U.l.s.d. ???

I just filled up with what i know to be my first tank of ULSD and it already feels like my truck has less power. It also feels like its "jerking" when driving at "lower"/around town speeds. Has anyone else noticed this problem? I havnt been able to add my DK to my last to tanks of fuel either. Will that fix the problem? Thanks?????????

ULSD fuel is known to have about 1% less energy, but I doubt you would feel it when driving?

Jerking and such is a plugged fuel filter, over-filled oil (foaming of oil when used my injectors), EGR valve or turbo?

I have used ULSD fuel for more than a month with zero problems. My mileage has been within .5/mpg of before and most of that is with extreme changes in outside temps. I still use double dose of Powerservice in every tank and so far... I have noticed no changes in my driving experience in over 5 tank fulls of ULSD fuel.
