Appeal No. 1997-3770 Application No. 08/451,888 THE INVENTION The invention is directed to a lubricating composition containing a major amount of a lubricating oil, and the combination of a group of additives to improve the antiwear properties of the lubricating composition. THE CLAIMS Claim 1 is illustrative of appellants’ invention and is reproduced below. 1. A lubricating composition comprising a major amount of an oil of lubricating viscosity and (A) an antiwear improving amount of at least one molybdenum containing composition, and (B) at least one member selected from the group consisting of (i) at least one borated overbased metal salt of an acidic organic compound, provided that (A) and (Bi) are not the same, (ii) a combination of (a) at least one organic polysulfide or at least one ashless dithiocarbamate containing composition and (b) at least one component selected from the group consisting of a metal thiophosphate, a phosphoric acid ester or salt thereof, a phosphorus-containing carboxylic acid, ester, ether, or amide, a borated dispersant, an alkali metal borate, a borated fatty amine, a borated phospholipid, a borate ester, and mixtures thereof, and (iii) a combination of (i) and (ii) provided that when (A) is a molybdenum dithiophosphate, then (A) is present in an amount to provide from about 125 to about 900 ppm molybdenum to the lubricating composition. 2Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
