Claim Text:
1. A system, comprising: a plurality of sensor devices comprising a first sensor device and a second sensor device sensing distinct properties of oil used in a vehicle and generating first sensor-device data and second sensor-device data respectively; and a processing device configured to receive the first sensor-device data from the first sensor device and determine, regarding a first oil property of the distinct properties for the oil used in the vehicle, a first set of oil-property characteristics comprising: wherein the processing device is further configured to receive the second sensor-device data from the second sensor device and determine, regarding a second oil property of the distinct properties for the oil used in the vehicle, a second set of oil-property characteristics, comprising: wherein the processing device is further configured to generate, using at least the first set of oil-property characteristics and the second set of oil-property characteristics, a system output comprising a single index value indicating a state of deterioration of the oil used by the vehicle, and the generating including performing at least one of a first function and a second function for determining an oil-deterioration index (ODI) as the single index value, the first and second functions being, respectively, as follows:
