Abstract

The use of fossil fuels is still dominant for internal combustion engines, especially for gasoline motors. The most commonly used fuels are premium, pertalite, Pertamax and Pertamax turbo. What distinguishes this type of fuel is the octane value contained therein and each different octane content will affect the selling price of the fuel. To use fuel efficiently with good octane values, it is necessary to mix this fuel.
By using a statistical method for mixing these fuels, a percentage of each fuel is determined, which is 25 percent to 75 percent for each fuel. Then from that percentage the octane value of each mixture is measured. Then each composition was tested on a 4 stroke gasoline motor, and the results evaluated were Power, Torque, Sfc and exhaust emissions.
The results of this study are, at a mixture of 70 percent Premium and Pertamax Turbo 30 percent produces an optimal octane value, the price is very cheap, the power can be optimal and the emissions released are very environmentally friendly.
