But the harmless regulations should stay put, right?
Ethanol emerged as the oxygenating alternative to Methyl tertiary-butyl ether (MTBE), a petrochemical industry favorite that was showing up everywhere in ground water. Oxygenating agents in gasoline help gasoline combustion and contribute a bit to fuel economy, and help us not breathe unburned gasoline.
And it adds to smog, increases food costs and distorts markets. And the ethanol can damage your engine.
Other than that, I'm sure it's great. So great it should be optional.
