The aim of this study was to compare oxidation stability, emissions during engine tests and fuel properties of biodiesels. The biodiesels were produced from different raw materials using the transesterification process. The raw materials used were: salmon oil, fox fat, rainbow trout oil, rapeseed oil and linseed oil. The engine tests showed differences in emissions with different biodiesels. The fatty acid profiles were measured and their effect on oxidation stability and other fuel properties were noticeable. The effect of synthetic antioxidant was also measured for different biodiesels. The oxidation stability increase was related to the raw material used to produce the fuel. The oxidation stability of biodiesel blends was measured. The oxidation stability of the blended fuel increased when biodiesel with a higher oxidation stability level was introduced. These measurements indicate that oxidation stability can be enhanced with antioxidants and by blending diesel fuel or other biodiesels together.
