WVO is thicker than diesel....

If you want WVO to spray like diesel you will need to pre-heat it (160F ish) so that it has similar viscosity. Then you will get similar results. If firing is the problem, and everything is cold, you will need to keep reducing your wvo blend. Many blenders also add kerosene.
