As I understand it, the alcohol is added locally. From what I have read on the auto forums, while it is supposed to be limited to 10% right now (soon to jump to 15%), the distributers have been known to screw up and add more.
Any time you buy auto fuel, you will want to test it. Contact the EAA, they have a
very cheap fuel tester.
