I know a thread about this was already started quite a while ago, but couldn't find it. I noticed a while ago that gas at caseys is all 87 octane, including the ethanol blend, that used to be 89. I also noticed that the difference in price between regular unleaded and ethanol blended gas is bigger. Today the price of ethanol blend was $3.14 ad the regular was $3.47. Can someone explain what is going on with this?
Thanks
