The 2023 Jeep Wagoneer 4WD with its 5.7L V8 gets 17 MPG combined. Frankly, no one buys a Wagoneer expecting Prius-like gas mileage. This is a large, body-on-frame SUV designed for serious towing, hauling, and family adventures. For the Wagoneer buyer, fuel economy is less important than capability and spaciousness, but understanding its limitations is critical before buying. This isn’t a daily commuter, it’s a tool for a specific job, and that job often involves more than just driving kids to soccer practice.

City and highway performance

The EPA estimates the 2023 Wagoneer 4WD at 15 MPG in the city and 20 MPG on the highway. The city number shouldn’t surprise anyone who’s driven a large displacement V8 in stop-and-go traffic. Its weight needs significant energy to get moving repeatedly. The 20 MPG highway number is more attainable, especially if you maintain a steady speed and avoid aggressive acceleration. The eight-speed automatic transmission makes the most of the engine’s powerband, but physics are physics, pushing a vehicle this large through the air requires fuel.

Annual fuel cost

The EPA says the annual fuel cost for the 2023 Jeep Wagoneer 4WD is $3,100. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices at the time of calculation. If you drive more than 15,000 miles annually, or if fuel prices in your area are higher than the national average, expect to spend more on fuel.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy often varies. Your MPG can be affected by factors such as driving style, traffic, and even tire pressure. Expect to see numbers close to the EPA estimates under ideal conditions, but aggressive driving or consistent towing will lower your fuel economy. Some owners report highway numbers slightly above 20 MPG when cruising at consistent speeds, while city driving can easily dip below 15 MPG in congested environments. Looking at the WAGONEER MPG across all years can give you more insight.

How it compares

The Wagoneer isn’t the only full-size SUV. The Chevrolet Tahoe 4WD with its 5.3L V8 is rated at 16 MPG combined, 15 city, and 19 highway, almost identical. Similarly, the Ford Expedition 4×4 with its 3.5L EcoBoost V6 earns an EPA of 19 MPG combined, 17 city, and 23 highway by reducing displacement and turbocharging. These differences, though small, add up over time. A buyer prioritizing fuel economy might consider the Expedition, but those drawn to the Wagoneer’s styling and V8 sound likely accept the trade-off.

Tips to maximize efficiency

Smooth acceleration and braking can improve fuel economy in a heavy vehicle like the Wagoneer. Avoid sudden bursts of speed and try to anticipate traffic flow to reduce unnecessary stops and starts. The 5.7L V8 rewards a gentle touch, hard acceleration burns a lot of fuel quickly.

Regular maintenance, including proper tire inflation and timely oil changes, is important for efficiency. Underinflated tires create more rolling resistance, forcing the engine to work harder. Similarly, old or degraded oil can increase friction within the engine, reducing fuel economy.

Consider using the Wagoneer’s Eco mode, if equipped. This mode typically adjusts throttle response and shift points to prioritize fuel efficiency. While it might slightly reduce performance, the difference is often negligible in normal driving.

When towing, be mindful of the added weight and aerodynamic drag. Reduce your speed and increase following distance to maintain safe stopping distances. The Wagoneer is capable, but towing significantly impacts fuel consumption.

Remove unnecessary cargo to reduce weight. While the Wagoneer is designed to haul a lot, every extra pound contributes to fuel consumption. Clearing out infrequently used items can make a small but noticeable difference over time.
