I understand that most 'oxygenated' fuel contains ethanol as the
agent at around 10% by volume (YMMV). As ethanol has less
'energy content' than regular gasoline, mileage will be lower.
However, if it IS only 10% ethanol, mileage could (should) not be
10% lower (ethanol DOES burn after all) so 2-4% would sound
right. However, there may be more complex things at play here
with the knock & O2 feedback loops in modern computer-
controlled fuel inj systems, etc.
I can't see that there would be anything special about the refining
process for good ol' alcohol. However, I've always been one for
a good conspiracy theory, so I'll pass it on!
