A few years ago here E10 was 89 octane, E0 was 87 that was the base blend. The refiners switched the base fuel to 85 octane, E10 now is 87, E15 is 88. To get E0 - 87 they have to blend premium with the 85 making the price way higher than E10. Like you said they were giving away octane.

I've read articles on raising the minimum octane in the US to make it easier for car manufactures to meet future FE goals.
