A grease composition comprises an effective amount of a lubricating oil containing an imide or pyrrolidone thickening agent or an imide or pyrrolidone thickening agent comprising a metal salt of a carboxylic acid in combination with a bimetal phthalate complexing agent, such as dilithium terephthalate. The presence of the complexing agent results in a grease having properties superior to that of a similar grease without the complexing agent. Preferred complexing agents are dimetal terephthalates in which the metal is an alkali or alkaline earth metal and is the same metal as is present in the thickener. An example is a combination of a calcium or lithium salt of the reaction productof trimellitic anhydride with a hydrogenated rapeseed amine and a dilithium terephthalate complexing agent.

Composition de graisse comprenant une quantité efficace d'une huile lubrifiante contenant un agent épaississant à base d'imide ou de pyrrolidone ou un agent épaississant à base d'imide ou de pyrrolidone comprenant un sel métallique d'un acide carboxylique en combinaison avec un agent complexant à base de phtalate bimétallique, comme le téréphtalate de dilithium. La présence de l'agent complexant donne une graisse ayant des propriétés supérieures à celles d'une graisse semblable sans agent complexant. Les agents complexants préférés sont les téréphtalates bimétalliques dans lesquels le métal est un alcali ou un alcalino-terreux et est le même que celui qui est présent dans l'agent épaississant. Un exemple est une combinaison d'un sel de calcium ou de lithium du produit de réaction de l'anhydride triméllitique avec une amine de colza hydrogénée et l'agent complexant téréphtalate de dilithium.
