So what does everyone think about this article in the Anchorage Daily News???



Wednesday, Jan. 9, 2008



ANCHORAGE, Alaska -- Mechanics are reporting a major influx of diesel engine-related issues due to changes in the fuel's sulfur content.



The issues can amount to thousands of dollars in damage to a vehicle's engine.



Ryan Redington is accustomed to challenges. He's an Iditarod dog musher with more than three dozen dogs to take care of throughout the day.



"It's a lot of work but it's the thing I know of and I love it," he said.



Redington runs dogs in the most challenging circumstances. But his latest challenge is dealing with running his truck, a 2000 GMC model diesel truck.



Redeington says diesel is the fuel of choice by mushers because of its efficiency and cost. The fuel's fumes are also safer for their dogs.



But he says he still has his share of problems.



"Last time the fuel injector pump went out it was $3,300," Redington said. "Five months before that the fuel injector pump went out and it would have cost us $4,200 but there was a warrantee on the pump. "



Russ Daly, who owns The Diesel Doctor in Wasilla, says business has increased about 50 percent recently. It's been good for him but, he says, it's not so good for the consumers.



"Altogether there are 11 vehicles waiting to get in to the shop," Daly said. "Almost all of them are with fuel injection problems. "



Car and truck dealers and automotive repair shops like The Diesel Doctor want consumers to know the culprit behind the diesel fuel problems is new emissions regulations.



"Because of the new emissions regulations they've taken the sulfur out," A5 Star Automotive owner Cara Cobb said. "It's damaging components in the diesel engine because of lack of lubrication. "



These shops say consumers with older-model trucks are not being informed of the issues.



They advise diesel owners to put additives in their fuel next time they fill up to keep engines lubricated. The diesel gas needs a dose with each fill up.



"When this doesn't get lubricated this injection pump itself, which injects the fuel to the injectors of your engine, this pump in here fails," Daly said.



Replacing the pump to meet new emissions standards is expensive but so is repairing it. The pump itself costs anywhere from $2,500 up to $3,500.



It's a simple case of supply and demand.



Symptoms include hard starts and hesitation. However, at times there is no warning when the fuel pump goes out.



Repair shops warn consumers to check with a diesel specialist or their own mechanic to determine what type of additive they should use in their vehicle.



Using the wrong additive could also cause damage.

as a guy who has worked in a refinery and now hauls ULSD every day, I say HORSE PUCKY! they've got contaminated fuels or something causing the problem
 
Gentlemen,

I'm with Big Easy on this one. I think many times ULSD gets blamed for the incompetence of others.

i agree that it may not be the reason that parts are failing right away. but i do agree that the new fuel will cause damage over time. with the amount of trucks with the same nasty fuel knock that i have. it has been a very common problem since the introduction of this newer fuel.
 
Maybe its fuel releated but the VP44 drop like flys anyway. Seems another way to get out of a warranty on a design issue.



Yes but what Mike saw was a dramatic and unusual rise in the frequency of them failing, coincidentally when the new fuel arrived. Yes it could be from clogged filters & dying lift pumps, so I bumped the thread up to see if he'd comment on what things have been like this winter.
 
MikeR says the VP44s are dying left and right again this winter, so I'd say that rules out the problems caused by the switchover of fuel types . . . looks like it's the winter variety of ULSD itself.
 
I am not sure what to think about this new fuel. It seems to have effected my mileage a little, to the negative. I have always used a fuel additive in my 2 trucks and always will year around, so hopefully I will avoid some of these problems.



One a side not my bother in law up here has an 01 Ram and has NEVER had his VP44 go out on him about 80K on the clock right now. He tows a trailer wiht it every day for his job. I told him to put fuel additive in it once this ULSD hit the pumps up here. I think he does it every now and then because he is not the mechanical type. He just drives the truck. So maybe there is some truth to the "horse pucky" idea.
 
Gentlemen- I continue to be puzzled as to why ULSD continues to get bashed? The company I work for owns and operates about 600 Cummins engines mostly ISMs and some ISLs. So I'm in a meeting with the local Cummins distributor service department manager and Cummins field service engineer. I ask "... have you heard how bad ULSD is for the Cummins fuel system and how it causes numerous failures and poor fuel economy. " Field service engineer says: "NO, what have you heard"? I said it appears that ULSD is causing numerous failures all over the U. S. to Cummins engines. Field engineer says:"This is the first I'm hearing of it". Somtime later after the meeting had broken up, I asked the service manager if Cummins has ever published a service bulletin or anything about the hazards of ULSD. His answer: "Not that I am aware of". So, why doesn't Cummins engineers and service people know about all these ULSD problems? WHY? Because it just ain't so!!



Respectfully,
 
I work for a JD dealer in Iowa and in the last year we ve replaced more pumps than in the last 5 yrs. All the pumps have shown abnormal wear for the hours. some as low as 2000 hrs. pump shop says low lubricity. biodiesel in about half of these tractors.
 
Just had to put my . 02 in. I had my VP replaced a few months ago at a diesel shop, (due to my own ignorance of running quadzilla wide open with stock fuel system and injectors) the mechanics there told me the same thing as Mopar4U, they have been replacing a lot of pumps. Their advice to me was to run Howells fuel treatment every few tanks. Also, we have never had any problems with out trucks gelling up, ever; last year mine gelled as well as my dads 99 and 03 this was before we started putting conditioner in periodically, hopefully will be ok this year, so far so good. Basically, I think ULSD stinks, for the mentioned reasons and my fuel mileage has took a hit, as well as other diesel truck owners I know, but what can you do...
 
The company I work for owns and operates about 600 Cummins engines mostly ISMs and some ISLs. . . .



The ISMs and ISLs probably have a more rugged fuel system than the VP44. If there's less than ideal fuel out there it would make sense the VP44s would be first to have issues. Time will tell how the other systems such as the P-pump will fare in the long run.
 
V. MacKenzie- I guess I'm not sure what is meant by "... less than ideal fuel our there... " . The point is Cummins service and engineering don't seem to know about this supposedly nationwide problem with ULSD. It would seem to me that the Cummins folks would have the best info on this subject.



Regards,
 
I stopped in at the local Dodge dealer to shoot the breeze the other day, and they had 2 third gen trucks that weren't running. They had fuel samples from the tanks, and they were nasty. It was real cloudy and murky, and that's at 60 degrees. A guy I know had fresh fuel out of his barrel (filled within the last couple weeks) that looked about the same. He's never had fuel like that in all the years he's farmed.
