The second thickener component may be, for instance, polyurea, a metallic soap, a complex metallic soap or an N-substituted terephthalamic acid metal salt. Alternatively, a grease composition with a thickener of an N-substituted terephthalamic acid metal salt and a second thickener component in a base oil. Furthermore, a grease composition with a thickener component of polyurea and complex metallic soap in an ester oil. Still further, a grease composition with a thickener of polyurea and a complex metallic soap in a base oil. |
