22 MPG combined is a practical compromise for drivers who need the capability of a 2019 Ford F150 4WD with the base payload package and LT tires, powered by the 3.0L 6-cylinder diesel engine. This isn’t a truck for casual trips; it’s a workhorse chosen for its towing, payload capacity, and relative efficiency in a segment not known for sipping fuel.

City and highway performance

The EPA estimates the 2019 F150 4WD with this diesel powertrain achieves 20 MPG in the city and 25 MPG on the highway. These figures reflect the engine’s ability to deliver torque at low RPMs, which is crucial for hauling loads and navigating stop-and-go traffic. The 10-speed automatic transmission (S10) plays an important role optimizing fuel use across diverse driving scenarios through carefully calibrated gear ratios. Highway fuel economy benefits from the engine’s relaxed cruising speed and the aerodynamic properties of the F150’s cab and body design. However, that 25 MPG will quickly drop if you’re consistently running at high speeds or towing a substantial load.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2019 Ford F150 configuration at $2,550. This figure is based on driving 15,000 miles per year, assuming a national average fuel price. Individual costs will vary depending on driving habits and local fuel prices, however, this number provides a standardized benchmark for comparison. A driver covering significantly more miles may spend thousands more each year at the pump. Even small variations in fuel costs can cause changes in the bottom line.

Real-world expectations

While the EPA provides a standardized testing framework, real-world fuel economy will change based on driving habits, load, and terrain. Expect lower MPG when frequently towing, carrying heavy payloads, or driving in hilly areas. Aggressive acceleration and high speeds will also negatively impact fuel efficiency. However, adopting a smooth driving style, maintaining proper tire inflation, and performing regular maintenance can help achieve figures closer to the EPA estimates, and perhaps even exceed them. Drivers who consistently monitor and adjust for driving habits will achieve the best fuel economy.

How it compares

The 2019 F150 4WD 3.0L diesel’s 22 MPG combined compares favorably to other full-size trucks with similar capabilities. For example, the gasoline-powered Chevrolet Silverado 1500 4WD with the 5.3L V8 typically achieves around 17-18 MPG combined, and the Ram 1500 4WD with its 5.7L Hemi V8 also falls in the same range. The Nissan Titan XD, known for its heavier-duty build, is even less fuel-efficient, often landing in the 14-16 MPG range. While other, smaller trucks may achieve better fuel economy all Ford fuel economy data, they generally lack the F150’s towing and payload capacity. See F150 MPG across all years for even more vehicle data. This MPG comparison is important for buyers weighing the need for truck capabilities against the long-term cost of fuel.

Tips to maximize efficiency

Gentle acceleration and braking significantly improve fuel consumption. Avoid sudden bursts of speed and anticipate traffic conditions to minimize hard braking. This smooth driving style allows the engine’s torque to work efficiently, especially at lower speeds.

Maintaining proper tire inflation is critical. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate to the recommended pressure printed on the door placard, particularly when hauling significant loads.

Reduce unnecessary weight. Carrying extra tools, equipment, or cargo adds to the vehicle’s load, decreasing fuel economy. Remove any items you don’t need to improve MPG, as every pound counts.

Minimize idling time. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, turn off the engine. Modern diesel engines are designed to restart quickly and efficiently, minimizing fuel waste and strain on the starting system.

Service the diesel particulate filter on schedule. When the system is working optimally, this will reduce backpressure, which translates to more efficient operation of the engine itself. When this system fails through lack of service, fuel economy can suffer dramatically.
