Default Enmark 91Superblu non-ethanol gasoline...who has tried it?

Has anyone tried this out?

I used to buy my gas at Enmark regularly because they offered a discount on 93 octane on Tuesdays. However, I have noticed that my STi started not liking Enmark fuel many years ago and stopped buying it.

Not sure what changed, but noticed that the engine had trouble starting anytime I bought Enmark gas and it would continue for weeks afterwards even several tanks later. I've confirmed this multiple times going months between fillups at an Enmark and each time the same result. It definitely wasn't a fluke or a tank of "bad gas".

I assumed that Enmark fuels simply had a higher ethanol content in them than the place I usually filled up at.

Now I'm curious about the 91 octane non-ethanol. Curious to know if it does the same thing. Anyone else tried it? I haven't even priced it out yet. They seem to be advertising it as a "premium" fuel and I'm guessing that's above and beyond their normal 93 octane fuel.
