Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lubricant-additive composition containing a straight-chain monoalkyl (alkenyl) glycerin ester with good solubility in base oil and good shelf stability, and to provide a lubricant composition containing the same. SOLUTION: The lubricant-additive composition contains (A) a straight-chain monoalkyl (alkenyl) glycerin ester and (B) a compound having a melting point of 25°C or below and represented by the general formula (2) at a ratio (mass ratio) of the component (A)/the component (B) =1/9-9/1. In the general formula (2), R2represents an 8-24C aliphatic hydrocarbon group, m represents the number of 0 or 1, n represents the number of 1 or 2, Y represents any group selected from a hydrogen atom, a 1-3C alkyl group, and the general formula (3) wherein p represents the number of 1 or 2.
