To improve the situation in the biofuel usage sphere, in June, 2009 the Cabinet of Ministers of Latvia accepted modifications to the ''Regulations on petrol and diesel fuel conformity assessment'' and ''Regulations on biofuel quality standards, conformity assessment, market surveillance and the procedure of consumer information''. The modifications stated that from the 1st of October, 2009 the 95th gasoline can be distributed only with the 4.5 to 5 % mix of bio-ethanol and diesel fuel - with the 4.5 to 5 % mix of biodiesel, but these requirements are not applied to the arctic diesel fuel. The aim of the investigation is to establish the compatibility of biodiesel with arctic diesel fuel testing the blends B3, B4, B5 and B7 according to the standard LVS EN 590:2005 ''Automotive fuels - Diesel Fuel - Requirements and test methods''. The main parameters of interest in this research are the temperatures of Cold Filter Plugging Point (CFPP) and Cloud Point (CP) and their change tendencies depending on the biofuel content. Analyzing the results each 1 % of biodiesel mix changes the CFPP temperature by an average of 0.7 %. In absolute numbers the 5 % biodiesel mix lowered the CPFF temperature from -42 deg C to -40 deg C. Each 1 % of biodiesel mix changes the CP temperature by an average of 1 %. In absolute numbers the 5 % biodiesel mix lowered the CP temperature from -23 deg C to -22 deg C. Adding more biofuel up to 7 %, Cloud Point temperature was -21 deg C, so such mixture does not satisfy the requirements for the 2nd Arctic class diesel fuel.
