Petroleum derived products have an important role in different sectors of Bangladesh and so their quality should be measured and controlled carefully to get higher performance of engine. Physico-chemical characteristics of High Speed Diesel (HSD) collected from Titas gas field of Bangladesh have been determined using standard procedures set by American Society of Testing and Materials (ASTM) and Institute of Petroleum (IP). These results have been compared with the standards specifications of BSTI, ERL, European, Indian and Pakistan to assess the quality. Sometimes additives and essential chemicals are added to the final product to enrich its quality or reduce its utilization abatements. The quality of Titas HSD is almost identical to the BSTI and ERL specifications but the quality of these products is low in some cases as compared to the European, Indian and Pakistan standard specifications. It is proposed that amendment of some parameters of BSTI and ERL should be carried out to sustain the fuel quality. To enrich the diesel fuel quality cetane number, flash point, kinematic viscosity and water content values set by BSTI and ERL should be modified according to European, IS and PSI specifications. The characteristics of produced diesel are close to BSTI and ERL standard except cetane number (42.2), Kinematic viscosity (1.68 cSt) and flash point (37.78°C).
