Well men....the way the federal law reads....any person operating a passenger or commercial vehicle that is not paying the "road tax" at the fuel pump is essentually tax evading and can be tried for tax evaision.
Think about it.... if you are operating a vehicle on anything other than taxed fuel on state and federal roads you are tax evaiding. That includes alternative fuels like WVO, virgin oil, electric batteries, solar and methane from pig poo....... The laws are so out of date and cannot realistically be inforced for passenger vehicles. The only worry regarding the use of high sulfur red dyed diesel would be passing the state emission tests if your state requires one like Massachusetts.
Cheers,
