Pure biodiesel should only be used in vehicles that have been approved for biodiesel by the manufacturer. The reason: The chemical properties of the biofuel which act partially as solvents and can damage plastic and rubber components in the fuel system. The special polyamide 12 compounds from Evonik for fuel lines and return lines in the vicinity of the engine have demonstrated good aging resistance in all tests so far when used with biodiesel blends based on rapeseed methyl ester (RME).
