Some info here:
E85 is an alcohol fuel mixture that typically contains a mixture of up to 85% denatured fuel ethanol and gasoline or other hydrocarbon (HC) by volume. On an undenatured basis, the ethanol component ranges from 70% to 83%. E85 as a fuel is widely used in Sweden and is becoming increasingly common in the United States, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production; however as yet, there are about 1500[1] filling stations selling E85 to the public in the US, and, until recently, only three in Canada.[2][3]. It is also available across most of the Maxol chain in Ireland.
