    Abstract: Mineral lubricating oil compositions containing oil-soluble overbased alkaline earth metal hydrocarbon sulfonates, employed in internal combustion engines, are improved as to their antirust, sludge inhibiting and/or antiwear properties by incorporating into such compositions, in colloidal form, small amounts, for example 0.01 to 10.0 wt. percent, of the total oil composition, of in situ formed oil-insoluble inorganic alkaline earth metal phosphorus salts derived from the lower oxy or thio acids of phosphorus or from the corresponding oxides or sulfides of phosphorus which, upon hydrolysis, yield the lower oxy or thio acids of phosphorus. The preferred process of preparing such compositions involves the treatment of the neutral or overbased alkaline earth metal sulfonates, either of petroleum origin or of synthetic long chain alkaryl origin, or mineral oil concentrates thereof, and which have been in the past, conventionally employed as oil additives, with up to the stoichiometric amount of the phosphorus acid, thio acid, oxide or sulfide required to at least partially neutralize the free alkalinity of the overbased sulfonate, filtering therefrom any precipitate formed as a result of such treatment of the sulfonate or oil concentrate thereof, and recovering an oil-soluble alkaline earth metal sulfonate product, or oil concentrate thereof, containing colloidal oilinsoluble alkaline earth metal phosphorus compounds of reducing nature formed in situ.

    Abstract: A lubricating oil treatment system for internal combustion engines involves the circulation of such oil from an engine through an oil filter and returning the filtered oil to the engine. In this system, the oil filter or another chamber located either before or after the oil filter and through which the oil is circulated contains a relatively oil-insoluble solid inorganic element or particulate mixtures of two or more of such element, having an atomic number between 13 and 83, inclusive, and selected from the group consisting of Groups IIIA, IVA, VA, IB, IIB, IIIB, IVB, VB, VIB VIIB and VIII of the Periodic Table. The elements selected are those which upon being oxidized under the conditions obtained from their 0 valence state to an initial cation valence state have an E* oxidation-reduction potential greater than -0.94 volts, if measured in acid solution and greater than 0 volts, if measured in alkaline solution, with regard to the standard hydrogen electrode. Inert filter elements may be employed within the oil filter in layer form interspersed with retained solid particles of the aforementioned elements or the elements may be interspersed within the porous filter elements such as porous paper, diatomaceous earth, kaolin, kieselguhr, cotton waste and linters, activated clay, charcoal or fuller''s earth. Optionally, separate chambers containing the solid element may be inserted in the oil circulation system either before or after the oil filter. The preferred reducing elements are present conveniently in particle sizes ranging between about -4 and about 150 mesh standard Tyler screen size.

    Abstract: LUBRICATING OIL USED IN INTERNAL COMBUSTION ENGINES INVOLVES THE CIRCULATION AND RECIRCULATION OF THE OIL FROM THE ENGINE THROUGH AN OIL FILTER AND THE RETURN OF THE FILTERED OIL TO THE ENGINE. THE NOVEL SYSTEM AND TREATMENT CONTAINS A FILTER CARTRIDGE WITHIN THE FILTER CHAMBER WHICH CARTRIDGE IS CHARGED WITH RETAINED DISCRETE PARTICLES OF AT LEAST ONE RELATIVELY OIL-INSOLUBLE SOLID INORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE IODIDES OF ALKALI METAL AND ALKALINE EARTH METALS, INCLUDING MAGNESIUM, WITH OR WITHOUT THEIR ADMIXTURE WITH TRANSITION METAL COMPOUNDS AND/OR INORGANIC COMPOUNDS CONTAINING REDUCING ANIONS SUCH AS THOSE CONTAINING SULFUR OR PHOSPHORUS THEREIN. THE PASSAGE OF THE CIRCULATING OIL IN THE SYSTEM MAY BE, OPTIONALLY, THROUGH A CHAMBER IN THE CIRCULATING OIL SYSTEM WHICH IS AHEAD OF OR AFTER THE OIL FILTER, WHICH CHAMBER RETAINS THE SOLID DISCRETE PARTICLES OF SUCH A COMPOUND OR MIXTURE OF COMPOUNDS AND IN PLACE OF OR IN ADDITION TO SUCH COMPOUNDS BEING PLACED WITHIN THE OIL FILTER.
