Ford Super Duty Fuel Efficiency and Tank Capacity: A Comprehensive Guide

The Ford Super Duty line of heavy-duty pickup trucks is renowned for its impressive towing and hauling capabilities. However, fuel efficiency and range are also important considerations for many truck owners. In this comprehensive guide, we’ll explore the fuel tank capacities, fuel economy ratings, and real-world efficiency across different Super Duty generations and variants.

Understanding Fuel Efficiency in Heavy-Duty Trucks

Before diving into the specifics, it’s important to note that official EPA fuel economy ratings are not required for heavy-duty trucks like the Super Duty. This means that direct comparisons can be challenging, as manufacturers are not obligated to test and report fuel economy figures in a standardized way. However, we can still gain valuable insights from a combination of manufacturer-provided data, independent testing, and real-world owner experiences.

Fuel Tank Capacity Across Super Duty Generations

The fuel tank capacity of Ford Super Duty trucks has evolved over the years, generally increasing to provide greater range. Here’s an overview of fuel tank capacities across generations:

First Generation (1999-2007)

  • Standard tank: 29 gallons (109.8 liters)
  • Optional tank: 38 gallons (143.8 liters)

Second Generation (2008-2010)

  • Standard tank: 30.5 gallons (115.5 liters)
  • Optional tank: 38 gallons (143.8 liters)

Third Generation (2011-2016)

  • Standard tank: 26 gallons (98.4 liters) – midship tank
  • Optional tank: 37.5 gallons (142 liters) – rear tank

Fourth Generation (2017-2022)

  • Standard tank: 34 gallons (128.7 liters) – Crew Cab, 6.75′ bed
  • Optional tank: 48 gallons (181.7 liters) – Crew Cab, 8′ bed

Fifth Generation (2023-present)

  • Standard tank: 34 gallons (128.7 liters)
  • Optional tank: 48 gallons (181.7 liters)

It’s worth noting that tank capacity can vary depending on cab configuration, bed length, and drivetrain (4×2 vs 4×4).

Fuel Efficiency Across Super Duty Variants

While official EPA ratings are not available, we can examine fuel efficiency estimates and real-world reports for different Super Duty engine options:

6.2L V8 Gasoline Engine

The 6.2L V8 gasoline engine has been a staple of the Super Duty lineup for many years. In the latest generation, it offers 385 horsepower and 430 lb-ft of torque. Fuel efficiency estimates for this engine typically range from 11-15 mpg (14.7-21.2 L/100km) in mixed driving conditions.

7.3L V8 Gasoline Engine

Introduced in 2020, the 7.3L V8 “Godzilla” engine provides 430 horsepower and 475 lb-ft of torque. Despite its larger displacement, this engine can achieve similar fuel efficiency to the 6.2L V8, with owners reporting 12-16 mpg (14.7-19.6 L/100km) in real-world driving.

6.7L Power Stroke V8 Diesel Engine

The 6.7L Power Stroke diesel engine is known for its impressive torque and towing capabilities. In its latest iteration, it produces 475 horsepower and a massive 1,050 lb-ft of torque. Diesel engines typically offer better fuel efficiency, with owners reporting 14-18 mpg (13.1-16.8 L/100km) in mixed driving conditions.

Note: These figures are estimates based on real-world owner reports and may vary depending on driving conditions, load, and individual truck configuration.

Factors Affecting Fuel Efficiency in Super Duty Trucks

Several factors can significantly impact the fuel efficiency of Ford Super Duty trucks:

1. Payload and Towing

Heavy-duty trucks like the Super Duty are designed for towing and hauling heavy loads. When operating at or near maximum payload or towing capacity, fuel efficiency can decrease by 30-50% compared to unloaded driving.

2. Driving Conditions

Highway driving typically yields better fuel economy than city driving due to consistent speeds and less frequent stops. Additionally, factors like terrain (hilly vs. flat) and weather conditions can impact efficiency.

3. Maintenance

Proper maintenance, including regular oil changes, air filter replacements, and tire pressure checks, can help maintain optimal fuel efficiency.

4. Driving Habits

Aggressive acceleration, excessive idling, and high-speed driving can all negatively impact fuel economy. Adopting more efficient driving habits can lead to noticeable improvements in fuel consumption.

Maximizing Fuel Efficiency in Your Super Duty

While heavy-duty trucks are not primarily designed for fuel efficiency, there are several strategies Super Duty owners can employ to maximize their fuel economy:

1. Use the Right Fuel

For gasoline engines, use the recommended octane rating. For diesel engines, choose high-quality diesel fuel to ensure optimal performance and efficiency.

2. Maintain Proper Tire Pressure

Underinflated tires can increase rolling resistance, leading to decreased fuel efficiency. Regularly check and maintain proper tire pressure according to the manufacturer’s recommendations.

3. Reduce Unnecessary Weight

Remove any unnecessary items from your truck to reduce weight and improve fuel economy when not towing or hauling.

4. Use Cruise Control

On long highway drives, using cruise control can help maintain a consistent speed and improve overall fuel efficiency.

5. Plan Your Routes

Avoid traffic congestion and plan routes with fewer stops to maximize fuel economy during your trips.

Real-World Fuel Efficiency Examples

To provide a more practical perspective on Super Duty fuel efficiency, let’s look at some real-world examples reported by owners:

2021 F-250 with 6.7L Power Stroke Diesel

  • Unloaded highway driving: 18-20 mpg (11.8-13.1 L/100km)
  • Towing 10,000 lbs trailer: 10-12 mpg (19.6-23.5 L/100km)

2022 F-350 with 7.3L V8 Gas Engine

  • Mixed city/highway driving: 13-15 mpg (15.7-18.1 L/100km)
  • Towing 8,000 lbs boat: 8-10 mpg (23.5-29.4 L/100km)

2020 F-450 with 6.7L Power Stroke Diesel

  • Unloaded highway driving: 16-18 mpg (13.1-14.7 L/100km)
  • Towing 20,000 lbs fifth-wheel: 7-9 mpg (26.1-33.6 L/100km)

These examples highlight the significant impact that load and driving conditions can have on real-world fuel efficiency.

Future of Fuel Efficiency in Super Duty Trucks

As environmental concerns and fuel costs continue to be important factors for many truck owners, Ford is actively working on improving the fuel efficiency of its Super Duty lineup. Some potential developments to watch for include:

1. Hybrid Powertrains

While not yet available in the Super Duty line, hybrid technology could potentially be adapted from the F-150 PowerBoost hybrid to provide improved fuel efficiency in heavy-duty applications.

2. Advanced Aerodynamics

Future Super Duty models may incorporate more advanced aerodynamic features to reduce drag and improve fuel economy, especially during highway driving.

3. Lightweight Materials

The use of lightweight materials, such as high-strength steel and aluminum alloys, could help reduce overall vehicle weight and improve fuel efficiency without compromising capability.

4. Electric Options

While full electrification of heavy-duty trucks presents significant challenges, Ford is investing heavily in electric vehicle technology. It’s possible that we may see electric or plug-in hybrid Super Duty variants in the future.

Conclusion

The Ford Super Duty lineup offers impressive capabilities and a range of powertrain options to suit various needs. While fuel efficiency may not be the primary focus for many heavy-duty truck buyers, it remains an important consideration for overall operating costs and environmental impact.

Whether you’re using your Super Duty for work, play, or both, being mindful of fuel efficiency can help you get the most out of your truck while minimizing fuel costs and environmental impact. With proper maintenance, smart driving habits, and an understanding of your truck’s capabilities, you can enjoy the power and versatility of the Ford Super Duty while optimizing its fuel efficiency.
