I figured it was a marketing gimmick to get you to buy 88 and then they would finally raise the price, but it’s been years. are they adding extra ethanol or something?

    Octane is a measure of how prone to knocking the fuel is, not energy.

    Knocking is premature combustion, I.e. why lead used to be added.
