The Use of Chemiluminescence for the Ranking of Lubricants in Terms of Oxidation Stability

In this study, a chemiluminescence apparatus (CL), ATLAS CL–400, was employed to measure the oxidation induction time (OIT) of various types of lubricants. Results of OIT obtained for base oils and industrial oils were compared to that obtained from standardized methods requiring larger expenditures of sample and/or analysis time. Some exploratory tests were also run on engine oils having increased expected performance.

The technique was found to be very good for the ranking of lubricants since the relative oxidation stability of the products studied has been successfully evaluated by chemiluminescence (CL). This method was shown to be a good tool for oil formulation optimization.
