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....:wtf:

[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? :think:

[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....:whatever:

[fireferg73]

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?

[dozerboy]

More than you ever wanted to know about ULSD (http://www.eia.doe.gov/oiaf/servicerpt/ulsd/pdf/ulsd.pdf).

hell ya! or y not just manufacture pure biodiesel? i know full well that it mixes with regular diesel degelling additives, i used to make my own bio during the fall/winter/spring, no problems except for smellin long john silvers every time i was at a red light for more than a few seconds (makes u really hungry). its cheap to make, the emmisions are minimal and if you adjust your timing slightly your emmisions are almost nothing. can the US produce enough for all of our diesel engines to run on b100? yes. we would have to stop telling our farmers to quite producing at 50-80% and go up to 75-85% or their production ability, but theres nothing wrong with that. and all the extra crops that we waste? and used vegetable oil? i spent 45-50 cents a gallon after i set up my methanol recovery system and i never had any problems. lubrication ability of biodiesel? as stated before its wonderfull. its not hard to produce, helps OUR COUNTRY, not the middle east that wants to kill us. biggest downside is that our oil companies will suffer (ohhhh nooooo!!! the rich *******s will lose money!!!! :D )but they could make money by being the ones to refine it, distribute it, and produce it. so guess what, they would still be rich, and not have to spend a fortune on oil from the middle east. does this make sense to anybody else? or have i gone insane?

[LostBoy]

...does this make sense to anybody else? or have i gone insane?
I think it makes sense to everybody but the folks that line their pockets w/ oil industry profits... Unfortunately, they're also the ones that are making the calls. They're rich & getting richer, whereas biodiesel may or may not be as profitable - why would they mess w/ that? I don't see it happening on a wide scale unless enough people start making & using their own to cause a significant loss to the oil industry.

[bigmatt]

ulsd is being mandated to allow the use of paticulate trap type aftertreatments. The fuel along with low ash oil. Ash depsits from oil burn off will also clog your new style cats.

Thank you for asking Chevrolet and for your interest in Low Sulfur Diesel!

Diesel-powered engines for 2007 and later model year highway vehicles are designed to operate only with Ultra Low Sulfur Diesel (ULSD) fuel. Improper fuel use will reduce the efficiency and durability of engines, permanently damage advanced emissions control systems, reduce fuel economy and possibly
prevent the vehicles from running at all. Manufacturer warranties are likely to be voided by improper fuel use. Additionally, burning Low Sulfur Diesel fuel in 2007 and later model year diesel-powered cars, trucks and buses is illegal and punishable with civil penalties.

Please be advised that the 2007 Chevy Silverado Classic equipped with a Diesel Engine LBZ can use either the Low Sulfur Fuel (LSF) with 500 PPM or the ULSF with 15 PPM.

My brother in the refinery industry told me a little about the ULSD. Apparently there is a new type of hardware that is going on the new trucks. He also said if you put in 1 tank of High sulfur or low sulfur it will plug up this "thing." This thing isn't cheap either around $2k to fix.
The good news is that this is the only fuel that will be available except for locomotives. I don't know if the ULSD will be dyed differently. I know the Loco fuel they use where I work is Kool Aide red.
Talking about BD he mentioned that they had some engines they ran on BD. These Engines developed Lubrication problems. I tried Mystic Synthetic blend oil in my dads truck and that took care of a valve tick that lucas, marvel, and slick 50 wouldn't.

The new thing he's talking about is a diesel particulate filter. It does just like the name implies and catches particles in your exhaust stream and stores them. Constant monitoring of the the DPF lets your computer know when it is getting "full" and it runs a cycle to clean it by cranking up EGT to burn it all off. All the OEM's say they're good in excess of 150,000 miles, so conveniently they'll last you for a bit outside of your warranty

When I was in Wisconsin with the bus company we switched to ULSD. We went through about 10,500 gallons of fuel a week. We ran the stuff in diesel motors as old as 1998 and as new as 2005. (No 2007s, YET) And the only problems we had was fuel filter clogging in the Ford/International DT444Es. But that's because they have a relatively small fuel filter. Our International DT466Es would clog too, but not nearly as often.

In Illinois, where I am now, we have to run bio-diesel by law, and I still have no opinion on bio-diesel. It seems to do pretty good, but I haven't been here long enough to see any issues. Of course, here we change fuel filters every 9,000 miles. Mostly because of the Cummins 5.9L POS. :D

[dozerboy]

All diesel will be ULSD red dye diesel is for off road use only but is still ULSD.
