1. A system comprising:
a premium octane pipe capable of flowing a premium octane neat gasoline and comprising a first valve capable of regulating flow through the premium octane pipe at a known rate;
a regular octane pipe capable of flowing a regular octane neat gasoline and comprising a a second valve capable of regulating flow of the regular octane gasoline through the regular octane pipe at a known rate;
a butane pipe capable of flowing butane and comprising a third valve capable of regulating flow through the butane pipe at a known rate;
a first analyzer cell connected to the premium octane pipe capable of continually obtaining a premium research octane number and a premium motor octane number;
a second analyzer cell connected to the regular octane pipe capable of continually obtaining a regular research octane number and a regular motor octane number; and
a receptacle downstream of the first analyzer cell and the second analyzer cell that is capable of receiving and blending the premium octane gasoline, the regular octane gasoline, and the butane to produce a finished gasoline,
wherein the first valve, the second valve, and the third valve are capable of regulating a blend ratio of the premium octane gasoline, the regular octane gasoline, and the butane in the blend based on the premium research octane number, the premium motor octane number, the regular research octane number and the regular motor octane number.
