Aluminum is highly susceptible to damage from exposure to ethanol (C2H6O).

Ethanol contains oxygen, which is happy to interact with any susceptible metals it comes in contact with, to form oxides. During the burning process, the ethanol molecule breaks down to CO2 (carbon dioxide) and H2O (water).


One example of a mistake: Lexus had to recall all the 2.5/3.5L V-6s to replace the fuel rails as they were originally made out of aluminum. They were replaced with stainless steel units.
