20 MPG combined isn’t going to set any fuel-sipping records, but for the 2021 Ford F150 Pickup 4WD with the 3.5L EcoBoost V6, it’s a reasonable compromise for a truck that tows, hauls, and occasionally tackles off-road trails. This isn’t a truck for hypermilers; it’s a tool, a workhorse, and a lifestyle enabler, and its fuel consumption reflects that.

City and highway performance

The EPA estimates the 2021 F150 4WD 3.5L EcoBoost at 18 MPG in the city and 23 MPG on the highway. These figures reflect the engine’s tuning and capability. The EcoBoost’s turbochargers provide ample low-end torque for confident acceleration around town, which inherently impacts city fuel economy. Highway MPG fares better, thanks largely to the 10-speed automatic transmission which allows the engine to run at relatively low RPMs when cruising. However, factors like higher speeds, wind resistance (a pickup isn’t exactly aerodynamic), and the rolling resistance of all-terrain tires (if equipped) will push that number down. Achieving the EPA’s 23 MPG requires a disciplined right foot and favorable conditions.

Annual fuel cost

The EPA estimates that the annual fuel cost for this specific configuration of the 2021 Ford F150 is $2,200. This is calculated based on driving 15,000 miles per year with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and fluctuating fuel prices in your area. Think of it as a benchmark helpful for comparisons, but don’t take it as gospel.

Real-world expectations

The EPA provides a standardized testing environment, but real-world MPG often differs. F150 owners who frequently tow or haul heavy loads will likely see their fuel economy dip below the EPA estimates, sometimes significantly. Aggressive driving habits, constant stop-and-go traffic, and aftermarket modifications (such as larger tires or lift kits) will also negatively affect fuel consumption. However, drivers who primarily use their F150 for commuting on relatively flat roads might exceed the EPA’s highway figure. A realistic expectation for most owners is to see MPG figures within a range of 17-22 MPG combined, acknowledging that it can shift above or below this depending on usage patterns. If you’re curious, you can look at F150 MPG across all years.

How it compares

The F150’s fuel economy is competitive within its segment, but comparisons always require nuance. For example, the Chevrolet Silverado 1500 4WD with the 5.3L V8 is EPA-rated at 17 MPG combined. That’s lower than the F150, but some buyers might prioritize the V8’s sound and traditional feel over potential fuel savings. The Ram 1500 4WD with the 5.7L Hemi V8 (without eTorque) is rated at approximately 19 MPG combined, placing it slightly below the F150. The Toyota Tundra, known for its reliability but not its fuel efficiency, can barely achieve 15 MPG combined in its 4WD V8 configuration. These comparisons matter to the F150 buyer because they’re often weighing capability, brand loyalty, and resale value along with fuel costs. It’s a multifaceted decision influenced by priorities that extend beyond pure MPG numbers, though it remains an important factor.

Tips to maximize efficiency

One simple way to improve fuel economy in your 2021 Ford F150 is to drive smoothly. Avoid aggressive acceleration and hard braking. The EcoBoost engine benefits significantly from a gentle touch on the throttle, allowing the turbochargers to spool up gradually and deliver power without excessive fuel consumption. Anticipate traffic flow and maintain a consistent speed whenever possible.

Regular maintenance is also important. Ensure your tires are properly inflated. Low tire pressure increases rolling resistance, which directly impacts fuel economy. Keep up with scheduled maintenance, including oil changes and air filter replacements, to ensure your engine is running efficiently. A well-maintained engine will always perform better than one that’s neglected.

Minimize idling. Modern engines don’t need to warm up for extended periods, and idling wastes fuel. If you’re going to be stopped for more than a minute or two, turn off the engine. This simple practice can add up to noticeable fuel savings over time, especially for drivers who spend a lot of time in stop-and-go traffic.

Consider the load you’re carrying. Unnecessary weight reduces fuel economy. Remove any items from the bed of your truck that you don’t need. And, if you have a roof rack or cargo carrier, consider removing it when not in use. These accessories increase aerodynamic drag, which negatively impacts fuel efficiency, especially at higher speeds.
