Thanks to the diesel engine’s efficiency, Wranglers with this powertrain achieve more than the average mileage of most models. 

0L EcoDiesel V6 Engine

As per EPA rating, 3.0L EcoDiesel V6 Engine engines have:

  • Rubicon: 23 combined mileage and 21 and 26 MPG in cities and highways. 
  • Other models: Regular Jeep Wranglers offer 29 and 22MPG in highways and cities with a combined EPA of 25MPG

Transmission System:

Jeep Wranglers have a 6-speed manual transmission option for its entire lineup. No doubt, the manual transmission offers more control to the driver. Nonetheless, it can be slightly less fuel-efficient than its automatic counterparts. 

The lesser fuel efficiency happens due to potential variations in shifting habits. However, the difference in fuel efficiency between manual and automatic transmissions is not so significant, especially on highways. 

The 8-speed automatic transmission is a popular choice among Wrangler buyers. It contributes to better fuel efficiency thanks to its optimized gear shifting and smoother operation. Hence, Wranglers with automatic transmissions offer more consistent and predictable fuel economy figures.

Driving Conditions

Wranglers generally achieve lower fuel efficiency than highway driving in urban or city driving conditions. Frequent stops, idling, and acceleration in city traffic can reduce the overall mileage of all the Wrangler models. The 2.0L Turbocharged 4-cylinder engine may fare better in city driving due to its smaller and more fuel-efficient engine.

On highways, Wranglers often perform at their best. The consistent speeds and minimal stops allow the vehicle to operate optimally, resulting in higher mileage figures.

Off-road adventures typically demand more power and fuel consumption. Rough terrain, inclines, and obstacles require additional energy to navigate. As a result, off-road driving for Jeep Wranglers tends to reduce fuel efficiency compared to on-road driving conditions.

Driving Habits:

Aggressive driving is responsible for reduced mileage on all vehicles. Rapid acceleration, sudden braking, and high-speed driving significantly reduce fuel efficiency. So, Wrangler drivers who frequently engage in aggressive driving may experience lower mileage. It is substantially lower than those who adopt a more conservative driving style.

Maintaining a steady speed, avoiding abrupt stops and starts, and using cruise control on highways can maximize fuel efficiency. Wrangler owners with a smooth, steady driving approach will achieve better mileage results.

Tips for Maximizing Fuel Efficiency in a Jeep Wrangler:

Jeep Wrangler is more than reliable for both on and off-road driving. However, their fuel efficiency remains highly questionable. So, you should carefully apply different techniques to improve its mileage. 

Use Good Tires:

The best way to improve vehicle mileage is to use tires with excellent traction and an appropriate size. High-quality tires roll smoothly, while worn-out or low-traction tires can increase energy consumption. Naturally, it will negatively impact fuel efficiency. 

Additionally, consider adjusting the gear ratio for optimal mileage if you frequently use larger off-road tires. Also, ensure the tire pressure remains 35 to 40 PSI, as the Wrangler users say. 

Use Low-Weight Wheels: 

The weight of wheels and tires significantly affects rolling resistance and fuel consumption. Heavy wheels increase rolling friction and fuel consumption. While heavier bead-lock wheels may be necessary for off-road performance, they also focus on fuel efficiency. 

Therefore, choose tires that meet both fuel economy and weight-bearing capacity perfectly. 

Engine Maintenance: 

Proper engine maintenance is crucial for better fuel economy. Routine maintenance tasks for Jeep include:

  • Cleaning spark plugs and spark plug wires, 
  • Changing the air filter for proper engine ventilation,
  • Regularly replacing the engine oil and oil filter. 

Additionally, the right exhaust system can improve ventilation to reduce fuel waste.

Reduce Jeep Weight: 

A fully loaded Jeep with excessive cargo can decrease fuel efficiency. Each additional pound increases rolling resistance, resulting in reduced fuel economy. To improve mileage, consider using lightweight components, such as plastic flares, instead of aluminum or steel fenders.

Install Hood Latches: 

Some Jeep Wrangler owners report experiencing hood flutter. It can impact engine ventilation and fuel efficiency. You need to install hood latches to secure the hood in place. The hood latches maintain proper ventilation and, in some cases, lead to better fuel efficiency.
