Energy production from waste in the world will be an indispensable factor for the future of countries. Countries that can produce their own energy in the world will be superior to other countries. In this study, waste sunflower oil was converted to methyl ester by transesterification method and biodiesel was produced. A Ternary mixture was made from biodiesel, ethanol and euro diesel fuel obtained from waste sunflower oil and test fuels were produced in the forms of D90B5E5, D80B10E10, D70B15E15 and D60B20E20. The kinematic viscosities of the test fuels at 40 0C, density, water contents, pH values, color specifications, calorific values, cloud points, yield points, freezing, copper strip corrosion tests, CFPP tests and cetane index tests were carried out and fuel properties were determined. As a result of the tests, it was found out that the most suitable engine fuel mixture was D90B5E5. It can be used for internal combustion engines by adding ethanol to the Biodiesel – Euro diesel fuel mixture and in this way, an environmentally friendly fuel mixture is obtained and energy conversion is achieved from waste.
