Ethanol Blend gas or gasohol

[Chris Sawatsky]

Is there any reason not to use ethanol blended gas?
The stations that sell it here sell 90 octane gasahol for the price of 87 octane gasoline

While ethanol has a generally higher octane rating than gasoline, it has a lower energy content than gasoline. This is why Indy Cars get such crappy fuel economy. You would probably have to run a richer mixture to still get the same power.
Ethanol tends to be popular in some urban areas because it effectivly makes engines run leaner, leading to lower hydrocarbon emissions.
