1. An engine oil comprising a major amount of a base oil selected from a Group II, Group III, Group IV and Group V base oil and mixtures thereof, wherein the Group II and Group III base oils have at least 90% saturates, and a minor amount of an additive package, wherein the additive package comprises:
(A) 0.1-2.0 wt.% of a friction modifier compound of the formula IV:wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl group having about 8 to about 22 carbon atoms; and
(B) at least one dispersant; and wherein the composition is adapted for use as a crankcase engine oil lubricant suitable for lubrication of at least pistons, rings, cylinders, bearings and crankshafts of an engine crankcase, and the engine oil composition has a phosphorus content of 50-1000 ppm.
