This informative video explains how used oil analysis limits and alarms are determined and their significance in proactive and predictive maintenance. Through various examples like Jenbarker gas engines, the speaker discusses the process a lab goes through to define limits and determine their appropriate applications. The video provides insight into contamination control, wear information, goal-based limits, age-based limits, and the role of rate of change limits in indicating machine condition. It also explains how to interpret a wear particle trend and use statistical reasoning to set up limits. Finally, it explains why obtaining like-for-like data from comparable machines is crucial and how vast databases in oil analysis labs provide a more accurate setting of these limits than an individual or small group can.
