Abstract
A lubricant composition suitable for lubricating an internal combustion engine comprises: (a) an oil of lubricating viscosity having a viscosity index of at least 105 and a kinematic viscosity at 100 C of less than 7 mm2s-1; (b) 0.01 to 2 weight percent of a friction modifier represented by the structure [I]; (c) 0.5 to 4 weight percent of a poly(meth)acrylate viscosity modifier polymer; (d) 0 to 500 parts per million by weight of molybdenum in the form of an oil-soluble molybdenum compound; and (e) 0 to 200 parts per million by weight of boron in the form of an oil-soluble boron compound.
