Patent ID: 7967876

Claim:
A method of producing a fuel composition comprising: treating an alloy with an organic compound; solubilizing the treated alloy in a diluents; and combining the treated alloy with a motor gasoline fuel; wherein the alloy comprises the following generic formula (A a ) n (B b ) n (C c ) n (D d ) n ; wherein each capital letter is a metal except for boron, germanium, arsenic, antimony, tellurium, and polonium; wherein A is a combustion modifier selected from the group consisting of Mn, Fe, Co, Cu, Ca, Rh, Pd, Pt, Ru, Ir, Ag, Au, and Ce; B is a deposit modifier selected from the group consisting of Mg, Al, Si, Sc, Ti, Zn, Sr, Y, Zr, Mo, In, Sn, Ba, La, Hf, Ta, W, Re, Yb, Lu, Cu and Ce; C is a corrosion inhibitor selected from the group consisting of Mg, Ca, Sr, Ba, Mn, Cu, Zn, and Cr; and D is a combustion co-modifier/electrostatic precipitator enhancer selected from the group consisting of Li, Na, K, Rb, Cs, and Mn; wherein each subscript letter except n represents compositional stoichiometry; wherein n is greater than or equal to zero and the sum of the n's is greater than or equal to 2; and wherein the alloy of the fuel additive composition comprises at least two different metals; and with the proviso that if the metal is cerium, then its compositional stoichiometry is less than about 0.7.
