How to check your 2021 Subaru Crosstrek gas tank size

If you still haven’t the foggiest idea of how many gallons your 2021 Crosstrek slurps up, not to worry—that’s why Jerry is here. There are a few easy ways to determine your gas tank size. Within no time, you’ll be pumping gas like nobody’s business!

Measure the gas tank

If you want to measure the size of your Crosstrek’s gas tank, just grab your trustymeasuring tape and a calculator—we prefer anything made by Texas Instruments,but go ahead, use your phone.
Now, simply multiply your gas tank’s height, length, and width,and then divide that number by 231 (the number of cubic inches in a gallon). And there you have it—you’re a gas tank size-calculating dynamo.

Check your owner’s manual

No, that’s not your bruised and battered copy of Treasure Islandit's your 2021 Subaru Crosstrek owner’s manual, languishing all by its lonesome in your glove box. Well, no longer. Get your mitts on it and flip through the index, looking for a phrase such as “fuel tank capacity.” Once you find it, you’ll be in business.

Drive till empty, then fill it up

Ok, so it appears we’ve reached our nadir—you don’t have a trusty measuring tape (shame on you), you don’t own a Texas Instruments calculator (but how?), and that really is a copy of Treasure Islandin your glove box. The last option to determine your Crosstrek’s fuel tank capacity is to drive it to empty,or E on your dashboard. 
Be sure you’re close to a gas station when doing this. It would be very unfortunate if you ran out of gas in the middle of the Texas plains, surrounded by nothing but some shrubs, a few tumbleweeds, and an ominous, Western-style soundtrack that is definitely not playing in your head. 
Pull up to the gas pump (we’re assuming you made it out of the Texas Badlands alive—right?), and pump away. While the pump won’t give you an exact measure of your gas tank, it will provide a reasonably accurate approximation of your gas tank’s size.

How to save on fuel costs in a Subaru Crosstrek

The 2021 Subaru Crosstrek is a fuel efficiency champ, scoring 35 miles per gallon combined city/highway driving. But who wouldn’t want some tips to squeeze even more efficiency out of the Crosstrek than you ever thought possible?
Here are a few tips to wow even your fellow Subaru owners by maximizing your Crosstrek’s fuel efficiency and saving money:
  • Stay on top of maintenance: Letting wear and tear eat away at your Crosstrek will eat away at its fuel efficiency as well.
  • Drive carefully: If you can, avoid aggressive acceleration and/or sudden braking, which can both sap your Crosstrek’s fuel efficiency.
  • Don’t idle—even in the cold: Not only does idling hurt the environment (and as a Subaru driver, we assume you care?), but it's a waste of fuel! And so you know, the best way to warm up your car on a cold winter’s day is not to idle it—just get in and drive, and it will warm up quickly.
