Lubricating oils exhibiting anti rust properties are obtained by adding to the lubricating oil an acidic anti rust additive and an acid scavenger such as carbodiimide, in a specific sequence.

Method for producing lubrication oils possessing anti rust properties containing acidic anti rust additive and acid scavengers

A lubricating oil formulation containing a major amount of a base oil of lubricating viscosity and a minor amount of additives comprising a combination of phenyl naphthyl amine, dimercaptothiadiazole or derivative thereof, and triazole or benzotriazole or derivative thereof, exhibiting enhanced resistance to oxidation.

Industrial oils of enhanced resistance to oxidation

Lubricating oils of enhanced oxidation stability are obtained by adding to the lubricating oil a mixture comprising n-phenyl-1-naphthyl amine and an acid scavenger such as carbodiimide.

Lubricating oils of enhanced oxidation stability containing

A lubricant composition especially useful for saw guide use comprises a base oil composed of at least one synthetic ester and a thickener composed of a styrene-olefin copolymer dissolved in a vegetable oil. The thickener is present in an amount sufficient to provide the lubricant with a viscosity at 40.degree. C. of greater than about 100 cSt.
