Why is ethanol more corrosive than gasoline?

But Voelcker then takes a swipe at higher ethanol blends: Ethanol in its purer forms, specifically E85, is long accepted as more corrosive to rubber and other engine components than gasoline. read more

Consider that most corrosion mechanisms will convert a metal into a cation through oxidation, e.g., Fe(0) --> Fe(II) and then dissolve away the metal salt product of that reaction. read more

Ethanol in its purer forms, specifically E85, is long accepted as more corrosive to rubber and other engine components than gasoline. That’s why carmakers have to develop “Flex-Fuel” engines specifically designed to withstand the effects of fuel that contains a majority of ethanol. read more
