I would be less worried about 92 in a modern car and run it over the 93 for normal daily driver.

How about a twist on the OP question that I’m still undecided on here in south Texas. 93 with ethanol or 90 with 0 ethanol. We have a lot of QuickTrip stations popping up along with some Murphy’s with 87 -0%.

More specifically in my 87 Carrera and 2000 S2000, both cars are fun cars and don’t get driven but every couple of months. Shoot the S2000 went a whole year since it was last driven. Both cars get Stabil Marine fuel treatment but concerned with water buildup over time in the tanks. Concerned with lower octane in hot weather and driven hard when put to use.

So would you drop down to 90 octane with no ethanol for a non-daily driver old/modern car?
