17 MPG combined isn’t going to win any fuel-sipping contests, but for the 2022 Jeep Grand Cherokee L 4WD with its reliable 5.7L V8, it’s a trade-off many buyers willingly accept. This isn’t a vehicle purchased for hypermiling; it’s a statement, a commitment to capability and space. Think families who regularly tow a boat to the lake, skiers who navigate snowy mountain passes, or anyone who simply appreciates the commanding presence and confident power delivery that a V8 Grand Cherokee provides.

City and highway performance

The EPA estimates 14 MPG in the city and 22 MPG on the highway for this Grand Cherokee L configuration. The city figure reflects the inherent inefficiencies of stop-and-go driving with a large displacement engine. The highway number is a more palatable figure, aided by the 8-speed automatic transmission that allows the engine to cruise at lower RPMs. While 22 MPG is achievable on long highway stretches, expect that number to dip if you have a heavy foot or are battling headwinds. The reality is this: the bigger the load, the lower the MPG. The engine will compensate, as expected, but it will impact fuel economy.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,100 for the 2022 Jeep Grand Cherokee L 4WD 5.7L V8. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, using national average fuel prices. Keep in mind that your actual fuel costs may vary depending on your driving habits, fuel prices in your area, and the grade of fuel you use. If you drive more aggressively or spend more time idling in traffic, expect to exceed that $3,100 figure. Conversely, if you primarily stick to highway driving and practice efficient driving techniques, you might be able to come in slightly under that estimate.

Real-world expectations

While the EPA provides a standardized baseline, real-world fuel economy is heavily influenced by individual driving styles and conditions. Grand Cherokee L owners with the 5.7L V8 often report figures close to the EPA estimates, but with considerable variance. Expect to see numbers closer to the low end of the range if you frequently tow, drive aggressively, or spend most of your time in stop-and-go traffic. Some drivers report achieving slightly better highway MPG than the EPA estimate when driving conservatively on long trips. Ultimately, your mileage will vary, and it’s important to factor this in when considering the overall cost of ownership.

How it compares

The fuel economy of the 2022 Jeep Grand Cherokee L 4WD 5.7L V8 naturally invites comparison with its competitors in the mid-size SUV segment. For example, the Ford Explorer with its available 3.0L EcoBoost V6 achieves a combined 23 MPG, a significant advantage. Even the V8-powered Toyota 4Runner, a rugged body-on-frame SUV, manages around 17 MPG combined, although its ancient 5-speed transmission doesn’t help its highway numbers. The Dodge Durango with the 5.7L Hemi, which shares its powertrain with the Grand Cherokee L, achieves very similar fuel economy figures. Buyers choosing the Jeep are making a conscious choice, often prioritizing the V8’s power and towing capability over outright fuel efficiency.

Tips to maximize efficiency

Resist the temptation to floor the accelerator at every opportunity. The 5.7L V8 is capable of impressive acceleration, but using that power frequently will significantly impact fuel economy. Gentle acceleration and maintaining a steady speed are key to maximizing MPG. This engine responds well to smooth inputs; aggressive driving will only empty your wallet faster.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended level, typically found on a sticker inside the driver’s side door or in your owner’s manual. This simple maintenance task can make a noticeable difference.

Avoid extended idling. Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, and even brief periods of idling can add up over time, especially in these larger engines.

Plan your trips and combine errands to minimize cold starts. Cold starts are particularly inefficient as the engine requires more fuel to reach its optimal operating temperature. By consolidating multiple short trips into a single longer journey, you can reduce the number of cold starts and improve your overall fuel economy. Using GPS may point you to the most fuel efficient route, helping increase economy.

Regular maintenance is critical. A well-maintained engine operates more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. Neglecting these services can lead to reduced performance and decreased fuel economy.
