A hess gas station I was at a few years ago put regular in the middle instead of on the left. Started pumping before I noticed. Also, as I totally believe you about driving all over the country, you should know that octane levels vary a bit in places like Wyoming.
The majority of states sell 87, which is what the majority of vehicles call for. Some states still sell 85/86 but this isn’t going to be the case long term since there aren’t many carburetor (older cars before fuel injection) vehicles still on the road. 85-89 for regular passenger cars, 91 or higher for performance vehicles.
