1. A lubricant composition for a compression-ignition internal combustion engine, said lubricant composition comprising:
(A) an amine selected from the group consisting of (I), (III), and (IV) defined as follows:

OG Complex Work Unit Chemistry
wherein each of R1 to R9 are independently selected from a hydrogen, a C1-6 branched or straight alkyl or a halogen; and
R10 is selected from hydrogen, hydroxy or a C1-20 branched or straight alkyl;

OG Complex Work Unit Chemistry
wherein R1 and R2 are independently selected from C1-20 branched or straight alkyl;

OG Complex Work Unit Chemistry
wherein each of R1 and R2 are independently selected from a hydrogen, a C1-6 branched or straight alkyl or a halogen; m and y are independently an integer of 1 to 6 and n is 1 to 7;

OG Complex Work Unit Chemistry
wherein R1, R2, and R3 are independently selected from C1-20 branched or straight alkyl; and

OG Complex Work Unit Chemistry
wherein R1 to R4 are independently selected from hydrogen and a C1-6 alkyl and m is an integer of 1-12; and
(B) a detergent selected from metal sulfonates, phenates, salicylates, carboxylates, thiophosphonates, and combinations thereof,
wherein a TBN of said lubricant composition is from about 10 to about 100 mg KOH/g when tested according to ASTM D2896; and
wherein a TBN contribution of said amine to said TBN of said lubricant composition is from about 0.1 to about 28%.
