Years ago the old two tank above ground mom and pop gas stations would sell "any grade for the same price" Remember those stations? Some were parked right next to a grainery. Usually had at least two grades but some had many right to e85 Standard 87 rug e0 89 e10 Flexfuel 90e15 91e20 93e30 Every grade was the same price or occasionally the flex fuel options cheaper. What happened to these stations? Now days e0 is more expensive, 89 costs a lot more regardless of ethanol and 90 octane super doesn't seem to exist in any ethanol concentration, like it was discontinued state wide. I used to see them all over until about 6 years ago, not sure what happened.
