I have an 06 PSD with about 3k miles on it. I added some Diesel Kleen (50 gal treatment for 29 gal tank) yesterday and topped off the tank with 17.6 gallons. I was out driving around and being fairly aggressive with the throttle. While sitting at a light I noticed a bit of smoke behing me, I figured it was the car behind me. I got out and looked and realized it was light blue smoke coming from my truck. Is it from the diesel kleen being over concentrated? Is it from being aggressive with the throttle? I haven't noticed it since, should I be concerned?
I have never seen / heard that over medicating would cause this.
Could be that the diesel kleen was....cleaning.
BTW: The value of higher cetane plateaus at around 50 / 52. Except for some added lubricity and cleaning properties there isn't much to gain by going overboard.
the story from ford is, additives with kerosene somewhat thin the fuel to the point of injector damage. The fuel inside the injector dampens action by the piston, so its not slamming the top of the travel. The 03 6.0 was experiencing this when they would leak fuel into the oil system(not enough left inside for dampening). Different additives use varying amounts of kerosene, so the best advice is use the amount on the directions. We all know how sensitive the 6.0 is.At least thats the story I've been told.
I do not like the new Ford additive (part #PM15) is that it is mostly Kerosene, yet Ford states not to mix keresene and the like with deisel (as many used to doe for winter anti-gel operation)... yet their additive is mostly just that!!!
Based upon what I am reading in the above link, I am not sure what lubricity is in this product and the kerosene would do more for cleaning than for cetane boost and lubricity.
If he's blowing blue smoke, and he's only got 3K on the clock, is it possible that the rings aren't seated in yet and there's a little oil getting into the combustion chanbers? I know diesels are supposed to be tighter than a tick, but is this not a possiblitly?

Then it would seem that the heavier the kerosene content, the more careful one should be with keeping within the label doseage instructions.
