Abstract: Disclosed is an additive composition for lubricants, which can be prepared easily and is composed of a phosphorus-containing compound metal salt. The additive composition for lubricants has no adverse effect on rubber sealings such as swelling, while having excellent storage stability. Specifically disclosed is an additive composition for lubricants, which is characterized by blending, based on the total amount of the composition, 10-90% by mass of a metal salt of a phosphorus-containing compound represented by general formula (1) (wherein X4-X7 respectively represent an oxygen or sulfur atom, with at least one of X4-X7 being an oxygen atom; and R1-R3 respectively represent a hydrogen atom or a hydrocarbon group having 3-18 carbon atoms, with at least one of R1-R3 not being a hydrogen atom) into a lubricant base oil which is selected from mineral oils, synthetic oils and mixtures thereof, and has a kinematic viscosity at 100°C of 0.5-3 mm2/s, a %CA of not more than 3, and a sulfur content of not more than 0.05% by mass.
