Is ethanol compatible with the existing petroleum infrastructure?
Lower ethanol blends such as E10 are currently mixed with gasoline and transported, stored, and dispensed in existing infrastructure. Higher ethanol blends, such as E85, require separate infrastructure because E85 cannot be used in all vehicles and it can corrode some materials. The existing petroleum fuel infrastructure could be used to transport and store E85, as long as components were properly cleaned and the fuels were not mixed. Special E85-compatible pump dispensers are available, and can be incorporated into existing fueling stations.
