    Abstract: In lubrication of an internal combustion engine equipped with a cooled exhaust gas re-circulation (EGR) system, a lubricant containing a minor amount of a dispersant is circulated through a lubricating system so that the dispersant forms salts with combustion acids therein, and the lubricant is then contacted with an, immobilised base, more strongly basic than the dispersant, that displaces the dispersant from the salts to form retained base: combustion acid salts and release the dispersant into the lubricant. The EGR system does not include a chemical filter and re-circulating exhaust combustion gases are chemically unfiltered.
