    Abstract: Lubricating oil compositions containing less than about 0.1% by weight of phosphorus are described, and these lubricating compositions comprise a major amount of an oil of lubricating viscosity, and a minor amount of at least one oil-soluble sulfur-containing material which comprises the reaction product of sulfur and a Diels-Alder adduct in a molar ratio less than 1.7:1 wherein the adduct is an adduct of at least one dienophile with at least one aliphatic conjugated diene. Such lubricating oil compositions exhibit improved oxidation-corrosion-inhibiting properties, anti-wear properties, and/or extreme pressure properties. Such lubricating compositions also exhibit improved compatibility with nitrile seals.

    Abstract: Nitrogen-containing compositions made by condensing a nitro phenol with an organic amino compound having at least one hydrogen atom directly bonded to a nitrogen or oxygen atom are useful as additives for lubricants and fuels. A specific embodiment comprises compositions made by reacting nitro phenols having hydrocarbyl substituents of up to 750 aliphatic carbon atoms with alkylene polyamines.
