Abstract: A LUBRICATING OIL COMPOSITION CONTAINING A HYDROCARBYL SUBSTITUTED AMINE ASHLESS DETERGENT WHERE THE HYDROCARBYL SUBSTITUENT CONTAINS AT LEAST 40 CARBON ATOMS, A POLYOXYALKYLENE DERIVATIVE, AND AN ALKALINE EARTH METAL CARBONATE DISPERSED IN THE OIL TO PROVIDE AN ALKALINITY VALUE OF ABOUT 10 MG. KOH/G. THESE COMPOSITIONS ARE FOUND TO BE HIGHLY RUST AND CORROSION INHIBITORY WHILE ALSO POSSESSING THE ABILITY TO REDUCE OR PREVENT THE FORMATION OF VARNISH, SLUGE AND DEPOSITS ON THE INNER METALLIC SURFACES OF INTERNAL COMBUSTION ENGINES. THE PREFERRED POLYOXYALKYLENE DERIVATIVES ARE THE POLYXYALKYENE POLYOLS OR OXAALKANOLS.
