There
You should look also at the gas mileage thread. If I were just trying to get good highway mileage I'd be shooting for a low ethanol content. All things being equal, you'll get better mileage from a higher gas content for part-throttle driving. Ethanol is a great fuel for racing, but if we're just talking about cruising, every 10% in ethanol is about 3.3% less mileage.
So a 30% mix is right around 10% loss in mileage. All calculations based on 114,000 btu per gallon of gas vs 76,100 btu per gallon of ethanol.

I run the ZFG E50 tune so I get about 12-13 mpg in town and perhaps 15 mpg on a longer highway run. At the same time my fuel mix (50% E85 and 50% 93 octane E30) costs approximately $2.50 to $2.75 per gallon. Before the ZFG tune it would have been 91 octane E10 (at about one dollar more per gallon in cost) and about 14-15 mpg in town.

The only advantage to living in Illinois is that Ethanol is everywhere and cheap. I'm now running an e30 tune from gearhead. I had an e50 tune from 5 Star. I only miss the e50 tune cause after blending I averaged 3.20 per gallon. I will say though the gearhead tune at e30 shifts better and feels faster, however the per gallon went up to around 3.75.
