Abstract:
1. A lubricant composition for a two-cycle engine comprising: (a) an oil of lubricating viscosity; (b) about 3.0 to about 25 percent by weight of a synthetic ester that comprises: an ester derived from pentaerythritol; (c) about 3.7 to about 7.2 percent by weight of a Mannich dispersant prepared from an alkylene diamine and formaldehyde or a reactive equivalent thereof; (d) about 1.5 to about 2.1 percent by weight of at least one condensation product of a fatty acid with a polyamine, where the fatty acid comprises isostearic acid and the polyamine comprises a polyalklyenepolyamine, and (e) a normally liquid solvent having a kinematic viscosity of less than 5 cSt at 100° C.; and wherein the nitrogen content of the lubricant composition is about 0.1 to about 0.25 percent by weight.
