Abstract:
Customer expectations of longer lubricant durability continue to increase with new technologies such as EV and hybrid vehicles. Oxidation of base oil is a primary reason for lubricant failure. Three lubrication base oils (synthetic, group III, and group I) were oxidized via rotating pressure vessel oxidation technique (RPVOT) and then analyzed by a flow-modulated two-dimensional gas chromatograph coupled to a time-of-flight mass spectrometer (GCxGC- TOFMS). This preliminary work demonstrates identification of low-level oxidation products (acids, ketones and aldehydes), and links the timing of the oxidation product formation over the course of RPVOT testing to base oil type.
