ABSTRACT:
This invention relates to a two-cycle engine lubricant composition, comprising (A) at least one dispersant, (B) at least one reaction product of a fatty acid and a polyamine, and (C) at least about 25% by weight of the composition of at least one varnish dissolver selected from (a) keto-alcohols, (b) carboxylic esters having up to a total of 24 carbon atoms and (c) alkoxy alcohols, and (D) at least about 15% by weight of the composition of at least one fluidizing oil, and a method, comprising the steps of introducing into a two-cycle internal combustion engine a fuel-lubricant mixture comprising a major amount of a fuel and a minor amount sufficient to increase compression or release stuck piston rings, of the two-cycle engine lubricant composition.
