However, the two-door models have a 17.5 holding capacity. A Jeep Wrangler’s gas tank can hold 17.5 gallons in the two-door option. However, newer two-door options may hold about 18.5 gallons of fuel.
How Often To Fill up the Gasoline Tank in Your Jeep Wrangler
It would be best to fill up your Wrangler gas tank once it is half empty. However, the frequency you would need to fill up your tank depends on how often you drive it and your driving habits. Driving your Wrangler daily means you’ll have to fill up your tank every three to five days. The more you go, the more you need to fill up often, and the less you go, the less you need to fill up.
Your driving habit also contributes to how often you must stop at the gas station. If you idle a lot, step on the brakes or accelerate suddenly, you’ll likely have to fill up your tank often.
At what point does the refill light turn on in a Wrangler? The refill light on a Wrangler will come on when your tank is down to about three gallons of fuel or less. When this is the case, you’ll notice a yellow light with a fuel pump icon on your vehicle’s dashboard. Once you see this light, it indicates that you need to stop at the gas station.
– Jeep Wrangler’s Average Gas Mileage
The average gas mileage is dependent on the model of the Wrangler. However, most Wranglers have a decent gas mileage of 24 miles/gallon (MPG) on the highway, 17 to 23 MPG within the city, and 19 to 25 combined MPG. For instance, the 2021 Jeep Wrangler 4dr 4xe has a mileage of 49 combined miles/gallon equivalent (MPGe) and a 22-mile all-electric + gas range. All of this makes the Wrangler 4xe the most fuel-efficient hybrid SUV.
Which Jeep uses the least amount of gas? The 2022 Regenade uses the least gas because it features a turbocharged 1.3-liter four-cylinder engine with 25 MPG combined. It is followed closely by the Jeep Wrangler 4xe Plug-in Hybrid, which has 49 combined MPGe.
– Why Jeeps Have Poor Mileage
Jeeps generally lack good mileage because of their heavy weight and aerodynamics. A Wrangler weighs between 3,948 and 5,900 pounds, meaning they are heavy. A heavy Jeep will have less fuel mileage than a regular passenger car. Various features like doors, hoods, wench, and hinges also contribute to the Wrangler’s heavy weight, significantly reducing mileage.
The Jeep’s aerodynamic design also contributes to its poor mileage. Aerodynamics is concerned with how air moves through things. Jeeps have more difficulty moving through the air because of their large size. Your Jeep will use more gas when speeding on the highway because its size doesn’t allow for a seamless aerodynamic movement.
Another reason why most Jeeps have poor mileage is because of the extra load added to them. Jeeps are already heavy vehicles, so excess loads or add-on features will only affect aerodynamics and reduce fuel mileage. The gas mileage will undoubtedly be affected by each extra pound or weight added to the Jeep.
The Wrangler has inconsistent mileage because of its heavy weight, boxy shape, and aerodynamic properties. Extra add-ons also increase this weight and affect its aerodynamics, causing it to consume more fuel and have inconsistent mileage.
– Add-ons That Negatively Impact Fuel Mileage
Add-ons can negatively impact a car’s mileage even though they beautify your car and make it more functional. One common add-on that affects mileage the most is the High Lift.
Although the high lift has the advantage of increasing ground clearance and allowing for large tires suited for off-roading, it also has a disadvantage. Wranglers are heavy vehicles, so a High Lift significantly increases their weight and affects their aerodynamics.
Other add-on features that affect fuel mileage are light bars, large wheels, a big bumper, and wenches. All of these decrease the aerodynamics of your Wrangler, making it difficult for air to pass over and through your vehicle.
– A Diesel Option of the Wrangler
Jeep makes a diesel option for the Wrangler, which is the 2021 Jeep Wrangler EcoDiesel model. The EcoDiesel Jeep has an engine of 3.0 liters V6 and only comes in four-door models.
It also comes with an 8-speed automatic transmission, making it a mighty Jeep. Another impressive feature of the EcoDiesel Jeep is its massive torque of 442 pounds and an impressive 240 horsepower output.
– Driving a Jeep Without Gas
Driving a Jeep on an empty tank is not safe, as it can damage your engine and affect the vehicle’s performance. Going on an empty tank will cause the engine to overwork itself, leading to overheating.
Other essential components like the catalytic converter and your fuel pump could also be affected. Hence, driving a Jeep with an empty tank is not recommended.
How Can You Check Your 2022 Jeep Wrangler’s Tank Size Gallons?
You can check your 2022 Jeep Wrangler’s tank size gallons and gas tank capacity by measuring the tank. You could also look up the gas tank size in your owner’s manual. Another way you can know your gas tank size is by emptying and refilling the tank.
– Measure the Tank Size
Measuring the tank is one of the quickest ways to determine the exact petrol capacity of your 2022 Wrangler. You need to get under your car with a measuring tape and get the fuel tank’s length, width, and height. Then multiply all the numbers to get a total.
Once you get that, divide the total by 231, which is the value of cubic inches in a gallon of gasoline. The final answer you get is the size of your gasoline tank.
– Check Your Car’s Owner’s Manual
Checking your owner’s manual is the easiest and fastest way to know the exact size of your petrol tank. All you need to do is observe the table of contents and find the “Fuel Capacity” column. Note the page number, go to the page, and you’ll find the exact size of your 2022 Wrangler petrol capacity listed there.
You don’t need to worry if you’ve misplaced your owner’s manual or never had one. You can look up this information on Google or download the manual in PDF format from the manufacturer’s website.
– Empty and Refill the Tank
You can empty and refill your gasoline tank if you want to know your gas tank size. However, this is tedious because it requires you to drive until your gasoline tank is empty. Your tank has to be empty to get its correct size, which can be hazardous to your engine and even your fuel pump.
Still, it is a sure method of getting the exact size of your tank. The number of gallons you pump into it after emptying it is the number of gallons it can hold.
How Can You Make the Gasoline Gallons of a Wrangler More Efficient?
You can make the gasoline gallons of a Jeep Wrangler more efficient by using high-quality gasoline and periodically inspecting your tire pressure. You can also do this by maintaining speed and avoiding overloading the Jeep, as well as limiting idling and fixing or replacing the throttle system.
– Only Use the Best Gasoline
One way to make your gasoline tank more efficient is by using only the highest-quality gas. Using premium gasoline makes all the difference, especially if you own a high-performance vehicle like a Wrangler. The highest-quality gas makes it easy for you to hit the highest horsepower in the Jeep Wrangler without the engine knocking.
Also, a premium gas will increase your gasoline tank efficiency and provide better mileage. It will also reduce the rate of harmful fuel emissions.
– Take Fewer Short Trips
Quick trips consume as much fuel as long ones, contrary to what you might think. Embarking on short trips means stopping and starting the car at intervals, which can be bad for your engine. While this can seem like nothing, it could be a big deal in cold seasons, where it takes some time for your engine to warm up properly.
If you continue making short trips, it could be unsuitable for the engine because it may not be able to warm up properly before it is turned off again. It would be best if you embarked on longer trips because this will give your engine time to warm up to a temperature that’s best for fuel efficiency.
– Inspect the Tire Pressure Often
Inspecting your tire pressure regularly is another great way of improving gas tank efficiency. The tension in your Wrangler tires will surely drop over time. Although many vehicles now come with a pressure sensor, inspecting your tires helps you figure out other defects besides a pressure drop. If you ride with an inflated tire, it’ll reduce fuel efficiency by two percent.
Aside from this, inflated tires increase rolling resistance, causing the engine to overwork itself. You’ll also discover that you have issues with braking and increased wear, especially on the edges of the tire.
– Activate the Cruise Control System
If you drive on a level, flat road, using cruise control will significantly improve your gasoline tank efficiency. A cruise control system is handy because it lets you set your vehicle at a constant speed. It ensures your car doesn’t supersede the set speed while allowing you to take your feet off the accelerator.
Since accelerating takes up more fuel, cruise control will improve gas efficiency and help you save on fuel costs. Besides, a cruise control system provides security for you and others in the vehicle because it lets you drive more safely.
– Avoid Unnecessary Fill-Ups
An overloaded Jeep will surely guzzle more fuel than usual. This is because the additional weight will make it harder for the Jeep to propel itself smoothly. The fuel economy is reduced with every extra weight added to your vehicle.
To improve tank efficiency, offload unnecessary items from your Jeep, both the trunk and the rooftop. If you must haul heavy items, you can use a utility trailer to reduce the load on your Jeep.
– Limit Idling
Unnecessary idling is one enemy of fuel. You should avoid idling if your goal is to optimize fuel efficiency. Idling, especially on high-performance vehicles like a Wrangler, takes up more for zero miles/gallon. Letting your Jeep idle for long periods causes a strain on the engine and is capable of causing damage.
When this happens, you have to deal with high fuel costs and higher maintenance costs for a damaged engine. Reducing idling will ensure fuel efficiency and protect your engine from overheating.
– Consider Changing the Tires
If you’ve used your tires for years, consider changing them. Even though your engine may still be intact, there will surely be a drop in tire pressure as time goes by. You don’t have to wait for the tires to wear out before you replace them.
If you’ve been using your tires for more than three years, changing them can significantly improve your gasoline tank efficiency. Also, having new tires will enhance your vehicle’s performance and guarantee a comfortable ride.
– Fix or Replace the Throttle System
The throttle system is an essential component of a vehicle. It regulates the fuel-air mixture that enters the engine, ensuring that both combust properly to power the car. Over time, your Jeep’s throttle system will have a dirt buildup. When this happens, you’ll notice a reduction in fuel efficiency, and your car will even start to idle roughly.
In this case, you’ll need to fix the throttle system by ridding it of debris with a rag and cleaner. If cleaning it doesn’t work, you’ll need to replace the throttle system to improve gas efficiency.
– Carry Out Routine Checks
You can make your Wrangler’s tank more efficient by carrying out a routine check on your Jeep. Make sure the engine is kept clean from debris and dirt. In the same way, check your spark plugs, fuel pumps and injectors, brake pads, transmission oil, and other essential Jeep components.
If you notice they are not working well, you should get a tune-up by replacing them immediately. Replace or top up your transmission oil where necessary, and carry out these checks every three to six months.
– Maintain Speed
Maintaining speed and driving within the speed limit is one of the more effective methods to increase tank efficiency. A Wrangler is only sometimes built for speed due to its heavy weight and aerodynamics, especially on the highway. Speeding and sudden bursts of acceleration take up more fuel.
Hence, you should adjust your driving habits to maintain speed and ensure you drive as gently as possible. If you can do this successfully, you’ll discover a significant improvement in your tank efficiency.
– Adjust Driving Habits
You can improve your 2022 Wrangler’s fuel economy by adjusting your driving habits where necessary. Gas price has continued to increase over the years, hence the growing need to save gas cost by all means possible. First of all, you need to drive as gently as possible if you want to ensure fuel efficiency. Ensure you maintain a steady speed when moving and avoid sudden bursts of acceleration.
Watch out for the amount of pressure you put on the accelerator when driving. The more force you use, the more gas is required to increase and maintain the speed. Similarly, you can save fuel costs with a 2022 Wrangler by avoiding sudden brakes. Unnecessary idling is another enemy of fuel efficiency.
You should turn off your Jeep’s engine if you’ll be idling for a long time to reduce fuel consumption. Reducing the weight of your Wrangler is another way to improve fuel economy. You should avoid frequent hauling of heavy items to save fuel costs because a loaded Jeep will require more fuel to operate seamlessly.
Finally, another aspect of good driving habits is inspecting your Jeep tires regularly to ensure they have the right amount of pressure to function correctly. A tire with reduced pressure increases strain on the Jeep’s engine since it has to work twice as hard to compensate for increased friction.
– Reduce Use of Air Conditioning System
You can get more miles out of your fuel by reducing your use of the air conditioning system. Every air conditioner consumes more gas than average, so you may need to cut down on it if you want to stretch your fuel. Another way you can get more miles out of your fuel is by ensuring the Jeep is well-maintained and running smoothly. If your spark plugs, brake pads, or tires aren’t in excellent working condition, make sure they are quickly fixed.
You should also check your fuel injectors to ensure that they are working correctly. If they do, you’ll find that your vehicle consumes less fuel. Driving sensibly is another way to get the most miles out of your fuel, especially when you maintain a consistent speed.
Top up or replace engine transmission oil whenever it’s on a low level or looks dirty. Also, inspect your car and fix every defective component to avoid overworking your engine.
