How to check your 2022 Toyota Prius’ gas tank size

If you can’t determine your trim level or drivetrain type, you can check your 2022 Toyota Prius gas tank size for yourself. Follow one or more of these methods to get the information on your Toyota Prius fuel tank capacity:

Measure the gas tank

Grab a tape measure and a calculator, and get ready to do some math. First, you’ll need to measure the width, length, and height of the gas tank. Multiply these measurements together, then divide by 231—the number of cubic inches in a gallon—to get your gas tank’s volume in gallons. 

Check your owner’s manual

Whip out your owner’s manual and check your specific drivetrain or look for a keyphrase like “fuel tank capacity” to find the page with the information you need on your 2022 Toyota Prius gas tank size.

Drive till empty, then fill it up

You can also drive until your fuel gauge hits “E” and then fill up to get a rough estimate of your Toyota Prius fuel tank capacity. It might be a little risky, but if you’re looking for excitement there’s no better way. Your measurement won’t be very accurate, but it’ll be close enough to give you a general idea of your 2022 Toyota Prius’ gas tank size.

How to save on fuel costs in a Toyota Prius

Curious about the Toyota Prius's fuel economy? You’re not alone. Understanding your Toyota Prius fuel economy is key for cutting back on your gas bill, which might be pretty low already considering the Prius gets 56 mpg combined
Still, there’s always room for improvement when it comes to saving money. Try these tips to cut back on your gas bill:
  • Perform regular maintenance. Don’t neglect wear and tear for too long—it could start to negatively impact your mileage. 
  • Drive with caution. If you don’t accelerate quickly and follow the speed limit, you’ll see a boost in your fuel economy. 
  • Don’t let your engine idle, especially in cold weather. Engine idling is a real killer when it comes to mileage. Avoid stop-and-go traffic when you can, and don’t warm up your car on a cold day.
