Aklim the point about impact is a cost evaluation. the money they do not pay (legally and legitimately) on diesel since they are NOT BUYING IT is small compared to the COST to try and hunt these people down (I guarantee you the state has ALREADY spent more taxpayer dollars going after them probably just paying those 2 agents than the tax they are likely to have spent in there lifetime on diesel fuel) PLUS the BENEFIT they produce to the state ALSO exceeds the value of that tax lost. (low fuel dependancy environmental impact both on burning veg instead of diesel (I am assuming its cleaner??) AND
Plus they simply do not owe the tax UNLESS they were buying offroad diesel. its a SALES TAX. if you do not BUY IT you do not owe the tax. Period.
Its NOT illegal to put vegetable oil in your car and they will NEVER pass a law making it illegal as there would be too big an environmental backlash. I also do not foresee them succeeding in TAXING it UNLESS your selling and distributing it.
