The 2015 Jeep Wrangler has just one engine configuration—a 3.6-liter V6—and one 6-speed manual drivetrain. Despite that simplicity, the 2015 model has 17 variations between its trim levels and special editions. But between all 17 model types, you’ll have one of just two gas tank sizes—a 22.5-gallon tank, or an 18.6-gallon tank.
Picking out the right Jeep Wrangler, with all its options and editions, can be a dizzying process, and if you’ve purchased a 2015 model that doesn’t have the owner’s manual with it, you might have missed the vehicle’s gas tank size. That’s why

With so much consistency across the 2015 Jeep Wrangler’s models, you may be wondering why the brand bothered with two sizes of gas tanks. There’s actually a pretty simple explanation—some Jeep Wranglers are just bigger than others.
The Unlimited edition of any Wrangler trim is going to be a four-door version of the SUV, which usually has just two doors. That means they’re bigger, longer, and heavier, and will need more gas in the tank to achieve the same range as the smaller Wranglers. Also, the larger size means there’s just more room for a bigger gas tank.
To help clarify what models got which tank, here’s a table of each trim level and its gas tank size:

Rubicon Hard Rock | 18.6 gallons |

If you’re not convinced by these numbers, you can always check your 2015 Jeep Wrangler fuel tank capacity for yourself. Here are a few methods that will work:
Measure the gas tank
Gather a measuring tape, something to write with, some paper, and a calculator. Then, get underneath your Jeep and jot down the gas tank’s width, length, and height in inches. Multiply these measurements together, and then divide the total by 231—the number of cubic inches per gallon—to find the tank’s fuel capacity.
Check your owner’s manual
Checking your owner’s manual only works if you can find it. Luckily, if the hard copy is lost, you can find a

pretty easily online. Drive till empty, then fill it up
It’s a little rudimentary, but it’ll work. You can drive your Jeep Wrangler until the fuel indicator is down to the E line, and then fill up the gas tank. The number of gallons you have to buy should tell you the total capacity your Jeep can hold.
How to save on fuel costs in a Jeep Wrangler
We know that people don’t buy Jeep Wranglers with fuel efficiency at the forefront of the mind. It’s a recreational vehicle made for off-roading and exploration. That said, if your Wrangler is doing double-duty as a daily driver, you can apply some techniques to save on fuel expenses. Here are our recommendations:
- Keep a goodmaintenance schedule. Staying on top of regularoil changesand tire rotations will help your Wrangler achieve its maximum fuel economy.
- Drive slowly when you can. Staying at the speed limit and coasting to a stop instead of braking are easy ways to cut gas consumption.
- Don’t sit idle. If you’ve parked, go ahead and shut off the engine. Sitting idle will just waste gas.
