How big is the gas tank on a 2022 Toyota Avalon?

The 2022 Toyota Avalon has a gas tank ranging from 13.2 to 15.8 gallons across trim levels and more efficient powertrains. Let’s take a look:
  • Hybrid
    Limited: 13.2 gal
  • Hybrid XLE: 13.2 gal
  • Hybrid XSE Nightshade: 13.2 gal
  • XLE
    : 14.5 gal
  • Limited: 15.8 gal
  • Touring: 15.8 gal
As you can see, the hybrid powertrain option requires a slightly smaller gas tank. However, the efficiency of Avalon Hybrids allows them to outrun the conventional gasoline models significantly. Let’s put a microscope on it:
  • 2022 Toyota Avalon Hybrids: 43 combined mpg x 13.2 gal = 568 miles
  • 2022 Toyota Avalon (XLE): 25 combined mpg x 14.5 gal = 363 miles
  • 2022 Toyota Avalon (Limited & Touring): 25 combined mpg x 15.8 gal = 395 miles
And believe it or not, the 2022 Toyota Avalon Hybrid XLE model is only about $1,000 more than the standard XLE model. So it seems like a heck of a deal for almost 200 more miles per fill-up!

How to check your 2022 Toyota Avalon’s gas tank size

The nameplate on the back of your 2022 Toyota Avalon should tell you everything you need to know about its gas tank size, but you can also run some tests yourself. Here are some ways to manually check the gas tank size.

Measure the gas tank

First, grab your trusty tape measure. Then, locate your gas tank on the underside of your Avalon. Finally, to get the correct capacity, just multiply the tank's width, length, and height and divide the result by 231 (that’s the number of cubic inches in a gallon). 
And BAM! Your calculator should reveal the size of your gas tank.

Check your owner’s manual

This may be obvious, but your owner’s manual has the answer for any question you can imagine—including gas tank size. So brush the dust off, open it up, and locate “technical specifications” or “fuel tank capacity” within the table of contents to get to the correct page.

Drive till empty, then fill it up

Got an appetite for risk? You can always run your gas tank dry before filling up again. It’s worth mentioning that if you don’t literally roll into the gas station, the measurement may not be 100% accurate—but it will be pretty close!

How to save on fuel costs in a Toyota Avalon

As mentioned earlier, opting for a hybrid model is the number one way to save money on fuel costs. But regardless of which Toyota Avalon variant is parked in your garage, there are some additional strategies you can implement to manage costs at the pump:
  • Keep up with maintenance. Want your Avalon to achieve its full potential? Avoiding unnecessary wear and tear can help maximize fuel efficiency.
  • Drive carefully. Being too aggressive on the gas pedal can drastically decrease fuel efficiency.
  • Avoid idling, especially in cold weather. Simply put, every minute your car is idling is wasting fuel. Instead, it’s better to gently drive around to warm up your engine.
