Are Jeep Wranglers Good on Gas? All You Need To Know

Fuel efficiency and Jeep Wranglers, well, these two things really don’t go hand to hand. Well, the manual versions do provide slightly better mileage than the automatic ones. However, the customers aren’t really very pleased with how the vehicle performs in this regard.

Nevertheless, we’re here to see exactly how efficient Jeep Wranglers are on gas and how far they can actually go. So, hop right in because you’re in for a bumpy ride!

Jeep Wrangler Gas Mileage Explained

Jeep Wrangler Gas Mileage

If off road adventures are your thing, then it’s best to stay prepared. Yeah, there’s always the fuel economy factor.

  •       On the highway, a gas mileage of 24 mpg is expected.
  •       While you’re on the city, it’s unwise to expect more than 22 mpg.
  •       And of course, the expected combined mileage is 23 mpg.

With that said, here’s a vital piece of information. Just about any Jeep Wrangler’s mileage is dependent on the engine and the transmission. You might want to compare these powertrains if you’ll be putting a premium on fuel economy.

2.0-liter turbo four-cylinder: This will allow your Jeep Wrangler 24 mpg on the highway, 22 mpg in the city, and 23 mpg combined.

3.6-liter V-6: With this one, your Jeep Wrangler will offer 24 mpg on the highway, 20 mpg in the city, and 21 mpg in combined situations.

3.6-liter V-6 and manual transmission: Finally, with the help of this, you can go up to 25 mpg on the highway, 17 mpg in the city, and 20 mpg combined.

I’d suggest you to make the final decision on the balance between power and mileage. Well, the rest of it depends on you.

Issues that Affect the Jeep Wrangler’s Gas Mileage

Before understanding the “Why”, let’s first discover the “Why nots.” This section, in particular should give you a general idea on what limits the Jeep Wrangler’s gas mileage. A gas mileage around or below 20 MPG? Well, these factors elaborate clearly on the reason why many users get disappointed.


The angular shape that makes the Jeep Wrangler so distinct is the very reason they fall short in terms of aerodynamics. Its rather square-shaped build reduces the airflow around its body drastically. So, predisposal to wind resistance is a given. And there you have it, more fuel burnt…

Air Conditioning

The more comfort you get on the inside, the less mileage you get for the gas you buy, sadly. Sounds surreal, but yes, it’s true. People really do want to be as far away from humid and dry weather as much as possible. And that’s exactly why the Jeep wrangler takes them to the gas station as much as possible.


If you tend to go off-road a lot and don’t take proper care of your Jeep Wrangler afterwards, you’ll be facing some issues. Dirt really does tend to accumulate where the air is supposed to flow in and out of the engine. This makes the Wrangler burn more gas. Not to mention poor acceleration.

Engine Oil

The type of engine oil you actually use can have an impact on the gas mileage. Doing it right can actually increase the mileage up to twelve percent. Don’t hold back on your motor oil expenses. You might end up regretting it.

Driver Behavior

Driving recklessly, revving up your engine too often, excessive idling, jackrabbit starts, and of course, speeding can really burn fuel fast and should be avoided if possible. I mean, hey, it’s already as hard as it is now, isn’t it?


It might be difficult for some to realize that the fact that the Jeep Wrangler is a gas gobbler is something that they love the most. It’s literally built for running on higher revs and a much heavier chassis.

Because it’s a 4WD vehicle, it can move from the front axle. Making it an off-roading king with more weight and drag.

Octane Rating

You can measure how much fuel your engine burns based on the fuel reduction-to-additive ratio. It’s called the Octane rating. The higher the Octane rating, the lesser burning of fuel and the more the mileage.


Do you like mods? Well, you won’t like your gas bills then. Mods can have a real impact on your Wrangler’s fuel efficiency. Adding stuff like 35-inch tires, steel wheels, and so on. Yeah, I know customizing vehicles can be fun.

If you have to do it, do it right. Remember that increased airflow and heavier tires can even improve mileage.

Tire Inflation

Rocks, deep snow, mud bogs, and sand dunes demand airing down your tires. Once you do that, the rolling of the tires will require more resistance and thus create the need for more energy.

There are some cases where airing down your tires can’t be avoided. Make sure to do it on the requirement of the topography. On the basis of the recommendations of NAPA, you should release 10 psi on rocky terrain and 5 psi on dirt per tire.


The weight adds to the overall fuel efficiency as well. I’m not only talking about the stock form of the vehicle. Adding mods makes it worse for your gas mileage.

Tricks to Squeeze Out Some Performance

Here are a nice set of tips that’ll help you improve your gas mileage.

Early Refueling

Try to refuel as early as possible when the gas is still dense. This will really help out getting the last drops of performance.

Don’t Be a Spend Thrift

Don’t go for an upgrade unless it’s absolutely necessary. Also, try not to overload the wrangler. The ski racks don’t have to carry stuff the whole year round.

Some Smart Technicalities

Things like prolonged idling is a bad idea. So, try to avoid donut breaks as much as possible. Plus, you’ll also want to give the air conditioner a break. It doesn’t have to stay on all the time. Trust me, this’ll be an absolute lifesaver.

Observe the Necessities

The state of the brakes can actually affect the mileage. It’s a good idea to keep them in check as much as possible. Also, do periodic checks of failing parts, and don’t falter when repairs are needed.

Useful Knowledge Helps

Be consistent about quality motor oil and fuel types and avoid heavy acceleration. 40-45 mph is a good point to stay in. It’s wise to go for higher gear which covers the exact speed you’re travelling at. Plus, avoid heavy acceleration. 40-45 mph is a good point to stay in.

Are Jeep Wranglers Good on Gas?

Well, to keep it short, no. But there are ways you can enhance the mileage. Plus, you can try to actually avoid the stuff that’ll increase the overall fuel consumption.

Final Words

As I’ve said before, people don’t usually utter Jeep Wranglers and fuel economy in the same sentence. However, I hope I was able to give you a clear idea of the concept. You should have gotten the answer that you were looking for.

Closing it up for now, then. Goodbye.
