An additive for lubricant or fuel, comprising at least one member selected from substituted hydroxy aromatic ester derivatives represented by general formulae (I) and (II), (wherein R¹ through R⁵ represent each an organic group having six or more carbon atoms; a, b, d, e, k and m represent each 1 to 3; c, f, g, i and j represent each 0 to 3; h represents 0 to 4, provided f+g=1 to 3 and h+i=1 to 6); a lubricant or fuel additive composition containing the same; and a lubricant or fuel composition containing the same. The additive is suitable as an ashless cleaning agent that is excellent in high-temperature stability and can substitute for metallic cleaning agents. The lubricant or fuel composition containing the same is suitable as an internal-combustion engine lubricant or fuel capable of coping with future severe exhaust gas regulation.
