About This Quiz

Fuel is a huge expense for many Americans, with the average driver shelling out just under $2,000 a year on gas, according to the Bureau of Labor Statistics. People with long commutes or higher costs of living can spend much more.

Gas guzzling also has an impact on the environment, spewing pollutants into the air that affect air and water quality, which eventually harms not only people but also plants and wildlife.

The good news is that there are dozens of steps you can take to improve fuel economy, protect the planet and keep more cash in your wallet. The bad news? A surprising number of widely known fuel saving tips have no basis in fact. As cars and technology have changed over the decades, people have kept on believing the same old fuel economy myths, rather than switching to strategies that actually make a difference.

That means you could be sweating it out in a broiling car because you're convinced that using the AC or rolling down the windows will blow your gas budget. It might also mean you're missing out on easy opportunities to cut fuel costs, like maintaining the right tire pressure, in favor of things that actually have zero impact on gas mileage.

Think you have what it takes to separate fact from fiction? Take our fuel economy myths quiz to find out!
