ABSTRACT The invention comprises a novel stabilizing system useful for imparting resistance to oxidative breakdown comprising: (1) a metal deactivator azine of the formula: where: R1 and R2 can be hydrogen; alkyl with 1 12 carbon atoms, alkoxy with 1-12 carbon atoms, carbalkoxy with 1-12 carbon atoms, halogen, hydroxy, nitro and amino groups and X1 and X2 can be hydrogen, alkyl with 1 12 carbon atoms or di-, tri- or tetramethylene bridges to the aromatic ring. (2) an amine; (3) a metal compound selected from the group consisting of metals or metal salt; and (4) a lubricating oil selected from the group consisting of polyester based oils, mineral oils or synthetic hydrocarbon oils. |
