A lubricating composition of about 90 to about 99% by weight of a lubricant and about 1 to about 5% by weight of an organometallic phthalocynaine, preferably a polymeric organometallic phthalocyanine complex, including nitrogen-substituted analogues thereof, where the complexed metal ion is preferably a Group IVA metal and provides increased time of machine operation to failure by improving oil lubricated bearing performance. Phthalocynanine peripheral ring substituents and attached to the phthalocyanine increase solubility in aqueous and organic lubricants.

Phthalocyanine complex-filled fluids

A lubricating composition of about 90 to about 99% by weight of a lubricant and about 1 to about 5% by weight of a polymeric organometallic phthalocyanine complex, including nitrogen-substituted analogues thereof, where the complexed metal ion is preferably a Group IVA metal and provides increased time of machine operation to failure by improving grease or oil lubricated bearing performance. The phthalocyanine is doped with an electrically conductive dopant to bleed internal charge build up from the internals of turbines and large drive motors.
