Abstract: Methods are provided for in-situ detection of varnish and/or deposit precursors in a lubricant in a lubricating environment. An electrostatic accumulator can be used within a lubricating environment to enhance accumulation of varnish and/or deposit precursors on portions of the electrostatic accumulator. The deposits accumulated on the electrostatic accumulator can then be characterized in-situ. The potential difference across portions of the electrostatic accumulator can cause an enhanced rate of deposit accumulation on the electrostatic accumulator, which can facilitate characterization of the tendency of a lubricant to accumulate deposits in the lubricating environment.

Abstract: A system for in-situ identification of a working fluid disposed in at least one piece of equipment, the system including: a working fluid reservoir that contains the working fluid; an in-situ sensor disposed in the working fluid reservoir such that it detects properties of the working fluid or computes properties from the generated spectra of the working fluid; a transmitter that transmits the detected spectra of the working fluid and equipment identification information; and a cloud computing system that receives the detected spectra and the equipment identification information transmitted from the transmitter, wherein the cloud computing system compares the spectra and equipment identification information against a reference database to determine whether or not the spectra of the working fluid substantially matches the stored reference spectra associated with the expected or specified fluid for the equipment.

Abstract: A method for improving friction reduction and fuel efficiency, while maintaining or improving wear protection, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition comprising a lubricating oil base stock as a major component; and a detergent mixture comprising a first detergent having a TBN of less than about 100, and at least one other detergent different from said first detergent, as a minor component. The composition contains greater than about 4 weight percent of the first detergent, based on the total weight of the formulated oil. Friction reduction and fuel efficiency are improved and wear protection is maintained or improved as compared to friction reduction, fuel efficiency and wear protection achieved using a lubricating engine oil containing a detergent mixture having other than the first detergent having a TBN of less than about 100.
