This paper focuses on evaluating the potential of sawdust-derived antioxidants in oxidative stability of the lubricant oil samples monitored through gas chromatography-mass spectrometry (GC-MS). The plain and antioxidants-spiked oil samples were subjected to artificial aging at 100 degrees C for 6 h in a flow of air (10 L h(-1)). The results indicate that the antioxidants under study imparted thermo-oxidative stabilities to the oil compared to the plain sample and exhibited good antioxidants potential at 100 degrees C.
