How to Improve Jeep Wrangler Gas Mileage

how to improve jeep wrangler gas mileage

The Jeep Wrangler is a beloved vehicle for off-road enthusiasts, but its gas mileage is notorious for being poor. With gas prices steadily increasing, many Jeep Wrangler owners are looking for ways to improve their gas mileage.

But how to improve Jeep Wrangler gas mileage? This article will explore some of the most effective ways to improve your Jeep Wrangler’s gas mileage.

Drive More Efficiently

You must drive more efficiently if you want to know how to get better gas mileage in a Jeep Wrangler. Changing your driving habits is the simplest and most effective way to improve gas mileage. Accelerating and braking sharply and frequently can lower your gas mileage. Try accelerating smoothly and gradually and avoiding sudden stops to improve your efficiency.

Additionally, reducing your speed on the highway can help improve your gas mileage. Try keeping your speed around 55-60 mph, as driving at higher speeds can decrease fuel efficiency.

Check Your Tire Pressure

Proper tire pressure is crucial for good gas mileage. Underinflated tires can increase rolling resistance and cause your engine to work harder, lowering your gas mileage. Check your tire pressure regularly, at least once a month.

Make sure it matches the recommended pressure for your Jeep Wrangler. You can find the recommended tire pressure in your owner’s manual or the tire sidewall. Ensure the tires are inflated to the recommended pressure level specified in the owner’s manual.

Keep Up With Regular Maintenance

Regular maintenance is essential to keep your Jeep Wrangler running smoothly and efficiently. Dirty air filters, worn spark plugs, and low engine oil cam all decrease your gas mileage. Regular maintenance will make the vehicle run smoother, faster, and more efficient.

As a Jeep owner, you must ensure that the spark plug and the wires are all intact. Also, you need to ensure that the air filters are in excellent shape and that the carbon intake is free from dirt and debris. These steps will ensure the vehicle runs smoothly and improve gas mileage.

Upgrade to a More Efficient Air Intake System

Upgrading your air intake system can improve your Jeep Wrangler’s gas mileage by allowing more air into the engine, improving combustion efficiency. Many air intake systems are available for the Jeep Wrangler, which can help improve your gas mileage.

Remove Excess Weight

Excess weight in your Jeep Wrangler can cause your engine to work harder, decreasing your gas mileage. Remove unnecessary items from your Jeep, such as heavy cargo or unused roof racks, to help improve your gas mileage.

It is interesting to note that many Jeep owners overlook the impact of keeping so many items inside the vehicle can affect the fuel efficiency of the vehicle. Everything you keep inside the Jeep Wrangler affects the gas mileage, big or small.

If you are using the vehicle for long trips, consider using a utility trailer to put all the things inside. Doing this step will make sure that the vehicle will have optimum fuel efficiency during the whole duration of the trip.

Using the Correct Fuel

Using the correct fuel can also help improve your gas mileage. Your Jeep Wrangler is designed to run on regular unleaded gasoline, and using a higher-octane fuel is unlikely to improve your gas mileage. Stick to the manufacturer’s recommended fuel type to optimize your gas mileage.

Install a More Efficient Exhaust System

Upgrading to a more efficient exhaust system can help improve your Jeep Wrangler’s gas mileage by reducing exhaust restrictions, which can improve engine efficiency. A high-performance exhaust system can reduce the backpressure, improving engine efficiency and increasing gas mileage.

As for your part, you must look for exhaust systems designed to improve gas mileage and ensure they are compatible with your Jeep Wrangler’s engine.

Use Cruise Control

Cruise control is a feature in most modern vehicles that allows the driver to maintain a constant speed without using the accelerator pedal. Once the desired speed is set, the vehicle’s computer system will maintain that speed until the driver applies the brakes or turns off the system.

Cruise control can be particularly useful on long road trips, allowing the driver to rest their foot and maintain a consistent speed. Cruise control can help improve your Jeep Wrangler’s gas mileage by avoiding unnecessary acceleration and deceleration.

Using cruise control is also a safe driving practice, as it can help prevent the driver from unintentionally exceeding the speed limit. Additionally, cruise control can help reduce driver fatigue, allowing the driver to focus on the road ahead without constantly adjusting their speed.

However, it is essential to remember that cruise control should not be used in hazardous driving conditions, such as heavy rain or snow, as it can reduce the driver’s ability to react quickly to changing road conditions.

Consider Aerodynamic Considerations

Aerodynamic considerations, such as front air dams or side skirts, can help reduce air resistance and improve your Jeep Wrangler’s gas mileage. These modifications are more effective at higher speeds, so they may not make a noticeable difference in city driving.


As shown in this article, there are many ways on how to improve Jeep Wrangler gas mileage. From simple changes to your driving habits to upgrading vehicle components, these changes can help increase the vehicle’s fuel efficiency. Following the tips above can help reduce fuel consumption and save money at the pump.
