The invention provides fuel mixtures containing biodiesel oil, glycerol, glycerol soluble compounds, surfactants and additives. The fuel mixtures are uniform, remain suspended in solution, and are resistant to phase separation. Upon combustion, the mixtures generate reduced CO, CO2, SOx, NOx and particulate matter emissions compared to petroleum fuels and offer improved engine performance over petroleum and water mixtures.
