19 MPG combined is the fuel economy for the 2024 Jeep Wagoneer L 4WD with the 3.0L inline-six. Nobody choosing this extended-length SUV expects Prius-like efficiency. The Wagoneer L is about space, presence, and capability. It’s a hauler, a family vehicle, and sometimes even an off-roader. Its fuel consumption is a tradeoff accepted by buyers who prioritize volume and towing capacity over trips to the gas station.

City and highway performance

The EPA estimates the Wagoneer L 4WD at 16 MPG in the city and 23 MPG on the highway. The city figure reflects the stop-and-go driving in urban environments, where the Wagoneer L’s mass requires more energy to repeatedly accelerate from a standstill. On the open road, the 8-speed automatic transmission helps optimize fuel economy at cruising speeds, but even then, aerodynamic drag and the engine’s inherent thirst keep that highway number relatively low. Owners who frequently tow will find the highway MPG drops even further.

Annual fuel cost

The EPA estimates an annual fuel cost of approximately $2,300, given the Wagoneer L’s fuel consumption. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and assumes current national average fuel prices. It is useful for comparison against other vehicles, though individual fuel costs will vary depending on driving habits and local fuel prices. Heavy reliance on city driving, or frequent towing, will push that number higher. Exploring all Jeep fuel economy data can help put this cost into perspective.

Real-world expectations

While some drivers may occasionally match or slightly exceed the EPA highway estimate, consistently achieving 23 MPG is unlikely for most Wagoneer L owners. The vehicle’s size and weight, combined with the powerful engine, lead to higher fuel consumption, especially during aggressive acceleration or when carrying heavy loads. Owners report a realistic average falling somewhere between the city and combined EPA estimates.

How it compares

The Wagoneer L’s fuel economy is typical for its class. A comparable 2024 Chevrolet Suburban 4WD with the 5.3L V8 is rated at 16 MPG combined, only slightly behind the Wagoneer L, while the Ford Expedition Max 4×4 with the 3.5L EcoBoost V6 manages a similar 19 MPG combined. The Nissan Armada 4WD, with its 5.6L V8, sits lower at 15 MPG combined. A BMW X7 xDrive40i, though smaller, achieves 21 MPG combined, highlighting the compromises in choosing a massive SUV like the Wagoneer L. The WAGONEER MPG across all years shows its fuel economy has seen improvements and small variations.

Tips to maximize efficiency

Gentle acceleration is key to saving fuel in the Wagoneer L. Avoid aggressive starts and hard braking, allowing the vehicle to gradually gain speed. The inline-six delivers plenty of torque at lower RPMs, so there’s no need to push the engine hard to get moving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Check the tire pressure regularly and inflate them to the recommended level found on the doorjamb sticker.

Reduce unnecessary weight. Carrying excess cargo adds to the vehicle’s overall weight, reducing fuel efficiency. Remove any items from the vehicle that aren’t needed.

Plan your routes to avoid stop-and-go traffic as much as possible, especially during peak hours. Constant acceleration and deceleration significantly decrease fuel economy. If possible, drive during off-peak hours or choose routes with fewer traffic lights.

Consider using cruise control on the highway. Maintaining a consistent speed can help optimize fuel efficiency, especially on long trips. However, be mindful of traffic conditions and disengage cruise control when necessary for safety.
