The 2021 Ford F150 4WD with the 5.0L V8 and flex-fuel capability gets 19 MPG combined. Buyers choose this truck for its capability, impressive towing capacity, and the unmistakable rumble of that V8 engine, not fuel efficiency. It’s a workhorse, a tool, and a statement, and its fuel consumption reflects that.

City and highway performance

The EPA estimates the 2021 Ford F150 4WD FFV 5.0L V8 gets 16 MPG in the city and 22 MPG on the highway. The city figure reflects the stop-and-go driving this truck often encounters when hauling materials, navigating construction sites, or running errands. The highway number improves, but it’s still modest due to the vehicle’s weight, aerodynamic profile, and the engine.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2021 Ford F150 to be $2,300. This is based on driving 15,000 miles per year, using the EPA’s combined MPG estimate, and factoring in national average fuel prices. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and how often you operate on E85.

Real-world expectations

Real-world fuel economy often differs from EPA estimates. Owners report that the 22 MPG highway figure is attainable under ideal conditions. This means steady speeds, minimal cargo, and flat terrain. However, towing, hauling heavy loads, aggressive acceleration, and winter driving conditions can lower the average MPG. Regularly using E85 fuel will also significantly reduce fuel economy.

How it compares

The 2021 F150 with the 5.0L V8 is roughly in the middle compared to its competitors. The Chevrolet Silverado 1500 4WD with the available 5.3L V8 achieves a similar 19 MPG combined. The Ram 1500 4WD with the 5.7L Hemi is around the same number. Ford’s 2.7L EcoBoost V6 in a 4×4 F150 increases fuel economy up to 22 MPG combined, though it doesn’t have the V8 sound and feel. For buyers prioritizing efficiency, diesel options like the now-discontinued Ram 1500 EcoDiesel offered significantly better MPG, closer to 26-28 MPG on the highway. Understanding its efficiency relative to competitors helps owners budget effectively. You can view F150 MPG across all years here.

Tips to maximize efficiency

Gentle acceleration and consistent speed help save gas. Avoid quick starts and hard braking, as this wastes fuel and puts strain on the truck. Anticipate traffic flow and maintain a steady speed whenever possible. This is important on the highway, where speeding reduces fuel economy due to increased air resistance.

Keep your tires properly inflated. Check your tire pressure regularly, at least once a month, and inflate them to the recommended pressure listed on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, which impacts fuel economy. A tire pressure gauge can save you money.

Reduce weight. The more weight you carry, the more fuel your truck uses. Remove unnecessary items from the bed and cab. Even a few hundred pounds can negatively impact fuel economy, especially in city driving.

Consider using cruise control on the highway to maintain a consistent speed, which can improve fuel economy. Avoid using it in hilly terrain, where the transmission may downshift frequently to maintain speed diminishing any benefits.

Regular maintenance is important. Make sure your truck receives regular maintenance including oil changes, air filter replacements, and spark plug replacements, according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently and improves fuel economy. Browse all Ford fuel economy data for potential alternatives.
