The invention is directed to a fuel composition for diesel engines. The fuel composition comprises 0.1-99% by weight of a component or a mixture of components produced from biological raw material originating from plants and/or animals and/or fish. The fuel composition comprises 0-20% of components containing oxygen. Both components are mixed with diesel components based on crude oil and/or fractions from Fischer-Tropsch process.
