Methods, a lubricant composition, and a fuel composition for lubricating a two-stroke internal combustion engine include a lubricant composition that contains (A) an oil of lubricating viscosity, (B) an additive composition comprising a condensation product of a fatty acid with an amine or ammonia and a further dispersant, and (C) a normally liquid solvent having a kinematic viscosity of less than 5 cSt at 100°C. The lubricant composition improves the cleanliness of a power valve of a two-stroke engine. |
