Lowest grade octane was 85 (positive on that) but cannot remember off hand what the other 2 grades were (mid and super), so I did not edit those and left as they were. All 3 grades were "ethanol free" (untested).

Not sure if I got the octane ratings right. They have all three grades of gas with NO ETHANOL in any of them. Alpine Market on wisconsin and mikes conoco on 93 south also have high octane non ethanol gas. This is the only station I know of with all three grades of good gas!
