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.
