But sir you are incorrect. The new vehicles, my truck included, will run and perform on ethanol gas because it's designed for Flex-Fuel but the gas mileage is significantly down graded. As for the damage ethanol fuel causes it's because of the condensation ethanol fuel promotes more than the actual performance of the fuel burning (BTUs) itself, which does burn hotter than regular unleaded gasoline. Also if you have a vehicle a little older like my 2008 work car, the ethanol laced fuel makes my engine ping/knock horribly. I could delve into the chemistry because I did the research when I bougt my new boat / Merc 250 outboard. They recommend absolutely no more than 10% ethanol by volume and even with that they require a stabilizer.
