What is the difference in this fuel vs the other stuff? It is a "premium" diesel and is $0.04 - $0.10 more. Is it worth the extra $? Just trying to decide. I have heard some people say it is the best. I have not tried it yet.

I believe this is just what Cenex calls their premium diesel. For some reason, you don't see it a lot, but it is fairly common in Montana I've noticed. I've run a few tanks of it, and I do think that it gives me slightly better milage. On a recent trip from Billings to Bozeman, I got 17.5 MPG in my LLY cruising at 70. Normally I would get more like 17 at that speed. At that particular fill, the Roadmaster was $0.05 higher than regular.
