The government is trying to get rid of Methyl Tertiary Butylt Ether (MTBE) because of its harmful effects on the water systems in the USA, but the oxygenated gas will still be around...probably in the form of methanol or some other "gasohol" type additive during the winter months. Personally, I hate the oxy-gas. I hate the loss of power, the loss of mileage and the increased cost.
