How big is the gas tank on a 2016 Hyundai Sonata?

No matter which trim level or engine configuration you pick, your 2016 Hyundai Sonata will come with an 18.5-gallon gas tank. 
The 2016 Sonata’s efficient
Eco
trim comes with a 178-horsepower, turbocharged 1.6-liter four-cylinder engine paired with a seven-speed dual-clutch automatic transmission. This setup lets the Sonata Eco get up to 32 mpg combined and 38 mpg on the highway!
The other trims don’t disappoint, either. The
SE
,
Sport
, and
Limited
trims come with the model’s standard 185-horsepower 2.4-liter four-cylinder engine, achieving a combined 30 mpg
If you want something a little more spirited and a lot less efficient, the 2.0T has a 245-horsepower turbocharged 2-liter four-cylinder. It only gets up to 32 mpg on the highway and a combined 26 mpg, which still isn’t bad.

How to check your 2016 Hyundai Sonata’s gas tank size

If you’re not convinced that we’ve got your gas tank size right, you can always check for yourself! Here are a few ways to figure out your car’s fuel tank capacity:

Measure the gas tank

Crawl under your car with a tape measure and a calculator. In inches, measure the gas tank’s width, length, and height. Multiply those figures together, divide the total by 231, and the result should be how many gallons your tank holds. 

Check your owner’s manual

Your specific model year and trim level fuel tank details should be listed in your car’s owner’s manual. However, if you’ve misplaced the manual, you can always download a digital copy from the
Hyundai owners’ resource site

Drive till empty, then fill it up

This is probably the easiest, yet riskiest, method to check your gas tank size. Drive until your fuel indicator is in E. Just don’t go too far on an empty tank or you’ll end up stranded! Then go to the gas station and fill your car up. That will give you a good idea of how many gallons your fuel tank takes.

How to save on fuel costs in a Hyundai Sonata

Although the Sonata is already fairly efficient, there are things you can do to keep it that way. Try these tips:
  • Get your regular services done. Sticking to your regular
    car maintenance schedule
    will keep your Sonata running longer and more efficiently!
  • Slow down. The faster you drive, the more fuel you use. Drive at or below the speed limit to stay safe and save on gas.
  • Don’t idle when you’re parked. If you’ve parked your car, shut the engine off. Leaving it running just wastes gas.
