The Sunoco station has a separate pump nozzle for their "Ultra 93" so it IS available but for more money....

I asked the same question some years ago to the driver of a gas tanker dropping a load of gas at Murphy's Mobil (now Irving) at the corner of Moultonboro Neck Road.
He was dropping a load of 93 octane gas that came up from the Chelsea/Revere fuel terminal in MA. He said most fuel delivered to NH stations originate from the Portsmouth fuel terminal that carry only 91 octane for their premium.
Some gas stations in MA like Shell and Sunoco list 93 Octane for their premium. Many others show 91 octane.
Long gone are the days of 104+ for Sunoco 260. And yes, it made a difference for the 11 to 1 or higher compression fire breathers roaming the streets.
