Abstract
A saturated aliphatic hydrocarbon compound composition having an evaporation loss of 4% by mass or less as determined by the Noack method, a kinetic viscosity at 100° C. of 6.5 mm2/s or less, and an average carbon number of 36 to 44. A lubricating oil composition may contain such a saturated aliphatic hydrocarbon compound composition. A method for producing a saturated aliphatic hydrocarbon compound composition, may include: (1) oligomerizing an olefin to obtain an olefin oligomer; (2) isomerizing the olefin oligomer to obtain an isomer; and (3) hydrogenating the isomer.
