摘要： An additive concentrate suitable for incorporation into a finished lubricating oil composition is disclosed. The additive concentrate comprises:(a) a lubricating oil, and(b) a lubricating oil soluble sulphurized or non-sulphurized alkaline earth metal hydrocarbyl phenate modified by incorporation from 2 to less than 40% by weight based on the weight of said concentrate of either (i) at least one carboxylic acid having the formula: ##STR1## wherein R is a C.sub.10 to C.sub.24 alkyl or alkenyl group and R.sup.1 is either hydrogen, a C.sub.1 to C.sub.4 alkyl group or a --CH.sub.2 --COOH group, or an anhydride, acid chloride or ester thereof or (ii) a di- or polycarboxylic acid containing from 36 to 100 carbon atoms or an anhydride, acid chloride or ester thereof, said concentrate having a TBN greater than 300, and a viscosity at 100.degree. C. of less than 1,000 cSt. A process for making the foregoing concentrate is disclosed. A finished lubricating oil composition containing the foregoing concentrate is also disclosed.
