An interesting note around here (northeastern South Dakota). We are lucky to have the option of buying various ethanol blends at a lot of stations in the area. 10%, 30%, 85% ethanol blends are commonly available. Anyhow, during normal times, the greater the percentage of ethanol, the less expensive the gas is. Since crude oil is cheap and the ethanol industry is now hurting along with them, the difference in price is now gone. All the ethanol blends are now the same price or are much closer in price than they usually are.
