The disclosure is directed to a method of enhancing a fuel value for a used or waste lubricating oil, lubricating oils having improved combustion and emission characteristics, and a business method for distributing and using waste oils as components of primary combustion fuels. In one embodiment, there is provided a lubricating oil composition having improved combustion and emission properties when burned as a used lubricating oil composition. The lubricating oil composition includes a major amount of oil of lubricating viscosity and a minor combustion improving amount of a combustion improving additive.

What is claimed is: 1. A fuel composition comprising fuel and from about 5 weight percent up to about 95 weight percent of a lubricating oil composition having improved combustion and emission lowering properties when burned as a used lubricating oil composition in the fuel composition, the lubricating oil composition comprising an oil of lubricating viscosity and from about 0.1 to about 1000 ppm total metal from a combustion improving additive. 2. The fuel composition of claim 1, wherein the oil of lubricating viscosity comprises an oil selected from the group consisting of machine oils, gear oils, hydraulic oils, rolling mill oils, transmission oil, crankcase oils, and the like. 3. The fuel composition of claim 2, wherein the oil is contaminated with water. 4. The fuel composition of claim 2, wherein the oil of lubricating viscosity is contaminated with wear products from lubricated surfaces. 5. The fuel composition of claim 1, wherein the combustion improving additive comprises a component selected from the group consisting of lithium, sodium, potassium, calcium, strontium, barium, chromium, manganese, iron, copper, cobalt, ruthenium, rhodium, palladium, osmium, platinum, lanthanum, cerium, iridium, mixtures of two or more of the foregoing, and alloys of two or more of the foregoing. 6. The fuel composition of claim 1, wherein the combustion improving additive comprises a manganese tricarbonyl compound. 7. The fuel composition of claim 6, wherein the manganese tricarbonyl compound comprises a compound selected from the group consisting of cyclopentadienyl manganese tricarbonyl, methylcyclopentadienyl manganese tricarbonyl, dimethylcyclopentadienyl manganese tricarbonyl, trimethylcyclopentadienyl manganese tricarbonyl, tetramethylcyclopentadienyl manganese tricarbonyl, pentamethylcyclopentadienyl manganese tricarbonyl, ethylcyclopentadienyl manganese tricarbonyl, diethylcyclopentadienyl manganese tricarbonyl, propylcyclopentadienyl manganese tricarbonyl, isopropylcyclopentadienyl manganese tricarbonyl, tert-butylcyclopentadienyl manganese tricarbonyl, octylcyclopentadienyl manganese tricarbonyl, dodecylcyclopentadienyl manganese tricarbonyl, ethylmethylcyclopentadienyl manganese tricarbonyl, and indenyl manganese tricarbonyl. 8. The fuel composition of claim 7, wherein the manganese tricarbonyl compound comprises cyclopentadienyl manganese tricarbonyls which are liquid at room temperature selected from the group consisting of methylcyclopentadienylmanganesetricarbonyl, ethylcyclopentadienyl manganese tricarbonyl, mixtures of cyclopentadienyl manganese tricarbonyl and methylcyclopentadienyl manganese tricarbonyl, and mixtures of methylcyclopentadienyl manganese tricarbonyl and ethylcyclopentadienyl manganese tricarbonyl. 9. The fuel composition of claim 1, wherein the lubricating oil is contaminated with rolling mill oil. 10. The fuel composition of claim 1, wherein the lubricating oil has a vapor pressure of less than about 0.001 torr at 20° C. and less than about 1.0 torr at about 120° C. 11. The fuel composition of claim 1, comprising from about 50 weight percent up to about 95 weight percent of the lubricating oil composition, wherein the lubricating oil composition comprises from about 0.1 to about 100 ppm total metal from the combustion improving additive. 12. The fuel composition of claim 1, comprising from about 5 weight percent up to about 50 weight percent of the lubricating oil composition, wherein the lubricating oil composition comprises from about 100 to about 1000 ppm total metal from the combustion improving additive. 13. The fuel composition of claim 1, wherein the fuel composition contains from about 0.1 to about 100 ppm total metal from the combustion improving additive.
