Additive compositions with plural friction modifiers

A lubricating oil comprising a major amount of base oil and a minor amount of an additive package, wherein the additive package comprises:

• (A) one or more reaction products of one or more compounds 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 the hydroxyl moiety on the acid group may be replaced by a suitable leaving group, if desired, prior to the reaction;
• and
• one or more amines of the Formula V:
• wherein R2, R3, and R4 are independently selected from hydrogen, C1-C18 hydrocarbyl groups, and C1-C18 hydrocarbyl groups containing one or more heteroatoms;
• and
• (B) at least one friction modifier that is different from the one or more compounds (A) and which comprises at least one compound selected from alcohols, glycerol esters, amines, ethoxylated amines, amides, ethoxylated amides, dimer acids, polyesters, zinc dithiocarbamates, molybdenum dithiocarbamates, and sulfur-free molybdenum compounds.
