I think its been around since the 70s and the only thing changed
are the ratios of oxygents to fuel. This web page has some info:

Reading it I learn:
Oxygenated fuels have less fuel by volume so milage may drop 1-2MPG.
They have been used for a long time to increase octane ratings (phased
in as lead phased out).
Articles claim no performance changes but I expect that relies
on a sophisticated fuel injection system that can adjust the fuel
to maintain the correct fuel/air ratio. An engine with a carberetor
is going to run leaner (and hotter).
