How to check your 2018 Jeep Wrangler’s gas tank size
If you’re curious about how big your Jeep Wrangler’s gas tank is but can’t
find your car owner's manual
to access the information, don’t hit the alarm yet—we’ve got your back. Here are some quick tips and tricks to determine how much fuel your Wrangler’s tank can accommodate.Measure the gas tank
If you want a quick and simple way to determine your gas tank size, you can do it manually—with a pen and paper. Measure the length, width, and height of your engine and multiply them together. Once you have a result, divide that number by 231 (the number of cubic inches in a gallon) and you’ll have your engine’s fuel capacity—no complex math involved!
Pretty simple, right?
Check your owner’s manual
All Jeep Wranglers come with an owner’s manual that details everything you need to know about owning and operating your Wrangler—including the gas tank capacity. If you’re unsure where to look, flip to the index and search for “fuel tank capacity” or any similar phrase to determine the capacity of your vehicle’s tank capacity.
Online copies are sometimes available if you don’t have a physical copy of your manual, so an internet search for the “2018 Jeep Wrangler vehicle manual” might return one.
Drive till empty, then fill it up
If you like to play with fire and you’re in desperate need of a backup plan to determine your gas tank capacity, there’s one final way to get an estimate—start the engine, put the pedal down, and drive until the fuel gauge hits “E.” When it’s time to fill up your tank, you’ll have a rough idea of how much gas is required from empty.
While this method won’t give you an exact number like measuring or your vehicle manual will, it does give you an idea of how much fuel it holds. But don’t drive empty for too long!
How to save on fuel costs in a Jeep Wrangler
The Jeep Wrangler is known for fun, not fuel efficiency—which means finding alternative ways to reduce fuel usage is important if you’re not looking to shell your entire paycheck over to the oil companies.
Despite the different engine sizes and power, the 3.6-liter V-6 engine and the 2.0-liter turbocharged four-cylinder have similar fuel economies. They get an estimated 18/23 mpg city/highway and 22/24 mpg city/highway, respectively.
But while the Wrangler Hybrid, the

, wasn’t available in the 2018 model year, there are some other tips you can follow to boost those fuel economy ratings further and save you money at the pump:- Follow a regularmaintenance schedule. Tire pressure, brake quality, transmission, and wheel alignment are all factors that influence fuel economy. If you don’t want to burn through gas, ensure you’re keeping your Wrangler well-maintained.
- Drive conservatively. Stick to the speed limit and accelerate slowly. Hard acceleration and speeding will burn through gas like nobody’s business. If you’re driving on highways, flick on cruise control to maintain a constant speed.
- Avoid idling. Idling is one of the quickest ways to burn your gas tank, so avoid it whenever possible. If you need your car to warm up, drive gently and let the engine warm up as your drive.
- Lighten the load. While your Wrangler can fit a fair bit of cargo and is capable of towing, heavier loads mean a heavier drive—and more gas burned. If you don’t need the unnecessary weight, remove it to help reduce fuel consumption.
