Not really, if you run out of Ethanol, the engine will run fine, but with reduced performance due to the increased knock, or more accurately due to the retardation of the timing/change of the mixture to avoid the possibility of increased knock.

Not changing your oil at the manufacturers recommended interval is foolish and stupid, and imho you deserve engine trouble if you dont! An ethanol topup is the least of your worries if you don't follow the cars basic maintenance requirements.
