Biodiesel is the renewable and non-polluting alternative energy source derived from vegetable/non-vegetable oils by transesterification method. It is used either individually as fuels or for blending in ethanol or diesel. The use of oxygenated bio-fuels like biodiesel and ethanol in combination with diesel is an effective measure as diesel substitutes. The present research is aimed to study the phase stability of two mixed biodiesels with diesel and proof ethanols (200°, 195°, 190°, 185°, 180°and 175°) and their characterizations. These microemulsions were prepared as B15E2D83, B20E2D78 and B25E2D73 from each proof ethanol at room temperature. Total nine samples of stable microemulsion fuels of 200°, 195° and 190° proof ethanols were selected. These microemulsion fuels were studied for the stability at different temperatures i.e. 0, 5, 10, 15, 20, 25, 30, 35, 40 and 45°C, and their properties such as density, viscosity, flashpoint, cetane number and gross heating values were determined. The study showed that microemulsion fuels of 200°, 195° and 190° proof ethanols were found unstable at 0 and 5°C in the control chamber otherwise; stable at other selected temperatures. The fuel properties of the selected microemulsions were found in the limit of the standard specification except flashpoints.
