That's what happens when Gasoline is left exposed to the atmosphere. You didn't know that?
The fuel systems on new cars are sealed (with a vent for pressure buildup) to prevent the fuel being contaminated. Even Gasoline cans are sealed now.
Now if enough water gets into the fuel the Ethanol will separate. This is more of a problem for lower blends though.

Back on topic now.
Gonna make sure I stay informed if E15 becomes avaialble, to steer people clear of it unless their car manufacturer says it is OK for their year & model.

There is a lot to cover. Best way to learn IMHO is to keep up on the scientific news, DOE, and even USDA reports. Even just looking at the
GREET model helps. Notice there is a huge energy cost for Corn Ethanol but it takes far less Fossil fuels per mile and even less petroleum than straight Gasoline.
Due to Corn prices in the past E85 used to be attractive when there was excess supply but due to the demand for Ethanol for E10, E85 is now less than 1/10th the demand for Ethanol for E10. And they want to push for E15?
It is about the money.
