In 2001 Utah County (where I reside)was using 10% ethanol mixed with gas and I put some in our 2 cycle weed eater and proceeded to weed eat and all of a sudden the engine started sputtering and coughing and before I could shut it off there was a huge pop and the engine stopped, took it to a repair shop and was told they were seeing a lot of this sort of thing, 2 cycles don't run to well on ethanol mixed gas,(blew the piston from it getting too hot). In 2004 Utah County applied for and was granted a waiver for NOT using ethanol mixture, I bet they got tired of all the complaints they were getting about it. So now there is no more ethanol in gas as of today (Too many people will complain about it if it's brought back)
