During his tenure at the Cities Service Oil Co. in the late ’60s, Ernest J. Jamieson patented four inventions on the improvement of current gasoline compositions. One invention improved hydrocarbon fuel compositions for use in internal combustion engines by adding a detergent that prevents icing and corrosion.
Another invention improved a hydrocarbon fuel composition by adding a X hydrocarbylacid phosphate salt that reduced icing in the carburetor and improved water tolerance, thus reducing rust and hydrocarbon content in the exhaust.
