Gas mileage of ethanol-added gasoline?

[N2RJ]

As for the carbon neutrality of corn ethanol, strictly speaking, yes it is.

However, this doesn't take into account diesel fuel used for mechanized agriculture or CO2 released to make nitrogen fertilizer.

Food crop corn likely needs less CO2 because it's planted in crop rotation, versus fuel corn which is grown year after year on the same land.

Also, ethanol needs to be produced at an ethanol plant which also requires energy to run. Some of them run on coal.

It still however results in a net greenhouse gas reduction, but I hate the idea of burning coal to produce ethanol and it is still a pretty shitty fuel for most gasoline engines.

Food for thought and fuel for the discussion. :)
