Abstract: A lubricant composition for a compression-ignition internal combustion engine includes an amine and a detergent selected from metal sulfonates, phenates, salicylates, carboxylates, thiophosphonates, and combinations thereof. The lubricant composition has a TBN of from about 10 to about 100 mg KOH/g when tested according to ASTM D2896. The amine contributes from about 0.1 to about 28% of the TBN of the lubricant composition. Further, a method of lubricating an internal combustion engine with the lubricant composition includes the steps of injecting a fuel and the lubricant composition into a cylinder to form a mixture, and combusting the mixture via compression-ignition.

Abstract: A lubricant composition has an increased oxidation induction time. The lubricant composition includes a base oil present in an amount of greater than 85 parts by weight per 100 parts by weight of the lubricant composition. The lubricant composition also includes an antioxidant component including particular first, second, and third antioxidants.
