Abstract:
Analysis of automobile engine oil samples taken at 20 hour intervals of a 100 hour dynamometer test with direct analysis in real time (DART) time of flight mass spectrometry has been used to identify and monitor the diphenylamine antioxidants in the oil. This monitoring of antioxidant content is a preemptive way to determine when an engine oil will begin to rapidly oxidize due to lack of antioxidant protection. The speed of this technique may be useful in monitoring an oil's ability to mitigate oxidation during engine dynamometer testing.
