Abstract:
A two-cycle engine fuel composition comprising (a) a major amount of a two-cycle engine fuel; (b) a lubricant component; and, (c) a two-cycle engine fuel combustion deposit-inhibiting amount of at least one hydrocarbyl polyoxyalkylene aminoalcohol of the general formula wherein R1 is an alkyl, an alicyclic or an alkylalicyclic radical having from about 4 to about 30 carbon atoms or an alkylaryl where the alkyl group is from about 4 to about 30 carbon atoms; x is an integer from 0 to about 5, y is an integer from 1 to about 49, z is an integer from 1 to about 49 and the sum of x+y+z is equal to 3 to about 50; R2 and R3 each is different and is an alkyl group of from 1 to 4 carbon atoms and each oxyalkylene radical can be any combination of repeating oxyalkylene units to form random or block copolymers; R4 is the same as R2 or R3; R5 is hydrogen or where R7 is hydrogen or an alkyl group of from 1 to 5 carbon atoms and R6 is hydrogen or an alkyl group of from 1 to 5 carbon atoms and methods for using same are provided.
