  • Patent number: 6040279
    Abstract: A lubricant composition is disclosed that is suitable for direct fuel injected, crankcase-scavenged two-stroke cycle engines. That lubricant composition has a major amount of at least one oil of lubricating viscosity, a minor amount of a lubricity additive, a polyalkyl amide, an imidazoline, a polyisobutylene, and a functionalized polyisobutylene. The lubricity additive contains glycerol monooleate, an acid aliphatic aromatic amine-phosphate, and sodium sulfonate. The acid aliphatic aromatic amine-phosphate has a phosphorus/oxygen atom ratio of from 4.0:1 to 4.5:1, and at least 1.2 equivalents of acid to 1.0 equivalents of base.
    Type: Grant
