Abstract
An oleaginous corrosion-resistant lubricating composition comprising at least one poly-alpha olefin synthetic oil and effective amounts of metal salts of sulfonic acids, metal salts of carboxylic acids, metal salts of mixtures of said sulfonic and carboxylic acids, alkylated aromatic stabilizers as solubility modifiers, pour-point depressants, at least one antioxidant, triazole deactivator compounds and fluoroacrylate copolymers.
