Potentials of Citrus sinensis seed oil were evaluated for its biodiesel and lubricating properties. The oil of C. sinensis seed was extracted using n-hexane and then transesterified using various methanol: oil ratios. The physicochemical properties of the oil and the resultant biodiesel, such as viscosity, acid value, iodine value, free fatty acid value, pour point, cloud point, smoke point, specific gravity and surface tension, were determined. The raw oil exhibited a low oxidative stability, while the biodiesel ratio with the highest methanol content had a biodiesel potential that could compete favourably with that of fossil diesel. The test for the burning efficiency of the respective biodiesel ratios indicated that the ratio with the lowest alcohol content had the best burning efficiency. This was evident from its relatively low flash point. The study concluded that the non-edible oil obtained from the seeds of C. sinensis could serve as a highly reliable substitute for the production of very good quality biodiesel fuels.
