Abstract: A lubricant composition includes a base oil and an additive package. The additive package includes a seal compatibility additive chosen from a halide seal compatibility additive, an epoxide seal compatibility additive, a boroxine seal compatibility additive, a sulfonate ester seal compatibility additive, and combinations thereof. The alkoxylated amide and the ester are set forth in general formulas A and B, respectively: In general formulas A and B, each R13, RII, RIII, and RIV, is, independently, a linear or branched, saturated or unsaturated, hydrocarbyl group. In addition, at least one of RII and RIII include an alkoxy group, and RIV includes an amine group.

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.
