1. A lubricant composition comprising:
a base oil; and
at least one of carbon nanotubes with a diameter of 0.4 to 9.0 nm in an amount of 0.001 to 0.08% by mass relative to a total mass of the composition,
wherein the composition has a worked penetration measured according to JIS K2220 7 of 200 dmm to 440 dmm.
