Case EI-6336 OIL ADDITIVE CONCENTRATES AND LUBRICANTS OF ENHANCED PERFORMANCE CAPABILITIES Abstract of the Disclosure Haze formation in additive concentrates containing boron- containing ashless dispersants is inhibited, and improvements in performance capabilities can be realized, by suitably controlling the pH of the concentrate as produced. Not only does such pH control result in no sacrifice in wear and corrosion inhibition, but it has been found possible by suitable adjustment and control of pH to actually improve the effectiveness of the concentrate in its ability to inhibit wear and corrosion. Moreover, such pH control makes possible the provision of compositions having enhanced extreme pressure properties as seen in the standard L-42 test, and improved antirust performance as seen in the standard L- 33 test.
