Plant oil extracted from Kanyu almonds offers the potential to be an alternative to fossil fuel resources. This study aims to characterization the physic-chemical properties of kanyu almond oil, as safe indicators of the use of this biofuel for energy generators. Samples of the oils as examined were density, kinematic viscosity, acid value, and oxidation stability. The experimental results showed that the oils had different sensitivities to the properties and that a clear deterioration of the kinematic viscosity and oxidation stability. These results were not in a condition to be used directly, such as fuels in diesel engines. Also, oil cannot be used immediately for feeding because it contains a high acid value. However, with the refining process, its kinematic viscosity and acid value can be improved, and can thus use as biofuel and for other purposes.
