Abstract
Systems and apparatuses relate to a system comprising a controller comprising at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising: determining a concentration of a plurality of wear metal particles in a lubricant for an engine system; determining a confidence parameter regarding the concentration determination; determining a filtered concentration of the plurality of wear metal particles using a baseline concentration of the plurality of wear metal particles; setting a diagnostic threshold for the plurality of wear metal particles based on the confidence parameter; and, responsive to determining that the diagnostic threshold is exceeded, providing a notification.
