Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Going to road America for PCA driver's ed event, and I just realized that all the gas stations near the racetrack only have 91 octane is premium. Does anybody know of any nearby options with 93 octane?

All the towns very nearby sell 93. The town of Plymouth also has 93. The track also sells no ethanol no lead 98 IiRC. Have fun! The Chicago Region PCA puts on one hell of an event.
You can run into town at your lunch break for fuel. If you can only find 91 keep some room in your tank and top up with high octane at the track. As you know, your car will be just fine with 91 too.
There is a citco in town with 91 no ethanol added. Leaded 110 octane on other side of building, I have no cats so I topped it off with a few gallons.
I went to the neighboring town of Plymouth and there is only 91 octane. I Googled and it looks like there might be some 93 octane in Sheboygan
My rebuilt engine has slightly higher compression.
It's going to be very hot this weekend,
yes the knock sensor will step in if needed, but the engine has to knock for the sensor to send info to ecu to dial back ignition timing.
I may be over thinking this, but I think I am increasing my margin of safety. I under stand that if an engine us designed for 93 octane , 110 won't do anything, but the problem is there is only 91 available. I think a couple of gallons of 110 bring me close to 93, a fuel which should not detonate under any condition per this engine design

i know many states where the only gas one can buy is 91 octane and they drive and race with it fine. Youre not doing any harm so peace of mind doesnt hurt. the knock sensor is listening for even small amounts of knock and retards the timing way before damaging knocking is occurring. Porsche built this circuit well. Im not saying its impossible to damage the motor with 91 octane on raceday, but ive not seen a thread on it since ive been here. hopefully one of the more experienced race motor types can chime in and lend some more real world knowledge.
