Re: ethanol blends
Vin, in some areas we do blend ethanol. "E85" fuel is 15% ethanol, 85% gas. But a 5% ethanol blend is far more common. The midwest states of the US are the most common areas to find ethanol fuel as those states have the farmers that push the product and also have the ethanol production capabilities. I believe Illinois is the leading state producing ethanol for fuel. Some say that it does harm engines, especially the blends that have a higher % of ethanol, as I understand it, ethanol acts as a cleaning agent and reduces lubricity properties (but I've actually never checked into that, it is just what I have been told), I presume they have to add a lubricating agent to the E85 blend.
Seems to me I read a study not to long ago that showed that it takes more energy to produce ethanol blend fuel than it contributes? Not sure if that was credible, I didn't check the source and don't recall if the author had an adjenda of his/her own.
