Lubricating compositions

A liquid composition formulated to provide enhanced lubrication and anti-wear properties under extreme pressure conditions, the composition comprising:

• from about 0.25% by weight and up to about 6% by weight of a liquid molybdenum complex, wherein the liquid molybdenum complex comprises an oil-soluble molybdenum salt selected from the group consisting of molybdenum alkyl dithiophosphate, molybdenum alkyl dithiocarbamate, and any combination thereof;
• up to about 10% by weight of a molybdenum activator, wherein the molybdenum activator comprises two or more sulfurized lubricant additive compounds, the two or more sulfurized lubricant additive compounds selected from the group consisting of:
• a sulfurized methyl ether;
• a sulfurized fat;
• a sulfurized olefin;
• an alkyl dithiocarbamate;
• an alkyl dithiophosphate;
• an alkyl dimercaptothiadiazole;
• and any combination thereof;
• and
• up to about 5% by weight of liquefacted boron nitride, the liquefacted boron nitride prepared from the solvation of exfoliated solid boron nitride within a liquid carrier,
• wherein the composition is homogeneous and has no visible suspended or settled particles, and
• wherein the balance is a base oil.

A liquid additive composition formulated for addition to a base oil to provide enhanced lubrication and anti-wear properties under extreme pressure conditions, the composition comprising:

• up to about 90% by weight of a liquid molybdenum complex, wherein the liquid molybdenum complex comprises an oil-soluble molybdenum salt selected from the group consisting of molybdenum alkyl dithiophosphate, molybdenum alkyl dithiocarbamate, and any combination thereof;
• and
• up to about 80% by weight of liquefacted boron nitride, the liquefacted boron nitride prepared from the solvation of exfoliated solid boron nitride within a liquid carrier,
• wherein the composition is homogeneous and has no visible suspended or settled particles.
