The EPA estimates 17 MPG combined for the 2015 Ford Expedition EL 2WD with the 3.5L EcoBoost engine, a number that needs context. This figure doesn’t tell you that nobody buys this extended-length Expedition expecting Prius-like efficiency. This is a vehicle designed for a very specific mission: comfortably and safely hauling up to eight passengers and their cargo, towing substantial loads, and doing it with the reliability Ford trucks are known for. Fuel economy is a consideration, of course, but capability and space are often more important.

City and highway performance

The 2015 Expedition EL 2WD earns an EPA-estimated 15 MPG in the city and 21 MPG on the highway. That spread highlights the impact of this vehicle’s weight (around 5,700 pounds) and relatively large frontal area. Stop-and-go city driving puts a significant strain on the 3.5L EcoBoost V6, as it works to overcome inertia repeatedly. The highway figure, however, is more representative of the engine operating at a steady state, using its turbochargers for efficient power delivery at cruising speeds.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,600 for the 2015 Ford Expedition EL 2WD. 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. It also assumes national average fuel prices. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and how often you fully use the Expedition EL’s capabilities for towing or hauling heavy loads. The EPA calculation serves as a standardized benchmark.

Real-world expectations

While the EPA estimates provide a useful point of comparison, real-world fuel economy for the 2015 Expedition EL depends heavily on driving style and usage. Aggressive acceleration, frequent hard braking, and consistent towing will significantly decrease MPG. Gentle driving and prioritizing highway miles can bring you closer to the EPA’s 21 MPG highway figure. Owners report a wide range of fuel economy, influenced by whether they are primarily using it as a family vehicle or a dedicated tow rig. Regular maintenance, including tire inflation and filter changes, also plays a role. To get a sense of EXPEDITION MPG across all years, consider browsing owner forums for detailed fuel logs and discussions.

How it compares

Compared to its contemporaries, the 2015 Expedition EL’s fuel economy is typical for a large, body-on-frame SUV. A 2015 Chevrolet Suburban 2WD with the 5.3L V8 is rated at 16 MPG combined, while a 2015 Toyota Sequoia 2WD checks in at 15 MPG combined. The Nissan Armada, which had a larger 5.6L V8, comes in even lower. These SUVs prioritize interior space, towing capacity, and durability over fuel efficiency, a trade-off buyers are typically aware of when making their purchase. For those considering alternatives, all Ford fuel economy data shows the Expedition Max (the updated name for the EL) is similar in ratings to its GM and Toyota competitors.

Tips to maximize efficiency

The 3.5L EcoBoost engine in the 2015 Expedition EL is sensitive to driving style. Avoid unnecessary hard acceleration and maintain a steady speed whenever possible. Using cruise control on the highway helps to optimize fuel consumption.

Proper tire inflation is critical for maximizing fuel efficiency. Check your tire pressure regularly and ensure it matches the recommended PSI found on the driver’s side door jamb. Underinflated tires create more rolling resistance, which forces the engine to work harder and burn more fuel.

Reduce unnecessary weight. The more weight you carry, the harder the engine has to work, and the lower your fuel economy will be. Remove any items from the vehicle that are not essential, especially heavy objects. A clean cargo area is an efficient cargo area.

Consider using the tow/haul mode only when actually towing. This mode alters the transmission’s shift points to optimize performance under heavy loads, but it can decrease fuel economy when used unnecessarily. Operate the vehicle in its standard drive mode unless you need the extra towing assistance.
