Another interesting question I keep thinking I need to find data to figure out. My dad keeps better track than I do, but we have both noticed that the fuel efficiency you get with the 10% ethanol gas is worse than the gas without ethanol. If the decrease in MPG is enough, it negates the purpose of the enthanol, so what’s the point?
The most straightforward way to decrease the amount of pollution going into the air is to drive less!!
