Beschreibung
Zusammenfassung:	A lubricating oil composition comprising (A) an ethylene/±-olefin copolymer satisfying all of the following requirements (A-1) to (A-3) : (A-1) an ethylene structural unit content of 30 to 70% by mol, (A-2) a kinematic viscosity at 100°C of 20 to 3000 mm 2 /s, and (A-3) Mw/Mn as measured by GPC of 1 to 2.5, (F) a sulfur-containing compound in which at least one hydrocarbon group adjacent to sulfur is a secondary or tertiary hydrocarbon group, and as an optional component, (G) an ±-olefin polymer having 3 to 6 carbon atoms, and having a kinematic viscosity at 40°C of 450 to 51,000 mm 2 /s, a sulfur content of 0.1 to 5 parts by weight, and a component (G) content of 0 to 15 parts by weight. The lubricating oil composition is suitable particularly for gear oil and the like.
