How big is the gas tank on a Subaru Crosstrek?

The Subaru Crosstrek’s gas tank size varies by model year and powertrain. The 2022 model spans the complete range, however, with the hybrid model measuring 13.2 gallons of maximum fuel capacity and the standard gas engine measuring 16.6 gallons
Here’s a look at how the Crosstrek’s gas tank size varies by model year: 
  • 2013 Subaru XV Crosstrek: 15.9 gallons 
  • 2014 to 2015 Subaru XV Crosstrek: 13.7 gallons to 15.9 gallons
  • 2016 Subaru Crosstrek: 13.7 gallons to 15.9 gallons
  • 2017 Subaru Crosstrek: 15.9 gallons 
  • 2018 Subaru Crosstrek: 16.6 gallons 
  • 2019 to 2023 Subaru Crosstrek: 13.2 gallons to 16.6 gallons 
The main difference in gas tank size boils down to whether your Crosstrek has a hybrid powertrain or not. The 2013 Subaru XV Crosstrek and the 2017 and 2018 Subaru Crosstrek models don’t have a hybrid option available, so their gas tank size remains uniform across all trims. 
Every other model year does offer a hybrid option, however, which is naturally designed to hold (and require) less fuel. Consequently, if your Crosstrek is a hybrid, its gas tank size will consistently make up for the lower fuel capacity for its model year. 

How to check your Subaru Crosstrek’s gas tank size

If you’re ever second-guessing the fuel capacity numbers you see online, there are ways you can check your Subaru Crosstrek’s gas tank size on your own. 

Measure the gas tank

With a measuring tape and calculator handy, you can actually use your Crosstrek’s gas tank measurements to get an idea of its fuel tank capacity. All you have to do is multiply the length, width, and height measurements together, then divide by 231, which is the number of cubic inches in a gallon. 

Check your owner’s manual

The easiest and most official way to verify measurements, of course, is to consult your Crosstrek’s owner’s manual. The gas tank size should be listed under “fuel tank capacity” or similar phrasing. 

Drive till empty, then fill it up

A riskier method to determine your Crosstrek’s fuel capacity is to let your fuel gauge hit empty, then see how much gas it takes to fill up. You won’t get the most accurate measurement this way, but it will give you a pretty solid idea of your gas tank’s general size. Just don’t drive around on “E” for too long!

How to save on fuel costs in a Subaru Crosstrek

Opting for one of the Subaru Crosstrek’s hybrid or plug-in hybrid configurations can save you a lot of money at the pump. In fact, the 2023 Crosstrek’s plug-in hybrid receives an EPA-estimated 36/35/35 mpg city/highway/combined
If you go for the flat-4 gas engine with CVT automatic transmission, you’ll still make fairly decent mileage for the crossover SUV segment at 28/33/30 mpg city/highway/combined. But there are a few ways you can save a little extra on fuel, too:  
  • Keep up a
    regular maintenance routine
    . Skipping out on your Crosstrek’s maintenance can lead to contamination buildup in your fuel systems, reducing fuel efficiency and potentially causing long-term harm. 
  • Ease up on acceleration. The less you press on the gas pedal, the more gas you conserve. Therefore, if you can glide rather than accelerate, you’ll enjoy lower fuel costs.
  • Try not to idle. As tempting as it is to remote start your Crosstrek to warm it up on cold winter mornings, doing so uses a lot of gas. To improve your fuel efficiency, avoid idling as much as possible.
