权利要求: WHAT IS CLAIMED IS: 1. A method of preparing a lubricating oil additive composition comprising reacting A. a nitrogen-containing reactant derived from reacting a first reaction product with a triglyceride, wherein the first reaction product is derived by reacting an alkanolamine and a base, wherein the nitrogen-containing reactant comprises three equivalents of a nitrogen-containing compound and one equivalent of glycerol, and wherein the nitrogen-containing reactant contains less than 10 mass percent of glycerol alkyl ester; B. a source of boron; and C. glycerol. 2. A lubricating oil additive composition comprising the reaction product of an (a) a nitrogen-containing reactant derived from reacting a first reaction product with a triglyceride, wherein the first reaction product is derived by reacting an alkanolamine and a base, wherein the nitrogen-containing reactant comprises three equivalents of a nitrogen-containing compound and one equivalent of glycerol, and wherein the nitrogen-containing reactant contains less than 10 mass percent of glycerol alkyl ester; (b) a source of boron, and (c) glycerol. 3. The lubricating oil additive composition of Claim 2 wherein the nitrogen- containing reactant is an alkanolamide. 4. The lubricating oil additive composition of Claim 3 wherein the alkanolamide is diethanolamide. 5. The lubricating oil additive composition of Claim 2 wherein the source of boron is boric acid. 6. A lubricating oil composition comprising A. major amount of an oil of lubricating viscosity and B. a lubricating oil additive composition comprising the reaction product of (i) a nitrogen-containing reactant derived from reacting a first reaction product with a triglyceride, wherein the first reaction product is derived by reacting an alkanolamine and a base, wherein the nitrogen-containing reactant comprises three equivalents of a nitrogen-containing compound and one equivalent of glycerol, and wherein the nitrogen-containing reactant contains less than 10 mass percent of glycerol alkyl ester; (ii) a source of boron, and (iii) glycerol. 7. The lubricating oil additive composition of Claim 6 wherein the nitrogen- containing reactant is an alkanolamide. 8. The lubricating oil additive composition of Claim 8 wherein the alkanolamide is diethanolamide. 9. The lubricating oil composition of Claim 6 wherein the source of boron is boric acid. 10. A method for reducing friction in an internal combustion engine comprising lubricating said engine with a lubricating oil composition comprising the lubricating oil composition in Claim 6. 11. A lubricating oil additive concentrate comprising from about 90 wt. % to about 10 wt. % of an organic liquid diluent and from about 10 wt. % to about 90 wt. % of the lubricating oil additive composition of Claim 2.
