Abstract
A dispenser for delivering different grades of gasoline through a single nozzle at each fueling position, includes a pair of hoses connected to the nozzle, one of which hoses is used for selectively delivering high octane gasoline, and the other of which hoses is for selectively delivering either low octane or mid octane gasoline through the nozzle, whereby a control system is programmed for monitoring the dispensing of low octane gasoline relative to the dispensing of mid octane gasoline, for injecting a sufficient quantity of high octane gasoline through the nozzle at the initiator of a mid octane dispensing cycle for compensating for low octane fuel remaining in the other hose from an immediately prior low octane dispensing cycle relative to a mid octane dispensing cycle.
