20 MPG combined isn’t impressive for many modern vehicles, but for the 2018 Jeep New Wrangler 4WD 3.6L 6-cyl, it’s simply a trade-off. People buy a Wrangler for its unmatched off-road capability, its iconic design, and the feeling of freedom that comes with removing the top and doors, not for great gas mileage. This generation of Wrangler, known as the JL, was an improvement over the previous JK. Even so, fuel economy is a secondary concern for its dedicated fanbase.

City and highway performance

The EPA estimates the 2018 Jeep New Wrangler 4WD with the 3.6L V6 and 8-speed automatic gets 18 MPG in the city and 23 MPG on the highway. These figures show the Wrangler’s aerodynamic challenges and the demands of its four-wheel-drive system. The city number is lower because of the Wrangler’s weight and boxy shape. Highway fuel economy, while slightly better, is still not great, especially considering wind resistance which becomes significant at higher speeds.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Jeep New Wrangler 4WD 3.6L 6-cyl is $2,200. This is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on driving habits, fuel prices in your area, and the actual number of miles driven annually. Check all Jeep fuel economy data when considering your options.

Real-world expectations

The EPA estimates are a guideline, not a guarantee. Wrangler owners report fuel economy that fluctuates around the official numbers. Some see slightly better results on long highway trips, and others experience lower MPG in city driving or with larger tires and lift kits. Off-road driving will reduce fuel economy, as will aggressive driving. Review NEW MPG across all years to understand potential savings.

How it compares

The 2018 Wrangler’s fuel economy is comparable to other off-road SUVs. For example, the Toyota 4Runner, another body-on-frame SUV known for its reliability, gets an EPA-estimated 17 MPG combined. The lighter, more road-focused Jeep Grand Cherokee 4×4 with its V6 engine manages around 21 MPG combined, an improvement because it lacks the solid front axle and extreme off-road focus of the Wrangler. Even a modern SUV like the Ford Bronco with the 2.3L EcoBoost engine offers slightly better MPG numbers, but is still in the same range. The Wrangler’s appeal is its capability and open-air freedom, factors that outweigh fuel economy concerns for many buyers.

Tips to maximize efficiency

Make sure your tires are properly inflated. The Wrangler often runs on larger, more aggressive tires for off-road use, but maintaining correct tire pressure, as indicated on the tire placard, can minimize rolling resistance and improve fuel economy. Regularly check tire pressure, especially after temperature changes, to save fuel.

Avoid unnecessary weight. Removing extra gear from the vehicle that isn’t needed can reduce the load on the engine and improve fuel economy. This to Wranglers, which owners often equip with accessories.

Drive smoothly and avoid aggressive acceleration. The Wrangler’s 3.6L V6 engine delivers power, but using it sparingly can make a difference. Gentle acceleration and avoiding hard braking can conserve fuel. Anticipating traffic and maintaining a steady speed also contribute to better efficiency.

Consider limiting your highway speed. While the Wrangler is capable of highway speeds, its aerodynamics are not ideal. Reducing your speed by even 5-10 mph can result in fuel savings. The faster you go, the more fuel you burn fighting wind resistance.

Service your vehicle regularly. Maintaining your Wrangler with scheduled maintenance, including oil changes, air filter replacements, and spark plug replacements, will ensure the engine is running efficiently. A well-maintained engine consumes less fuel and performs optimally.
