Abstract
Novel friction reducing additives provide friction modification at a lower effective concentration when added to a motor oil base. A friction reducing motor oil composition may include motor oil base and a friction reducing additive having the structure of the general formula (I): wherein: R1 is a straight or branched C5-C30 alkyl or alkenyl; R2 is H, or a straight or branched alkyl of C1-C10; R3 is H, or a straight or branched alkyl of C1-C10; P is 0 or C1; n is C1-C5; and m is C0-C5.
