I have noticed that most posters here refer to 92 and 91 octane gasoline as the normal range. In Boston, 93 seems to be the standard high octane gas, with 87 being the standard low octane and 89 being the standard "plus" grade. It may be that certain stations sell 92, but I'm not sure I've seen any.
Sunoco sells an Ultra Premium 94 octane (I tried it once -- in the CAR that is -- and didn't notice any increase in performance or mileage over the 93).
What gives?
