(57) [Summary]nA high wear resistant synthetic lubricant comprises a synthetic isoparaffinic hydrocarbon base oil and an effective amount of at least one antiwear agent. The antiwear agent is preferably at least one of a metal phosphate, a metal dialkyldithiophosphate, a metal dithiophosphate, a metal thiocarbamate, a metal dithiocarbamate, an ethoxylated amine dialkyldithiophosphate, and an ethoxylated amine dithiobenzoate. Metal dialkyldithiophosphates, particularly zinc dialkyldithiophosphate (ZDDP), are preferred. A base oil comprising a process comprising hydroisomerization of a feedstock and dewaxing of an isomerate from a waxy Fischer-Tropsch synthetic hydrocarbon feedstock containing a hydrocarbon having an initial boiling point in the range of about 650-750 ° F. Induced by The lubricant may also include hydrocarbonaceous and synthetic base oil materials as a mixture with a Fischer-Tropsch derived base oil. |
