LUBRICATING COMPOSITION

摘要

The present invention provides a lubricating composition comprising a base oil and one or more additives, wherein the composition has: - a dynamic viscosity at -30°C (according to ASTM D 5293) of below 6600 cP; - a kinematic viscosity at 100°C (according to ASTM D 445) of at least 9.3 cSt; - a high temperature, high shear viscosity ("HTHS"; according to ASTM D 4683) of at least 2.9 cP; - a Noack volatility (according to ASTM D 5800) of below 14 wt.%; wherein the base oil has a kinematic viscosity at 100°C (according to ASTM D 445) of at least 4.8 cSt.
