Enhancing Hypermiling Techniques
One way the new gasoline fuel reduces pollution is by adding oxygen molecules, which causes more complete combustion and reduces poisonous carbon monoxide. Oxygen is added to the fuel by blending it with alcohol - either petroleum-based methanol or corn-based ethanol. Hence, enhancing hypermiling terms and techniques. Reformulated fuel is required in nine metropolitan areas that persistently violate standards for ground-level ozone, or smog: Baltimore, Chicago, Hartford, Houston, Los Angeles, Milwaukee, New York, Philadelphia, and San Diego. Dozens of other areas that exceed ozone standards also joined the program, including the entire states of New Jersey and Delaware. Thirty-three of 67 Pennsylvania counties also will require the new fuel.
