A fuel blend comprising tall oil and mineral and/or vegetable oil, and a process for making such a fuel blend. The process comprises heating a mixture of from 10 to 90 per cent crude tall oil with the balance being mineral and/or vegetable oil to a temperature ranging from 35° C to about 100° C for a period of time sufficient to agglomerate the lignin-like dispersed substances in the mixture. The agglomerated lignin-like substances are then separated from the mixture. The fuel blend of the present invention has a significantly reduced total volume of remaining solids positively, influencing the life of the fuel filters when used in internal combustion engines.
