The grease composition is prepared from an isomerized base oil having a continuous number of carbon atoms and less than 10% by weight naphthenic carbon by ndM. In one embodiment, the isomerized base oil has a kinematic viscosity at 100 ° C. of 10 mm 2 / sec or more. In another embodiment, the isomerized base oil has a cloud point-pour point width of less than 25 ° C. The grease composition in one embodiment exhibits improved service life, i.e., at least 50% longer than greases containing Group II or POA base oils in the prior art in high temperature / high speed and oxidizing environments. Period driving is possible. |
