I am considering running vegtable oil in my 2003 f250 7.3. My questions relate to two different setups and if anyone has suggestions.

One setup I am considering is to run off-road diesel combined with vegtable oil on a 50/50 ratio. Will this ratio require additional diesel additive to boost the cetane level or am I ok as it is?

The next set-up is mixing vegtable oil with kerosene, unleaded fuel, diesel additive and running through a filter system. If thinned properly so as to not clog anything, is there any long-term effects to the engine that I should be aware of?

Thanks
