PROBLEM TO BE SOLVED: To provide an oily lubricant composition which is hard to burn even at a high temperature, does not pollute the work environment, can produce a high-quality cast product, has a sufficiently low frictional force without using graphite as a solid lubricant, and is excellent in lubrication performance. SOLUTION: The oily lubricant composition for plungers includes a base oil component, a solid lubricant excluding graphite, and an anti-wear agent containing zinc dithiophosphate.
