Combining a metal based friction modifier, such as a molybdenum dialkyldithiocarbamate, and certain esters of hydroxy carboxylic acids, such as short chain alkyl esters of citric or tartaric acid, e.g., tributyl citrate, has a synergistic effect on lowering the friction coefficient of lubricating oils allowing one to reduce the amount of metal based friction modifier needed to adequately formulate a lubricant with low friction characteristics.

The invention is directed to polyalphaolefins (PAOs) and processes for forming PAOs. In one embodiment, the invention is to a process for forming a PAO comprising polymerizing C-C&#x3b1;-olefin monomers in the presence of hydrogen, a C-Csaturated hydrocarbon, e.g., a C-Csaturated straight-chain hydrocarbon, and a catalyst system in a reaction vessel, wherein the C-Csaturated straight-chain hydrocarbon has about the same number of carbon atoms as the C-C&#x3b1;-olefin monomers. The C-Csaturated straight-chain hydrocarbon optionally is derived from a crude PAO product formed by the process of the invention. The invention is also directed to reaction systems for performing the processes of the invention, to processes for controlling PAO viscosity based on residence time, and to the removal of spent catalyst using a solid adsorbent particles.
