Abstract: Hydrocarbyl acid phosphate salts of polyamides having at least one amino group and hydrocarbon fuel compositions containing same. The salts are formed by neutralizing with a hydrocarbyl acid phosphate at least 10 percent of the amino groups of a polyamide containing from about 2 to about 6 amide groups and at least one amino group. Hydrocarbon fuel compositions containing these salts exhibit desirable properties such as enhanced carburetor detergency and carburetor anti-icing characteristics, improved water tolerance, excellent rust inhibition, and cleaner engine operation while engines operated thereon exhibit reduced hydrocarbon content in the exhaust.
