The oxegenate as I understand it (i never got better than C's in organic chem, so don't take this as if I was a fuel chemist) adds oxegen to the fuel to promote more complete combustion. This makes the fuel allready have some "air" in it, so you gotta dump more gas in to deal with the airflow you motor can inhale. So you gotta jet a wee bit richer because the changed stoichiometry of the fuel itself. Your motor will inhale a known CFM of air, you have to dispense enough fuel for this air. The oxygenated fuel allready has some air in it, so you gotta dump more fuel in to make up for that, since you are still inhaling the same CFM of air to begin with. Methyl-tertiary-butyl-ether is poisoning our water here in california, they keep finding it in wells and you can't get it out.
