Oil Condition Monitoring (OCM) is the systematic process of measuring, tracking, and analyzing the physical and chemical properties of lubricants to evaluate the health of a machine. It functions like a “blood test” for machinery—by analyzing a sample of the oil, technicians can detect internal engine wear and contamination before a catastrophic mechanical failure occurs.
• Predictive Maintenance: OCM is a core pillar of predictive maintenance (maintaining equipment based on its actual condition rather than a fixed schedule).
• The Three Pillars of OCM: OCM answers three fundamental questions about a machine:
1. Oil Condition: Is the lubricant still fit for service? (Checking if additives are depleted or if the oil has degraded).
2. Contamination: Has something entered the oil that shouldn’t be there? (Checking for water, soot, fuel dilution, or dirt).
3. Machine Wear: Is the machine wearing out? (Detecting microscopic metal particles from internal components).
