One of the methods to improve the combustion behavior in internal combustion engine is by introducing additive to the base fuel. However, some additive resulted in higher Brake Specific Fuel Consumption (BSFC) and emission of CO and NOx. The objective of this study is to examine the effects of fuel additives quantity to the fuel economy and engine emission. The tests were carried out at different engine speeds (1500rpm-3000rpm) and different engine loads (40Nm - 100Nm) using a four stroke gasoline engine. The additive was blended with gasoline (RON95) in composition of 5, 10 and 15 milliliter per liter accordingly. BSFC was measured using Pro V2 software and exhaust emission was measured using MRU AIR gas analyzer. Results showed that gasoline blended with 5ml fuel additive lead to a significant improvement on (BSFC) and higher carbon dioxide (CO2) in its emission. Base fuel blended with 10ml/l and 15ml/l additive showed increasing in BSFC.
