I just read a question about the amount of taxes paid by Exxon. How about the taxes on BIO-FUELS?Did you know?

I recently bought a machine for the conversion of used, clear vegetable oil to bio-diesel. But did you know that I'm responsible for paying the TAXES on the fuel that I MAKE? I have to pay the state highway use taxes on each gallon, and the federal gasoline tax on each gallon, in order to not be violating the law. Seems a littel like double taxation to me, adn therefore illegal, and I refuse to pay this. But did you know if you make your own fuel you are SUPPOSED to pay taxes on it? I paid taxes on the conversion chemicals, and the restaurant paid taxes on the purchase of the oil. To have me pay taxes on their combination is double taxation, and is prohibited by the Constitution. But there was a notice with the machine that had a warning to that effect from the federal government. Just another example of Liberal Democrats and the Big Government putting their fingers in everything. My car will run on moonshine. If I make corn liquor should I have to pay taxes on liquor AND gas too?
