This study aims to investigate the use of octane booster on pertalite (gasoline with an octane number of 90), analyze the effect of mixed storage time, and compare it with Pertamax (gasoline with an octane number of 92). The selected storage times are 0 weeks, two weeks, and four weeks. This research was started by adding an octane booster to pertalite, and a portion of the pertalite and octane booster mixture was stored for two weeks and four weeks. Samples were characterized by octane number, density, viscosity, torque, and engine power. The results showed that the performance of boosted pertalite increased, then decreased with increasing fuel storage time. The original Pertalite has an octane number of 89.9 and strengthened pertalite at 90.8. Then, after two weeks, it dropped to 90.5, then 90.4 in the fourth week. Pertalite viscosity was 0.630 cP, pertalite boost 0.589 cP, 0.593 cP in the second week, and 0.612 cP in the fourth week. Pure Pertalite 7.54 HP, boosted pertalite increased by 7.80 HP, in the second week 7.69 HP and 7.66 HP in the fourth week. © 2023 Novel Carbon Resource Sciences. All rights reserved.
