Waste frying oil is a harmful liquid to human body and environment. However, it can be utilized as fuel. Transesterification of waste frying oil with methanol is presence of potassium hydroxide as catalyst produces fatty acid methyl ester (FAME) known as biodiesel as main product with glycerol as byproduct. Previously, several researches have been carried out concerning about utilization of both substances as renewable liquid fuel. In this research, three materials biodiesel, glycerol, and methanol which involved in transesterification process are combined in order to determine another renewable liquid fuel. Combination with composition 1:1:1 to 1:1:4 (v/v) is burned in an external combustion engine. Viscosity of glycerol is the main problem to form fuel for the engine. The result shows that the higher percentage of the methanol, the easier is the combustion. Composition by volume 1:1:4 of biodiesel, glycerol, and methanol respectively is the best mixture of liquid fuel for boiler burner.
