How big is the gas tank on a Fiat 500?

The gas tank on a 2022 Fiat 500 is 12.7 gallons. But many previous model years (2012 to 2019) have a smaller gas tank size of 10.5 gallons.  
As you can see below, the available trims for the Fiat 500 do not impact its gas tank size:
  • Pop X AWD: 12.7 gallons
  • Sport X AWD: 12.7 gallons
  • Trekking X AWD: 12.7 gallons
  • Yacht Club X Capri X AWD: 12.7 gallons
While trim levels might not make a difference, choosing various powertrains and drivetrains can change a vehicle’s gas tank size and, subsequently, its fuel economy. 

How to check your 2022 Fiat 500’s gas tank size

If you’d like to measure yourself, these three methods will tell you the gas tank size of your 2022 Fiat 500. None of them require a lot of car knowledge, which is good news for the average driver.  

Measure the tank

You can use a measuring tape and a calculator to measure the gas tank. Simply follow these three steps:
  • Measure your tank’s dimensions: height, width, and length 
  • Multiply these numbers
  • Divide that number by 231 to convert the total from cubic inches to gallons

Read your owner’s manual

Go to the index in your owner’s manual and search for “fuel tank capacity” or something close to that, and you should find the exact measurement.

Drive till empty, then fill it up

This one is easy but takes a bit of time and awareness. Drive your Fiat 500 until your gas gauge hits “E.” Then, head straight to a gas station to fill your tank. This will tell you approximately how many gallons of fuel your vehicle requires. 

How to save on fuel costs for a 2022 Fiat 500

Your vehicle’s gas tank size doesn’t have to be the only determining factor for how much you’ll pay for gas every week. Here are three ways to shrink your fuel budget:
  • Adhere to the recommended maintenance intervals to improve your fuel economy or to at least ensure it doesn’t worsen.
  • Idling wastes fuel and is bad for the environment. Resist the urge to idle your vehicle when it’s just as easy to turn it off and then back on again. 
  • Driving carefully is good for your vehicle’s fuel economy and overall performance. Be extra cautious when accelerating and braking.
