How big is the gas tank on a 2012 Hyundai Sonata?

The Hyundai Sonata’s gas tank size is the same across the board for the 2012 model. Each trim has an 18.5-gallon gas tank.

The 2012 Sonata did have a couple of options for engine configurations, though. This included a 200-horsepower, 2.4-liter four-cylinder, and a 274-horsepower, 2-liter turbocharged four-cylinder. The more powerful engine is only slightly less efficient than the base engine, earning just 26 mpg combined.

How to check your 2012 Hyundai Sonata’s gas tank size

If you’re skeptical about our accuracy, you can check for yourself in one of a few ways. Keep reading to see how!

Measure the gas tank

If you don’t mind taking a hands-on approach, get a measuring tape and calculator, and crawl under your car’s gas tank. Measure the tank’s width, length, and height in inches. Multiply those three figures together and divide the total by 231, which is the number of cubic inches per gallon. The result should tell you how many gallons your gas tank holds.

Check your owner’s manual

You can also check your car’s owner’s manual for the gas tank size. If you’ve misplaced the original manual, you can download a PDF version from the

Drive till empty, then fill it up

If you’re confident in your fuel gauge, you can try driving until the fuel indicator is on E, and then fill up. The number of gallons you have to buy should tell you how many gallons your tank can hold.
