Abstract
A lubricant suitable for lubricating a two-stroke cycle engine which is fueled with a liquid fuel having a volatility less than that of gasoline comprises an oleaginous synthetic ester, a normally liquid solvent having a kinematic viscosity of less than about 5 or 2 mm/s at 100° C. and a nitrogen-containing dispersant bearing a hydrocarbyl group of at least 26 carbon atoms and having a nitrogen content of at least 4 percent by weight. The nitrogen content of the lubricant is at least about 0.3 percent by weight.
