A system for blending low and high octane gasoline includes independent flow paths for each fuel between a supply source and a composite blend manifold and nozzle assembly, with the rate of flow of fuel in each flow path being under individual closed loop control, under an algorithm for comparing the ratio of the actual accumulated volumes of the low octane to the high octane fuel, relative to a statistically determined ratio of the ideal volume of said low to high octane fuel for the total actual accumulated volume of the sum of the volumes of the fuels at a given time, for providing a perfect blend relative to a preselected blend ratio.
