How big is the gas tank on a 2019 Subaru Outback?

The 2019 Subaru Outback debuted with six trims: the 2.5i base,
2.5i Premium
2.5i Limited
, 3.6R Limited, 2.5i Touring, and 3.6R Touring. You can tell exactly what's under the hood of each of these models by checking out the number at the beginning of the trim's name. The 2.5i models run on a 2.5-liter four-cylinder engine, while the 3.6R models are powered by a 3.6-liter V6
No matter which trim you drive, you’ll find the same gas tank in each. Every 2019 Outback, from the base model to the Touring, has a fuel tank that will hold 18.5 gallons of gas
That’s pretty high for SUVs, which usually have gas tanks that can hold between 13 and 16 gallons. That, along with the Outback’s 27 mpg fuel economy, means you can get pretty far on just one trip to the gas pump in the 2019 Outback. 

How to check your 2019 Subaru Outback gas tank size

To double-check that your 2019 Outback’s gas tank lives up to those numbers, you can always use one of the strategies below.

Measure the gas tank

For this one, you’ll need just a couple of things: a tape measure and a calculator (or just an impressive capacity for mental math). Measure the width, length, and height of the tank, and then multiply them. Once you have that number, convert the cubic inches to gallons by dividing by 231 to get the final result. 

Check your owner’s manual

The fastest way to verify your gas tank size is by looking it up in your owner’s manual. It will be listed under “fuel tank capacity” or similar terminology.

Drive till empty, then fill it up

A word of warning before you try this one: don’t stray too far from a gas station. If you can do it safely, drive until your fuel tank is mostly empty. Once your fuel gauge hits “E”, you’ll know it's time to head to the station. You can then get a good estimate of the total capacity of your fuel tank based on how many gallons will fit.

How to save on fuel costs in a 2019 Subaru Outback 

While the 2019 Subaru Outback comes with a set of impressive statistics for its class, including a fuel tank size and gas mileage higher than many competitors, it’s still an SUV with a reputation for gas guzzling
If you’re looking for ways to make the most out of one tank, try some of these tips:  
  • Keep up with maintenance. If you want your car and its gas mileage to perform their best, it's a good idea to keep up with regular maintenance on all parts of your car. 
  • Avoid harsh acceleration. While it’s tempting to put the pedal to the metal, especially on highways and interstates where the speed limits are higher, make sure not to accelerate too quickly, as that can eat up a lot of gas faster than you might think.  
  • Don’t leave the car running. It’s tempting to warm up the car on colder days or to cool it down in the middle of summer before getting in. Just make sure not to do it for too long, as idling guzzles gas even when you’re not going anywhere.
