Abstract: A method for improving fuel efficiency testing precision in on-road vehicles. The method comprises: installing one or more dataloggers in one or more vehicles, each datalogger configured to receive fuel consumption data broadcast by an on-road vehicle's engine control unit (ECU); transmitting the fuel consumption data from the one or more dataloggers in the one or more on-road vehicles to a processor; and analyzing, using the processor, the fuel consumption data from the one or more dataloggers in the one or more on-road vehicles to determine fuel efficiency of the one or more on-road vehicles. The fuel consumption data comprises fuel rate data from the ECU which is transmitted through the one or more dataloggers, engine speed and other operating parameters from the ECU that are transmitted through the one or more dataloggers, torque sensor data which is transmitted through the one or more dataloggers, and traditional fuel log data.

Abstract: A method for improving oxidative stability of a lubricating oil in a diesel engine 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 aminic antioxidant, at least one phenolic antioxidant, and at least one Group V base stock as minor components. The at least one aminic antioxidant is present in an amount from 0.1 to 2.5 wt. %, the at least one phenolic antioxidant is present in an amount from 0.5 to 5 wt. %, and the at least one Group V base stock is present in amount from 1 to 20 wt. %. Oxidative stability is improved in a diesel engine lubricated with the lubricating oil, as compared to oxidative stability achieved in a diesel engine lubricated with a lubricating oil containing a minor component other than specified antioxidants and Group V base stock.

Abstract: A working fluid monitoring system for monitoring a working fluid of a working fluid system of a piece of equipment. The working fluid monitoring system can include a housing member having a working fluid passage for receiving the working fluid therein and a sensor in operable communication with the working fluid within the working fluid passage of the housing member configured to monitor in situ the working fluid and output a sensor signal. The working fluid monitoring system can be quickly and conveniently retrofitted to existing machinery for in situ monitoring, detecting, testing, and/or validating of a working fluid, such as oil, hydraulic fluid, and the like.

Abstract: Provided are lubricating engine oils including a lubricating oil base stock as a major component having a base oil viscosity at 100 deg. C. ranging from 4.5 to 7.5 cSt, and a carboxylic functionalized polymer dispersant with aromatic amine functionality, as a minor component, wherein the lubricating engine oils have a cold crank simulator viscosity at ?30 deg. C. of less than 8500 mPa·s. The lubricating engine oils may provide improved engine wear protection at equivalent fuel efficiency or improved fuel efficiency at equivalent engine wear protection compared to a lubricating engine oil containing a dispersant as a minor component other than the carboxylic functionalized polymer with aromatic amine functionality. Methods of making the lubricating engine oil are also provided. The lubricating engine oils are useful in internal combustion engines including direct injection, gasoline and diesel engines.
