The thing I'd be concerned about is that by the time they investigate the station and test the fuel, it's fine. Also, although I have a good handle on what's happening with the fuel, will I be believed?

I log my car all the time as it's tuned and v. sensitive to fuel quality. I've seen some pretty horrible knock-retarding/timing correction values during live data logging and it had to be issues like this at the station. I always have the best performance with Costco 93.
Go make 90 AKI/95 RON at a known good pump save some cash, they are designed to get all their performance out of regular european fuel and never recommend premium. Even much newer vehicles have marginal gains on 98/99 RON.
Exxon is exactly where I got a bad tank of gas. A station that had previously been fine. They recently switched pump styles to a single hose style. Before, they had 3 hoses, one for each grade.
Another poster provided the webpage of the agency responsible for compliance, which if you look at it has contact info towards the end of the page.
Another tact would be to contact ExxonMobil Directly - use this site: https://www.exxon.com/en/contact-us It includes a section for "Station Experience", and one of the items to comment on is fuel quality.
Or contact the fuel station directly...
The only way to hold them accountable is to report the issue to the appropriate places, and turn the heat up on them if they have in fact done something... If you just avoid them and never say anything to the agencies and powers that be that something seems amiss, should you ever expect a change?
