Globally, biodiesel is mainly manufactured from animal and vegetable oils in the form of fatty acid methyl esters (FAMEs). It has been reported that the quality of biodiesel is strongly influenced by the feedstock. Therefore, in this paper, we have derived the quality characteristics of domestic biodiesel used as biofuel in automotive diesel through the analysis of 10 years of quality monitoring data. Domestic biodiesel is produced with adequate quality, satisfying both Korea and the EU in terms of fuel quality standards. Furthermore, since the implementation of the Renewable Fuel Standard (RFS) in 2015, it has been found that the mandatory blend ratio of automotive diesel is lower in winter (average 2.3 vol%) compared to summer (average 3.4 vol%) due to the lower fuel quality in winter.
