1. A method for lubricating metal during working thereof which comprises applying to said metal a water-free composition comprising (A) a major amount of a lubricating oil; (B) a minor amount of a basic alkali metal salt of at least one sulfonic carboxylic and organic phosphoric acids and phenols or a borated complex of said basic alkali metal salt; and (C) a minor amount of at least one sulfurization product of an aliphatic, arylaliphatic or alicyclic olefinic hydrocarbon containing from about 3 to about 30 carbon atoms, said sulfurization product containing active sulfur. 2. A method according to claim 1 wherein component C is prepared by reacting at about 50°-300° C., under superstomspheric pressure, sulfur and hydrogen sulfide with at least one olefinic compound containing 3 to about 30 carbon atoms to form a sulfurized mixture, about 0.3-3.0 gram-atoms of sulfur and about 0.1-1.5 moles of hydrogen sulfide being used per mole of olefinic compound; and removing from said sulfurized mixture substantially all low boiling materials including unreacted olefin, mercaptan and monosulfide. 3. A method according to claim 2 wherein the olefinic compound is an olefinic hydrocarbon containing from 3 to about 20 carbon atoms. 4. A method according to claim 3 wherein the olefin is propene, isobutene or a dimer, trimer or tetramer thereof, or a mixture thereof. 5. A method according to claim 4 wherein the olefin is isobutene or diisobutene. 6. A method according to claim 1 wherein said composition additionally contains (D) at least one chlorinated wax. 7. A method according to claim 1 wherein said composition additionally contains (D) at least one chlorinated wax. 8. A method according to claim 5 wherein said composition additionally contains (D) at least one chlorinated wax. 9. A method according to claims 1, 2, 3, 4, 5, 6, 7 or 8, wherein component (B) is prepared by contacting, at a temperature between the solidification temperature of the reaction mixture and its decomposition temperature; (B-1) at least one acidic gaseous material selected from the group consisting of carbon dioxide, hydrogen sulfide and sulfur dioxide, with (B-2) a reaction mixture comprising (B-2-a) at least one oil-soluble sulfonic acid, or derivative thereof susceptible to overbasing; (B-2-b) at least one alkali metal selected from the group consisting of lithium, sodium and potassium, or a hydroxide, alkoxide, hydride or amide thereof; (B-2-c) at least one lower aliphatic alcohol; and (b-2-d) at least one oil-soluble carboxylic acid or functional derivative thereof. 10. A method according to claim 9 wherein reagent B-1 is carbon dioxide. 11. A method according to claim 10 wherein the ratios of equivalents of the components of reagent B-2 are: (B-2-b)/(B-2-a)--at least 4:1; (B-2-c)/(B-2-a)--between about 1:1 and about 80:1; (B-2-d)/(B-2-a)--between about 1:1 and about 1:20. 12. A method according to claim 11 wherein component (B-2-d) is at least one hydrocarbon-substituted succinic acid or functional derivative thereof and the reaction temperature is in the range of about 25°-200° C. 13. A method according to claim 12 wherein component (B-2-a) is an acid represented by one of the formulas R 1 (SO 3 H) or (R 2 )H x T(SO 3 H) y in which R 1 and R 2 are each independently an aliphatic radical free from acetylenic unsaturation and containiong up to 60 carbon atoms, T is an aromatic hydrocarbon nucleus, x is a number from 1 to 3, and r and y are numbers from 1 to 4. 14. A method according to claim 13 wherein component (b-2-a) is a alkylated benzenesulfonic acid. 15. A method according to claim 14 wherein component (B-2-b) is sodium or a sodium compound. 16. A method according to claim 15 wherein component (B-2-c) is at least one of methanol, ethanol, propanel, butanol and pentanol and component (B-2-d) is at least one of polybutenyl succinic acid and polybutenyl succinic anhydride wherein the polybutenyl group comprises principally isobutene units and has a number average molecular weight between about 700 and about 10,000. 17. A method according to claim 16 wherein component (B-2-c) is methanol.
