Lubricant composition

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:
• 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;
• wherein R1 and R2 are independently selected from C1-20 branched or straight alkyl;
• 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;
• wherein R1, R2, and R3 are independently selected from C1-20 branched or straight alkyl;
• and
• 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%.
