If in doubt pull the nozzle out enough to see the fuel, if it is Greenish in color, it's ULSD.
The occassional tank of LSD should cause nothing more than more active regeneration in the exhaust system, and certainly not cause the truck to shut off.
Plz keep us up to speed on the outcome and solution of your situation.

According to Ford, during a regen one can expect white smoke (normal) and especially when new an "unusual" smell from the exhaust. Regen will occur before 100 mi when new, but will from there on out occur between 100-600 mi depending on driving conditions. Regen will also take between 10-40 minutes and can occur at idle. Ford states that if the vehicle is driven a constant 38 mph or greater during regen it will shorten the regen cycle. On another note, idle will be kicked up to about 1200 rpms during regen, upon pushing brake will drop to within 50 rpms of normal. One can alse expect a different exhaust sound coming from the motor during the regen. I believe I also read that HP is limited on all models to 325 during regen process.
Read the Ford TSB advising customers what to expect during a regen, I might have missed a thing, but the above should be pretty close to exact.

I would say everything here stated so far is true...an occasional tank most likely won't hurt. Thats good to know because there are a few stations in the Little Rock, AR yet to have ULSD...only a few but still there are some.

LSD contains more Sulpher and provides more BTU's of energy per unit burned, that' s the major difference between that and ULSD.....ULSD's contain additives for lubrication, contain less Sulpher and burn with less energy, those are the major differences the way It was explained to me.
The only problem in burning the LSD in a vehicle designed for ULSD is the particulate filters on the vehicles so equipped.
"guthrie&co", understanding the truck and the fuel it is designed to burn helps all of us do our own sort of diagnostic's before we go to the garage, like most of us like to do!
Really not much diffrerent from thorwing the directions away before building something....lol, it helps us understand if they're blowing smoke up our butts.
I was just reviewing the TBS 07-04-11 on the Active Regeneration and it refer's to Stopping......Well here's what it say's.
**Powertrain sound will be different including air induction noise (including flutter on deceleration or engine shutdown), exhaust noise, and changes in engine radiated noise.**
Heck, here read it yourself: http://www.motorcraftservice.com/pub...sb07-04-11.pdf
Kind of sounds like what he described, and Yes it does involve the Fuel! Active regeneration occures with fuel being injected into the DPF..

The only thing I know for sure is that the sulfer content in LSD will result in sever corroision in these newer diesels with the emissions/particulate filter systems, you might get away with running the LSD but not for long....that particulate filter is expensive. Anyways I hope the guy who posted this thread got his truck fixed.

The aftertreatment system (DOC/DPF) reduces the emission of particulate matter and the nitrogen oxides, but doesn't have the ability to beak down sulfur.
As said earlier the new fuel, and oil has less sulfur content for these reasons.
Use of the old fuel 'poisons' the diesel particulate filter (DPF).

First off the ULSD has very little to do with the actual engine, it's not going to ruin the engine it's going to ruin the emissions equipment. Think of it in terms of unleaded VS leaded gas for those that remember. you could run leaded gas through the emissions vehicles all day long and NEVER do any damage to the engine, but one tank would burn up the cat in a hurry, well LSD will do the same thing to the particulate filter but won't hurt the engine itself.

It's the same kind thing that went on with refrigerant R-12 and it's far-inferior replacement. If you know about that, then you know about LSD/ULSD.
