Description/Abstract This patent describes a process for preparation of an overbased alkali metal or alkaline earth metal petroleum oxidate additive for lubricants useful as a detergent, dispersant, and antirust friction modified.^It comprises: introducing into a reaction zone a petroleum oil, a base selected from the group consisting of an alkali metal compound or an alkaline earth metal compound to form a mixture, contacting the mixture with an oxidizing gas or compound at a temperature from about 40{degrees}F. to about 800{degrees} F. to effect oxidation of the petroleum oil and reaction of the base with the oxidized oil, followed by optionally filtering the mixture to separate the base reacted oxidized oil as a petroleum oxidate, carbonating the petroleum oxidate in the presence of a base selected from the group consisting of an alkali metal compound and an alkaline earth metal compound to form a reaction product comprising an overbased alkali metal or alkaline earth metal petroleum oxidate, optionally filtering the mixture to remove unreacted alkali metal compound or alkaline earth metal compound and stripping the overbased alkali metal or alkaline earth metal petroleum oxidate to remove water.
