1. An oil management system to reduce and remove an amount of soot, rust or other contaminating particles in an oil used in an engine, the oil management system comprising: an oil filter assembly including a housing defining a chamber, the chamber retaining a filter element and an additive cartridge
1. An oil management system to reduce and remove an amount of soot, rust or other contaminating particles in an oil used in an engine, the oil management system comprising: an oil filter assembly including a housing defining a chamber, the chamber retaining a filter element and an additive cartridge, the additive cartridge including a cartridge housing defining an additive chamber in which an additive is retained, the cartridge housing providing a flow pathway into the additive chamber via an inlet opening formed in the cartridge housing and an flow pathway out of the additive chamber via an outlet opening formed in the cartridge housing in order to continuously disperse a small quantity of the additive into the oil;an oxidation prevention means to prevent or diminish oxidation of metal in the oil management system; andan oil condition monitoring sensor coupled to an oil collection sump of the engine and separate from the oil filter assembly, the oil condition monitoring sensor configured to measure at least one parameter selected from the group consisting of an amount of rust particles per unit of oil, an amount of nitrogen in the sump, and an amount of oxygen-scavenging material in the sump. 2. The oil management system of claim 1, wherein the filter element includes a mechanical filter member comprising a porous material in which a portion of the particles are filtered out of the oil. 3. The oil management system of claim 1, wherein the filter element includes a centrifuge member having an outer peripheral surface. 4. The oil management system of claim 3, wherein the centrifuge member creates a centrifugal force on the oil within the filter element to cause the particles in the oil to move to the outer periphery surface. 5. The oil management system of claim 4, wherein the outer peripheral surface is removable from the filter element. 6. The oil management system of claim 3, wherein the filter element includes a mechanical filter member. 7. The oil management system of claim 1, wherein the filter element includes a means for creating an electrical field inside the filter element that causes the particles to agglomerate together in the oil. 8. The oil management system of claim 7, wherein the means includes a positive electrode and a negative electrode and the agglomerated particles are attracted to the positive electrode. 9. The oil management system of claim 8, wherein the filter element also includes a centrifuge member. 10. The oil management system of claim 9, wherein an outer periphery of the centrifuge member is a positive electrode that forms a portion of the means for producing the electrical field. 11. The oil management system of claim 1, wherein the additive cartridge housing includes a shroud over the outlet opening that provides an iso-static pressure region adjacent the outlet opening. 12. The oil management system of claim 11, wherein the shroud includes one or more openings that reduce pressure imbalance between the additive chamber and an area outside of the additive cartridge. 13. The oil management system of claim 1, wherein the inlet opening is located below a top edge of the cartridge housing. 14. The oil management system of claim 1, wherein the inlet opening and outlet opening are formed as part of an integral one-piece structure. 15. The oil management system of claim 1, wherein the flow pathway into the additive chamber includes a discharge port between the inlet opening and the additive chamber, the discharge port located in an air pocket above the additive in the additive chamber. 16. An oil management system to reduce and remove an amount of soot, rust or other contaminating particles in an oil used in an engine, the oil management system comprising: an oil filter assembly including a housing defining a chamber, the chamber retaining a filter element and an additive cartridge, the additive cartridge including a cartridge housing defining an additive chamber in which an additive is retained, the cartridge housing providing a flow pathway into the additive chamber via an inlet opening formed in the cartridge housing and a flow pathway out of the additive chamber via an outlet opening formed in the cartridge housing in order to continuously disperse a small quantity of the additive into the oil;an oil collection sump, the oil collection sump configured to collected used oil from the engine, the oil collection sum including an oxidation prevention means to prevent or diminish oxidation of metal in the oil collection sump; andan oil condition monitoring sensor coupled to the oil collection sump and separate from the oil filter assembly, the oil condition monitoring sensor configured to measure at least one parameter selected from the group consisting of an amount of rust particles per unit of oil, an amount of nitrogen in the SUMP, and an amount of oxygen-scavenging material in the sump. 17. The oil management system of claim 16, wherein the oxidation prevention means includes a blanket of nitrogen above the oil in the oil collection sump. 18. The oil management system of claim 17, wherein the nitrogen is configured to be located in an air space above the oil in the oil collection sump. 19. The oil management system of claim 18, wherein the nitrogen is pumped into the oil collection sump through a tube connected to the oil collection sump. 20. The oil management system of claim 16, wherein the oxidation prevention means includes an oxygen-scavenging coating. 21. The oil management system of claim 20, wherein the oxygen-scavenging coating includes nitrogen. 22. The oil management system of claim 16, wherein the oxidation prevention means includes metal passivation. 23. The oil management system of claim 22, wherein the metal passivation includes an oxide film. 24. A method for removing soot, sludge, and other insoluble particles from oil circulating through an oil management system in a vehicle, the oil containing a fully or partially formed additive package, the method comprising: moving the oil through an oil filter assembly, the oil filter assembly including a filter element and an additive cartridge;exposing components of the oil management system to an oxidation prevention means to prevent or diminish oxidation of metal in the oil management system; andmonitoring the condition of the oil with a sensor coupled to the oil collection sump and separate from the oil filter assembly, to measure at least one parameter selected from the group consisting of an amount of rust particles per unit of oil, an amount of nitrogen in the SUMP, and an amount of oxygen-scavenging material in the sump. 25. The method of claim 24, wherein the filter element includes a mechanical filter member with porous material capturing a portion of the particles and a pair of electrodes generating an electrical field to cause a portion of the particles to agglomerate on the positive electrode. 26. The method of claim 25, wherein the method also includes applying a centrifugal to cause a portion of the particles to move toward the positive electrode. 27. The method of claim 24, wherein the method also includes continuously dispersing a small quantity of additive into the oil from the additive cartridge. 28. The method of claim 27, wherein the oil is configured to flow through the additive cartridge after it flows through the filter element in the filter assembly. 29. The method of claim 24, wherein the exposing and monitoring occur in the same component of the oil management system.
