The 17 MPG combined fuel economy of the 2024 Jeep Grand Wagoneer 4WD with the 3.0L inline-six engine doesn’t tell the whole story. This vehicle isn’t for those primarily focused on minimizing their carbon footprint or saving money on gas. The Grand Wagoneer is a statement about American luxury and capability. Buyers want space, power, and presence, and are willing to pay for it at the pump.

City and highway performance

EPA estimates show the Grand Wagoneer gets 14 MPG in the city and 20 MPG on the highway. The city MPG reflects the engine’s work to move the heavy vehicle in stop-and-go traffic. The 20 MPG highway rating is better, suggesting the engine works less at consistent speeds, helped by its eight-speed automatic transmission. Your driving habits will significantly affect these numbers. If you accelerate hard and take frequent short trips, expect lower fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Jeep Grand Wagoneer 4WD 3.0L 6-cyl at $3,400. This is based on driving 15,000 miles per year and using the national average fuel price. Fuel prices change, so your actual cost will vary depending on your location and driving. While this is a big expense, Grand Wagoneer buyers likely expect it. They care less about saving every penny on gas and more about the comfort and utility this vehicle offers.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary. Driving style, terrain, weather, and cargo weight all affect it. Grand Wagoneer drivers who often tow or drive on difficult terrain can expect even lower MPG. However, those who drive mostly on the highway with a light load and easy acceleration may slightly exceed the EPA’s estimates. You can realistically expect a range of 13-18 MPG in combined driving.

How it compares

The Grand Wagoneer’s fuel economy is similar to other large, luxury SUVs. The Cadillac Escalade 4WD, with its 6.2L V8, gets a similar 16 MPG combined. The Lincoln Navigator 4×4 gets 17 MPG combined. The lower trim Expedition with its less powerful V6 gets similar or slightly better ratings. These trucks are built similarly and buyers should look at all Jeep fuel economy data.

Tips to maximize efficiency

Even though lower fuel costs aren’t the main concern, some driving habits can help you use less gas in the Grand Wagoneer. Avoid accelerating hard and braking hard, as this makes the engine work harder and burn more fuel. Accelerating gradually and coasting when you can will make a difference.

Make sure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure regularly and keep it at the right level as shown on the tire placard or in your owner’s manual.

Minimize idling, especially when the engine is cold. Modern engines warm up quickly while driving, so you don’t need to let the engine idle for long. If you’ll be stopped for more than a minute, turn off the engine.

Reduce extra weight. Carrying cargo you don’t need in the Grand Wagoneer adds to its weight, which directly affects fuel economy. Remove items that aren’t essential, such as tools you rarely use. This small change can improve efficiency. It is especially important to keep in mind when looking at GRAND MPG across all years, as weight has changed.
