21 MPG combined might not sound impressive at first glance, but it’s a respectable figure for the 2017 Ford F-150 SuperCrew with the 5.5-foot bed and the 3.5L EcoBoost V6. This configuration is for buyers who need strong capability for work or recreation, and who also prioritize passenger comfort and space more than ultimate fuel saving. This isn’t a truck for hypermilers; it’s for contractors, families hauling campers, and anyone who demands versatility and doesn’t mind paying a bit more at the pump.

City and highway performance

The EPA estimates for the 2017 F-150 SuperCrew 5.5ft with the 3.5L EcoBoost and 6-speed automatic are 18 MPG in the city and 25 MPG on the highway. The city figure reflects the reality of stop-and-go traffic and the engine working harder to move the truck’s mass. Even with features like auto start-stop designed to save fuel at idle, the city MPG will always be the low point. The 25 MPG highway rating is more attainable, especially during steady-state cruising. The EcoBoost engine shines on the open road, delivering decent fuel economy while still providing ample power for passing or pulling.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2017 Ford F-150 configuration at exactly $2,500. This calculation is based on driving 15,000 miles per year, using a mix of city and highway driving, and assuming the national average fuel price. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and where you live, fuel prices can vary significantly by state or even locally. If you primarily drive in the city or frequently tow heavy loads, expect to exceed the $2,500 estimate.

If you mostly do highway miles and drive conservatively, you might spend less. You can explore all Ford fuel economy data on FuelEconomyHub.com.

Real-world expectations

EPA figures provide a baseline, but real-world MPG for the 2017 F-150 SuperCrew 5.5ft 3.5L EcoBoost will often differ. Load weight, driving style, and environmental factors all play a role. Aggressive acceleration, frequent braking, and carrying heavy cargo will decrease fuel economy. Headwinds and hilly terrain can also have a noticeable impact. Many owners average around 19-22 MPG in mixed driving, which aligns reasonably well with the EPA’s combined rating.

It’s critical to be realistic about the potential for lower MPG if your driving habits are less than fuel-efficient. Tire pressure also makes a significant difference, so regularly check and maintain the recommended pressure for optimal fuel economy.

How it compares

The 2017 F-150 with the EcoBoost engine holds its own relatively well compared to other trucks in its class. A comparably equipped 2017 Chevrolet Silverado 1500 with the 5.3L V8 generally achieves around 16 MPG city and 22 MPG highway. A 2017 Toyota Tundra with the 5.7L V8 typically lags even further behind, averaging around 13 MPG city and 18 MPG highway. The EcoBoost’s advantage comes from its turbocharged design, which allows it to deliver V8-like power with better fuel efficiency when not under heavy load. Someone considering an F-150 appreciates this trade-off, accepting slightly higher fuel costs than a midsize truck for the added capability and space.

Tips to maximize efficiency

The F-150 EcoBoost responds well to a smooth and deliberate driving style. Avoid sudden acceleration and braking, as these actions consume significantly more fuel. Anticipate traffic flow and maintain a consistent speed whenever possible. This not only improves fuel economy, but also enhances driving comfort, especially on long highway trips.

Towing has a drastic impact on fuel economy. When hauling trailers or other heavy loads, reduce your speed and increase following distance. Use the Tow/Haul mode judiciously; it changes the transmission’s shift points to optimize power output, but it also causes the engine to rev higher and burn more fuel. Only engage Tow/Haul when actually needed.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel efficiency. Regularly check your tire pressure and inflate them to the manufacturer’s recommended level, which can be found on the doorjamb or in the owner’s manual.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Modern vehicles like the F-150 EcoBoost have systems designed to restart quickly and efficiently, so you won’t experience any significant delay. Excessive idling wastes fuel and contributes to unnecessary emissions, especially in congested areas.
