One of the advantages of the un-taxed fuel in some instances is it still has the much higher sulpher content than the fuel for on road use. That sulpher has the beneficial side effect of greater lubrication to the fuel system components, benefiting the injectors and o-rings. However, in some parts of the country even the un-taxed/off-road fuel is now the ULSD.
I've heard reports of D.O.T. stopping all of the trucks on their way into the cattle auction and dipping the tanks; some guys had fines to pay.
A guy that I works with, so yes, this is a second hand story, told me that his uncle was getting on the interstate and based on the exhaust when he accelerated on the on-ramp an off-duty D.O.T. officer not even in his local patrol area had enough suspicion to call F.H.P. to have him pulled over. They made him pull his fuel filter in his 7.3. When it came out red, a fine was issued.
I have no idea how the color or smell of the exhaust could indicate dyed vs. non-dyed fuel, but he was caught and got a BIG fine.
Also, I know of several who run used transmission fluid as fuel in their on road diesels. The argument goes that so long as it's a "supplement" it does not need road taxes paid on it. Various arguments as to at what percentage it's no longer a "supplement." 5%? 50%? Anyway, I wonder if the onus would be on the operator to prove the red coloration is from ATF in the fuel rather than dye?
