Ricinus communis crude oil was converted to Biodiesel using a two-step trans esterification reaction. The produced biodiesel was identified using GC-MS techniques, the results show that the total ester content in the biodiesel was 98.86% of the total components of produced Ricinus communis biodiesel. The physical and chemical properties of Ricinus communis biodiesel were compared with the ASTM D 7467 requirements. B20 blend of biodiesel with Diesel were all within the level of ASTM D 7467. Biodiesel-Diesel-Ethanol blends were investigated and compared also with standard method ASTM D 7467 and all the results were found with the standard requirements. The flashpoint of pure biodiesel was 143 C, reduced to 77.5 C in the B20 blend and reduced to 16 C in D60 B20 E20.
