  8. Summary • After 9 months indoor and outdoor storage, the oxidation stability of untreated SBO-based biodiesel decrease with increasing time, while antioxidant can improve the oxidation stability of the biodiesel. • Induction period changes differ depending on antioxidant: TBHQ can improve IP and remain constant for up to 9 months, while PY and PG decrease significant. • PY and PG are not very stable at higher temperature (Summer).
