There's no free lunch. Need to burn more ethanol for the same performance as gasoline.

My old turd is a Flex Fuel Engine.. I can run E85. While it is cheaper per gallon, you use a lot more for proper Stoichiometric Ratio. You can run more Timing with it. The Engine is a bit more snappy, but it goes fast.
