ABSTRACT A blend of metal salts of hydrocarbyl substituted aromatic phosphorodithioic acids is disclosed. The blend of salts of the aromatic phosphorodithioic acids contain optitonally (A) high hydrocarbyl substituents, optionally (B) low hydro- carbyl substituents, and the high and the low hydro- carbyl substituent. Alternatively, the hydrocarbyl substituted substituents of an aromatic phosphoro- dithioic acid can be solely low but different hydrocarbyl derivatives. The (B) low hydrocarbyl phosphorodithioic acid component can be made utilizing mixtures of cresylic acids. These metal salts are oil-soluble and are useful as corrosion inhibitors and anti-wear agents, particularly in lubricating oil compositions.
