Abstract: Lubricating oils containing borated fatty acid esters of glycerol-succinimide complex have been found to reduce fuel consumption in an internal combustion engine.

Abstract: Oil-insoluble zinc salts of cyclic dithiophosphates are rendered oil soluble when combined to form a complex with alkenyl or alkyl mono- or bis-succinimides. Oil compositions containing this combination are useful as crankcase lubricants.

Abstract: Lubricating oils containing oil soluble C.sub.10 -C.sub.30 alkane-1,2-diols have been found to reduce fuel consumption in an internal combustion engine.

Abstract: Lubricating oils containing oil soluble C.sub.8 -C.sub.28 alkane-1,2-diols have been found to reduce brake noise for oil-immersed disc brakes.

Abstract: Disclosed is a novel composition formed from the reaction of (a) an alkylphenol; (b) sulfur; (c) an alkaline earth metal and (d) an olefin. The composition is useful as a lubricating oil additive and provides both oxidation and corrosion control.

Abstract: Disclosed is a lubricating oil additive composition which imparts improved oxidation properties to internal combustion engine crankcase lubricants which comprises:(1) an antioxidant selected from aromatic or alkyl sulfides and polysulfides, sulfurized olefins, sulfurized carboxylic acid esters and sulfurized ester-olefins, and(2) an oil-soluble chlorinated hydrocarbon containing at least 6 carbon atoms.Lubricating oil compositions containing this additive composition are also disclosed. Particularly preferred are compositions which also contain an oil-soluble zinc salt.

Abstract: Group II metal mixed salts of: (A) an oil-soluble hydrocarbyl sulfonic acid; and (B) a polyoxyalkylenated sulfuric acid are useful as rust inhibitors in lubricating oil compositions.

Abstract: A lubricating oil composition of improved rust-inhibitory capability contains a small amount of a sulfated alcohol having a molecular weight in the range of 500 to 5,000 which is prepared by reacting an aliphatic alcohol or a phenol with ethylene oxide or propylene oxide or mixtures thereof to form a polyoxyalkenylated alcohol which is treated with sodium hydride, potassium, sodium, sodium methoxide, potassium methoxide or potassium tert-butoxide and then is sulfated by treating with chlorosulfonic acid.

Abstract: A lubricating oil composition of improved rust inhibitory capability contains a small amount of the sulfate of an oxyalkylenated alcohol or phenol having a molecular weight of about 500-5,000.
