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.
holy fuck you’re right. I always knew that higher quality fuels reduced knocking, but I thought it was a side effect of the fuel being more pure or something. I haven’t really put any thought into this since I was a kid
