Oil Analysis


Oil analysis provides a detailed view of what is happening within machine components during operation. An oil sample from a piece of equipment can reveal many things about the condition of both the oil and the machine – much like a blood sample taken from a person.


Effective oil analysis programs identify wear, contamination and changes in a lubricant’s physical properties that can adversely affect machine health and reliability. Using quality test results and easy-to-understand maintenance recommendations, equipment managers and reliability personnel can effectively assess equipment condition, plan maintenance schedules, prevent breakdowns and maximize up-time at a minimal cost.

Wear, Contaminant & Additive Metals

Spectrochemical Analysis, or Elemental Analysis, is the cornerstone of an effective oil analysis program. It detects 21 metallic elements that can represent wear metals, wear corrosion, dirt contamination and oil and coolant additives in the lubricant.

Physical Properties

Although oil analysis encompasses a wide variety of tests and methodologies, routine testing typically includes Viscosity, Acid and Base Numbers, Water Content, Soot and Fuel Dilution to determine the effectiveness of anti-wear, dispersant and detergent additive packages. More advanced testing through Particle Count Analysis determines fluid cleanliness. Analytical Ferrography identifies types of wear occurring and the Rotating Pressure Vessel Oxidation Test (RPVOT) predicts the fluid’s remaining useful life.
