How to check your 2004 Jeep Grand Cherokee’s gas tank size

Every 2004 Grand Cherokee has a gas tank with a fuel capacity of 20.5 gallons—but don’t take our word for it! Here are a few ways to check the size of your gas tank yourself.

Measure the gas tank

Have a measuring tape and calculator? You can find the size of your fuel tank with some easy math. Here’s how:
  • Get under your car and locate its gas tank.
  • Measure the width, length, and height of the tank, then multiply those numbers together.
  • Once you get the result, just divide by 231 (that’s the number of cubic inches in a gallon) and you’ll have your fuel tank’s gas capacity.

Check your owner’s manual

The most straightforward way you can check your gas capacity is by simply looking it up in your owner’s manual. Most manuals have a “specifications” page that includes information on your gas tank, but you can also check the table of contents for a “gas tank” or “fuel tank” listing.

Drive till empty, then fill it up

If you don’t have your owner’s manual on hand and don’t want to crawl under your car, you can go with a less scientific approach. If you drive your car until the fuel gauge reads “E” and then go to the gas station to fill it up again, you can simply watch the meter on the gas pump to see how many gallons of gas it took to fill your tank. 

How to save on fuel costs with a 2004 Jeep Grand Cherokee

The Environmental Protection Agency (EPA) rates the 2004 Grand Cherokee for either 15 or 16 miles per gallon, depending on its engine type and drivetrain. With gas prices reaching all-time highs in 2022, even taking small steps to conserve gas can make a big difference in your budget.
If you want to cut down on your fuel costs, here are a few tips:
  • Don’t neglect
    basic maintenance
    . Making sure your
    oil changes
    , engine
    tune-ups
    , and wheel alignments are done on time can reduce your car’s fuel consumption.
  • Drive carefully. The more you do things like speed up quickly and slam on your brakes, the more often you’ll need to visit the gas station.
  • Don’t idle. Shut down your car’s engine whenever you’re parked—even if it’s only for a few minutes. Leaving the engine running when you’re not driving uses fuel unnecessarily.
