A two-cycle oil additive composition and concentrate having improved detergency, lubricity and antiwear properties which more effectively controls deposits related to ring sticking comprising A) at least one dispersant prepared by reacting a carboxylic acid acylating agent with a polyalkylene polyamine and optionally a high molecular weight acylating agent; B) a second dispersant which is a succinimide such as prepared by acylating a polyalkylene polyamine with polyisobutylene succinic anhydride; and C) at least one polyolefin; at least one of the dispersants being a borated dispersant and which further optionally comprise at least one of the following: D) a sulfurized alkylphenol; and E) a phosphorous-containing antiwear agent.
A two-cycle oil additive comprising a dispersant (A) which is the reaction product of a polyalkylene polyamine, at least one monocarboxylic acid acylating agent and optionally at least one high molecular weight carboxylic acid acylating agent;
A two-cycle oil additive composition containing a two-cycle oil and from 5 to 60 volume percent of a two-cycle oil additive concentrate comprising a dispersant (A) which is the reaction product of a polyalkylene polyamine, at least one monocarboxylic acid acylating agent and optionally at least one high molecular weight carboxylic acid acylating agent;
A two-cycle oil concentrate comprising from:
