19 MPG combined. That’s the EPA estimate for the 2023 Jeep Wagoneer 4WD with its 3.0L inline-six engine. Before you recoil, consider this: you’re talking about a body-on-frame SUV with seating for up to eight and the off-road capability to handle more than just gravel driveways. It has the presence to turn heads everywhere it goes. Nobody buys a Wagoneer to save gas like a Prius. They buy it for its sheer capability and space, trading efficiency for a unique blend of old-school ruggedness and modern luxury.

City and highway performance

The official EPA estimates break down as 16 MPG in the city and 23 MPG on the highway. That city figure highlights the Wagoneer’s disadvantage. It has considerable weight. Stop-and-go traffic demands a lot of energy to get this large SUV moving, and then more energy to brake. On the open road, the Wagoneer’s fuel economy improves as the engine settles into a more efficient cruising speed. The eight-speed automatic transmission helps, keeping the engine in its optimal power band. Still, the aerodynamic brick-like shape of the Wagoneer will always work against it at higher speeds. Expect better numbers if you stick to below 70 mph.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Jeep Wagoneer 4WD is $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that rising fuel prices can quickly inflate that number, and your individual driving habits will affect the actual cost. If you spend most of your time in congested urban environments, that $2,300 figure could prove optimistic. Similarly, if you are regularly towing or using four-wheel-drive, you can expect to spend more on fuel.

Real-world expectations

While the EPA provides a standardized measurement, real-world experience varies. Most owners report figures close to the EPA’s estimate, but factors like driving style, terrain, and ambient temperature will all play a role. Aggressive acceleration and hard braking will quickly deplete your fuel. Driving in mountainous terrain will stress the engine, decreasing efficiency. Cold weather reduces fuel economy due to denser air and longer engine warm-up times. Towing, naturally, has a significant impact. Accept that you will likely see a MPG figure slightly below the EPA rating, especially in demanding conditions.

How it compares

Within the full-size SUV segment, the Wagoneer’s fuel economy lands about where you might expect. The Ford Expedition with its 3.5L EcoBoost V6 is rated at 17 MPG city / 23 MPG highway / 19 MPG combined for the 4×4 version, matching the Wagoneer’s combined rating, though with slightly different city/highway splits. A Chevrolet Tahoe 4WD with the 5.3L V8 achieves 15 MPG city / 20 MPG highway / 17 MPG combined. The Nissan Armada 4WD, also powered by a V8, lags further behind at 13 MPG city / 18 MPG highway / 15 MPG combined. More efficient alternatives exist, like the hybrid Toyota Sequoia, but it does not offer the same old-school Jeep character and capability. You may also want to cross-shop WAGONEER MPG across all years to see if you can find a model that better meets your needs. For those prioritizing fuel economy, the Wagoneer might not be the first choice, but it’s a reasonable compromise for its target audience, and you can view all Jeep fuel economy data to know there are other options available. It’s a matter of understanding priorities.

Tips to maximize efficiency

Avoid excessive idling. The Wagoneer’s large engine consumes a surprising amount of fuel when stationary. If you anticipate waiting for more than a minute or two, shut off the engine and restart it when it’s time to move. Modern starters are designed for frequent use.

Monitor your tire pressure. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, following the manufacturer’s recommendations listed on the doorjamb. A simple tire pressure gauge can make a significant difference over time.

Anticipate traffic flow. Avoid sudden acceleration and harsh braking by looking ahead and anticipating traffic patterns. Maintaining a steady speed not only improves fuel economy, but also enhances safety and reduces wear and tear on your vehicle.

Reduce unnecessary weight. Carrying heavy items in your Wagoneer that aren’t needed for your trip impacts fuel efficiency. Remove any unnecessary cargo to lighten the load and improve mileage. Even small weight reductions can add up over time.
