Hi all. I have been searching for a place close to me , 150 miles or so, where i can buy B50 or B100. I did google but isnt coming up with much other than B2. I live in south central South Dakota and I want to buy some . I have a 125 gallon service tank in my pickup to fill so im willing to drive a little to get it. With the price of dino now I figure if I am going to pay a lot of money for diesel Im NOT going to give it to the dino oil companies. I am interested in making my own but would need to see someones operation first to understand it and get a feel for it. Im not sure how readily available cooking oil would be here. Any help or advice would be greatly appreciated. Thankyou
