20% ethanol has to close to the solubility of ethanol in gasoline. After that you'll have two layers of liquids.
I recall reading some numbers that indicated that the decrease in miles per gallon with the mixture is the same as the percentage of ethanol. So that you'll go as far on 10 gallons of 80/20 gas/ethanol as you will on 8 gallons of gasoline.
