Ethanol produces less heat energy per gallon than gasoline, so you should get more mpg without it. There's an interesting chart here
that says E10 has 96.7% of the energy of gasoline, and info here
where the govt admits that mpg suffers by up to 5%. Automakers say ethanol harms your engine
, and it causes problems
in the economy and the world food supply.
