A system and method for dispensing a fuel derived from one or more fuels having different octane ratings respectively stored in a plurality of storage tanks. The fuels are passed from their respective tanks to a mixing zone for mixing to form a blended fuel. The blended fuel is passed from the mixing zone to a dispensing nozzle while the octane rating of the blended fuel is sensed. The flow of each fuel from its tanks to the mixing zone is controlled accordingly to establish and maintain a predetermined octane rating of the blended fuel.

[ What is claimed is:] [1.] A method for blending at least two fuels having different octane ratings into a blended fuel having a predetermined octane rating, the method comprising the steps of:providing a first storage tank containing a first fuel having a relative low octane rating;providing a second storage tank containing a second fuel having a relative high octane rating;providing first and second conduits respectively extending from the first and second storage tanks;providing a blending chamber connected to the first and second conduits;providing a third conduit extending from the blending chamber to an outlet;flowing the first fuel from the first storage tank, through the first conduit and into the blending chamber;flowing the second fuel from the second storage tank, through the second conduit and into the blending chamber for blending with the first fuel;flowing the blended fuel from the blending chamber to the third conduit for passage to the outlet,measuring the octane rating of the blended fuel during the last step of flowing; andresponding to the measured octane rating of the blended fuel being different from the predetermined octane rating and increasing or decreasing the octane rating of the blended fuel by changing the flow of either one of the fuels into the blending chamber accordingly until the measured octane rating of the blended fuel corresponds to the predetermined octane rating.
