Abstract: Described are lubricating greases corrosion inhibited by a synergistic amount of a mixture of sodium nitrite and N-acyl sarcosines.The greases contain from 75 to 96 parts by weight, preferably 80 to 95 parts by weight of a mineral oil having a SUS viscosity of 50 to 2500 at 100.degree. F thickened to grease consistency with about 3 to 25, preferably 5 to 20, parts by weight of an alkali metal or alkaline earth metal soap or a mixture thereof.
