ABSTRACT
Due to increasing biodiesel production from vegetable oils, there is need for more research on how biodiesel stability and quality can be improved. Therefore, this study has compared the oxidative stability of biodiesel produced from watermelon seed oil with and without the addition of a natural antioxidant - Mitrcarpus scaber. The work examined the biodiesel stability properties such as kinematic viscosity, peroxide and acid values over time. It was found that for a period of 16 days, the biodiesel sample containing the antioxidant showed more stability as seen in the lower peroxide, acid and kinematic viscosity values compared to the biodiesel sample without antioxidant. This implies that under storage conditions, biodiesel stability as well as quality can be ensured when the biodiesel is combined with natural antioxidants such as Mitracarpus scaber.
