In fact, with gas that doesn't contain ethanol, any condensation that develops does not mix with the gas but goes immediately to the bottom of the tank and starts working on it. Gas floats on water.
With E10, the condensation mixes with the ethanol and stays in suspension...to a point. When the ethanol becomes saturated with water, the water will ultimately precipitate out. Up until that point, you will not notice the water that is mixed with the E10. You will immediately notice any water mixed with the non E10 fuel since it will be at the bottom of the tank and will be the first liquid that goes to the carb.
