Ascending number of vehicles around the globe leads to higher rates of growth in demand for oil. In the context of Malaysia, this growth expected to be more rapid in years to come which may contribute to depletion of oil resources. In order to conserve
and sustain oil resources, there is a need to extend the use of ATF in automotive vehicles. The aim of this study is to investigate the quality and effectiveness of the extended oil in performing its intended purposes of providing sufficient protection to the AT system and most importantly assurance of minimal occurrence of wear within the system. Oil analysis approach has been deployed in order to attain understanding of wear behavior in automatic transmission (AT) system analyzed at two different mission profiles. This approach may be common in engine oil analysis as suggested in literatures. Nevertheless, the deployment of the oil analysis technique to investigate wear behavior in transmission system has not been fully explored. This becomes the impetus of the study. Based on the analysis done, it was noted that ATF degradation was insignificant even though the ATF samples were used beyond the recommended period and tested at a continuous high speed value of 3,000 rpm. Besides, the depletion of vital anti-wear property, namely ZDDP was minimal and hence did not
affect the quality of the ATF. Based on the qualitative analysis, the ATF samples were found to have acceptable key additives level, insignificant contaminants and normal wear mode. In general, this study suggests that the use of ATF might be extended beyond the existing recommended period. However, future studies need to be
conducted to fiirther understand the potential of using ATF beyond the recommended period
