15 MPG combined is the number that hangs over the 2022 Jeep Grand Wagoneer 4WD 6.4L 8-cyl. This isn’t a vehicle people buy for saving fuel. The Grand Wagoneer buyer wants strong size, towing capacity, luxurious features, and iconic Jeep styling. They need to haul a boat to the lake, shuttle a crew to a ski weekend, or simply make a statement, and they accept the fuel cost as part of owning it.

City and highway performance

The numbers are 13 MPG in the city and 18 MPG on the highway. The city figure, showing stop-and-go traffic and the Grand Wagoneer’s weight, is particularly sobering. Drivers who spend most of their time in cities will see these numbers frequently. The EPA’s 18 MPG highway estimate is more achievable if you maintain a steady speed and avoid hard acceleration. Any heavy use of the gas pedal, especially when merging onto the Interstate, will send that number down fast.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 Jeep Grand Wagoneer 4WD 6.4L 8-cyl is $3,850. This is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is recommended, so this number could be higher depending on prices at your local stations. For owners who expect to drive over 15,000 miles annually, the cost of fuel will be a large part of their budget.

Real-world expectations

The EPA estimates offer a baseline, but your actual fuel economy will vary. Factors such as driving style, terrain, weather, and cargo weight affect fuel consumption. Towing, in particular, will have a big effect, potentially dropping mileage into the single digits, and even a light load will result in worse fuel economy. Hard starts and frequent use of the Grand Wagoneer’s power will also contribute to lower numbers. Expect to see figures lower than the EPA estimates, especially under demanding conditions.

How it compares

The Grand Wagoneer’s fuel economy places it at the bottom of its class. The Cadillac Escalade 4WD, with its 6.2L V8, manages a slightly better 16 MPG combined. Even the Lincoln Navigator 4×4 with its turbocharged V6 gets around 18 MPG combined. These differences are significant for buyers concerned about fuel costs over the long term. However, for Grand Wagoneer fans, its unique mix of heritage, capability, and style is worth it. You can view all Jeep fuel economy data to understand Jeep’s broader performance profile.

Tips to maximize efficiency

While the Grand Wagoneer isn’t designed for great fuel efficiency, there are things owners can do to reduce the impact. Avoiding hard acceleration is critical. The 6.4L V8 is eager to provide power, but each burst uses more gas. Gentle acceleration and anticipating traffic will improve your MPG.

Tire inflation is more important than you might think. Make sure your tires are inflated to the recommended pressure, as this reduces rolling resistance and improves fuel economy. Check tire pressure regularly.

Minimize idling. Letting the engine run wastes fuel. If you’re stopped for more than a minute or two, turn off the engine. Restarting consumes less fuel than idling.

Plan your trips and combine errands. Shorter trips with cold starts are less efficient than longer trips with a warmed-up engine. Consolidating tasks into one outing reduces cold starts.

Be mindful of accessory use. Running the air conditioner or other power-draining accessories puts extra strain on the engine and reduces fuel economy. Use these features sparingly, especially during short trips where they don’t add much comfort.

Careful driving will only help a little. If you’re worried about fuel consumption, consider alternatives in the large SUV segment. The Grand Wagoneer serves those who prioritize presence and capability over efficiency.
