Driving Habits:
* Drive smoothly: Aggressive acceleration and braking are major gas guzzlers. Accelerate gradually and anticipate stops to avoid harsh braking.
* Maintain consistent speed: Cruising at a steady speed, especially on highways, is much more fuel-efficient than constantly accelerating and decelerating. Try to stay within the optimal speed range for your Wrangler (check your owner's manual).
* Avoid idling: Turn off your engine if you're stopped for more than a minute or two.
* Use cruise control: On the highway, cruise control helps maintain a consistent speed, improving fuel economy.
* Lighten your load: Every extra pound reduces your fuel efficiency. Remove unnecessary items from your Jeep. Roof racks and other accessories also increase wind resistance.
* Proper tire inflation: Under-inflated tires increase rolling resistance, leading to lower gas mileage. Check and inflate your tires to the recommended pressure (found on the sticker inside your driver's side doorjamb or your owner's manual).
Vehicle Maintenance:
* Regular maintenance: Keep your Jeep well-maintained. This includes regular oil changes, air filter replacements, and other scheduled services as recommended in your owner's manual. A properly tuned engine burns fuel more efficiently.
* Check your alignment: Poor wheel alignment can significantly reduce fuel economy.
* Aerodynamic improvements (with caution): While a Wrangler's boxy design inherently limits aerodynamics, consider a low-profile roof rack (if needed) and removing any unnecessary exterior accessories that increase wind resistance. Avoid significant modifications that could negatively impact off-road capability.
Other Considerations:
* Fuel type: Using the recommended fuel type specified in your owner's manual is crucial.
* Driving conditions: Factors like terrain, weather (headwinds), and traffic will all impact your gas mileage.
* Tire type: All-terrain or mud-terrain tires have more rolling resistance than highway tires, impacting fuel economy. If you primarily drive on paved roads, consider highway-terrain tires (though this will likely reduce off-road capability).
Realistic Expectations: Even with all these optimizations, a Jeep Wrangler will never achieve the gas mileage of a sedan or compact car. Focus on incremental improvements rather than expecting dramatic changes. The improvements you see will depend on your driving habits and the condition of your vehicle.
