Abstract : In this paper, GC-MS analysis of gasoline traces on engine oil, brake oil, hydraulic oil, and power steering oil has been carried out using Alstoniascholaris wooden slips as the substrate. The GC-MS analysis was conducted with electron impact ionization at 70 eV and a flow rate of 1.5 ml/min. Only indane with 1,2,3,5- tetramethylbenzene and only dodecane were identified,respectively, as interferences with gasoline target compounds related to hydraulic oiland engine oil. After burning, indane and 1,2,3,5-tetramethylbenzene were disappeared.

Keywords : Gas Chromatography-Mass Spectrometry, Auto Mobile fluids, Substrate.
