1. An apparatus of discriminating reformulated fuel, the apparatus comprising:
a fuel sensing unit comprising first and second electrode plates which are spaced and face each other, and a measuring part connected to the first and second electrode plates;
a fuel control valve unit comprising a control valve part blocking a fuel passage and a second actuator driving the control valve part; and
a control unit connected to the measuring part and the second actuator, and operating the second actuator based on a capacitance measured from the measuring part,
wherein the fuel sensing unit further comprises a first actuator allowing the second electrode plate to move toward the first electrode plate to reduce a separation distance between the first electrode plate and the second electrode plate.
