Vegetable Temperature At What Temperature Is Vegetable Oil As Viscous As Diesel Fuel.?

At what temperature is vegetable oil as viscous as diesel fuel.? - vegetable temperature

I drive Ford Tempo Diesel WVO (vegetable oil) and sometimes I have problems with it. I run the oil through a heater before they would take the fuel filter, it could still be hot when it reaches the engine. But, I wonder how hot the oil should be whether it can pass right through the nozzles, and enter the engine. Now the heater thermostat is set at 150. Suggestions would be helpful. Thanks
