Wow I'm surprised there's 93 here! I've never been to Conoco... I might have to investigate.
I haven't been to or seen a station that DOESN'T have 93 octane in more years than I can remember. Though I actually do remember 30+ years ago when it wasn't common around my part of the east coast. (Pittsburgh to Washington, DC and into Northern VA).
On the other hand...I don't know where there is a single station that sells gas WITHOUT ethanol in it.
My cruze runs much better with fuel with ethanol in it, much less prone to engine knock. If you buy 87E10 and get phase separation(rare) you end up with something like 84 octane gas(no wonder this causes problems). 93E10 starts life as 91E0, so if phase separation does occur the lowest octane your car would see is 91E0(well and another layer of water/alcohol mix, but that would probably still be over 95 octane).
Nah, you need octane now cheapest way to get that is E85 and a tune to handle it. Nothing beats 96-105 octane for less than the cost of regular gas!!! Now with prices of regular gas so low the price difference is much smaller, Regular is averaging for $1.91 here, E85 is as low as $1.58Times have changed. It used to be we went looking for a place that sold aviation gas for our performance engines. Then there was the bottles of "104" to boost the pump stuff.
Thanks...but as jblackburn mentioned....I'm right smack in the middle of a large area with none around. Almost an hour drive in any direction to the first one. But that will be handy for plenty of others.Here is the best source I have found for non-ethanol gasoline.

Iowa produces ethanol. It's easier to find E85 here than 93
About 5 years ago I was in Iowa and couldn't figure out why the heck regular gas cost more than mid-grade!!! It wasn't until a few years later I found out Iowa law(at least at the time) required regular gas to be ethanol free. Same thing can be found here, 87E0 costs within 20 cents of 91E0, at that difference I have no idea why they even produce the lesser grade. With Iowa being the leader in E15/flex fuel stations, and being a large ethanol producer, I can't see why they would not have 93E10 for premium at more stations.87E0 and 91E10 are also the same price in Iowa. ($2.35/gal as of yesterday) The mid-grade is the cheapest because of the ethanol.
