ABSTRACT:
The invention relates to a two-cycle oil additive, compositions and concentrates containing said two-cycle oil additive and methods of preparing and using the two-cycle oil additive which comprises the reaction product of (A) at least one high molecular weight acylating agent (B) at least one polyalkylenpolyamine and (C) at least one monocarboxylic second acylating agent, wherein the molar ratio of the carboxylic acid acylating agent to the high molecular weight acylating agent is at least 3:1 and wherein the tertiary amine to total amine ratio of the reaction product is at least 0.7:1. The two-cycle oil additive of the invention are dispersant additives which will improve engine cleanliness and which will substantially avoid the formation of insoluble gel agglomerants at low temperatures which can adversely affect engine performance.
