Biodiesel is relatively higher corrosive compared to Diesel; consequently, the concern of viability is now a foremost issue. The biodiesel is self-oxidative in the environment; thus, its characteristics might be changed as fuel. The current work investigates the behavior of numerous biodiesel corresponding to corrosion when exposed to the surface of metal coupons. A gas chromatography mass spectrometry (GC-MS) was performed on eight biodiesel and a hypothesis was proposed to corroborate the hypothesis; static immersion tests, scanning electron microscopic (SEM) and surface roughness analysis were conducted. The immersion test was conducted for 150 days at ambient temperature conditions; later on, the corrosion rate of metals was examined. Results indicate that the Bronze has a maximum corrosion rate of 0.0674 mpy with Karanja biodiesel, followed by palm biodiesel. The Karanja biodiesel has the highest susceptibility to corrosion with all metals, while the Diesel is found to be the lowest with intermediate values for Rapeseed and Castor.
