25 MPG combined is respectable for the 2018 Ford F150 2WD with the 3.0L Power Stroke diesel. While it won’t rival a midsize sedan, this fuel economy is significant for a full-size pickup truck capable of strong hauling and towing. This particular configuration appeals to buyers who need the truck’s utility but prioritize fuel savings, often those who frequently drive long distances or work in fuel-sensitive industries. They understand the trade-off between raw power and efficiency and find this diesel option strikes a balance.

City and highway performance

The F150 diesel’s individual city and highway numbers are noteworthy. The EPA estimates 22 MPG in the city, which is surprisingly good for a vehicle of this size constantly dealing with stop-and-go traffic. On the highway, it truly shines with 30 MPG. This highway efficiency is a major selling point for contractors who regularly travel between job sites, or for anyone who uses their F150 for long road trips. Many owners opt for the diesel specifically because of its long-range capability on the open road, minimizing fuel stops on extended drives.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for this F150 configuration is $2,250. This figure is based on driving 15,000 miles per year, using national average fuel prices. Keep in mind that your own fuel costs may vary, depending on how much you drive, where you drive, and your driving style. Fluctuations in diesel fuel prices will also affect this annual cost. Therefore, $2,250 is simply an estimate to allow comparison shopping for different vehicles. It’s a standardized figure used to level the playing field and provide a baseline expectation of what you’ll spend each year on fuel.

Real-world expectations

While EPA estimates provide a useful benchmark, real-world MPG often varies. Factors like driving habits, load weight, tire pressure, and even weather conditions can impact fuel economy. Owners who frequently tow heavy loads or drive aggressively will likely see lower MPG than the EPA estimates.

Conversely, drivers who prioritize smooth acceleration, maintain proper tire inflation, and avoid unnecessary idling may even exceed the EPA numbers. The overall condition of the vehicle, including regular maintenance and timely filter replacements, also plays a significant role in achieving optimal fuel economy.

How it compares

When considering fuel efficiency, it is important to see how the F150 diesel stacks up against the competition. The Chevy Silverado 1500 with its available 3.0L Duramax diesel engine achieves similar numbers. Both Ford and Chevy provide very similar MPG for their diesel half-tons. Ram offers the 1500 EcoDiesel, which can deliver comparable numbers, though real-world MPG numbers sometimes vary based on specific driving conditions. For perspective, gasoline-powered full-size trucks, even with smaller displacement turbocharged engines, typically struggle to reach 20 MPG combined, making the diesel’s advantage clear. You can compare F150 MPG across all years to see how this specific engine improved the truck’s fuel economy. Also, you can explore all Ford fuel economy data for other fuel-efficient models in their lineup.

The buyer choosing this diesel F150 is making a conscious decision to prioritize fuel economy over the higher horsepower and lower initial cost of the gasoline powered variants.

Tips to maximize efficiency

Gentle acceleration and consistent speed are key to maximizing fuel economy in the F150 diesel. Avoid sudden bursts of speed and try to maintain a steady pace, especially on the highway. The Power Stroke diesel delivers its torque relatively low in the RPM range, so there’s no need to rev the engine excessively.

Regular maintenance is important for optimal fuel efficiency. Ensure your F150 receives routine oil changes, air filter replacements, and tire rotations per the manufacturer’s recommendations. A well-maintained engine runs more efficiently and burns fuel more effectively.

Tire pressure plays a critical role in fuel economy. Check your tire pressure regularly and inflate your tires to the recommended specifications listed on the doorjamb. Underinflated tires create more rolling resistance, which reduces fuel efficiency.

Minimize idling whenever possible. Idling consumes fuel and generates zero miles per gallon. If you anticipate being stationary for more than a minute, it’s generally more efficient to turn off the engine.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. However, be mindful of terrain changes and be prepared to adjust your speed manually when necessary in hilly areas.
