21 MPG combined won’t win any hypermiling awards, but for a 2018 Ford F150 4×4 equipped with the 2.7L EcoBoost V6 and a GVWR (Gross Vehicle Weight Rating) over 6,799 lbs, it’s a reasonable balance between capability and saving gas. People buying this specific F150 configuration aren’t prioritizing Prius-level fuel efficiency. They need a truck that can handle demanding tasks, tow trailers, and navigate challenging terrain. The 2.7L EcoBoost, in this heavier-duty application, delivers acceptable fuel efficiency while providing the power required for real work.

City and highway performance

The EPA estimates for the 2018 F150 2.7L 4×4 (GVWR>6799 lbs) are 19 MPG in the city and 24 MPG on the highway. The difference between city and highway MPG is significant. Stop-and-go traffic and idling take a noticeable toll on fuel economy in a truck of this size. The 2.7L EcoBoost is equipped with auto start-stop, which helps reduce fuel consumption during city driving, but its effectiveness depends on driving habits and traffic conditions. On the highway, the F150’s 10-speed automatic transmission (S10) allows the engine to operate at lower RPMs, improving fuel efficiency. However, maintaining higher speeds, especially when towing or hauling, will still impact fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2018 Ford F150 configuration at $2,100. This figure is based on driving 15,000 miles per year and national average fuel prices. Remember that this is an estimate, and your actual fuel costs may vary depending on your driving habits, fuel prices in your area, and how you use your truck. If you primarily drive in the city, tow frequently, or drive aggressively, your annual fuel costs will likely exceed $2,100. If you drive mainly on the highway and adopt fuel-efficient driving techniques, you may be able to lower your annual fuel expenses.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world MPG often differs. Many F150 owners report figures slightly below the combined 21 MPG. Tire size, aftermarket modifications (such as lift kits or larger tires), driving style, and the weight of cargo or trailers affect real-world fuel economy. Off-road driving, with its increased drag and lower speeds, will also significantly reduce fuel efficiency. Expect figures in the 17-22 MPG range in mixed driving conditions. Understanding these variables is important for managing expectations and planning fuel budgets.

How it compares

Compared to other full-size trucks, the 2018 Ford F150 2.7L 4×4 (GVWR>6799 lbs) holds its own in terms of fuel economy. A comparable 2018 Chevrolet Silverado 1500 4×4 with the 5.3L V8 is rated at 19 MPG combined. The RAM 1500 4×4 with the 5.7L Hemi V8 from the same year achieves a similar 17 MPG combined. These differences add up over time. The F150’s EcoBoost engine’s combination of turbocharging and direct injection helps with its efficiency, but it competes with V8 engines that offer a different character and sound. For buyers concerned about fuel costs, researching all Ford fuel economy data and understanding the trade-offs between different engines and configurations is essential.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 2.7L EcoBoost delivers plenty of torque, but using that power frequently will quickly deplete your fuel tank. Smooth, gradual acceleration and anticipation of traffic conditions will significantly improve fuel economy.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate your tires to the manufacturer’s recommended pressure, which can be found on the sticker inside the driver’s side door jamb.

Reduce unnecessary weight. Carrying extra weight in the bed of your truck or the cab puts additional strain on the engine, decreasing fuel economy. Remove any unnecessary items and only carry what you need.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel consumption. Using cruise control on long highway drives can prevent unintentional acceleration and improve fuel efficiency.

Consider using 4×4 only when necessary. Driving in four-wheel drive increases fuel consumption. Only engage 4×4 when you need the extra traction, such as in snowy or icy conditions, or when driving off-road. Switching back to two-wheel drive when appropriate will save fuel.
