The 2018 Ford F-150 with the 5.0L V8, four-wheel drive, and a heavy-duty GVWR exceeding 7599 lbs has an EPA fuel economy rating of 17 MPG combined. This truck prioritizes capability over outright efficiency, unlike a Prius. Buyers of these specific F-150s need the reliable powertrain and towing capacity and accept the fuel consumption trade-off. This truck isn’t for grocery runs; it’s built for work, heavy hauling, and often farm or ranch duty. If you need the muscle, you accept the mileage.

City and highway performance

The EPA breaks down the F-150’s fuel economy further, showing 15 MPG in the city and 19 MPG on the highway. The lower city figure reflects the stop-and-go traffic and idling that penalize larger displacement engines. The highway number, while still not stellar, showcases the engine’s efficiency at consistent speeds, helped by the 10-speed automatic transmission (S10) which optimizes engine RPM. Lower trim levels of this generation truck can perform significantly better, so keep that in mind when shopping the used market. Consider the F150 MPG across all years to understand the range of choices. This particular setup, however, is about raw power and payload capacity, not sipping fuel.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,600 for this particular 2018 Ford F-150 configuration. This figure is based on driving 15,000 miles per year, using a national average fuel price. Individual spending varies dramatically. Someone who primarily uses the truck for short trips around town will likely exceed that $2,600 estimate, while someone who does mostly highway driving, and drives fewer miles, may spend less. Fuel prices also play a major role. Changes in the national average since 2018 impact the current accuracy of the estimate. It serves as a benchmark for comparison, but your real-world expenses will be determined by your specific driving habits and location.

Real-world expectations

EPA estimates offer a standardized comparison, but some drivers report real-world fuel economy often falls short. Hauling heavy loads, towing trailers, or driving in four-wheel drive will plummet the MPG. Aggressive driving habits, such as rapid acceleration and hard braking, will also negatively impact fuel consumption. However, a careful driver on a long highway trip might see figures closer to, or even slightly above, the EPA’s 19 MPG highway estimate. Keep in mind that this F-150 is also a FFV, meaning it can run on E85 fuel, which can reduce tailpipe emissions but will significantly decrease gas mileage.

How it compares

The 2018 F-150 5.0L 4WD’s fuel economy numbers stack up differently against various competitor configurations. A similarly equipped Chevrolet Silverado 1500 with the 5.3L V8 and four-wheel drive generally achieves near identical EPA figures, around 16 MPG combined. The Ram 1500 with the 5.7L Hemi and four-wheel drive often comes in slightly lower, closer to 15 MPG combined. The Toyota Tundra, known for its reliability but not its fuel efficiency, typically trails the F-150 with a combined MPG in the 13-15 range for its V8 models. For buyers who prioritize fuel economy, all Ford fuel economy data showcases other, more efficient F-150 configurations, like the 2.7L EcoBoost or 3.5L EcoBoost models, which deliver significantly better MPG at a slight reduction in maximum towing capacity.

Tips to maximize efficiency

Monitor your tire pressure rigorously. Underinflated tires create more rolling resistance, directly impacting fuel economy. Check your tires monthly and inflate them to the pressure specified on the door jamb sticker, not the maximum pressure listed on the tire itself, as this can overinflate them.

Drive smoothly and avoid aggressive acceleration. The 5.0L V8 is powerful, but every time you stomp on the gas, you’re burning extra fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Minimize idling. Modern engines don’t need to “warm up” for extended periods. If you’re going to be stopped for more than a minute or two, turn off the engine. Excessive idling consumes fuel without covering any distance.

Reduce weight. Carrying unnecessary cargo in the bed of the truck reduces fuel economy. Clean out any tools, equipment, or other items that you don’t need on a regular basis. Less weight translates directly to better gas mileage.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy, especially on long trips. However, avoid using cruise control in hilly terrain, as the transmission may downshift frequently, negating any potential fuel savings.
