Abstract
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.
