I have seen this link in other threads and have not found anyone that actually tried the stuff. For those of you who have not seen it it is an additive you mix with used vegetable oil. You then build this filtration system that costs about 150-200 in parts from H/D or Lowe's. Most of the stuff I saw in the video I think I already have lying around. then pump the concoction into your tank and away you go. They advertise the cost to be about .50 per gallon. It looks suspicious but for 50 bucks I cant resist. I paid my money and have received the email video of the filtration system it is very quick and vague. The manual that comes with the additive product is supposed to give more precise directions with the video as an aid... We will see. I will update you all when I get the stuff. I would still like anyone else's input that has tried it or knows someone who is?. No, It is not bio diesel completely different stuff they stress this repeatedly.
