, has a guide to the 2022 Grand Cherokee gas tank size. 

How big is the gas tank on a 2022 Jeep Grand Cherokee?

Your 2022 Jeep Grand Cherokee will either have a 23-gallon or a 19-gallon gas tank. The size of your tank depends on whether you have a conventional trim of the Grand Cherokee or a 4xe trim.
The standard 2022 Jeep Grand Cherokee comes in seven trim levels, all of which have a 23-gallon gas tank:
  • Laredo
    : $40,120 starting MSRP
  • Altitude: $45,225 starting MSRP
  • Limited
    : $46,440 starting MSRP
  • Trailhawk
    : $56,030 starting MSRP
  • Overland
    : $56,035 starting MSRP
  • Summit
    : $60,095 starting MSRP
  • Summit Reserve: $66,575 starting MSRP
The 2022 Grand Cherokee release also includes the Grand Cherokee 4xe, Jeep’s plug-in hybrid EV (PHEV) version of the Grand Cherokee, which delivers a whopping 56 combined mpg, a hugely impressive fuel economy for such a large car. The five trim levels of the Grand Cherokee 4xe all come with a 19-gallon gas tank.

How to check your 2022 Jeep Grand Cherokee’s gas tank size

If you don’t want to take our word for it, you can check your 2022 Jeep Grand Cherokee’s gas tank size yourself! Here are a few ways to do that on your own:

Measure the gas tank

Whip out your measuring tape and measure away! Just multiply the width, length, and height—in inches—of your gas tank together. Then divide that number by 231, the number of cubic inches in a gallon. The resulting number will be the size, in gallons, of your gas tank. 

Check your owner’s manual

Look for the phrases “gas tank capacity” or “fuel tank capacity” in your ‘22 Grand Cherokee’s owner’s manual. 

Drive till empty, then fill it up

The least accurate—but perhaps most efficient—way to gauge your gas tank’s size is to drive until the gas tank is empty. Then, when you fill up your tank to full, you’ll have an estimate of your fuel tank’s capacity.

How to save on fuel costs in a Jeep Grand Cherokee

Looking to save a few (or more than a few) dollars a month on gas costs for your 2022 Jeep Grand Cherokee? Here are some of our favorite tips. 
  • To warm up your engine, just drive slowly—don’t idle. It’s a great idea to let your engine warm up before you drive with normal speed and acceleration, but you can cut down on wasting fuel by simply driving slowly and gently (less than 2,000 RPM) until your engine reaches normal operating temperature. 
  • Keep up with your Grand Cherokee’s maintenance. Oil changes, tire rotations, filling your tires with air—it all adds up and has a big impact on your engine’s performance. Skipping maintenance can dramatically decrease your engine’s fuel efficiency.
  • Drive gently. Not only do driving habits like slow acceleration and driving the speed limit keep you safe—they also keep you from wasting unnecessary gas.
