Beschreibung
Zusammenfassung:	This invention relates to a process for preparing an overbased metal salt of hydrocarbyl dithiophosphoric acid comprising neutralizing hydrocarbyl dithiophosphoric acid with an amount of metal oxide sufficient to form said over-based metal salt of hydrocarbyl dithiophosphoric acid, which metal oxide has a surface area of no less than 4 m 2 per gram up to 12 m 2 per gram.
