Title:
LUBRICATING COMPOSITION
Document Type and Number:
Japanese Patent JP2010189639
Kind Code:
A
Abstract:
To provide an alternative lubricating composition which particularly satisfies stringent conditions of kinematic viscosity (at elevated temperature) and Brookfield viscosity (at cold temperature) and is used as a transmission fluid.
The lubricating composition comprises a base oil, which comprises a Fischer-Tropsch derived base oil, and one or more additives, has at least 3.6 cSt kinematic viscosity at 100°C (according to ASTM D445), <10,000 mPa s Brookfield viscosity at -40°C (according to DIN51398) and comprises a VI improver of <1.0 wt.% based on the total weight of the lubricating composition.
