I always try to buy pure gas and not ethenol based fuels based on the fact that pure gasoline has higher btu energy compared to ethenol fuels. I have tracked it for the last year and I always get at least 15% better mileage when I use pure gas compared to ethenol. You can go the the website pure-gas.org for a list of gas stations that sell pure gas. It is listed by state and is easy to find a station. For my full size pickup it is equivelent to getting 40 free miles on every tank.
