A lithium complex grease thickener for increasing the dropping point of a lubricating oil comprises as primary indgredients a lithium salt of 12-hydroxystearic acid or from alkyl esters thereof and a dilithium salt derived from dialky esters of terephthalic acid in a molar proportion of about 0.5 to 15:1. A lithium complex thickened grease of high lubricating activity, shear stability, penetration, water resistance and dropping point comprises a major proportion of a lubricating oil and about 1 to 45 wt % of the lithium complex thickener of this invention with respect to the thickened grease.
