Squee, that's kinda odd. I noticed an increase of ~2mpg and noticeably more power when I started using ethanol mix instead of regular gas. I even switched back for a time just to see if it was just perception. I just drive an '05 Mazda 3 (2.3L NA engine). Maybe the reduction in power and fuel eff only affects larger engines (although I can't imagine why).
