| Zusammenfassung: | A lubricating oil composition comprising:
(a) a base oil selected from Group III base oils, polyalphaolefins, and mixtures thereof;
(b) 0.3 wt% or less of sulphur; and
(c) 30 wt% or less of viscosity modifier;
wherein the lubricating oil composition has a kinematic viscosity at 40°C in the range of from 2 mm 2 /s to 220 mm 2 /s and wherein the lubricating oil composition provides a weld load of 150 Kg or greater in the 4 ball weld load test (ASTM D2596). The lubricating oil composition of the present invention provides improved anti-wear and improved extreme-pressure properties. |
