How to check your 2014 Jeep Wrangler’s gas tank size

If you want to double-check your 2014 Jeep Wrangler’s gas tank size yourself, there are a few methods you can follow to get the information. 

Measure the gas tank

You’ll need a tape measure and calculator to do this, but you can always measure the gas tank on your own. Use the measuring tape to get the dimensions of the width, length, and height of the gas tank. Multiply these measurements together and divide by 231 (the number of cubic inches in a gallon) to get the answer. 

Check your owner’s manual

Flip through your owner’s manual to a phrase like “fuel tank capacity” to find the information you need. 

Drive till empty, then fill it up

You can also take a riskier approach by driving until the fuel gauge hits “E” and then filling up. Your measurement won’t be exact, but you’ll get a general idea of the tank size. Use caution when employing this method—don’t run out of gas!

How to save on fuel costs in a Jeep Wrangler

The gas mileage on a 2014 Jeep Wrangler isn’t great at 17 mpg city and 21 mpg highway. Your combined mileage is 19 mpg, which surely motivates you to find some ways to save on fuel costs.
Try these tips to cut back on your costs at the pump:
  • Keep up with
    vehicle maintenance
    . If you let wear and tear carry on for too long, it’ll start to affect your fuel economy.
  • Drive on the road safely. Don’t accelerate quickly and drive a little slower to save on gas.
  • Do not idle your engine, particularly in cold weather. When it is cold out, it might be tempting to let your engine run to get the car nice and toasty, but this will waste your gas and lower your fuel economy.
