How to check your 2016 Jeep Wrangler’s gas tank size

Still unsure which size gas tank your 2016 Jeep Wrangler is hiding within? The easiest way to figure it out is to completely drain your gas tank and then fill it up to the top. 
This might not give you an exact measurement, but considering the nearly four-gallon difference between the Wrangler’s two tank sizes, it will be close enough to tell you if your tank’s fuel capacity is 18.6 gallons or 22.5 gallons. 

How to save on fuel costs in a Jeep Wrangler

Using regular gasoline, a 2016 Jeep Wrangler equipped with four-wheel drive is rated for about 18 mpg combined city/highway. Wranglers equipped with two-wheel drive will have a fuel economy rating closer to 16 mpg combined.
That’s not a great fuel economy for the everyday driver—but owning a Jeep Wrangler doesn’t have to be a detriment to your bank account. Here are some tips and tricks on how you can conserve gas and save money at the pump: 
  • Keep up with your
    car maintenance schedule
    . Avoid letting ordinary wear and tear get out of hand to keep your Wrangler’s fuel economy stable. 
  • Drive carefully. Try not to slam on the brakes or the gas to keep your fuel consumption even and as low as possible. 
  • Avoid idling, especially in cold weather. Idling eats up gas for no good reason, so drive your SUV gently to warm it up on those chilly winter mornings instead of letting it run in your driveway.
