      abstract = {This study investigates the physicochemical properties of castor seed oil and palm kernel oil to evaluate their suitability as feedstock for biodiesel production. The oils were extracted through mechanical pressing and characterized using ASTM D6751 standard methods. Key parameters such as acid value, iodine value, saponification value, peroxide value, viscosity, density, and heating value were analysed. Castor oil exhibited higher saponification and iodine values, indicating superior lubricity and reactivity, while palm kernel oil showed lower acid and peroxide values, signifying better oxidative stability and storage performance. Both oils conformed to or closely aligned with ASTM biodiesel standards. Comparative analysis with other commonly studied feedstock reaffirmed their viability, especially when blended. An 80:20 castor-to-palm kernel ratio was found to provide an optimal balance of fuel quality and stability. These findings underscore the potential of using non-edible, locally sourced oils to produce sustainable biodiesel in Nigeria and similar resource-abundant regions of Sub-Saharan Africa.},
