Oops
in some places in the US, 91 is the premium gas' octane.
Around here (and in North Dakota) ethanol is used to up the octane of premium gas. So the octane rating is higher, but gas mileage suffers. Ethanol sucks as a petrol alternative.

Yeah I don't think I would sweat it. If you think about it, the loaner cars at my Infiniti dealer are 07+ G35's and I can guarantee you not many people are putting 91 in them, when they return them.
