The invention claimed is: 1. A lubricating oil additive comprising at least one lubricating oil additive selected from the group consisting of (1) to (5) below: (1) a lubricating oil additive obtained by dissolving Component (A) in Component (B) comprising an amine-based antioxidant; (2) a lubricat
The invention claimed is: 1. A lubricating oil additive comprising at least one lubricating oil additive selected from the group consisting of (1) to (5) below: (1) a lubricating oil additive obtained by dissolving Component (A) in Component (B) comprising an amine-based antioxidant; (2) a lubricating oil additive obtained by reacting Component (A) with Component (B) comprising a succinimide and/or derivative thereof; (3) a lubricating oil additive obtained by reacting Component (A) with Component (B) comprising an aliphatic amine having 8 to 30 carbon atoms; (4) a lubricating oil additive obtained by reacting Component (A) with Component (B) comprising a mixture of an amine-based antioxidant and a succinimide and/or derivative thereof; and (5) a lubricating oil additive obtained by reacting Component (A) with Component (B) comprising a mixture of an amine-based antioxidant and an aliphatic amine; wherein Component (A) comprises at least one compound selected from the group consisting of zinc salts of phosphorus compounds represented by formulas (2): wherein X4, X5, X6, and X 7 are each oxygen and R14, R15, and R16 are each independently hydrogen or a hydrocarbon group having 1 to 30 carbon atoms provided that at least one of them is hydrogen. 2. The lubricating oil additive according to claim 1, wherein the succinimide and/or derivative thereof is a compound having a base number of 5 mgKOH/g or more determined by a hydrochloric acid method. 3. The lubricating oil additive according to claim 1, wherein the derivative of the succinimide is a boron compound derivative of the succinimide. 4. The lubricating oil additive according to claim 1, wherein the aliphatic amine is a tertiary amine. 5. A lubricating oil additive comprising the lubricating oil additive as defined in claim 1 and at least one selected from the group consisting of lubricating base oils, anti-oxidants, ashless dispersants, metallic detergents, friction modifiers, anti-wear agents, corrosion inhibitors, rust inhibitors, demulsifiers, metal passivators, anti-foaming agents, dyes, and viscosity index improvers. 6. A lubricating oil composition comprising a lubricating base oil and the lubricating oil additive as defined in claim 1. 7. A process for producing a lubricating oil additive comprising at least one process selected from the group consisting of processes (1) to (5) below: (1) dissolving Component (A) in Component (B) comprising an amine-based antioxidant; (2) reacting Component (A) with Component (B) comprising a succinimide and/or derivative thereof; (3) reacting component (A) with Component (B) comprising an aliphatic amine; (4) reacting Component (A) with Component (B) comprising a mixture of an amine-based antioxidant and a succinimide and/or derivative thereof; and (5) reacting Component (A) with Component (B) comprising a mixture of an amine-based antioxidant and an aliphatic amine having 8 to 30 carbon atoms; wherein Component (A) comprises at least one compound selected from the group consisting of zinc salts of phosphorus compounds represented by formula (2): wherein X4, X5, X6, and X 7 are each oxygen and R14, R15, and R16 are each independently hydrogen or a hydrocarbon group having 1 to 30 carbon atoms provided that at least one of them is hydrogen. 8. A process for producing a lubricating oil composition comprising blending a lubricating base oil with the lubricating additive as defined in claim 1. 9. The process for producing a lubricating oil comprising according to claim 7, wherein a temperature at which compound (A) is dissolved in and reacted with component (B) is in a range of 30 to 90° C. 10. The lubricating oil additive according to claim 1, wherein the additive comprises at least one additive selected from the group consisting of (2) to (5). 11. The process for producing a lubricating oil additive according to claim 7, wherein the process comprises at least one process selected from (2) to (5). 12. The process for producing a lubricating oil additive according to claim 7, wherein a reaction ratio of Component (A) to the aliphatic amine or the succinimide and/or derivative thereof is 1 part by mass: 0.1 to 30 parts by mass. 13. The lubricating oil additive according to claim 1, wherein the aliphatic amine in additive (3) has 12 to 30 carbon atoms. 14. The process for producing a lubricating oil additive according to claim 7, wherein the aliphatic amine in process (3) has 12 to 30 carbon atoms.
