What is the Jeep Wrangler Gas Tank Size? On a 2021 Jeep Wrangler, the gas tank can hold 21.5 gallons of gasoline. Jeep Wrangler models for 2018 and 2020 have the same capacity. This amount is average since Jeep Wrangler models differ in their tank capacity.
Jeep Wranglers excel in ruggedness and capability, making them popular off-road vehicles. However, many people don’t know that the Wrangler’s fuel tank is also relatively small.
In this post, we’ll examine how big the Jeep Wrangler gas tank size is and what factors affect it. So let’s get started.
What Type Of Gas Does The Jeep Wrangler Take?
The Jeep Wrangler has a minimum gas octane rating of 87 on regular unleaded gasoline. Depending on the engine type, Jeep recommends the following types of fuel for newer Wranglers:
3.6-L V6 engine: Regular unleaded gasoline
2.0-L turbocharged four-cylinder engine: Premium unleaded gasoline
6.4-L V8 engine: Regular unleaded gasoline
3.0-L turbodiesel V6 engine: Diesel
What Is The Jeep Wrangler’s Gas Mileage?
The 2023 Jeep Wrangler receives the following EPA ratings based on powertrain:
3.6-L V6 engine: 17 mpg city/25 mpg highway/23 mpg combined
2.0-L turbocharged four-cylinder: 21 mpg city/24 mpg highway/22 mpg combined
6.4-L V8 engine: 13 mpg city/17 mpg highway/14 mpg combined
3.0-L turbodiesel V6 engine: 21 mpg city/26 mpg highway/23 mpg combined
Through its 20+ year production run, the Jeep Wrangler has steadily improved its gas mileage. Most standard models before 2020 got 16 to 19 MPG combined, while older models rarely got more than 20 MPG.
What are the Factors Affecting Jeep Wrangler Gas Tank Size?
It is essential to consider several factors when determining the gas tank size of a Jeep Wrangler. Among these factors are the trim level, the engine type, the model year, and any aftermarket modifications.
1. Trim Level
The gas tank size in a Jeep Wrangler can vary depending on its trim level. Sport models typically have a smaller gas tank than Rubicon and Sahara models. The Rubicon and Sahara models need a larger gas tank because they are designed for off-road use and longer trips.
2. Engine Type
A Jeep Wrangler’s gas tank size will also differ depending on the engine type. For example, a Jeep Wrangler powered by a V6 engine might have a larger gas tank than a four-cylinder engine. As a result, the V6 engine consumes more fuel and is more powerful.
3. Model Year
Jeep Wrangler gas tanks can also vary according to the model year. Newer Jeep Wrangler models have larger gas tanks than older Jeep Wrangler models. This is because newer models use more advanced technology and require more fuel.
4. Aftermarket Modifications
In addition, aftermarket modifications can also affect the size of the gas tank on a Jeep Wrangler. A larger fuel tank, for instance, will result in a larger gas tank than the stock one. The gas tank size will also depend on modifications such as larger tires or a lift kit.
How To Check Your Jeep Wrangler Gas Tank Size?
In case you’re still unsure, you can use a few different methods to determine the size of your Wrangler’s gas tank.
1. Gas tank measurement
Using a measuring stick is the method they used back in caveman times.
A fuel tank holds gallons of gasoline when its length, width, and height are measured in inches, multiplied, and divided by 231, which is the number of cubic inches in a gallon.
The total fuel capacity of a tank measuring 13 inches wide, 15 inches high, and 35 inches long is 6,825 cubic inches. That will determine how many gallons fit into your tank – in this case, 29.55 gallons. Divide that number by 231, and you’ll get how many gallons fit into your tank.
2. Read your owner’s manual to find out more
You can easily find your vehicle’s gas tank capacity in your owner’s manual. The manual’s table of contents or index will contain information like “fuel capacity” or “fuel tank.”.
3. Once it’s empty, fill it up
If you drive your Wrangler until the fuel gauge reaches “E”, you can estimate its fuel capacity. Fill up your Jeep’s gas tank and record the amount of gallons you filled it with.
It is important not to run out of fuel while driving if you use this method. Running out of gas can cause your engine to stall off-road or at high speeds, which can be devastating.
What Are The Advantages Of Jeep Wrangler’s Large Tank?
Jeep Wranglers with a large tank have the following benefits and drawbacks:
1. Range is better
81 gallons of gas capacity makes travelling on any road effortless without worrying about fuel draining. You get the best range from your Jeep Wrangler if you fill your fuel tank to the top.
2. Refilling is less frequent
With the Jeep Wrangler’s gas tank size, one-time fill-ups will benefit most. One 17.5-gallon tank can provide a driving range of up to 500 miles. Keep it as a backup before you rush for your next refill because it has a retention capacity of almost 15%.
3. User-friendly
Gas tanks on Jeep Wranglers have the advantage of being relatively simple to use. The 2021 Jeep Wrangler is the most efficient model for fuel retention capacity. A fuel tank can hold 21.5 gallons, enough for a trip of more than 590 miles. You can save time and money by using this fuel storage.
What Are The Disadvantages Of Jeep Wrangler’s Gas Tank Size?
The Jeep Wrangler’s huge gas tank has many benefits, but it also has a few drawbacks. Here are a few:
1. Heavy tanks
Your Jeep Wrangler’s efficiency increases when you fill the tank with more fuel. Yes, that’s correct! As a result, you must put more pressure on your engine, especially if you are driving uphill. The vehicle appears heavier to operate on uphill drives.
2. Low fuel efficiency
It is evident that the more weight you have on your Wrangler, the less fuel-efficient it will be. Therefore, the weight you can carry while driving is always limited. If you drive more weight than you should, your fuel will run out even faster. You become tired and indecisive while driving due to this weight.
3. Expensive refills
It depends on the model of your Jeep Wrangler and whether you need to refill it. Models with lighter weights may not require frequent refills, while models with heavier weights may. Some models are fuel efficient, such as the 2021 Jeep Wrangler, one of the best.
A few of these non-fuel-efficient Jeep Wrangler models include the Jeep Wrangler Rubicon 392 and the PHHEV Jeep Wrangler4xe, which offer only 13-49 MPEGs.
What Size Of The Gas Tank For The 2019 to 2021 Model Of Jeep Wrangler?
As of the 2019-2021 models, Jeep Wrangler gas tanks hold 21.6 gallons. Drivers will be able to travel approximately 300 miles on this fuel. There are differences between model years and engine types in the Wrangler’s gas mileage. According to EPA estimates, the 2020 Jeep Wrangler gets 17 mpg in the city and 23 mpg on the highway with the 3.6-liter V6 engine.
On the other hand, the 2019 Jeep Wrangler gets 18 MPG in the city and 23 MPG on the highway with the same engine. EPA estimates 23 MPG in the city and 31 MPG on the highway for the 2021 Jeep Wrangler 4-door with a 2.0L I4 Turbo engine and 8-speed automatic transmission.
What Size Of The Gas Tank For The 2011 to 2018 Jeep Wrangler Model?
The Jeep Wrangler gas tank comes in various sizes, depending on the year and model. Tank capacity ranges from 22.5 gallons to 27.5 gallons for the 2011 to 2018 models. It provides plenty of fuel without being too heavy, which is great for off-roading and long drives.

How Do You Choose the Right Size Gas Tank for Your Jeep Wrangler?
There are several factors to consider when choosing the right gas tank size for your Jeep Wrangler:
1. Frequency and habits of driving:
If you typically drive your Jeep Wrangler, consider how much and how often you do so. To avoid frequent gas station stops, a larger gas tank may be more appropriate if you frequently go on long off-road trips or drive your Jeep daily.
2. Requirements for off-road driving:
Jeep adventures often involve off-roading, so make sure the size of your gas tank suits your off-road excursions. It may be necessary to have a larger gas tank in remote and rugged terrains to navigate effectively.

You may have to reduce your storage space if you increase the size of your gas tank. You will have less room for other essential supplies and equipment if your gas tank is large.
Aftermarket Options To Increase Gas Tank Capacity
You can increase your Jeep Wrangler’s gas tank capacity with aftermarket options if you often refuel your vehicle or desire a more extended range. These aftermarket fuel tanks for Jeep Wranglers ensure a seamless fit and proper functionality. You can enjoy longer trips without frequent refuelling stops by increasing the capacity of your gas tank.

Do Gas Tank Size and Capacity Impact Fuel Efficiency?
The size and capacity of gas tanks do not directly affect fuel efficiency except that they add mass to the vehicle.
A larger fuel tank means more weight is added to the vehicle; when it’s fuel, you have a significant weight burden.
However, it is a natural phenomenon, and every vehicle is designed accordingly.
Therefore, you shouldn’t be too bothered by it. The bigger the gas tank on your Jeep, the greater its maximum driving range.
