if you bother to read the actual report, engine valves on cars not designed for E15 are getting pitted with ethanol

no wonder the idea of pushing ethanol content higher than 10% is floating around: it makes your car to die… slower than on the spot, but surely well before it should, effectively pushing you to buy a new car
