The Effect of Additive on Pertalite to Increase Motorcycle Fuel Efficiency
International Journal of Emerging Trends in Engineering Research, 2020 Motorcycle in Indonesia use several types of Pertamina-produced fuel, such as premium (RON 88), Pertalite (RON 90), and Pertamax (RON 92). However, the price of gasoline-based fuels continues to increase there must be innovations to save fuel use. This study measures the level of efficiency between Pertalite mixed with additives with a motorcycle ...
