The present invention relates to a lubricant additive concentrate comprising about 30 to about 90% by mass of lubricant viscosity oil and about 20 to about 70% by mass of an additive, wherein about 30 to about 90% by mass of the additive comprises: (i) a hybrid overbased colloidal cleaner derived from a sulfonate surfactant and a hydroxybenzoate surfactant; and (ii) a poly alkenyl succinimide dispersant derived from a polyalkene having a number average molecular weight (Mn) of from about 1,300 to about 2,500 Daltons. The mass ratio of (i) the hybrid overbased colloidal cleaner to (ii) the poly alkenyl succinimide dispersant is about 25:1 to about 1:1. 본 발명은 약 30 내지 약 80 질량%의 윤활 점도 오일 및 약 20 내지 약 70 질량%의 첨가제를 포함하는 윤활유 첨가제 농축물로서, 이때 상기 첨가제의 약 30 내지 약 90 질량%는, (i) 설포네이트 계면활성제 및 하이드록시벤조에이트 계면활성제로부터 유도된 하이브리드 과염기성 콜로이드성 세정제; 및 (ii) 약 1300 내지 약 2500 달톤의 수 평균 분자량(Mn)을 갖는 폴리알켄으로부터 유도된 폴리알켄일 석신이미드 분산제를 포함하고, 상기 윤활유 첨가제 농축물 중의 폴리알켄일 석신이미드 분산제(ii) 대 하이브리드 과염기성 콜로이드성 세정제(i)의 질량비는 약 25:1 내지 약 1:1이다.
