Explanation:
Detailed explanation-1: -Fuel Economy and Performance FFVs are optimized for gasoline. If they were optimized to run on higher ethanol blends, fuel economy would likely increase as a result of increased engine efficiency. Ethanol also has a higher octane number than gasoline, which provides increased power and performance.
Detailed explanation-2: -How does using ethanol-blended gasoline reduce exhaust emissions? Ethanol is one of the best tools we have to fight air pollution from vehicles. Ethanol contains 35% oxygen. Adding oxygen to fuel allows it to burn more completely, which reduces tailpipe emissions such as carbon monoxide (CO).
