Jeep Wrangler Fuel Economy

Besides knowing How many gallons of gas does a 2022 Jeep Wrangler hold, it is important to consider how many miles you can get out of each gallon from it. Because off-road terrains are often harsh, you would need a lot of power to get out of tricky scenarios.

So, off-road vehicles usually have the ability for all this thrill and adventure, but huge power consumption empties your tank a lot quicker. That is why your vehicle engine should be efficient enough to generate more power using a moderate amount of fuel.

Wrangler is quite an efficient vehicle, giving you a handsome fuel average per gallon. Most trim levels show an average of 17 mpg in city and 25 mpg on the highway.

How To Get More Mileage On Jeep Wrangler?

With fuel prices hiking every day, better fuel economy is getting more and more important for every driver out there. So, here are a few tips to maximize the gas mileage on your Wrangler;

1. Use Good Tires

Tires play an important role in determining the fuel average of your vehicle. A tire with good traction features rolls smoothly, while a tire that is worn out or has poor traction uses more energy from the engine to keep rolling.

Also, the size of the tires is important. When you use bigger MT or RT tires, you increase the Jeep’s weight, and resultantly, rolling resistance also goes up. Hence, you have to find a middle point, i.e., a tire that is hefty enough for off-road excellence but not too big to wreck your budget with a poor fuel average.

One way to do so is re-gearing. Get the gear ratio altered at a service station to match the tire size you often use. For good mileage with bigger tires, a lower gear ratio works best. But this modification is quite costly, and you need an expert’s opinion to reset the ratio.

If you go off-road only occasionally, you can store big tires for those trips in your garage and use smaller tires for everyday purposes.

2. Use Low-Weight Wheels

The heavier your Jeep is, the less fuel efficient it becomes. Besides that, the weight of wheels and tires impacts rolling resistance more than the weight of passengers and luggage. If you put on heavy wheels, rolling friction and fuel consumption will subsequently increase. In contrast, low-weight wheels will save your fuel budget.

But sometimes, heavy bead-lock wheels become essential for the off-road abilities you want. Hence, you will have to find a balance between off-road performance and fuel efficiency.

3. Engine Maintenance

Poor maintenance can dramatically increase the fuel average, upsetting your balance sheets. Hence, you can save a lot on fuel if you put in some effort and time to take care of your SUV. Especially engine maintenance is a must for better fuel economy.

  • Clean spark plug and spark plug wires routinely.
  • Change the Air filter to keep the engine properly ventilated.
  • Get the engine oil replaced after some time. Also, change the oil filter regularly.

To go a step ahead, you can install an exhaust to improve ventilation and avoid overheating and fuel waste.

4. Reduce Jeep Weight

Do not load your Jeep with stuff if you want a good fuel average. Every pound on your SUV increases the rolling resistance, dragging the fuel level down.

You can cut down weight by using plastic flares instead of aluminum/steel fender/metallic ones. Everything from bumpers, rooftop tents, and flares to luggage you put in your Jeep to its tires and wheel adds some weight and affects fuel economy.

5. Install Hood Latches

With Jeep Wrangler, you often experience a hood flutter issue. It is not a matter of concern for most people. But some drivers say they get better averages after installing hood latches to prevent hood fluttering.

A fluttering hood can cause air to come in and get stuck there, leading to poor engine ventilation. That is why the engine becomes more efficient when hood latches hold the hood firmly in its place.

Which Jeep Wrangler gets the best gas mileage?

Jeep Wrangler was ranked below other Jeep line-ups like Jeep Renegade, Jeep Compass, and   Cherokee until the launch of Jeep Wrangler 4xe in 2021. This car has an electric motor to power up its engine besides gasoline combustion, giving the best fuel average among Wrangler models.

  • When driving in hybrid mode (electric motor plus gasoline), you get 49 miles per gallon.
  • When not using electric power, it gives you 20 miles per gallon on gas like other models.
