Expert Oil Diagnostic Services
Introduction
Lubricant oil plays a critical role in the performance and longevity of industrial machinery. Whether used in engines, gearboxes, turbines, or hydraulic systems, the condition of the
lubricant directly affects equipment reliability. Oil sampling is the first and most crucial step
in lubricant analysis, serving as the foundation for accurate diagnostics and maintenance
decisions.
Why Oil Sampling Important
Early Detection of Problem
Sampling allows for the identification of abnormal wear and tear, contaminants, and degradation of the oil.
Early detection helps prevent costly failures and unplanned downtime.
Trend Condition Monitoring
Regular sampling builds a historical profile of lubricant and machine condition.
Trends in viscosity, oxidation, or particle count can indicate developing issues.
Quality Assurance
Ensures that new or in-service lubricants meet required specifications.
Verifies that oil is not contaminated during storage or handling.
Compliance and Warranty Protection
Many equipment manufacturers (OEMs) require regular oil analysis as condition of
their warranty. Proper sampling supports warranty claims and audit trails.
Common Sampling Errors
Using dirty or non-standard containers.
Sampling from non-representative locations (e.g., stagnant zones)
Taking samples when equipment is off or cold.
Delayed analysis leading to sample degradation.
Inconsistent procedures across technicians.
These errors can lead to misleading results and poor maintenance decisions.
Best Practices for Oil Sampling
Sample while equipment is running or shortly after shutdown.
Use dedicated sampling ports or valves. Always take samples from the same location to ensure consistency in the data.
Ensure clean, sealed containers are used.
Label samples clearly with date, equipment ID, oil type, operating hours.
Send samples to the lab promptly and store them in a cool, dry place.
