A lubricating oil additive for diesel engines comprising one or more members of carboxylic acids, metal salts of carboxylic acids, amine salts of carboxylic acids, and carboxylic acid amides, each having a substituted amino group or substituted amino groups in a molecule, wherein the substituted aminocarboxylic acid compounds have a function of dispersing water-containing calcium sulfate in an oil; and a lubricating oil composition for diesel engines including these lubricating oil additives for diesel engines. When the lubricating oil additives and the lubricating oil compositions for diesel engines of the present invention are added to the lubricating oil, the dispersion function of the water-containing calcium sulfate admixed in the lubricating oil is dramatically improved, and the dispersion functions in oil of the staining components, such as soots, sludges, and the like, mentioned above owned by the lubricating oil are enhanced, so that its detergency is dramatically improved. Therefore, it is made possible to lower the concentration in the amount of the metal-based detergent as well as to lengthen the service life of the lubricating oil.
