Abstract: A method for improving corrosion resistance, while maintaining or improving fuel efficiency, in an engine or other mechanical component 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 at least one friction modifier having an elemental composition comprising one or more of nitrogen (N), oxygen (O), and phosphorus (P), as a minor component. The formulated oil has a corrosion factor, based on the elemental composition of the at least one friction modifier, of less than 500, as determined by the formula: 12900(N wt %)+3967(O wt %)−8524(P wt %)−250=corrosion factor. The lubricating oils are useful as passenger vehicle engine oils (PVEO) and commercial vehicle engine oils (CVEO).

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: Provided is a lubricating oil composition and methods for controlling one or more of foam tendency and foam stability in such composition using as the oil a mixture of at least two base stocks. The at least two base stocks have a surface tension difference between them such that, when the surface tension difference is greater than 1.0 dynes/cm, then one or more of foam tendency and foam stability are enhanced as compared to foam tendency and foam stability achieved using the base stocks separately and not in the mixture. When the surface tension difference between them is less than 1.0 dynes/cm, then one or more of foam tendency and foam stability are reduced or equivalent as compared to foam tendency and foam stability achieved using the base stocks separately and not in the mixture. Two low-foaming base stocks can produce a significant high foam response that reduces or eliminates the need for pro-foaming additives.

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: Provided is a low sulfated ash engine oil lubricant composition containing organic friction modifiers with improved fuel economy and corrosion resistance. The lubricant composition includes one or more metal free corrosion inhibitors having an organic acid group and/or one or more organo metallic naphthalene molecules having a ASTM D2896 total base number less than 3 mg KOH/g. The resulting lubricant composition improves ASTM D6557 corrosion protection for low sulfated ash engine oils containing organic friction modifiers, while maintaining exceptional fuel economy performance.
