An anticorrosive oil composition comprising: at least one base oil selected from the group consisting of a mineral oil and a synthetic oil both having a 5% distillation temperature of 140 to 250 DEG C inclusive, a 95% distillation temperature of 250 DEG C or lower, a difference between the 5% distillation temperature and the 95% distillation temperature of 90 DEG C or lower, an aromatic component content of 5 vol% or less, a naphthene content of 30 to 95 vol% inclusive, a density of 0.75 g/cm3 or more at 15 DEG C, and a kinematic viscosity of 0.3 to 5.0 mm2/s inclusive at 40 DEG C; at least one base oil selected from the group consisting of a mineral oil and a synthetic oil both having a 5% distillation temperature of 260 DEG C or higher and a kinematic viscosity of 6.0 to 500 mm2/s inclusive at 40 DEG C; and an anticorrosive additive.
