Oil analysis is the laboratory analysis of a lubricant’s properties, suspended contaminants, and wear debris. OA is performed during routine predictive maintenance to provide meaningful and accurate information on lubricant and machine condition.

Analysis of oil is very critical & very important, as it will tell whether the oil has experienced excessive water contamination. The lab may also look at the acid and base numbers, if the acid number is too high or the base is too low, the oil needs to be changed.

An oil analysis can also detect a coolant leak within the engine, so this kind of monitoring through oil analysis helps to keep increase engine lifetime and get optimum working efficiency.
