Disclosed is a low-phosphorous lubricant produced by a process comprising forming a lubricant additive by reacting metal halide and organophosphate together to form a reaction mixture, the metal halide participating as a reactant, and adding at least a portion of the reaction mixture to a lubricant base comprising from about 0.01 weight percent phosphorous to about 0.1 weight percent phosphorous.


1. A lubricant produced by the process comprising: forming a lubricant additive by reacting a metal halide with a pentavalent, mono- or di-thiophosphate to form a reaction mixture, the metal halide participating as a reactant so that at least one compound is formed having a phosphorus-fluorine bond, wherein the metal halide is selected from the group consisting of aluminum trifluoride, zirconium tetrafluoride, titanium trifluoride, titanium tetrafluoride, ferric fluoride, chromium difluoride, chromium trifluoride, nickel difluoride, stannous difluoride, ...
