Abstract: A system, for use in accounting for an effect of a long-trip cycle on remaining life of engine oil, being used in a vehicle, using a long-trip rebate value. The system includes a computer processor and a non-transitory computer-readable medium that is in operative communication with the processor and has instructions that, when executed by the processor, cause the processor to perform various operations. The operations include determining a long-trip time indicating an amount of time that the vehicle was operated recently in the long-trip cycle. The operations further include determining the long-trip rebate according to a rebate function using the determined long-trip time.

Abstract: Systems and methods for system for encouraging compliance with a recommendation related to engine oil of a vehicle. The system includes a computer-readable medium having instructions causing a processor to (A) determine that a communication regarding the engine oil life should be sent providing at least one datum of (i) information considered in generating the communication, (ii) a predicted result of following the recommendation, being a first predicted result, (iii) a predicted result of not following the recommendation, being a second predicted result, (iv) a message including a positive remark, being a first message, and (v) a message including a remark identifying an improvement that can be made, being a second message. The method can also include (B) sending the communication from the processor to a destination.

Abstract: One embodiment of the invention includes a method for testing a fluid for contamination by a mycobacterial organism. A plurality of individual standardized samples may be acquired from a plurality of predetermined sampling points and pooled into a pooled sample. The pooled sample may be analyzed using a polymerase chain reaction technique and the results compared against a pool concern level which is calculated from an individual concern level that governs each individual standardized sample.
