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.
