Does anyone have any information about how this new Ultra Low Sulfur
diesel that will be at the pumps starting very soon will impact the
diesels, like mine (2004 Ram 2500 CRD). I may not have a good grasp on
fuel but it is my understanding the the sulfur content, up to 500ppm
currently in the diesel fuel we use is dropping to 15ppm. Since sulfur
acts as a lubricant, I was wondering what impact, if any, it will have.

Sulphur does not act as a lubricant. However, the process that's used to
eliminate the sulphur also decreases the fuel's lubricity. End result is
the same, but it's how you get there that matters :)
Engine manufacturers have known about these coming changes for a while now,
and the injection pumps, injectors, etc. that rely on fuel for their
lubrication are designed to work with the ULSD fuels. It shouldn't be a
Not that long, EPA passed the rule in early 2005 and it would likely
not been a factor at all in a 2004 because it would have been designed
a year or two before that.
Below is a link to some info on low sulpher fuel problems for those
that want to learn a bit more about it and what problems are being
seen where it has been used for a while.
A comment like that tell others how uneducated and close minded you
realy are. Knowledge if free to aquire and it is stupid not to expand
it. A intelligent person considers info from all sources possible and
then draws their own conclusuion AFTER reviewing the info and not
basing conclusion on source.
How about you jump your ass back to the V 10 thread and answer the
questions!! Perhaps you will expand your knowledge. Actually you should have
some knowledge on a subject before you post. Guess we won't be reading
anymore of your BS
Ah ... well I did mention that I was fuel ignorant. :)
After I posted, I continued to search for articles on the matter and
there is some agreement among many mechanics that the increased
lubricity in bio-diesel, if one were to run B20 (20% bio and 80% ULSC),
makes up for the difference. Yet, Cummins won't commit to anything
greater than B5 on engines older than 2006.
It will be intersting to watch it all unfold, I suppose.
Meanwhile, Willie Nelson put in couple of BioWillie (yes ... it is
really called BioWillie) pumps (B20 & B100) about 10 minutes from my
house. I'm gonna give it shot.
You know, I've heard many people say that, but honestly I don't know
how I would be able to tell. On regular diesel (I usually fill up at
Phillips 66/Conoco), my truck does not smoke unless I bury the
accelerator, which has happened ... twice. One of those times was to
see if I could get it to smoke. :-)
Otherwise, there is never any smoke at all. I have even driven behind
it in a different car while the girlfriend drove my truck ... no smoke.
Is my truck an exception to the rule for the 305/555 engine?
uh when I put my foot down on the floor it goes clank. *grin*
yes there usually is no noticeable smoke in normal driving, but I play, a
you've only buried the accel twice??? sheesh! I passed that on the first
Chris, how ya liking the liberty? Give me some info please. Seems I'm going
to be making a few trips a year to FL. My 05 4X4 Cummins is nice, but I'm
getting about 14.5 mt at the speed of traffic. Sure I can slow it down to 60
but ya stand a good chance of somebody driving over you. Kinda playing with
the idea of a change but am not sure that the getting is worth the going. If
it is only 3mpg than of course it is not. Like I said it is just a idea
although probably not a good one. Then again maybe the liberty might be just
the thing for a run around truck for Fl or perhaps for the wife up here.
We love the liberty, tara sees 23/24 mpg on her daily driving, she drives a
lot of highway as her work is in drybranch GA witch is about 30 min away by
interstate. she runs it hard too i bet if i drove it and kept it closer to
70 on the interstate you could see closer to the epa's claim of 30 highway.
it handles pulling the boat fairly nicely for a small truck, and have used
to to move the tractor when i hurt my left leg and was uncomfortable driving
the stick for a few days. so far the only things we've had to do to is, 1
fuse (cell phone charger shorted) and the #3 glow plug shorted and turned
the check engine light on. the ride is surprisingly smooth for such a small
vehicle. the "clack" at highway is a touch louder than in the cummins but
the turbo "wistle" is much more subdued so i guess you trade one noise for
another. but niether truck is anymore obnoxios than the other at interstate
speeds. i still havent had a good oportunity to put the liberty on a trip,
hoping sometime around the 1st of the year we can go and see the inlaws in
KY and put the liberty through the paces.
oh yea by the way, something i should warn you about. the steering ratio is
much quicker than the ram. what would be a small correction in the ram is a
pritty quick move in the liberty. no big deal just takes some getting used
to everytime i get in the liberty.
I checked with Stanadyne as I use their fuel conditioner & according
to them, the lubricity level will be taken care of at the refinery -
just adding another additive?? Someone ask one of the refineries!
