How many gallons of gas does a Chevy Cavalier get?

The fuel economy of a Chevy Cavalier varies significantly depending on the model year, engine size, and transmission. There's no single answer to how many gallons it gets. Instead, it's measured in miles per gallon (mpg). You'd need to specify the year and model of the Cavalier to find its EPA estimated fuel economy. Then, you can look up the fuel tank capacity for that specific year to figure out the range.
