22 MPG combined is a respectable number for a 2018 Ford F150 Pickup 4WD with the 3.0L diesel engine. This isn’t a Prius, nor is it trying to be. The F150 with this powertrain appeals to buyers who need real truck capability, towing, payload, all-weather traction, but who also value fuel efficiency more than V8 power. This configuration finds a sweet spot, offering a blend of utility and economy that’s hard to ignore for the right customer.

City and highway performance

The EPA estimates 20 MPG in the city and 25 MPG on the highway for this specific F150 configuration. The city figure reflects the stop and go driving and idling inherent to urban environments, situations where a larger-displacement engine would typically suffer significantly. The diesel’s inherent efficiency and modern fuel injection help mitigate these losses. Out on the open road, the 25 MPG highway rating shows the engine comfortably cruising at higher speeds, using its torque and the 10-speed automatic transmission to optimize fuel consumption. These numbers aren’t just theoretical; they represent the potential for meaningful savings over the lifetime of the vehicle, especially for owners who rack up significant mileage.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,550 for this F150 model. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark, but your actual fuel costs could vary depending on your driving habits, fuel prices in your area, and the type of driving you do. Commuters who spend a lot of time in heavy traffic will likely see higher costs, while those who primarily use the truck for long highway trips might find themselves spending less.

Real-world expectations

While the EPA numbers provide a solid baseline, real-world fuel economy can vary. Factors like driving style, load weight, tire pressure, and even weather conditions can all influence your MPG. Aggressive acceleration and hard braking will certainly hurt fuel economy, as will towing heavy loads. Owners who prioritize efficiency will likely see numbers close to the EPA estimates, while those who frequently engage in demanding tasks should expect a dip. Regular maintenance, including timely oil changes and air filter replacements, is also crucial for maintaining optimal fuel efficiency.

How it compares

Compared to other full-size trucks, the 2018 F150 3.0L diesel holds its own. A similarly equipped Chevrolet Silverado 1500 with the 3.0L Duramax diesel achieves roughly the same numbers, around 23 MPG combined. The Ram 1500 EcoDiesel also competes in this segment, with figures typically around 24 MPG combined. Keep in mind that these figures can vary based on specific trim levels and options. The critical point is that the F150 doesn’t lag behind its main competitors in fuel economy; instead, it offers a comparable level of efficiency for buyers seeking a diesel-powered full-size truck. For those not needing diesel power, gasoline V6 and V8 F150 models offer less impressive fuel economy. See F150 MPG across all years for more information.

Tips to maximize efficiency

Gentle acceleration and smooth braking are important. Avoid aggressive driving habits, as they can significantly reduce fuel economy. Anticipating traffic flow and maintaining a steady speed is key.

Proper tire inflation is often overlooked. Ensure your tires are inflated to the recommended pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, leading to lower fuel efficiency. Regularly check and adjust tire pressure, especially with temperature changes.

Reduce excess weight whenever possible. Carrying unnecessary cargo adds strain to the engine and reduces fuel economy. Remove any items from the bed or cabin that you don’t need on a regular basis.

Minimize idling time. Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute or two, turn off the engine. Restarting a modern engine consumes far less fuel than prolonged idling.

Consider disabling four-wheel drive when it isn’t needed. Driving in 4WD on dry pavement increases friction and reduces fuel economy. Only engage 4WD when you need the extra traction, such as in snow, mud, or off-road conditions. The system adds weight and drivetrain friction, so keeping the vehicle in 2WD will help efficiency.
