Zusammenfassung:	A low sediment process for forming a borated oil soluble polymer-substituted nitrogen- or ester-containing lubricating oil additive. A non-borated polymer-substituted nitrogen- or ester-containing additive in the presence of a solvent therefor, is contacted under boronating reaction conditions in a reaction zone with particulate boric acid. The boric acid has an average particle size distribution in lubricating oil characterized by a .slzero. value of not greater than about 450. The .slzero. value is the ratio of said particles' total spherical volume divided by said particles' total spherical external surface area.
