I was a diesel mechanic in another life after the military. I know of red diesel. I also frequent areas were Leo wouldent dare try and dip your tank.You do realize many states have entire law enforcement agencies who do nothing but pull people over and check for unlicenced diesel fuel aka farm fuel. Its a multi tens billion dollar enterprise. Hell micheal franzesse became one of the richest mob guys in NY running a scam selling untaxed fuel in th new york area for decades. Made billions for the italian and russian mafia.
Never heard of dipping a tank?
When My family is hungry enough for me to take a “illegal” moose do you really think I’m gonna let anyone but the God that told me to provide for my family tell me I can’t? Do you want to volunteer to be point man when gov goes to kick in the door of someone who has kicked in the door for the gov? Do you think a polymer 80 kit gun is gonna be the only thing behind that door?
