i've been riding along time and for some reason i havent heard how bad ethenol is. it is acid base and tears up gaskets, can go bad in two weeks leaving a form of algie in your system and little mico organisms eat the algie and poop out more acid. even with stabalizer fuel will go bad in 30 days. my daughters sled siezed up this weekend with 600 miles on it and know her season is over just cause i saved a few pennies for cheap gas. here is a site for ethenol free stations
