This is in part because cars running on gasoline with higher toluene levels or added alkylates get higher fuel economy than those running on gasoline with either MTBE or ethanol, Keller said. If California implemented this option, gasoline prices in the state would rise by a few cents to as much as 15 cents per gallon, depending on the length of time allowed to phase out MTBE and step up sales of nonoxygenated reformulated gasoline, he said. Retaining reformulated gasoline containing MTBE would be the most expensive option for California, in large part because of high costs of treating the water predicted to become polluted with the compound.
