I myself am most interested in E10-E15 vs pure, but the high ethanol mixes are interesting as well.
My cobalt is an 010, the buick was a 98, the dodge is an 01. E10 VRS pure is going to be hard to get accurate data on since normally (at least here) only Premium 93 octane is ethanol free which makes it rather moot points.

Also around here a lot of the ethanol gas from 3rd parties is 89 octane (aka 87 gas mixed with ethanol) sadly most of the big boys are mixing 84 octane with ethanol to save money which I believe is why we are seeing an increase in crap MPGs from ethanol fuel.

Mixing the lowest possible grade gasoline with ethanol is a recipe for failure.

Heck, might as well mix half a tank of #1 bunker oil with ethanol, not much different.
