How big is the gas tank on a 2022 Subaru Outback?

If you’re a Subaru fan, then chances are you’re quite familiar with the Outback, arguably their signature vehicle. It’s a fun, spunky little station wagon that has the power and “go anywhere” attitude of a rugged SUV.
The 2022 Outback, in particular, is offered with either a standard or turbocharged 2.4-liter four-cylinder engine but regardless of engine size, the total fuel capacity is the same—18.5 gallons.

How to check your 2022 Subaru Outback’s gas tank size

If you’re more hands-on and want to see for yourself, then don’t just take our word for it. Here are a few ways that you can determine your gas tank size.

Measure the gas tank

If you’re not averse to a little math, you can use a calculator and measuring tape to figure out your gas tank size. First, you need to multiply the length, width, and height of the tank. Next, take your result and divide it by 231, which is the number of cubic inches in a gallon.

Check your owner’s manual

This method is a bit more boring, but it gets results. You can always look in your owner’s manual to determine your Outback’s fuel capacity. Check the index for any relevant terms, like “fuel economy” or “gas tank.”

Drive till empty, then top it off

The last method is a bit riskier than the other two. You could drive around until the tank is almost bone dry, then fill it all the way back up. It won’t be the most precise measurement, but you’ll still get an approximate idea of your gas tank size as well as how far you can go on a single tank.

How to save on fuel costs for a 2022 Subaru Outback

At 29 combined mpg, the 2022 Outback’s fuel economy is pretty good, but what if it was better?
Have a gander at these tips for saving gas (and money) with your Outback:
  • Keep up with maintenance. Remember those tire rotations and oil changes! Performing regularly scheduled maintenance will keep your car in good shape and prevent the fuel economy from taking a downward turn. 
  • Drive carefully. Keep fuel costs low by maintaining steady pressure on the gas pedal. Avoiding hard braking and easing off the gas early when you’re approaching a stop sign can also go a long way in maximizing your fuel economy. 
  • Don’t let your car idle. Idling isn’t the only way to warm up your car in the winter! Instead, you can gently drive your car for a couple of minutes to warm up the engine and save gas. But you might need to wear an extra sweater!
