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?

Knock resistance is related to octane and not ethanol content directly I thought
You are correct. Ethanol does have a higher octane rating though so a blend of gas and ethanol will have a higher octane rating and hence knock resistance.
