17 MPG combined is the reality for anyone considering a 2017 Ford Expedition 4WD with the 3.5L EcoBoost V6. Nobody buys a truck-based, full-size SUV like the Expedition for its Prius-rivaling efficiency. This vehicle is about capability: hauling families, towing boats, and tackling snowy roads with confidence. The fuel economy, while not exactly celebrated, is simply what you pay for the utility it offers.
City and highway performance
The EPA estimates 15 MPG in the city and 20 MPG on the highway for this particular Expedition configuration. Real-world urban driving, with its stop-and-go traffic and frequent idling, will likely yield numbers below that city rating. Conversely, a long highway trip at a steady speed, without aggressive acceleration, could potentially get you closer to, or even slightly above, the 20 MPG mark depending on several factors such as load and roof rack use. The 6-speed automatic transmission is generally smooth and predictable, but it can sometimes hesitate to downshift for quick bursts of acceleration, a common trait in vehicles of this size attempting to maximize fuel economy.
Annual fuel cost
The EPA estimates an annual fuel cost of $2,600 for the 2017 Ford Expedition 4WD 3.5L. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using the national average fuel price when the EPA testing was performed. Keep in mind that fluctuating gas prices will directly impact this annual cost. If gas prices rise significantly, expect to pay even more at the pump. Conversely, lower gas prices will provide some relief. This figure also depends on the driver’s habits and local traffic conditions.
Real-world expectations
Expectations matter. If you’re coming from a compact sedan, the Expedition’s fuel consumption will be a shock. Those who buy this vehicle often prioritize space, towing capacity, and passenger comfort over saving on gas. Many buyers are already accustomed to the fuel demands of large SUVs or trucks. While the EPA estimates provide a benchmark, individual driving habits, terrain, and weather conditions will have a noticeable impact on the numbers you see on your dashboard. Regularly towing heavy loads, for example, will drastically decrease your MPG.
How it compares
The 2017 Expedition’s fuel economy falls roughly in line with its primary competitors. The Chevrolet Tahoe 4WD with the 5.3L V8, for example, is rated at 16 MPG combined, putting it in the same ballpark. The Nissan Armada, another full-size SUV, achieves around 15 MPG combined in 4WD guise. The Toyota Sequoia, with its 5.7L V8, also hovers around the 15 MPG mark. These comparisons matter because buyers in this segment are often cross-shopping these vehicles. The differences of 1-2 MPG can translate into hundreds of dollars in annual fuel costs, influencing the final decision.

Tips to maximize efficiency
Monitor your driving habits. The Expedition’s EcoBoost engine is responsive, but aggressive acceleration and hard braking will severely impact fuel economy. Focus on smooth, deliberate inputs and anticipate traffic flow to minimize unnecessary stops.
Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and maintain the recommended PSI as indicated on the doorjamb sticker.
Reduce unnecessary weight. Hauling around extra cargo adds to the vehicle’s overall weight, impacting fuel economy. Remove any items you don’t need from the vehicle, especially when not towing or carrying a full load of passengers.
Consider using cruise control on the highway. Maintaining a consistent speed can help optimize fuel efficiency on long trips. Avoid excessively speeding and fluctuating speeds, which wastes gas.
Keep up with scheduled maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements, to ensure optimal performance.
