Are any of you guys running your diesels on the offroad(pink) diesel fuel??? Or all on road(green) fuel. I only ask becuase if the truck i end up getting is out of warranty, im gonna be more than likly running the offrd fuel in it, since we get it cheap at our farm. I never really figured theres any difference between the two, except for the dye, correct? Theres no power gain or loss between the two?
