ABSTRACT:
This invention is directed to lubricating oil and functional fluid compositions having improved high temperature stability and which contain at least one phosphorus-containing composition and at least one oil-soluble nitrogen-containing composition. More particularly, the lubricating and functional fluid compositions of the present invention comprise (A) a major amount of an oil of lubricating viscosity, and a minor amount of (B-1) at least one soluble tertiary aliphatic primary amine salt of a substituted phosphoric acid composition characterized by the formula ##STR1## wherein R.sup.1 is hydrogen or a hydrocarbyl group, R.sup.2 is a hydrocarbyl group, and both X groups are either O or S, and (C) at least one soluble nitrogen-containing composition prepared by the reaction of a hydrocarbon-substituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid producing compound, of an amine containing at least one hydrogen attached to a nitrogen atom. Preferably, the amine salts of the phosphoric acids utilized in the lubricating compositions of the present invention are derived from primary amines, and the soluble nitrogen-containing compositions (C) also contain boron. The lubricating compositions of the present invention are particularly useful in gear applications requiring high thermal stability such as from about 160.degree. C. with intermittent operation up to about 200.degree. C.
