[Class 91] Lubricating oils are in use maintained charged with oxidation-inhibitor only slightly soluble therein by circulating portions of the oil through a mass of such inhibitor and returning them to the main body of oil. Conveniently a filter packing is made of or is coated, impregnated, or otherwise charged with one or more inhibitors, and is combined with the oil-filter of the motor or other engine. Suitable filters are those described in Specification 412,767, and in U.S.A. Specifications 2,071,529 and 2,071,550, which are provided with removable impregnated or loaded cartridges or plugs of wool, asbestos, mineral or glass wool, cotton, or activated clay. Inhibits or specified are aromatic sulphur compounds such as diphenyl and diphenol sulphides, and disulphides, phenyl mercaptans, phenyl polysulphides, the corresponding naphthol. anthrol, and phenanthrol compounds, sulphurized wood creosote, sulphurized cresols, and thiophenyl-betanaphthylamine ; metalloorganic compounds used with motor fuels, as anti-detonants ; metallic soaps, e.g. lead oleate.
