Claim 1
Independent Claim
132 words
A LUBRICATING OIL COMPOSITION COMPRISING ABOUT 88 TO 99.99% BY WEIGHT OF A MINERAL BASE OIL OF LUBRICATING GRADE, 0.01 TO 5.0% OF THE REACTION PRODUCT OF A MONOCYCLIC TERPENE C10H16 TREATED FIRST WITH 25% TO 54% OF ITS WEIGHT OF SULFUR AT A TEMPERATURE RANGE BETWEEN 220* AND 400* F. FOR A PERIOD OF TIME SUFFICIENT TO SUBSTANTIALLY COMPLETE ITS SULFURIZATION AND TREATED THEREAFTER WITH 0.2 TO 10%, BASED ON THE WEIGHT OF THE SULFURIZED TERPENE, OF A PHOSPHOROUS SULFIDE AT A TEMPEATURE WITHIN THE RANGE OF 170* TO 350* F. FOR A PERIOD OF 1 TO 20 HOURS, AND 0 TO 10% OF AN EXTREME PRESSURE ADDITIVE SELECTED FROM THE GROUP CONSISTING OF CHLORINATED AND SULFURIZED LONG CHAIN HYDROCARBONS, SULFURIZED AND PHOSPHORIZED FATTY OILS, AND SULFURIZED AND PHOSPHORIZED ALIPHATIC ESTERS.
