The disclosure presents an apparatus and method for measuring viscosity of a lubricating oil. The apparatus has a piezo-resistive cantilever sensor for sensing a first oil viscosity parameter. The sensor has a cantilever having a pressure receiving portion for receiving pressure exerted by the lubricating oil as the lubricating oil comes into contact with the pressure receiving portion. The cantilever also has first and second resistive portions in electrical communication with a first lead and a second lead, respectively, which are in electrical communication with an electrical circuit amplification element, for creating an output signal indicative of a change in the resistive characteristics of the first and second resistive portions of the cantilever as the lubricating oil comes into contact with the pressure receiving portion. The output signal can be used for determining oil viscosity. A processor and memory compare the output signal value with a stored resistance value to provide information relating to the quality of the lubricating oil.

The present disclosure relates to organic molybdenum complexes prepared by reacting a Mannich base with a source of molybdenum. The complexes may be useful in lubricating oil compositions as at least one of an antioxidant, a deposit control additive, and a friction modifier. The organic molybdenum complexes may show a reduced tendency to color finished oils.

Oil-soluble molybdenum derivatives derived from hydroxyethyl-substituted Mannich bases

Polyalkyl (meth)acrylate copolymers comprising from about 12 to about 18 weight percent methyl methacrylate; from about 75 to about 85 weight percent of a C,-C,alkyl (meth)acrylate; and from about 2 to about 5 weight percent of a nitrogen-containing dispersant monomer provide excellent low temperature properties to lubricating oils.

Dispersant (meth) acrylate copolymers having excellent low temperature properties

Poly (meth) acrylate copolymers comprising from about 5 to about 60 weight percent of a C11-C15 alkyl (meth) acrylate; and from about 95 to about 40 weight percent of a C16-C30 alkyl (meth) acrylate provide excellent low temperature properties to lubricating oils.

(Meth) acrylate copolymer pour point depressants

Non-dispersant poly (meth) acrylate copolymers comprising from about 5 to about 15 weight percent butyl methacrylate; from about 70 to about 90 weight percent of a C10-C15 alkyl (meth) acrylate; and from about 5 to about 10 weight percent of a C16-C30 alkyl (meth) acrylate provide excellent low temperature properties to lubricating oils.

(Meth) acrylate copolymers having excellent low temperature properties

Fuel compositions contain a liquid, partially-sulfurized, hindered phenol antioxidant composition prepared by reacting a liquid mixture of phenols which contains at least 50 weight percent of one or more reactive hindered phenols with sulfur monochloride in proportions to provide from about 0.3 to 0.7 gram atoms of sulfur monochloride per mole of reactive, hindered phenol.

Fuel compositions containing phenolic antioxidants

A partially sulfurized, phenolic antioxidant having good copper corrosion properties is prepared by reacting a liquid mixture of phenols, which mixtures includes at least one reactive, hindered phenol, with sulfur chloride in proportions to provide from about 0.3 to 0.7 gram atoms of sulfur per mole of reactive phenol.

Phenolic antioxidant composition

Fuel compositions contain a liquid, sulfur-bridged, hindered phenol antioxidant composition prepared by reacting a mixture of hindered phenols with a sulfur chloride in the presence of a polar modifier.

Fuel compositions containing sulfur-bridged phenolic antioxidants

A liquid, sulfur-bridged, hindered phenol antioxidant composition is prepared by reacting a mixture of hindered phenols with a sulfur chloride in the presence of a polar modifier. The composition is an effective antioxidant in lubricating oils without causing excessive copper corrosion.
