Abstract: Systems and methods are provided for authenticating working fluids. The systems and methods include exposing at least a portion of a working fluid containing a UV-reactive chemical marker to light having wavelengths in the range of about 10-400 nm, thereby causing the chemical marker to generate a signal. The signal can be detected via a sensor system and compared to a reference signal that is associated with an authentic working fluid. An output may be generated to indicate whether the working fluid is the authentic working fluid.

Abstract: Systems and methods are provided for in-situ characterization of a working fluid based on fluorescent backscattering. Instead of attempting to transmit light through the working fluid, backscattered fluorescent light generated by the working fluid and/or by a fluorescent marker in the working fluid can then be detected. Thus, fluorescence can be induced in or near a surface layer of the fluid relative to the housing containing a light source, and the resulting fluorescence can be detected by a detector located in the same housing or an adjacent housing. By avoiding the need to transmit light through the liquid, difficulties with absorption and/or scattering due to particles, soot, or other debris in the working fluid can be reduced or minimized. This can allow detection of the fluorescence to be maintained as a working fluid ages.

Abstract: A method for improving wear control and sludge control, while maintaining or improving fuel efficiency, of a lubricating oil in an engine or other mechanical component lubricated with the lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one lubricating oil additive, as a minor component. The at least one lubricating oil additive includes a zirconium-containing compound. The zirconium-containing compound is present in an amount from about 0.1 to about 1200 parts per million (ppm). The zirconium-containing compound is soluble in the lubricating oil base stock. The lubricating oil is useful as a passenger vehicle engine oil (PVEO), a commercial vehicle engine oil (CVEO), and other lubricating oils (hydraulic, gear, transmission, etc.).
