Ultra low sulfer diesel problem

[Petr51488]

I got a letter from the place i got my plow at. It says the following.

It has come to our attention that the ultra low sulfer diesel fuel has serious problems. THe new fuel is used to cut back on NOX gas which can not be seen by the eye. The fuel has a condition that lets enzymes grow in the fuel tank very rapid. The result of this is plugged filters, plugged injectors and liner of fuel tanks deteriorating. This condition has caused out truck to fail out on the road. We have cut several fuel filters open and found the waste product of the bacteria in the filters. The fuel also does not have the lubricity factors to keep the fuel injection system lubricated for long term use, and has cause serveral customers to have failures with the injection system. AN example is shown below. they show a filter from a powerstroke. It has black sludge..........Our recomendation is to bring your truck in for a filter/conditioning service.

Does this have any truth to it? or is it just to bring the truck in and make some money.

Um you own a diesel but cant change fuel filters? I have had algae problems long before the ulsd and let me tell you, you do nt want them! It is caused by water in the fuel! I recommend howes fuel treatment and change filters when they should be changed! Hows is so much better than the power service crap! We ran big trucks on the road for years and will never use powerservice again! I cant even tell you how many times we had trucks die on the side of the road with filters full of diesel slush! And was treated with PS the day before! Good idea to cary a spare set of filters and a wrench in a diesel!

Yes, i do own a diesel but dont change my fuel filters. I've never heard of this type of problem but figured something was bound to happen. I usually change my fuel filter every other oil change. The inner fender has to come out in order to get to it. I leave the oil change and fuel filter up to the dealer. I don't have time to work with that. How often do you use a conditioner?

Thanks, but in Jersey we don't have sub zero temperatures. The lowest i've ever seen i think would be 14 degrees. Do you have any conditioners?

Did you read further into the 2nd link. The diesel concentrate is available by itself still (the Cold Flow Impover was recently combined with it) and helps with the lack of lubricity in low sulphur diesel. There is also a Cetane Boost. The link is--

I can't believe it doesn't get that cold there. Our high today was 15. When I woke up this morning it was 3. Oh by the way, the high yesterday was 53 at 3:00 pm. Can you say Alberta Clipper???

Ok, I have been driving diesels for over ten years. Both ford and dodge. I have never have an algee problem. I use Powerservice every tank all year long and change my filters every 15000 miles. I think that there is something else going on here. I think they are trying to rope you in. I have taken my rigs up to old forge NY where winter temps can hit 25 to 30 below at night, plus wind chill. The diesels start like a bi%$h, but never have had fuel lines gel or any other problems. Hey, if they can keep big rigs running in the far north artic, than the lower 48 should be no problem. I say throw the letter out. By the way, you said the plow dealer sent it to you? Is this also your chevy dealer. If not than I think they are blowing smoke up your a$$. Talk to your dealer and show them the letter. Good luck.

They are not my gmc dealer. Their main issue is ultra low, vs. low sulfer diesel. Most of the big rigs out there are low sulfer. Only the new ones are ultra low. I'm not defending the letter, just trying to explain the main point of what i think the letter was about.

[TXNSLighting]

I found a station a while back that had low sulphur still. That was the best tank of fuel i have had in a while. I got 19.6 out of that tank, and the truck was flawless. The ultra low is bad. I have always hated it and been against it. It has robbed us of fuel economy.

[IA_James]

Ignore it. The fuel filter clogging I've heard of with bio-diesel, evidently it makes a little better solvent than straight diesel, and if you've got an older fuel tank it'll break all the sludge and crap out of the tank and lines and land in your filter. Outside of that it's just BS garbage to try and get you in there for service. Newer truck = no problem.

[WH401]

Ultra low is the worst thing to every happen to diesel fuel. They took Low Sulfur (500ppm) down to Ultra Low (15ppm), huge difference. It definately has lubricity problems as I got caught with a partial tank of it in my 92' Dodge and it caused the pump to develop a slight leak. It wasn't just me, lots of people had these problems as it lost it's natural lubricity. It's the same concept as when they took the lead out of gasoline. Taking the sulfur out also drastically raised the temp at which diesel gels now and it also costs every pre-emissions deisel about 1 - 2 mpg. Not to mention the new truck all suck as far as mileage.

The EPA came out with a report a few months stating that they knew all of these things would happen, but what a surprise, the government not caring about the effects. I run Power Service in all 3 of my vehicles, gray in the summer and white in the winter(combats the gelling). They've reformulated PS to comply with ULSD but I wouldn't run it in any of the new trucks. The new trucks are made to run on ULSD so it shouldn't be a problem and it would most likely make your DPF clog faster. The older trucks are the ones that have the problems on it as they weren't designed for this crap.

Cool, problem answered. If your GMC dealer is not saying anything than I think its a safe bet that you will not have any problems. Duramax is a good strong engine, and I'm a Ford guy:hammerhead: Like I said, the plow guy is probably slow from the economy, so they came up with a letter to blow some smoke and drum up some business. Cant blame them, but dont be their fool. I have run my current 04 PSD over 70000 on ULSD with no problems. Power Service is the key. 3oz to every ten gallons. Makes it slicker than possum s%^t, what ever that means. I will say this, buy fuel where the station moves ALOT!!! of volume. The fuel will be cleaner and have less water. Also, drain your water/fuel separator ofter, especially in cold weather. Hope this helps.

[nosparkplugs]

You have been running ULSD since the day you purchased you truck; consequently I would disregard the letter "scare tatics" some one will hurry in to get their filters changed & diesel tune up, just not you.

As the ambient air temperature decrease, and gets closer to freezing, the pour point/cloud point of untreated diesel fuel decrease as well. That means the wax in the diesel fuel starts to form crystals quicker clogging filters & injectors. There are many variables to account for before this happens. Without getting into them, one simple thing or PM. Please I cannot stress enough invest in a quality diesel fuel cold flow improver during the winter months . It's far easier, and cheaper to keep the diesel fuel flowing, than to unfreeze a diesel engine fuel system. The closer you operate your diesel engine to freezing temps the more chance for fuel freezing, simple as that. Don't agree try it yourself:laugh: Diesel fuel additives are preventative, like an insurance policy.

Know your fuel injector pump type & brand, and injector type & style to better taylor diesel fuel additives. These diesel fuel additives requirments vary


I do not add cold flow improver until the temp gets around 27 degree's thats my choice, like I said it's cheaper to keep the diesel fuel flowing than to thaw a diesel fuel system. I use AMSOIL HPI 2 stroke outboard motor marine DFI TC-W3 oil in my #2D 1/2 to 1 quart per 35gallons, that is only b because the Bosch VP44 fuel injector pump is totaly fuel lubricated. I also add AMSOIL ADFCN diesel concentrate per 35 gallon fill up. AMSOIL ACFCN cold flow improver per 35 gallon fill up ONLY during the coldest months. Personally I have used the AMSOIL Cetane Boost ACB05 5 gallon pail:laugh: great product, but I did not see any improved MPG, just more heat EGT & torque this stuff was addictive for me so I had to quit using it:clapping:. The Cetane is like Octane boost for diesel, but if you add to much Cetane number 65 or more:nono: you'll lose BTU's with diesel.




Here's some reading on ULSD enjoy.

Algae is real! Trust me, I have been there and done that! I never want to go down that road again! Laugh all you want and claim it is fake but it is not. Go talk to any diesel mechanic and they will tell you what i just said. Once you get it in your tank, you will believe me!

[SpruceLandscape]

I've kind of stuck in the middle. My 06 ram is designed to run on Low sulfer, diesel, not necessarily the ULSD. I am in luck that I have a speedway near me that refuses to sell ULSD and sticks to the low sulfer instead, but they are usually $.10/gallon more expensive. Otherwise, I us PS every other tank in the summer and every tank with the White in the winter unless temps are supposed to stay above freezing for a while. Haven't had any problems so far and I just clocked 43k on the truck. I change my fuel filters every other oil change, and at least drain the fuel filter every oil change. I am in luck though, the dodge is about as easy a fuel filter to get to as anything I have ever had.

Your confused all modern diesels will run on ULSD with zero modifications; especially your 06 common rail Cummins ISB, the Bosch CP3 injector pump requires zero fuel lubrication. The Refineries switched to 100% ULSD production in 2006, so your Speedway station "refusing" to sell ULSD frankly, does not add up?. Even the off road diesel is now ULSD without the road tax, and is still dyed red. The only "low sulfur" diesel out their is old stock that framers have or marine terminals with huge storage tanks, to fill marine vessel's:laugh:

While they will run on it, using an additive in you fuel is a good recommendation on any truck made prior to the 07' emissions standards. It will replace the natural lubrication properties that high amounts of sulfur exhibited, as there is a definite lubrication problem with ULSD, and using an additive will also give you back part of that MPG you lose while running it.

It isn't until December of 2010 that all on-road fuel has to be ULSD. 80% of the diesel produced in the US is ULSD and you can still find LSD at truck stops. I know of one that I stop at on 301 North headed towards Delaware and they still have LSD. It definitely is hard to find though, as most places only sell ULSD, but it is still attainable.

Off-road, locomotive and marine diesel was just down graded in 07' to 500 ppm, and won't be required to be ULSD until 2012-2014. I can still get off-road, with 500 ppm, right over in the next county at the Shell.

[nosparkplugs]

As of 2006 US refineries were required to switch their diesel stock to 80% ULSD, that only leaves 20% of the total Low sulfur US diesel fuel stock left. That 20% is in off road/marine diesel, and it's availability is spotted across the country.

Early ULSD did lack some lubricity; however that has been corrected. Some diesel additives/lubricants contain high levels of paint thinner(napathene) or xylene. Doubting that??? I suggest pulling your snake oil MSDS sheet before debating this with me.:laugh:

Sulfur is not a lubricant, never was.

Sulfur is not a lubricant in of itself, but it can combine with the nickel content in many metal alloys to form a low melting point eutectic alloy that can increase lubricity. The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally-occurring lubricity agents in diesel fuel. To manage this change ASTM International (formerly the American Society for Testing and Materials) adopted the lubricity specification defined in ASTM D975 for all diesel fuels and this standard went into effect January 1, 2005.

500 ppm off road is still readily available across the country. Go on over to tractorbynet.com and read up on the number of people still using off-road for everyday use in there tractors, there's quite a few of them.

I know full well though that for example, Power Service, has xylene in, but if you have proof of PS causing fuel system failure, I'd love to see it. I know there would many interested readers on the various Dodge Cummins forum's that have run hundreds of thousands of miles with PS, or another additive, in the tank, without any issues.

Current ULSD, still has lubricity issues and the oil companies have not done much of anything to fix it. Not to mention the problem it has caused with fuel gelling so easily now from the cold and the fact that algae is able to grow much easier in this environment. Yes, ASTM adopted D975, but even though it went into effect 1/1/05, nothing obviously was/has been done to diesel, even if the problems associated with ULSD were only in the beginning. Taking the sulfur from diesel has caused in essence, the same problems that were found when the lead was taken from gasoline, you lost that natural barrier of protection.

[nosparkplugs]

No I agree with you on farmers using ULSD, their using their own storage tanks, and having it delivered.

I was originally posting in regards to Sprucelandscape saying he has access to on road non dyed low sulfur diesel, and the Speedway refusing to sell ULSD for onroad use?.

No reported failures with PS, when the MSDS sheets on all diesel fuel additives were made public, and easily found with the WWW. I immediately stopped recommending or using any additive containing napatane or xylene, acetone etc. Those chemical compounds are less of a lubricant and more of a cleaner; hence their are better products for specifically adding lubricity. PS will continue to maintain a diesel additive market share, but many folks I know stopped using it, or are questioning it's content's. PS will clean some dirty fuel injectors look at whats in it.

I would recommend taking a diesel fuel sample from your main filling station. Send it in for analysis, then you'll know the exact lubricity number for that fuel batch. I've yet to find any ULSD with lubricity below ASTM D975 standards; however I still add 2 stroke outboardmotor TC-W3 oil to my diesel fuel for added security my Bosch VP$$ thanks me

[Magnum Services]

I run Power Service Cetane Boost in my truck . A quart every fill up and have NEVER had a fuel related problem .

nosparkplugs, according to info that has recently been discussed at the dodge diesel forum where you and I are memebers there is a Citgo refinery in Texas that is 100% lsd and is sold as non dyed on-road fuel. I haven't ran across any but there seem to be several guys there that have been running some.

[dwc]

here is a link to the Schaeffer's diesel treat 2000 that we run in our diesels. It is amazing how much smoother they run on this stuff. Only cost me around 75 cents a fillup to treat the fuel. I also run their oils in everything.

Small world. These stations are talked about like the dying breed their becoming. Most of the stations selling LSD, end up being false, yes their some out there. Some stations still have the old LSD stickers on the pumps too, that add's to the confusion. Regardless the change to ULSD happened in 2006 for the majority of the country.

[SpruceLandscape]

while I'm sure you are correct in your area of the country, the speedway that I am referring too absolutely is selling LSD and not ULSD. I can not attest to the fact whether it is dyed or not, but, the current state auditor's sticker on the pump is a 2008 sticker specifiying LSD fuel for on-road use not to be used in model year 2007 or newer diesel engines.

Nothing personal your obviously paying attention, try asking the Speedway hw long their going to be selling the LSD. What the LSD running per gallon$$ I'm paying $2.39 for ULSD:cry:

What made you think your Cummins cannot run on the LSD? You should be having ZERO problems, and should you switch to ULSD a slight loss in MPG & power

[PLM-1]

Here are the results of an HFRR score test with ULSD and which additives work to improve the fuel. The chart is at the end of the reading. I use schaeffers and am quite pleased!

http://www.dieselplace.com/forum/showthread.php?t=178848

[SpruceLandscape]

quite the opposite. I'm not complaining of how my truck runs on the LSD at all! I would much rather run that than the ULSD any day! As a matter of fact, my owner's manual even recommends it. While I'm not sure about the MPG aspect because my driving fluctuates so much from tank to tank, I'm sure that its either close or slightly less with the ULSD, but hard to tell in only 34 gallons at a time

[SpruceLandscape]

lately fuel around here has been staying pretty much in the $2.50-$2.60 range, depending on which county you are in. But on average the LSD has been running 8-10 Cents per gallon more. Of course, there is only the one station that I know of nearby that sells it, so it may be more of a supply and demand rather than market price thats kicking their price up.

[GravelyNut]

Algae is real! Trust me, I have been there and done that! I never want to go down that road again! Laugh all you want and claim it is fake but it is not. Go talk to any diesel mechanic and they will tell you what i just said. Once you get it in your tank, you will believe me!
One former Diesel mechanic/operator reporting as requested. :waving:

Bacteria in Diesel fuel has been around since long before the switch to even LSD was made. It doesn't take much water in a tank to start it growing. It actually starts while in storage tanks before being delivered to the stations. It actually was a bigger problem with regular Diesel as the bacteria loved the sulphur. It is not an algae. We had to drain our fuel tanks monthly of just the water that condensed in them. And then a little more to get some of the bacteria out. When we switched to LSD, we still had that problem. We always added Biobor to it to kill most of it off. And inspected the tank trucks to make sure when we got to the bottom of the tank compartments that there was no water there. Even with that we still got primary filter clogging. The primary filters ( dual switchable while running ) lasted about 6 months at most. But then we had a secondary primary/ final filter set on each engine also plus a Day Tank. The heat from the engine killed off the last of the bacteria in the Day Tanks and the sock/final filters kept it out of the engines. Our day fuel tank temps ran at about 160°F. Still had to change them at about 1000 hour intervals. But by then we would have burned somewhere between 10 and 12 thousand gallons of fuel per engine. At the other stations, we could burn thru 7500 gallons in one day with even larger filters. Open one up and you'd find the same brown slime.

Yes, i do own a diesel but dont change my fuel filters. I've never heard of this type of problem but figured something was bound to happen. I usually change my fuel filter every other oil change. The inner fender has to come out in order to get to it. I leave the oil change and fuel filter up to the dealer. I don't have time to work with that. How often do you use a conditioner?

can u not just take the battery out and get to it from the top?? thats how we do it on our 06, idk if the design is any different for the 08 but i doubt it still being the 6.6

sounds like a load of crap to me. we just take out the battery and its easily accessible from the side! well not easily. but its possible with a little bit of twisting

[TXNSLighting]

Going through the fender was the easier way. ( i dont pull it all the way off) I dont want to have to take that dang battery out...

yea i did it like that once (once) and i spilt the fuel in it all over myself. so i resorted to the up top method.

One of the many advantages to a in line six design easy maintenance. the Cummins 5.9L ISB 02-07 fuel filter change easily visible on side of engine 1.) open hood 2.) unscrew filter cap 3.) remove old filter from cap 4.) replace new filter on cap 5.) tighten cap. I change my filter while filling up the truck sometimes.

I waited too long for mine:dizzy: drove around GM diesel's 6.2L 6.5, then tried Ford out the 7.3L Powerstroke. After those diesels I would switch just for the ease of maintenance alone. The stock oil filter is located on the side of the block, it too is changed from under the hood. Once the engine oil is drained you don't have to get back under the truck again.:clapping:

[westcoh]

You guys are making that fuel filter out to be more work than it really is, assuming it's the same design as my 05. I can change it out within 5 or 10 minutes without having to remove the battery or fender. It is a bit awkward, but can be done.

There's an article at The Diesel Garage that tells how to do it, but the forums seem to be down right now so I can't find it.

One of the many advantages to a in line six design easy maintenance. the Cummins 5.9L ISB 02-07 fuel filter change easily visible on side of engine 1.) open hood 2.) unscrew filter cap 3.) remove old filter from cap 4.) replace new filter on cap 5.) tighten cap. I change my filter while filling up the truck sometimes.

The powerstroke is even easier. Its right on top. The dumbasses who designed the duramax coulda made it much easier but chose to be dumbasses.

On the 08 duramax the person who designed the fuel filter location should be fired, have to take off the plastic in the fender or pull the battery is bs. If they only made it alittle lower towards the frame it would make it so much easier. Sometimes I think they do it to make it harder for us so we have to take it to the dealer. There was a good write up on the duramax forum about making a access panel in the wheel well palstic so you don't have to take it out.
