Diesel fuel law?

[Sierra Stud]

I went to fill up and noticed a new sticker on the diesel pump, stating " Low sulfur highway diesel fuel. Federal law prohibits use in 2007 and later vehicles and engines. It's use may damage these vehicles and engines". I know there is going to be higher emissions standards but....

[chrisk1500]

Government is forcing auto manufacturers to produce vehicles that will only run on ULSD.....emissions reasons I guess...do a google search for ULSD and you will have more than enough reading for one evening...

[Chuggernaut]

What if you're on vapors and those are the only pumps around?

[chrisk1500]

You *might* be ok....probably some kind of additive available that would help out a bit....don't know what that would do to the warranty though....watch the price of 06 diesels go through the roof seeing as how the 07's are going to have a ton of emissions crap on them and can only run on ULSD....

The big three (Ford/Chevy/Dodge) have been running emissions equipment for the last few years. Ford, since at least 03(I had an 03 PSD 6.0L)
This is causing huge problems for diesel owners. Think about it, diesels produce soot and soot kills emissions equipment(mainly EGR)
That is the reason I got rid of mine.
The new "ultra low sulfur" fuel will work in the D-Max, PSD and Cummins, however you may have to use an addative like Stanadyne or Power Service to help with lubricity.
You can all thank the People's Republic of Kalifornia for this!!

This isn't all bad:

For the last two weeks we have been getting complaints of low power, stalling, and shutting off.
We have been selling some Lucas fuel enhancer to help.
But the problem is going to be around until they do something.
You just cant chage the on road fuel mixture like that and not expect problems.

Here's the scoop on the ULSD.

Pre-2007 engines did not use any kind of aftertreatment devices in the exhaust. 2004-2007 engines used cooled EGR to reduce NOx, and reformulated oil to cut down on soot.

2007 and later engines use catalysts to reduce both soot and NOx. Sulfur in fuel "poisons" those devices and renders them unusable.

Right now they are in the changeover phase for going from 500 PPM to 15 PPM sulfur in the distribution system, which may be accountable for complaints of low power, or (as happend to me) plugging of fuel filters from contaminants dredged up from the bottoms of storage tanks.

As of October 15 (I think) all fuel sold will have to meet the 15 PPM standard. You may be able to find some old stock on the 500 PPM standard, but anything in truckstops or other fueling points that move a reasonable quantity of fuel will be of the 15 PPM standard. And I've been led to believe that there won't be the compatibility issues that there were 10 years ago when we had the 5000 PPM to 500 PPM changeover.

what about if you have an older diesel than an 04? couple of my friends trucks have been running alot louder in the past year, anything they can do (and me soon as well) to fix this?

[chrisk1500]

Run a lubricity additive...that's what I'm doing....

[Troller]

There is nothing to worry about if your running an old diesel, just maybe find a good addative.

From what I have read and studied (I am an environmental system engineering student) the new low sulfur fuel is "supposed" to have better lubricity than the old diesel due to addatives put in at the processing plant. We will see...

You can always make soot. It would be wierd not to be able to create the soot cloud on the little Honda with the big wing.

[restoguy]

Need lubircity? Add some Bio-D! Just 2% bio mixed in raises the lubricity of regular diesel 88%!

[rubikid]

what could a problem in the older diesles running the new fuel could be fuel system seal or gasket breakdown. should check the manufacturers specifications. it was a bigger problem 10 years ago in the lowering of sulfer content as stated earlier. uh, so i've heard.

im new to diesel and am looking to get a used dmax next year... what will this new fuel do to the power of the diesels ? will you still be able to tune them and work them to big power numbers safely?

Nothing, yes

[the moose]

sweet.

with all this talk about running cars on all kinds of funky ideas of fuel, like e85 and blah blah. why not just run everything on bio diesel or a blend of bio diesel and the new diesel?

I don't have the attention span to read all of that, holly crap.
