You really have to consider the year, make, and model of truck in this discussion...

I will give you my experience... My 05 cummins.. was very fuel picky... Ran fine and had good power, but some fuels would make her really rattle bad (injector rattle I would guess). I ran 2x dose of power service in that truck every tank (white in winter, grey in summer) and that certainly helped. I ran across a diesel pump in South Haven, MI last summer that had 2 grades of diesel... I used the high octane one and the truck ran like a raped ape!.. I have never again been able to find that blend.

Now, my '14... I have run some white bottle power service thru it for anti-gel in the winter, and I have put the grey bottle in every 5 or 10 tanks... I notice no difference in this truck with where I get fuel or whether I have any additive in it or not.

I think the main difference is 1 truck was designed for ULSD and one was not. If your truck was built before 2007, I believe some kind of lubricity supplement should be used. After that, I don't think there is alot of benefit.

Edit... Illinois by law has to have atleast some bio in all the diesel sold on road... while I like bio in my farm tractors, they seem to run fine on it, I do notice a little mileage hit... Although, bio diesel is great for fuel lubricity, so it will help in them older trucks running this dry fuel.

I'm currently running Opti-Lube Summer blend in my 6.0 Powerstroke and in the winter switch over to their XPD formula. (I live about 11 miles away from them and from work it's even less so it's easy for me to get.)
