The ever-increasing price of petroleum products coupled with global climate change, environmental pollution and limited availability of fossil fuel called the need for renewable fuels. Biofuel from biomass, spent oil is such a renewable fuel with the added advantage of also cleaning the environment. Therefore, this research reports the Biofuel potential of the seed oil of Zizyphus abyssinia, Zizyphus jujube, and Olea europeae. The seeds extracted with petroleum ether gave low yield and the physical, chemical and fuel properties of the oil were determined. Meanwhile, the extracted oils were golden yellow in colour. The flash point, pour point, viscosity, refractive index, and specific gravity were determined and the Flash point was 118oC, 141oC and 218oC respectively. The pour point was 60C, 8oC and 9oCrespectively.Whereas, the carbon residue was (0.85 and 2.00%); and percent Sulphur was (0.026 and 0.066%). Then the ash content was (0.72, 0.75 and .0.77%). The fuel properties were within the limits for biofuel. Other parameters determined included viscosity (46.31, 41.00 and 40.04), refractive index (1.453, 1.450 and 1.471), specific gravity (0.993, 0.893 and 0.787) and distillation profile. From the result, the oils have the potential for biofuel production either as the raw oil or chemically modified to the methyl or ethyl ester.
