Abstract: This disclosure describes a lubricant additive. The additive is a friction modifier that includes a molybdenum containing compound and a tertiary amine-containing composition having the structure (I), wherein each R1 and R5 is independently a linear or branched-chain monovalent hydrocarbyl group having one to about twenty carbon atoms, wherein each R2, R3, and R4 is independently a hydrogen, a linear or branched-chain monovalent hydrocarbyl group having one to about twenty carbon atoms, each m is independently from 0 and 4, each p is independently from 0 and 4, for each cyclic moiety m + p is from 2 and 4, and each n is independently from 1 and 6.

Abstract: Provided is a lubricating oil composition having a HTHS viscosity at 150°C in a range of about 1.7 to about 3.2 mPa s and a low temperature cold cranking viscosity of less than 7,000 mPa s at -20 °C, comprising: (a) a major amount of an oil of lubricating viscosity having a kinematic viscosity at 100°C of from 3.5 mm 2 /s to 20 mm 2 /s and a viscosity index of greater than 120 with a sulfur content of less than 0.03 wt.%, are classified into the API group III, IV, or V base stock category, and have an aromatics content (C A ) of less than 5%; (b) an organomolybdenum compound; (c) a dispersed hydrated alkali metal borate compound; (e) one or more dispersants; (f) one or more calcium-based metal detergents; and (g) optionally, one or more magnesium-based metal detergents. Also provided is a method for improving wear, high temperature detergency, and thermal stability in an engine comprising operating said engine with said lubricating oil composition.
