stroke diesel typically posts around 12–15 miles per gallon in city driving and about 18–21 mpg on highways, with a combined figure generally in the mid-teens to high-teens. Actual results vary widely based on configuration and use.

What influences the mpg numbers on a heavy-duty diesel pickup

The F-350’s mileage is not a single, fixed figure. Drivetrain choices, cab and bed styles, payload and towing loads, axle gearing, tire size, and even model year can push the numbers up or down. Below are the main factors people consider when estimating fuel economy.

• Drivetrain: 4x2 versus 4x4 affects efficiency, especially in stop-and-go city driving and with heavy towing.


• Cab and bed configuration: Crew Cab and long-bed versions typically weigh more and can lower mpg compared with a regular cab, affecting highway economy.


• Payload and towing: Heavier loads demand more engine work and erode mpg, particularly at highway speeds and on grades.


• Tire size and gearing: Larger tires and taller gears can reduce mpg due to higher rolling resistance and engine RPM.


• Transmission and model year: Updates in gearing, tuning, and software can improve efficiency slightly or impact towing performance.


• Driving conditions and habits: City driving, frequent starts, hills, altitude, and maintenance all influence real-world numbers.

Understanding these factors helps explain why mpg can swing across a wide range for the same model year.

Typical mpg ranges by common configurations

For planning purposes, here are representative ranges for common 6.7L Power Stroke diesel builds. Exact numbers depend on the specific options and the EPA window sticker for your vehicle.

• 4x2, Regular Cab, Long Bed, 6.7L Power Stroke Diesel: City roughly 12–14 mpg; Highway roughly 19–23 mpg; Combined roughly 15–18 mpg.


• 4x4, Crew Cab, Short Bed, 6.7L Power Stroke Diesel: City roughly 12–13 mpg; Highway roughly 17–21 mpg; Combined roughly 15–17 mpg.

These figures are estimates based on recent model years and EPA guidelines. Your actual on-road mileage may differ depending on load and usage.

Summary

The Ford F-350 diesel generally delivers mid-teens to low-20s on highways with lighter loads, while city driving and heavy towing/payload can push mpg lower. For the most precise figure, consult the EPA ratings for your exact configuration and year, and consider real-world testing or trip-computer measurements to gauge typical performance.

How many miles per gallon does a 6.7 L V8 diesel get?

A 6.7L diesel engine's MPG varies significantly, but generally ranges from 14 to 21 MPG combined. Unloaded highway driving typically yields the best results, with figures often between 16 and 21 MPG, while city driving is lower. Towing or carrying heavy loads will reduce mileage significantly, with some reports showing as low as 10 MPG under heavy towing conditions. 
Factors that affect MPG

• Driving conditions: Highway driving is much more efficient than city driving. 
• Towing and payload: Hauling heavy loads dramatically decreases fuel economy. For example, towing a 17,000-pound fifth wheel can result in around 10 MPG. 
• Engine and vehicle specifics: Different manufacturers (like Ford's 6.7L Power Stroke vs. Cummins 6.7L) and vehicle models can have different ratings and performance. 
• Driving habits: Aggressive driving, higher speeds, and terrain can all impact mileage. 
• Vehicle maintenance: A properly maintained engine will perform more efficiently. 
• Fuel price: Diesel fuel is often more expensive than gasoline, which can negate the fuel economy benefits. 

What is the gas mileage on a 6.6 L 8 cylinder turbo diesel engine?

A 6.6L V8 turbo diesel engine typically gets 15-18 MPG combined, but can vary based on driving conditions and vehicle model. Highway driving may see results closer to 17-21 MPG, while city driving is generally lower. Towing a heavy load will significantly decrease fuel economy, potentially dropping it to around 10 MPG or less.

Estimated MPG by driving condition

• Combined: 15-18 MPG
• Highway: 17-21 MPG
• City: 13-18 MPG
• Towing: As low as 10 MPG with heavy loads 

Factors that influence MPG

• Towing and hauling: Adding significant weight will reduce fuel economy. 
• Driving habits: Aggressive acceleration and braking, or higher speeds, can lower MPG. 
• Vehicle model: The specific truck model (e.g., Chevy Silverado, GMC Sierra) and its configuration (e.g., cab size, bed length) can affect efficiency. 
• Terrain and conditions: Hilly roads or stop-and-go traffic will decrease MPG compared to flat, steady highway cruising. 

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. 

How many mpg does a F350 diesel get?

Normally, I usually get like 14-15 mpg empty/light towing/tame driving, and 8-13 mpg towing and aggressive/high speed driving, depending on towing weight. I've towed up to 14.5k lb tag hitch and 19k lb gooseneck. It has an AFE oiled cone air filter in a cold air intake and 4" straight pipe exhaust out the side.
