quote:the alcohol in todays fuels will DISOLVE aluminum
E85 is most certainly an issue with aluminum. They do not play well together.
However, the currently more common 10% ethanol is not a high enough strength to cause problems. Commercial fuel delivery systems, with aluminum parts, are rated compatible with the 10% blends.
As I don't think any of us are converting our Panteras to E85 compatibility, I doubt an aluminum tank will be an issue for normal use. In fact some of the early cars came with an aluminum tank from the factory.
