摘要： A method for producing a lubricating oil composition includes: a step of mixing a base oil and fullerene, dissolving a soluble component of the fullerene in the base oil, and obtaining a mixture of the base oil and fullerene; a step of removing an insoluble component included in the mixture and obtaining a fullerene solution; and a step of heat-treating the fullerene solution.

摘要： A method for inspecting a lubricant oil composition containing a base oil and a fullerene, the method including: measuring at least one of a lamellar length of the lubricating oil composition and a most abundant diameter in a particle size distribution obtained by a dynamic light scattering method, and selecting the lubricating oil composition whose measured value is within a set range.
