Oil Condition Monitoring
Modern maintenance is moving away from fixed service schedules and towards condition-based maintenance, where decisions are based on measured equipment health rather than operating hours alone.
Engine oil provides a wealth of information about the condition of both the lubricant and the engine itself. By monitoring changes in oxidation, viscosity, acidity, contamination and wear, engineers can identify developing problems, avoid unnecessary oil changes and reduce the risk of unexpected failures.
This section explains the principles behind oil condition monitoring, laboratory oil analysis and real-time monitoring technologies. You'll learn how lubricant condition is assessed, why trend analysis is more valuable than a single measurement, and how modern monitoring systems help maintenance teams make informed decisions that improve reliability while reducing operating costs.
Whether you manage a standby generator, a prime power installation, a hydraulic system or an industrial diesel engine, understanding oil condition is one of the most effective ways to optimise maintenance and maximise equipment life.
What Can Oil Analysis Tell You?
Learn what laboratory oil analysis reveals about lubricant condition, contamination, wear and machine health, and how it supports predictive maintenance.
What Does TBN Mean? A Guide to Total Base Number in Engine Oil
Learn what Total Base Number (TBN) means in engine oil analysis, why it decreases as lubricants age and how it helps engineers determine remaining oil life.
What Does TAN Mean? A Guide to Total Acid Number in Engine Oil
Learn what Total Acid Number (TAN) means in engine oil analysis, why it increases as lubricants age and how it differs from real-time oil condition monitoring.
Can Sensors Predict Engine Failure?
Can sensors predict engine failure before it happens? Discover how oil condition monitoring, vibration analysis and condition-based maintenance identify early warning signs and help prevent costly breakdowns.
Why Scheduled Oil Changes Waste Money
Discover why changing engine oil at fixed service intervals can increase maintenance costs and how condition-based maintenance helps determine the right time to replace lubricant based on its actual condition.
