Abstract
The present invention provides a novel cyclic phosphate such as 1,3-dioxa-2-phospha-6-thia-cyclooctane-2-(dodecylthiodi(ethyleneoxy)-2-oxi de, and its use as an anti-wear, anti-oxidant, and/or friction modifying agent for oleaginous compositions such as fuels, and lubricating oils particularly automatic transmission fluids. A new use of overbased metal phenates and/or sulfonates as friction stability promoters for conventional friction modifying agents is also provided.
