Anyone Use Power Service Cetane Boost
I have read on a blog or two that using Power Service Cetane Boost helps diesel trucks run better. Anyone here use it? Does it work like they claim? Is it worth using on a 2012 F250 or just on olde...

I believe there is a minimum cetane level that all diesel fuel needs to meet. I don't think you will find any diesel fuel that is below the minimum that is required for your truck.
I don't think we can assume that. Check this reference:
Cetane - Wikipedia
It will depend on the state where you buy the fuel, and the manufacturer of the engine. I don't have a reference at hand right now, but I know that Navistar designed their diesel engines for an optimal cetane rating of 45. In many areas of the country, you will routinely get diesel with a rating lower than that. Legally as low as 40.
We're fortunate in CA that they are mandated to produce fuel with a minimum cetane number of 53. Even so, if I have run a tank without any additive, and then add a dose of either DK or Optilube, I can hear the reduced diesel knock. Even on top of, I assume, fuel with a CN of 53.
But mostly I am interested in increasing the lubricity of the ULSD fuel, because of the finicky injectors in the 6.0. That is why I stopped using DK, which was easy to pickup at Walmart, and switched to Optilube that has to be mail ordered. Having popped for a few injectors already, I'm doing what I can to maintain injector life. This is the price we pay to drive the last of the best diesel engines.
