Abstract: This method for producing a lubricating oil composition includes: a step of dissolving fullerenes in a base oil mainly composed of a multiply alkylated cyclopentane oil or an ionic liquid containing an imide as a negative ion to obtain a fullerene solution; and a step of producing fullerenes adduct by subjecting the above-described fullerene solution to a heat treatment in a non-oxidizing atmosphere.
