A PROCESS FOR PRODUCING A LUBRICANT ADDITIVE WHICH COMPRISES PASSING CARBON DIOXIDE THROUGH A MIXTURE CONSISTING ESSENTIALLY OF A CALCIUM PETROLEUM SULFONATE MADE FROM A HIGHLY PARAFFINIC, DEASPHALTED AND SOLVENT REFINED PETROLEUM FRACTION HAVING A VISCOSITY OF 180 TO 230 SUS AT 210*F. AND HAVING A VISCOSITY INDEX OF AT LEAST ABOUT 85, A COMPOUND SELECTED FROM THE GROUP CONSISTING OF CALCIUM OXIDE AND CALCIUM HYDROXIDE IN AN AMOUNT BASED ON EQUIVALENT CALCIUM OXIDE IN THE RANGE OF 2 G. CALCIUM OXIDE PER 100 G. SULFONATE TO 80 G. CALCIUM OXIDE PER 100 G. OF MIXTURE, WATER IN THE RANGE OF 50 TO 1,000 PERCENT OF THE THEORETICAL AMOUNT NECESSARY TO CONVERT ALL OF THE CALCIUM COMPOUND EXPRESSED AS CALCIUM OXIDE TO CALCIUM HYDROXIDE, METHANL IN THE RANGE OF 10 G. PER 100 G. OF SULFONATE TO 150 G. PER 100 G. OF MIXTURE, ADN N-OCTANOL IN THE RANGE OF 2 TO 50 WEIGHT PERCENT OF THE TOTAL ALCOHOL PRESENT, THE MAXIMUM AMOUNT OF CALCIUM COMPOUND AND METHANOL BEING FURTHER LIMITED ACCORDING TO THE EQUATION CA(OH)2 = (350/(CH3OH - 37)) + 8 WHEREIN THE AMOUNTS ARE PARTS BY WEIGHT PER 100 PARTS OF MIXTURE.
