Lubricants are essential for maintaining the efficiency and longevity of machinery. However, over time, they can degrade or become contaminated, leading to equipment failures, increased downtime, and costly repairs. Regular lubricant health checks can help identify potential issues early, ensuring optimal performance. Here’s how to perform a lubricant health check and recognize signs of degradation and contamination.

Visual Inspection

A quick visual inspection can reveal a lot about the condition of your lubricant. Check for:

  • Colour Changes: Fresh lubricants have a clear or amber hue. Darkened oil may indicate oxidation or contamination.
  • Sediment or Particles: Dirt, metal shavings, or sludge suggest wear, contamination, or degradation.
  • Foaming or Bubbles: Excessive foam can indicate air entrainment, often caused by improper application or contamination.

Odor Check

Unusual smells can signal lubricant degradation. A burnt or acrid odor may suggest excessive heat exposure or oxidation, while a rancid smell could indicate microbial contamination.

Water Contamination Test

Water contamination can lead to rust, reduced lubrication effectiveness, and component failure. To check for water:

  • Blotter Spot Test: Place a drop of oil on blotter paper. If it spreads unevenly or has a water ring, moisture is present.
  • Crackle Test: Heat a small sample of lubricant on a hot plate. If it crackles, water contamination is likely.

Viscosity Check

Lubricants must maintain their original viscosity to function correctly. If oil appears too thin or too thick, it may have deteriorated or become contaminated. A simple viscosity test involves comparing used oil to a fresh sample by observing how it flows.
