Is this the dyed K1? I'm not going to criticize anyone for the tax evasion issue because that's none of my business but if it is dyed they can find you out and if they do the savings will be out the window and it'll be a bad day in your part of the world. I actually tried to find the K1 without the dye here in the winter time to use to cut my biodiesel for winter operation but nearly all of it here was the red fuel, where I did find the clear K1 it was a good bit more than diesel. I would have been ok with that at least as an experiment because my fuel was cheap and it probably thins the bio out a little more than diesel but not with the risk of the 10,000 dollar fine.
