As of recently I found out there are a couple ethanol free gas stations around my area. Unfortunately none with 93 octane.
So my question is which is better 91 octane w/o ethanol or 93 octane w/ ethanol.
Hows the performance? Fuel economy? Etc? I know ethanol is corrosive and I was wondering if it would be a problem, mostly because I have a GM Stage 2 kit and it says it requires Premium fuel.
Any help is appreciated! Thanks!

Also I'm aware there is a thread exactly like this. I didn't want to resurrect it only because I wanted to get answers and it didn't really answer all my questions.

The E10 blend is fine. The SS/SC can handle full E85 blend with no issues as long as you get 80# injectors and a tune for E85 (It won't work on the Stage 2 tune or 42# injectors. Plus you have to have E85 stations in the area since using 93 after the E85 conversion isn't optimal).

You'll be fine, up here in Canada most of our fuel has ethanol in it (E10)...
