just drove by my fill station for dino diesel and they raised it to $3.39 / gal yet they are lowering gasoline prices. I have been thinking both ways of bio and WVO. I think WVO would be easier to run with a in bed tank and still have the option of running dino in the main tank under the bed of the truck. I was talking to a guy who has a 06 dodge running veggie and he said all diesels can run it. They are installing conversions in all diesels and not had any problems. I just hate to have a problem that would be costly down the road.
