FUEL ADDITIVES, ADDITIVE COMPOSITIONS AND METHODS OF EMPLOYING SAME TO PREVENT CORROSION OF METAL SURFACES IN CONTACT WITH HOT GASEOUS COMBUSTION PRODUCTS Abstract of the Disclosure A fuel additive composition useful for incorporation in or admixture with fuels, particularly fuels containing vanadium and/or sodium as a contaminant such that upon combustion of the fuels containing or in the presence of said additive composition metal surfaces in contact with the resulting hot gaseous fuel combustion products are subject to less corrosion, contains one or more compounds providing the elements or elemental components magnesium, silicon, chromium and chlorine, these elements Mg, Si plus Cr, Cl being present in the additive composition in the weight ratio 1/>0.5/>1.0, respectively, the amount of Si to Cr being in the ratio 1:0.1-10. Additionally, the compound or compounds in said additive composition containing or providing the elemental components or elements silicon and magnesium preferably are capable of forming or provide the compounds SiO2 or MgO, respectively, in the hot gaseous fuel combustion products in a weight ratio greater than 1 part SiO2 to 1 part MgO. A fuel additive composition con- taining a solvent admixture made up of substantially equal parts by weight of a heavy aromatic petroleum naphtha fraction and a halo- genated hydrocarbon, such as the halogenated alkane 1,1,1-trichloro- ethane, the solvent admixture serving to dissolve and/or stably disperse a polysilicone, such as a polysilicone containing about 60% by weight SiO2, magnesium sulfonate and chromium naphthenate, the 1,1,1-trichloroethane, polysilicone, magnesium sulfonate and chromium naphthenate contributing the chlorine, silicon, magnesium and chromium components of the additive composition, has been found to be especially effective as a fuel additive composition.
