It's one of those things that makes me wonder what other applications are getting messed up by the different properties of this fuel. I have heard particularly that older cars, classics, and such have some real issues with the ethanol content as well. I suppose it's just a pain of the game but what is really annoying is that you can't find a place to buy the pure stuff if you need to. At the very least inform the customers what they are buying so they can decide if they want to support it or not or even if they want to prevent some defect the ethanol is causing. I'm not going to get on a soap box and say to stop making it, I'm just saying make the information available so consumers can make a choice. I have been putting off replacing my tank because I'm certain it'll just happen again unless I pony up and find a metal gas tank.
