    Abstract: A method of increasing the total base number of a metal petroleum sulfonate additive which involves recontacting the once carbon dioxide-contacted mixture with carbon dioxide under substantially the same conditions employed in the original carbon dioxide contacting. The carbonation is carried out on a discontinuous liquid phase of the additive which is in admixture with an inorganic base and with methanol.
