Definitions

  • the base oil used in the present invention may conveniently comprise mixtures of one or more mineral oils and/or one or more synthetic oils; thus, the term "base oil” herein may refer to a blend containing more than one base oil.
  • a preferred Fischer-Tropsch derived base oil for use herein has a pour point (as measured according to ASTM D 5950) of below -30°C, more preferably below -40°C, and most preferably below -45°C.
  • Fischer-Tropsch derived base oil contains a blend of two or more Fischer-Tropsch derived base oils
  • the above values apply to the blend of the two or more Fischer-Tropsch derived base oils.
  • the total amount of base oil incorporated in the lubricating oil composition of the present invention is preferably in the range of from 60 to 99 wt.%, more preferably in the range of from 65 to 90 wt.% and most preferably in the range of from 70 to 85 wt.%, with respect to the total weight of the lubricating oil composition.
  • R 5 and R 6 each represent a hydrocarbon group having 1 to 20 carbon atoms.
  • the thiadiazole compound include 2,5-bis(n-hexyldithio)-1,3,4-thiadiazole, 2,5-bis(n-octyldithio)-1,3,4-thiadiazole, 2,5-bis(n-nonyldithio)-1,3,4-thiadiazole, 2,5-bis-(1,1,3,3-tetramethylbutyldithio)-1,3,4-thiadiazole, 3,5-bis(n-hexyldithio)-1,2,4-thiadiazole, 3,5-bis(n-octyldithio)-1,2,4-thiadiazole, 3,5-bis(n-nonyldithio)-1,2,4-thiadiazole, 3,5-bis(1,1,3,3-tetramethylbutyldithio)-1,2,4-thiadiaadia
  • the thiocarbamate compound may include a metal-containing thiocarbamate or an ashless (non-metal-containing) thiocarbamate. Suitable examples include a zinc dialkyldithiocarbamate and 4,4'-methylene-bis-dibutyldithiocarbamate.
  • Boron-containing compounds that may be conveniently used include borate esters, borated fatty amines, borated epoxides, alkali metal (or mixed alkali metal or alkaline earth metal) borates and borated overbased metal salts.
  • seal fix or seal compatibility agents include, for example, commercially available aromatic esters.
