The Difference Between E-10 and E-15
Ethanol is referred to as grain alcohol or ethyl alcohol. It is used in alcoholic beverages, but is also used in gasoline as an oxygenate. Ethanol used in gasoline applications is denatured which means that it contains a bittering agent in it to prevent it from being consumed by humans. Ethanol is used in gasoline typically at 10 volume percent (E-10) but can be found at higher concentrations in flex fuel vehicles which contain 85 percent ethanol. More recently E-15 has been introduced which is 15 percent ethanol.
Ethanol is fermented from starches such as corn, wheat, grain sorghum, barley and potatoes and well as from sugar crops such as sugar cane and sweet sorghum. Ethanol as an alternative fuel source was originally designed to use renewable resources in order to minimize the United States reliance on foreign oil.
