A storage-stable additive concentrate for formulating a lubricating oil composition is provided, the additive concentrate being derived from a dispersant and two or more surfactants in a colloidal hybrid wash. Contains agents. A lubricating oil additive concentrate comprising an oil having a lubricating viscosity of from about 30 to about 80% by weight and from about 20 to about 70% by weight of an additive, wherein from about 30 to about 90% of the additive. A hybrid overbased colloidal detergent based on active ingredient (AI) and derived from a sulfonate surfactant and a hydroxybenzoate surfactant; and (ii) a number from about 1,300 to about 2,500 daltons A polyalkene succinimide dispersant derived from a polyalkene having an average molecular weight (Mn) and the polyalkenyl succinimide dispersant (ii) in the lubricant additive concentrate to the hybrid overbased colloidal detergent (i) Is about 25: 1 to about 1: 1.
