Thank you for taking action on this important issue.

Ethanol contains 33 percent less energy per gallon than gasoline, and vehicles fueled with ethanol cover fewer miles per gallon than those running on conventional gasoline. The higher the ethanol blend, the lower the fuel economy, meaning consumers must fill up at the pump more frequently.

Beyond the damage to your wallet, ethanol can also damage vehicles and affect performance—corroding metals, causing rubber to swell and causing engines to break down more quickly. Some ethanol blends should not be used on certain engines and motors at all. EPA’s E15 waiver covers only 2001 and newer motor vehicles. E15 is not appropriate for heavy-duty vehicles or vehicles built before 2000, nor is it fit for boats and small motors, including those in lawnmowers and chainsaws.

This means you visit the gas station more frequently, paying more each time you fill-up, and you could be on the hook for costly engine repair bills.
