| Abstract: | Two methods for monitoring the degradation of engine oil in service through TAN change and FTIR spectroscopy are analyzed and their characteristics are investigated by contrasting the test data obtained from different methods in the field test. It is pointed out that the TAN change limit value of high grade engine oil should be different from that of medium and low grade engine oils. The study provides a reference for selecting the proper test methods and standards to monitor engine oil in service. |
