I usually just go for high-volume stations that are affordable.
Been running mostly Costco 92 (They do so much volume that they refill their tanks twice a day), have had 0 issues and my FI tuner was able to get a few more degrees of timing than normal.
If you experience any performance issues, knocking, or unsmooth idle, especially NA, then there's a pretty major problem with the fuel you're getting.
