Oil analysis (OA) is the laboratory analysis of a lubricant's properties, suspended contaminants, and wear debris. OA is performed during routine preventive maintenance to provide meaningful and accurate information on lubricant and machine condition. By tracking oil analysis sample results over the life of a particular machine, trends can be established which can help eliminate costly repairs. The study of wear in machinery is called tribology. Tribologists often perform or interpret oil analysis data.
OA can be divided into three categories:
- analysis of oil properties including those of the base oil and its additives,
- analysis of contaminants,
- analysis of wear debris from machinery,

Famous quotes containing the words oil and/or analysis:
“Courage, determination, and hard work are all very nice, but not so nice as an oil well in the back yard.”
—Mason Cooley (b. 1927)
“... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.”
—Alice Foote MacDougall (1867–1945)
