A NORMALLY LIQUID HYDROCARBON FUEL CONSISTING OF HYDROCARBONS IN THE GASOLINE BOILING RANGE COMPOSED PREPONDERANTLY OF ALIPHATIC HYDROCARBONS CONTAINING FROM ABOUT 0.001% TO ABOUT 1% BY WEIGHT OF AN ORGANIC COMPOUND CONTAINING THE DICYCLOPENTADIENYLIRON NUCLEUS WHICH IS SOLUBLE IN THE FUEL AND WHICH IS A MEMBER OF THE CLASS CONSISTING OF DICYCLOPENTADIENYLIRON AND SUBSTITUTED DICYCLOPENTADIENYLIRONS IN WHICH THE SUBSTITUENTS ARE ON THE CYCLOPENTADIENYL RINGS AND CONSIST OF 1 TO 4 MEMBERS OF THE CLASS CONSISTING OF MONOHALOGENATED HYDROCARBON RADICALS OF 1 TO 12 CARBON ATOMS IN WHICH THE HALOGEN ATOM HAS AN ATOMIC WEIGHT OF AT LEAST 35, OXYGEN-CONTAINING ORGANIC RADICALS CONSISTING OF 1 TO 12 CARBON ATOMS, 1 OXYGEN ATOM AND THE REST HYDROGEN ATOMS, AMINO GROUPS, MONOAMINOALKYL RADICALS OF 1 TO 12 CARBON ATOMS, AND A SECOND DICYCLOPENTADIENYLIRON NUCEUS JOINED TO THE FIRST MENTIONED DICYCLOPENTADIENYLIRON NUCLEUS BY TWO DIVALENT HYDROCARBON BRIDGING RADICALS EACH OF WHICH CONTAINS 1 TO 12 CARBON ATOMS, THERE BEING NO MORE THAN TWO OF SUCH SUBSTITUENTS ON ANY ONE CYCLOPENTADIENYL RING.
