An oil-based graphite lubricant for a plunger includes graphite that is used as a solid lubricant, and an organic bentonite swollen by a mineral oil and a surfactant that are used as a graphite dispersant. The lubricant is prepared by a method which includes a first step of causing an organic bentonite to swell in the mineral oil, a second step of adding a surfactant, and a third step of adding and dispersing graphite.
