there has been "up to 10% ethanol" here in Washington for at least 10 years, I found a place that sells ethanol free gas, I have noticed no difference in the way it runs, so for the extra price and the inconvenience of having to go into the store twice, once to pay and once to get the change, as well as the inconvenience of actually getting to the place. I'll just stick with the 10% stuff. Mileage suffers a little bit. It is a little ridiculous that they do all this in the name of environmental protection or whatever excuse they are using. But I'm pretty sure I don't have the political horsepower to change any of it.
