Fuel differences?

[joedaddy_43]

How does D.O.T tell the difference between red fuel(no taxable) and clear fuel (taxable) with A.T.F. or marvel mystery oil added to the fuel for lubricant?

they cant, what they do is stick a clear tube in your tank suck a little up and take it out, and if its red your screwed. if your doing it on your own personal truck you should be fine, ive never heard of anyone getting dipped without owning 5+ trucks around here, there mainly going after businesses that report alot of fuel being used for off road. What they is, they buy the diesel and pay taxes on it regardless of what its going in. then they have to document what goes into on road and offroad vehicles and get rebates at the end of the year.

if you want to get technical though even if you say its atf, they can nail you for using a non dot/epa approved fuel. this is starting to happen in california with bio diesel

around where i'm at there are a lot f vineyards and the check every truck that drives by the check point. One or two times a month. I also cary a 90 gallon weather gaurd fuel tank for fueling equipment and i run either A.T.F. or marvel mystery oil in every tank of fuel i get for my truck but i don't wont to git introuble for red fuel if all i'm doing is adding a additive to my fuel.

ive been dipped tons a times in the year and a half i owned my duramax. if the fuel comes out red, you get the big fine. you can try to contest it but good luck. your best bet is to not even try. if you contest it, they have to send a sample of your fuel in for testing to see if it is red diesel or an additive
