Abstract:
    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 are included in the description. The lubricating compositions of the present invention are particularly useful in gear applications requiring high thermal stability such as from about 160 DEG C with intermittent operation up to about 200 DEG C.
