When I visited the refinery, we got to talking about fuels. That's where I learned about how they run #2 three different ways. As long as it meets the spec., it can be labeled that way. So, I don't see how they can get in any trouble for doing this.

As for K1 and D1, you might be right. I am just relaying what I was told while doing my inspections. I have no reason to doubt them, but I coulda been given bad information or misunderstood what I was told.

As for additives, I still think they are a good idea with each fill.
