Abstract:
1. A method comprising: measuring, via an octane analyzer that is integrated into a fuel pump, an octane measurement of a fuel sample while a stream of fuel is being dispensed from the fuel pump into a vehicle, rounding, via the octane analyzer, the octane measurement to a nearest recognized octane rating; comparing, via the octane analyzer, the rounded octane measurement with a listed octane rating for the fuel sample; and determining, via the octane analyzer, that the rounded octane measurement fails to match the listed octane rating for the fuel sample; communicating, via the octane analyzer to a user, an indication of an error in the listed octane rating for the fuel sample; computing, via the octane analyzer, a compensation for the user, based in part on the error; and reducing a price of fuel with the compensation.
