This study compares the quality of Pertalite fuel at Gas Stations (SPBU) with Pertamina Mini (Pertamini). The aim of the research is to compare the quality of pertaline sold in different places. The parameters used in this research were specific gravity ASTM D-1298 which showed specific gravity 60/60 "F of 0.718 for Gas Station A, 0.719 for Gas Station B, 0.720 for Gas Station C 0.720 at Pertamini A, 0.731 at Pertamini B, and 0.730 at Pertamini C. Then, distillation ASTM D-86 on temperature 90% marked the values of 210 °C, 210°C. 178 °C, and 183 C. Reid vapour pressure ASTM D-323 results were 7.1 Psig. 7.6 Psin. 65 Psig. 7.1 Psig. 3.5 Psig, and 2.9 Psig. Doctor test IP-30 showed the results negative, negative, negative, slightly positive, slightly positive, negative." Copper strip test ASTM D-130 showed the results of 1b, 3b, 2a, 2a, 3h, and 2h. The last test, the oct...
