A grease composition is prepared from an isomerized base oil having consecutive numbers of carbon atoms and less than 10 wt% naphthenic carbon by n-d-M. In one embodiment, the isomerized base oil has a kinematic viscosity at 100°C. equal to or greater than 10 mm2/s. In another embodiment, the isomerized base oil has a cloud point - pour point spread of less than 25°C. The grease composition in one embodiment exhibits improved service life, i.e., capable of performing for longer period of time of at least 50% at high temperatures/speeds and in an oxidizing environment as compared to greases containing Group II or POA base oils in the prior art. |
