The 2023 Jeep Grand Cherokee L 4WD with the 3.6L V6 gets 21 MPG combined. This isn’t Prius territory, and those shopping for a three-row SUV to frequently carry kids and cargo likely aren’t expecting it to be. That 21 MPG represents a reasonable compromise for buyers who want space, strong capability, and the Jeep image, but also modern levels of comfort and technology.

City and highway performance

The EPA estimates the Grand Cherokee L 4WD gets 18 MPG in the city and 25 MPG on the highway. The lower city figure reflects stop-and-go traffic and the vehicle’s weight. During steady cruising, especially with cruise control, the 25 MPG highway number is more achievable. The Grand Cherokee L is a larger vehicle, and driving in cities and navigating tight parking takes a toll on efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Jeep Grand Cherokee L 4WD 3.6L V6 at $2,100. This is based on driving 15,000 miles per year and assumes current national average fuel prices. It’s a useful comparison benchmark, but your actual costs will vary based on your location, driving habits, and gas prices. Aggressive driving, frequent short trips and consistent four-wheel-drive use will all increase your fuel costs.

Real-world expectations

While the EPA figures provide a standardized measure, real-world fuel economy often differs. Grand Cherokee L drivers report mixed results. Those who primarily use the vehicle for highway commuting often report numbers close to the EPA’s 25 MPG. However, owners who spend most of their time in congested urban areas tend to see figures closer to, or even slightly below, the 18 MPG city estimate. Even occasional towing will significantly lower your average. Driving style is important. Smooth acceleration and consistent speeds will save fuel.

How it compares

The Grand Cherokee L’s fuel economy is average compared to its rivals. The Toyota Highlander gets a combined 24 MPG with its standard V6 engine, an improvement. The Kia Telluride manages a combined 21 MPG, matching the Grand Cherokee L 4WD’s rating. However, the Ford Explorer, particularly with its standard 2.3L EcoBoost engine and four-wheel drive, achieves around 23 MPG combined. Fuel economy is critical for buyers comparing these vehicles, who must weigh fuel cost against factors such as interior space, towing capacity, and brand preference.

Tips to maximize efficiency

The Grand Cherokee L weighs over 4,700 pounds. That mass takes energy to accelerate, so accelerate smoothly and gradually from a stop. Anticipating traffic flow and avoiding harsh braking will also conserve fuel. Hard braking converts forward momentum into wasted heat.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended specifications listed on the door jamb sticker.

Only use four-wheel-drive when necessary. Driving in 4WD on dry pavement puts strain on the drivetrain and reduces fuel economy. Keep it in two-wheel-drive mode unless you encounter snow, ice, or loose gravel.

Avoid idling for extended periods. If you’re waiting for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling consumes fuel unnecessarily.

Remove unnecessary cargo or roof racks. Extra weight and aerodynamic drag negatively impact fuel economy. A clean roof and an empty cargo area will help improve miles per gallon. Occasionally check your air filter and replace if necessary, as a clogged air filter can restrict airflow to the engine, reducing efficiency.
