I came across a site where a guy was using his own custom setup. He was pressing sunflowers and mixing the oil with gas to thin it out and run it in his gleaner and his dodge cummins. He claimed a 50% fuel increase compared to #2 on the gleaner and went from 16 to 24 mpg in his dodge. I know these claims are completely false, but is there any truth at all that mixing gas and veggie oil is better than straight WVO or bio? I highly doubt it, just curious if there is any truth in what hes sayin.
