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.

A method for producing a lubricating oil composition, comprising:
- 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 configured to obtain a fullerene solution;
- and
- a step of producing fullerene adducts by subjecting the fullerene solution to a heat treatment in a non-oxidizing atmosphere.
The lubricating oil composition comprising:
- a base oil mainly composed of a multiply alkylated cyclopentane oil or an ionic liquid containing an imide as a negative ion;
- and
- fullerene adducts obtained by adding a component derived from the base oil to fullerenes.
