This manual gived precise and to the point information on biodiesel. Biodiesel is chemically referred to Fatty Acid Methyl Ester (FAME). Biodiesel is produced from raw vegetable oil or animal fat and methanol. It is chemically distinct from petroleum diesel and bears quality risks, depending on feedstock (fuel ageing, cold flow), given physical properties (fuel evaporation), and accuracy of production process (contamination). Therefore, the use of biodiesel can have technical implications upon the operation of the engine/fuel system. Mercedes-Benz approves the use of B5 according to ASTM D975 (standard Ultra Low Sulphur Diesel (ULSD) with a maximum of up to 5 % biodiesel) in all Common Rail Injection (CDI) and BlueTEC diesel engines.
