EPA Fuel Economy: 19 MPG Combined

The 2024 Ford F-350 6.7L Power Stroke Diesel Crew Cab 6.75ft delivers a combined EPA fuel economy rating of 19 MPG, making it a respectable choice in the heavy-duty diesel truck segment. This combined figure represents an average of city and highway driving, providing fleet managers and individual owners with a realistic expectation of what they’ll see at the pump. The 6.7L Power Stroke Diesel engine is engineered to balance raw power with fuel efficiency, a challenging equation in the super-duty truck class where towing capacity and payload often take priority.

Diesel engines inherently offer better fuel economy than their gasoline counterparts, and the F-350’s Power Stroke platform has been refined over years of development to maximize efficiency without sacrificing the performance that defines Ford’s heavy-duty lineup. The 6-speed automatic transmission works in harmony with the diesel engine to optimize fuel consumption across various driving conditions, allowing the truck to achieve its 19 MPG combined rating under EPA testing standards. For owners who prioritize capability and fuel efficiency, this combination represents a meaningful advantage in operating costs over the truck’s service life.

City vs Highway Performance

The 2024 F-350 achieves 17 MPG in city driving and 21 MPG on the highway, a difference that reflects typical driving dynamics across different environments. City driving involves frequent acceleration, deceleration, and idling, all of which demand more fuel consumption. The 17 MPG city rating acknowledges the realities of navigating traffic, traffic lights, and stop-and-go conditions that characterize urban and suburban driving patterns. Highway driving, by contrast, allows the diesel engine to maintain steady RPMs at consistent speeds, enabling the transmission to lock into higher gears and operate at optimal efficiency, which is why the highway rating climbs to 21 MPG.

Understanding this split is crucial for owners who spend significant time in either environment. Those with highway-heavy commutes or regular long-distance hauling will see fuel economy closer to 21 MPG, while contractors and delivery operators navigating city streets will experience economy closer to the 17 MPG rating. Most owners will find their real-world consumption falls somewhere between these two figures, trending toward the 19 MPG combined estimate when driving includes a healthy mix of both environments.

Annual Fuel Cost

Based on EPA estimates, calculating annual fuel costs provides practical insight into the ownership expense of the 2024 F-350. Using the combined 19 MPG rating, 15,000 annual miles, and a diesel fuel price of $3.50 per gallon, the calculation is straightforward:

Annual Fuel Cost Calculation:

15,000 miles ÷ 19 MPG = 789.47 gallons per year
789.47 gallons × $3.50 per gallon = $2,763.16 annual fuel cost

This means the average F-350 owner can expect to spend approximately $2,763 per year on diesel fuel at current price points. It’s important to note that actual costs will vary based on local fuel prices, which fluctuate seasonally and geographically. Owners in regions with higher diesel prices will pay more, while those in areas with lower prices may see annual costs dip below this estimate. Conversely, drivers who exceed 15,000 annual miles or achieve lower real-world MPG will face higher fuel expenses.

Real-World MPG Expectations

EPA ratings provide a standardized baseline, but real-world driving typically deviates from laboratory testing conditions. Most F-350 owners report fuel economy ranging from 16 to 22 MPG depending on driving habits, cargo load, and maintenance condition. Several factors influence actual MPG: a fully loaded truck carrying material or towing a trailer will see economy drop toward the lower end of the range, while highway cruising with minimal load may approach or exceed the 21 MPG highway rating.

Maximizing real-world efficiency starts with proper maintenance. Keeping the diesel engine well-tuned, using the manufacturer-recommended oil viscosity, and maintaining proper tire pressure all contribute to optimal fuel consumption. Aggressive acceleration, excessive idling, and carrying unnecessary weight in the truck bed all diminish MPG. Many experienced F-350 owners find that steady, moderate acceleration and maintaining consistent highway speeds yields the best fuel economy results.

How It Compares

In the heavy-duty diesel truck segment, the 2024 F-350’s 19 MPG combined rating is competitive. The 2024 Chevrolet Silverado 3500HD with its 6.6L Duramax diesel achieves approximately 18 MPG combined, while the 2024 Ram 3500 with the 6.7L Cummins diesel typically delivers around 19 MPG combined as well. The F-350 holds its ground among peers, offering comparable efficiency while delivering the robust towing and payload capacity that defines the super-duty class. These small differences in MPG ratings matter more in real-world driving scenarios, where individual truck configuration, driving patterns, and maintenance habits create meaningful variations.

Tips to Maximize Efficiency

• Maintain Proper Tire Pressure: Under-inflated tires increase rolling resistance and reduce MPG. Check tire pressure monthly and maintain manufacturer specifications found on the driver’s door jamb.
• Use Quality Diesel Fuel: Premium diesel fuel contains detergents that keep fuel injectors clean, maintaining optimal combustion efficiency and fuel economy.
• Minimize Idle Time: Modern diesel engines use fuel while idling; shut off the engine during extended waits rather than letting it run unnecessarily.
• Reduce Payload Weight: Remove unnecessary items from the truck bed. Every 100 pounds of extra weight reduces fuel economy, so haul only what you need.
• Plan Routes Efficiently: Combining trips and avoiding congested routes reduces overall fuel consumption by minimizing stop-and-go driving.

Frequently Asked Questions

Q: Is 19 MPG good for a super-duty diesel truck?
A: Yes, 19 MPG combined is respectable for a heavy-duty truck in the F-350’s class. These vehicles prioritize towing capacity and payload over fuel economy, making 19 MPG a solid achievement for a truck capable of handling demanding work.

Q: Will my F-350 achieve better MPG on the highway?
A: Yes, the EPA highway rating of 21 MPG represents the best fuel economy you’ll achieve. Highway driving at steady speeds allows the diesel engine and transmission to operate at peak efficiency, making extended highway trips your most fuel-efficient driving scenarios.

Q: How much diesel fuel does the F-350 tank hold?
A: The 2024 F-350 Crew Cab features a fuel tank capacity of approximately 68 gallons. This substantial tank combined with 19 MPG fuel economy provides an estimated driving range of roughly 1,292 miles per tank under ideal conditions.

The 2024 Ford F-350 6.7L Power Stroke Diesel Crew Cab 6.75ft represents a balanced approach to heavy-duty truck ownership, delivering the power and capacity serious work demands while maintaining competitive fuel economy in its class. Understanding the EPA ratings, calculating annual costs, and implementing efficiency-focused driving habits will help maximize the value of this capable truck.
