Ethanol blended fuels these days are not as bad as they once were due to the inhibitors they use. How ever when ethanol sits for a long period of time it becomes commingled with water and creates an environment for a type of bacteria to grow and creates an acid that will eat through most things. Many people will never experience this in their cars that are driven often due to the fact that the reaction won't have time to take place. In a nut shell it won't hurt 99% of everyone's vehicle. Also "pure" gasoline is very corrosive but also has additives and inhibitors blended in to cut down on the corrosion it could cause. But not all stations properly maintain their tanks and could lead to dilution of the gasoline and/or blended fuels and their additives. Just make sure to go to well kept stations with newer looking pumps and a general clean non-oldtimey appearance. And be sure to look for the states seal on the pumps or gas station window to show the pumps and the station it's self is annually inspected and certified.
