The 2022 Jeep Grand Cherokee WK 2WD 3.6L gets 21 MPG combined. It’s a Jeep Grand Cherokee, the older WK generation sold alongside the newer WL model. Its purpose is comfortable, spacious transportation with some reliable capability. Buyers are often repeat Grand Cherokee owners, value-focused shoppers who appreciate its proven reliability and familiar design, or those who need a capable vehicle for occasional towing without spending too much.

City and highway performance

The EPA estimates the 2022 Grand Cherokee WK 2WD 3.6L achieves 19 MPG in the city and 26 MPG on the highway. That highway number is especially important for owners who regularly take longer trips, for family vacations or weekend getaways. The city figure reflects stop-and-go traffic, where the Grand Cherokee’s weight and non-hybrid powertrain consume more gas. The 8-speed automatic transmission tries to keep the engine in its most efficient range. These numbers aren’t class-leading, but they’re within the acceptable range for a vehicle of this size and purpose.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Jeep Grand Cherokee WK 2WD 3.6L at $2,100. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the gas prices in your area. Heavy acceleration, frequent short trips, and aggressive driving will increase those costs, while smooth driving and maximizing highway miles will help keep them down.

Real-world expectations

The EPA estimates provide a baseline, but real-world MPG often differs. Expect some variation based on driving style, terrain, and load. Owners who regularly tow or carry heavy loads will see a decrease in fuel economy. Those who primarily drive on flat highways at consistent speeds may exceed the EPA’s 26 MPG highway estimate. Monitoring your fuel consumption over time using a fuel tracking app or logging your fill-ups can give you a more accurate picture of your Grand Cherokee’s MPG in your specific driving conditions. The GRAND MPG across all years can be useful as you research your next vehicle.

How it compares

The 2022 Grand Cherokee WK 2WD 3.6L faces competition from other mid-size SUVs. The Toyota 4Runner, another body-on-frame SUV, typically achieves around 17 MPG combined with its V6 engine. A Honda Passport, with its more modern design and focus on efficiency, reaches approximately 22 MPG combined. The newer WL-generation Grand Cherokee with the same 3.6L engine achieves slightly better numbers at 22 MPG combined, thanks to its improved aerodynamics and weight savings. For those willing to consider smaller vehicles, a Mazda CX-5 offers significantly better fuel economy, hitting 28 MPG combined in its base trim, but sacrifices space and towing capability.

Tips to maximize efficiency

Maintain proper tire pressure. 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 level, which can be found on the sticker located on the driver’s side doorjamb or in your owner’s manual.

Avoid excessive idling. Letting your Grand Cherokee idle for extended periods, especially in cold weather, wastes fuel. If you’re going to be stopped for more than a minute, it’s more efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, so there’s no need to worry about excessive wear.

Drive smoothly and avoid aggressive acceleration. Rapid acceleration burns significantly more fuel than gradual acceleration. Anticipate traffic conditions and maintain a steady speed whenever possible. Using cruise control on the highway can help maintain a consistent speed and improve fuel efficiency.

Lighten the load. Carrying unnecessary weight in your Grand Cherokee reduces fuel economy. Remove any items from your cargo area that you don’t need, such as unused sporting equipment or tools. The lighter your vehicle, the less effort the engine needs to exert, and the less fuel it will consume.

Consider a fuel additive. Certain fuel additives can help clean fuel injectors and improve combustion efficiency, but this isn’t guaranteed. Look for additives specifically designed for modern gasoline engines and follow the manufacturer’s instructions carefully. Some additives may not provide significant benefits for every vehicle and the impact can be minimal.
