    Abstract: The present invention provides for the use of certain oil soluble iodides to enhance the oxidation resistance of lubricating oils and fuels, and for the novel formulated compositions containing these iodides. Oil soluble iodides such as C.sub.16 to C.sub.78 alkyl ammonium as well as oil solubilizable or dispersible iodides such as CoI.sub.2, CuI, KI and NaI in combination with a suitable dispersing agent may be used. Typically a minor amount of additive, from about 40 to about 1000 ppm is used. The additive is effective as an antioxidant in a variety of different types of base and formulated oils.

    Abstract: Heavy oils containing metalloporphyrins principally of nickel and vanadium are demetallized using an oxidizing agent such as aqueous hydrogen peroxide and catalytic amounts of phosphoric acid, preferably with tungstic acid in combination with a phase transfer agent. Up to 99% of the Ni and V are deposited in the aqueous phase and are removed from the oil. The homogenous, water soluble reactants and catalyst have the advantage of being separated more easily from the Ni and V dissolved in the aqueous phase than the same metals deposited on solid phase heterogeneous catalysts.
