A combined fuel economy of 17 MPG for the 2018 Ford F150 5.0L 4WD (GVWR greater than 7599 lbs) isn’t going to win any awards, but let’s be honest: nobody buys this specific configuration of F150 for its stellar gas mileage. This truck is purchased to haul, to tow, to be a reliable workhorse, and to confidently handle challenging conditions. The fuel economy, while not great, is simply part of the cost of doing business.

City and highway performance

The EPA estimates that this particular F150 configuration achieves 15 MPG in city driving and 19 MPG on the highway. These numbers reflect the realities of a heavy, four-wheel-drive truck powered by a strong 5.0L V8 engine. Stop-and-go city driving takes a heavy toll, as the engine works hard to accelerate the truck’s mass from a standstill. On the highway, the fuel economy improves somewhat, but aerodynamic drag and rolling resistance still limit efficiency. The F150’s boxy shape presents a significant challenge to slipperiness through the air. It’s not a streamlined sports car, and doesn’t pretend to be.

Factors like tire pressure, cargo weight, and driving style will significantly impact the numbers you see in everyday driving.

Annual fuel cost

The EPA estimates the annual fuel cost for this 2018 Ford F150 5.0L 4WD (GVWR greater than 7599 lbs) at $2,600. This figure is based on driving 15,000 miles per year, using EPA’s fuel economy estimates, and assuming the national average fuel price.

This is a useful benchmark for comparing the running costs of different vehicles, but individual expenses will fluctuate based on fuel prices in your area and how aggressively you drive. If you tow frequently or drive primarily in heavy traffic, expect to spend more than this amount on fuel annually.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world fuel economy can vary significantly. Many owners of the 2018 Ford F150 5.0L 4WD report that achieving the EPA’s combined 17 MPG is challenging in everyday driving. Hauling heavy loads, navigating steep terrain, or engaging four-wheel drive will noticeably decrease fuel efficiency. Aggressive driving habits, such as rapid acceleration and hard braking, likewise diminish MPG. On the other hand, those who primarily use their truck for highway cruising and demonstrate smooth driving habits may occasionally exceed the EPA’s highway estimate.

How it compares

When cross-shopping, it’s important to compare the F150 5.0L 4WD to similarly capable trucks. A comparable 2018 Chevrolet Silverado 1500 with the 5.3L V8 and four-wheel drive achieves an EPA-estimated 17 MPG combined. Ram 1500 models of the same year with the 5.7L Hemi and 4WD come in around 15 MPG combined.

These figures highlight that the F150’s fuel economy is broadly in line with its competitors in the full-size truck segment, especially when equipped with a powerful V8 and four-wheel drive. For buyers prioritizing fuel economy above all else, the F150 equipped with the 2.7L EcoBoost engine (rated at 20 MPG combined) or the 3.5L EcoBoost (rated near 19 MPG combined, depending on configuration) may be a better option. You can also explore F150 MPG across all years to see how this truck stacks up against prior model years.

Tips to maximize efficiency

Proper tire inflation makes a difference, especially on a heavy truck like this one. Regularly check your tire pressure and inflate them to the manufacturer’s recommended level, typically found on a sticker inside the driver’s side door. Underinflated tires increase rolling resistance, leading to lower fuel economy and premature tire wear.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and excessively high speeds burn more fuel. Smooth and consistent driving maximizes efficiency. Think about anticipating traffic flow and maintaining a steady speed whenever possible.

Reduce unnecessary weight in the truck bed. Every extra pound requires more energy to accelerate and maintain speed. Remove any tools, equipment, or cargo that isn’t needed for the current journey. Minimizing the weight that this 5.0L engine needs to motivate is a straightforward technique to save fuel.

Consider driving in two-wheel drive when four-wheel drive isn’t necessary. Engaging four-wheel drive increases fuel consumption due to the added mechanical resistance. Use four-wheel drive only when encountering slippery conditions or when requiring maximum traction, otherwise keep it in two-wheel drive. Ford has all Ford fuel economy data available on Fuel Economy Hub and other helpful resources in the Ford Owner’s Manual.

Regular maintenance is critical for optimal fuel economy. Ensure that your engine is properly tuned, with clean air filters, fresh spark plugs, and the correct type of engine oil. A well-maintained engine operates more efficiently, resulting in better gas mileage.
