quote: Corrosion: because the alcohol in ethanol corrodes aluminum, FFV components are made of stainless steel and E85 pumps must be modified or manufactured with stainless steel to prevent corrosion. Repeated exposure to E85 also corrodes the metal and rubber parts in older engines (pre-1988) designed primarily for gasoline.
