All commercially available ULSD fuel SHOULD meet a wear scar score of 520 microns.

Results vary from station to station and I believe that is more of the exception and not the rule. I also believe if you are buying quality fuel from a reputable station it more often than not it meets the min requirement.
Think about it, a station would have to sell diesel fuel with a wear scar score of 581 for Power Service not to be effective and bring the HFRR within acceptable limits. A 61 point improvement should provide more than enough lubricity for any deviation unless of course you happen to fill up at that freak station selling diesel fuel with no lubricity additives. From my perspective Power Service provides more than enough benefit.
Certainly you are entitled to your opinion regarding the benefits of Power Service, but from my perspective it is certainly good enough and better than nothing. If you want a product that provides even more lubricity buy Opti-lube.
