A lubricating oil composition with a resin (A) and a base oil (B), the resin (A) is in a range of 0.01 to 50 parts by mass per 100 parts of (A) and (B), the resin (A) satisfies the following requirements: (A-1) the resin (A) is a polymer including a constituent unit from 4-methyl-1-pentene in a range of 60 to 99 mol % and a constituent unit from an α-olefin having 2 to 20 carbon atoms (excluding 4-methyl-1-pentene) in a range of 1 to 40 mol % (provided that 4-methyl-1-pentene and the α-olefin is 100 mol %); (A-2) intrinsic viscosity [η] measured in decalin at 135° C. is in a range of 0.01 to 5.0 dl/g; (A-3) a melting point (Tm) is in a range of 110 to 150° C. as determined by DSC; and the base oil (B) has (B-1) kinematic viscosity at 100° C. is in a range of 1 to 50 mm2/s.
A lubricating oil composition comprising a resin (A) and a base oil (B), wherein the resin (A) satisfies the following requirements (A-1) to (A-3), the base oil (B) satisfies the following requirement (B-1), and a content ratio between the resin (A) and the base oil (B) is such that the resin (A) is in a range of 0.01 to 50 parts by mass per 100 parts by mass in total of the resin (A) and the base oil (B):
