I'v been making and running bio since april. I make it in 5gal buckets. It cost me about 40c a gal to make. I get the oil hot from 2 resturants that I frequent. They call me when they are ready to change the cooker and I show up with a bucket. Most friers only hold 4 gal, so a 5gal pail works fine. I have to let it cool a while because of the low boiling point of menthol. (I found that out the hard way.LOL) I screen it, make it, then run it through a 10 micron filter into my tank the next morning. I have run as high as 50% with no problems. There are several recipies that are available. The recipie I use has reduced lye so no need to wash it. I also run it in my wife's Liberty with no problems. Jeep's new diesel comes with 10% from the factory. I am only running 10% now because of the winter here. It makes me nervious with a higher amount. I am actually making more now than I can use. The whole prosses takes about 15min. Since it has got colder here, I include Amsoil's cold-flo to my tank along with their fuel modifier. So far-So good.
