Abstract :The effects of dill oil extract as an antioxidant on the crystallization properties of colza biodiesel were investigated. 3000 ppm dill oil insert ignore into journalissuearticles values(Anethum graveolens); was blended with colza biodiesel-diesel mixtures at certain rates. The chemical antioxidant butylated hydroxytoluene insert ignore into journalissuearticles values(BHT); was used to compare the effects. For this reason, the samples were prepared and called D100, B20D80, B20D80D, and B20D80BHT. The crystallization temperatures insert ignore into journalissuearticles values(Tcr); of the samples were determined by using a Differential Scanning Calorimetry insert ignore into journalissuearticles values(DSC); technique. The values of samples with antioxidants were decreased compared to the non-antioxidant biodiesel sample insert ignore into journalissuearticles values(B100);. The order of antioxidant power was D100for D100, B20D80, B20D80BHT and B20D80D were −11.3 7 °C, −13.42 °C, -14.94 °C, and −15.65 °C, respectively. The addition of dill oil extract as a natural antioxidant had a positive effect on biodiesel oxidative stability for 3000 ppm concentration. Natural dill oil showed a similar  efficiency with BHT that the synthetic chemical antioxidant. The dill oil can be used as an antioxidant after the complete standard fuel tests.
