Depending on the refinery, this increase in production cost varies from 5 to 15 cents per gallon. However, the price you will see at the pump cannot be accurately predicted. The price of cleaner-burning gasoline is subject to and will be determined by competitive forces in the marketplace. Many factors including production costs, weather, crude oil prices, taxes and supply and demand affect gasoline prices. It is expected that at least some of the increased cost to make cleaner-burning gasoline will be reflected in prices at the pump.
All gasoline is made from a recipe of basic ingredients.
Oxygenates have been added to gasoline since the mid-1970s to enhance octane. It is equivalent to leaving your car at home one day a week. Cleaner-burning gasoline reduces emissions and exposure to toxic substances, which result from the evaporation and combustion of gasoline. You should continue to take precautions to avoid exposure to gasoline vapors when pumping and handling any gasoline. You should never swallow or siphon any gasoline.
