ABSTRACT:
A process for incorporating molybdenum into overbased alkaline earth metal and alkali metal sulfonates, phenates and salicylates. The incorporation is a post addition of molybdenum into a previously prepared overbased composition. The resulting composition containing molybdenum is gel-free, haze-free, precipitate-free, has a reproducible Total Base Number (TBN) and is commercially acceptable for use in lubricating oil compositions.
