A lubricating oil composition, containing a base oil (A), a metal-based detergent (B), and a molybdenum compound (D), the lubricating oil composition having a content of molybdenum atoms derived from the molybdenum compound (D) of 0.05% by mass or more, a base number of 4.0 mg KOH/g or more, and an HTHS viscosity at 150° C. of 1.3 mPa.Math.s or more and less than 2.3 mPa.Math.s.

This disclosure describes lubricating additives and lubricants including such additives suitable for and/or configured for mixed fleet use and, for instance, additives and lubricants that satisfy performance standards for typical spark ignition passenger car lubricants as well as performance standards for lubricants suitable for typical compression ignition heavy duty engine applications.

A lubricating oil composition which contains a base oil and a fluorine compound and may have improved cooling performance. The base oil may contain a mineral oil. The base oil may have a kinematic viscosity in a range of from 1 to 25 mm.sup.2/s at 40° C. The content of the fluorine compound may be in a range of from 3 to 30% by weight based on the total amount of the composition.

The present disclosure describes lubricant compositions effective to reduce lead corrosion through an admixture of lubricant additives including at least a base oil of lubricating viscosity, a dispersant, a friction modifier, and boron-containing compound.

The present invention relates to the use of a lubricating composition for lubricating gear, wherein the lubricating composition comprises: at least a base oil; and at least a Molybdenum or Tungsten chalcogenide nanoobject having an object size ranging from 0.1 to 500 nm and from 1 to 99% by weight of molecules of formula (I) with respect to the total weight of the nanoobject

Disclosed is a lubricant composition including: at least one base oil; at least one olefin copolymer; at least one detergent; and at least one hydrogenated and linear styrene/butadiene copolymer. Also disclosed is the use of this composition for reducing the fuel consumption of an engine and for improving the cleanliness of a 4-stroke or 2-stroke, preferably 4-stroke marine engine, or of a stationary engine.

A crankcase lubricating oil composition for the crankcase of a spark-ignited or compression-ignited internal combustion engine, comprising a magnesium-containing detergent, in an amount sufficient to provide from 200-4000 ppm magnesium to the lubricating oil composition, in combination with an oil-soluble or oil-dispersible molybdenum compound in an amount sufficient to provide from 600-1500 ppm molybdenum atoms to the lubricating oil composition, and with an oil-soluble or oil-dispersible boron-containing compound in an amount sufficient to provide from 200-600 ppm boron atoms to the lubricating oil composition to improve the friction and fuel economy performance.

A lubricating composition includes an oil of lubricating viscosity and an N-substituted hydroxyaromatic succinimide or a salt thereof.

The invention relates to aqueous composition comprising water-soluble glycerin-based polyalkylene glycols as synthetic base oils as well as the use of the composition and the glycerin-based polyalkylene glycols as or in metalworking fluids, wherein the glycerin was consecutively alkoxylated in the following order: first with propylene oxide, followed by ethylene oxide and finally with propylene oxide.

The instant disclosure provides a process for preparing a lubricant or fuel additive mixture where an oil of lubricating viscosity or fuel are blended with additives that are mixed via an acoustic mixer. The additives and oil of lubricating viscosity or fuel can mixed together or any component of the lubricant or fuel additive mixture can be mixed separately prior to mixing to form the final lubricant. The process provides for continuous mixing to form lubricant and/or fuel additive mixture final products.
