Living in Minnesota, where E10 is mandatory, I find it interesting how the topic of E85 "flex fuel" engines are heavily advertised. Lots of E85 fuel stations up here. But, what is never mentioned is the drop of 21-24% in your fuel miliage when you use E85 due to loss of BTU's compared to E10 or pure 100% gasoline. Sure, less oil is purchased from OPEC, which is good; however the cost of E85 is within a couple pennies per gallon. But until the cost of E85 reflects the loss of energy, it's overpriced. Although it does save petroleum imports in a very minor way, it must be more heavily subsitized somehow. I know of nobody up here who uses it after trying a couple tankfuls, and watching how fast the fuel needle drops. Just a few thoughts I thought I'd pass on to those who think E85 is a wonderful alternative. Comments? Flames?
