Lube oil analysis is an analysis technique that determines the condition of lubricating oils, which is used in mechanical and electrical equipment. It is not a tool for determining the operating condition of machinery or detecting potential failure modes. This analysis should be limited to proactive program to conserve and extend the useful life of lubricants. Some form of lubricating oil analysis may provide an accurate quantitative breakdown of individual chemical elements such as oil additive and contaminants that is contained in the oil. The primary applications for lubricating oil analysis are quality control, reduction of lubricating oil inventories and determination of the most cost-effective interval for oil change. Lubricating, hydraulic and dielectric oils can be periodically analyzed using these techniques to determine their condition. The results of this analysis can be used to determine if the oil meets the lubricating requirements of the machine or application. Based on the results of the analysis, lubricants can be changed or upgraded to meet the specific operating requirements.
