Honestly, I don’t know.
Most of my acquaintences on the local PF know I’m making biodiesel and soaps, so they leave me alone - unless they want to try out my degreasers, which I give away. I sell NO product or by-product.
My State Legislators passed a law in ‘07 making all biodiesel made in one’s backyard for use in their own vehicles registered in their name EXEMPT from all taxation; net result is homebrewers enjoy the same tax exemption the FedGov is accustomed to. I call it smart on their part to exempt motorfuel moonshine to help starve a Persian Gulf terrorist.
Also, the FedGov screwed themselves and tied their own hands, saying in order to claim a 50 cent/gallon tax credit (using waste oil), one must have an expensive ASTM test done declaring the product fit as a motor fuel. So, if the IRS pursues anyone for failure to pay highway tax on biodiesel, they are, in essence, saying the government (the only agency the IRS has the authority to represent) recognizes the quality of the homebrew product as a motor fuel, thus the tax credit that exceeds the motorfuel tax should have been applicable.
But, those are seperate topics.....

Can you point to a recipe?
