ULSD has anyone noticed anything yet?

Try getting sevral hundred thousand on gas engine exaust , wont happen



thats the problem on here too many uniformed people on here , oh well ,its all in fun

And too many know it alls that don't know it all, since gas engines produce alot more carbon monoxide and carbon dioxide in their exhaust, those items mixed with the water vapor make a very low pH chemical called carbonic acid which would explain why the gas engines eat exhausts.



By the way the exhaust on my 01 rotted of in less than 3 years, backend fell right out of the muffler. Think about what I've said and look at what you've seen. Do down pipes rot out? Or is it usually somewhere cooler where the gasses have had time to cool off like the back end of the exhaust? Yup



Oh and the exhaust on my 93 made it 6 years before the back of the muffler rotted off.



on edit:

By the way I went to look for some support of what I know and found This .

I'm not talking out of my butt, I work in a power plant and stack temperatures are critical when burning fuel oil. We actually have to increase exit temperatures and decrease efficiency to keep the back end of the boilers from rotting out due to water and sulfur creating sulfuric acid which happens in any combustion process where the fuel contains sulfur.

And there is a reason for that. I did some internet searching on the subject of ULSD a couple of weeks ago for a boating chat room. The same question was asked about the new fuel. Additionally boaters are also concerned about what happens to the new fuel as it sits in the tanks during winter storage .

There is not really a lot of good usefull information out there that I could find other that that they are adding lubricity to make it the same as it was.

It was not extremely reassuring to me. Especially since the change to ethanol last year in gasoline really wreaked havoc in the marine industry and has everybody still reelling from it's affects.

Everytime I read something it seems like someone discovers a new pitfall.

Oh well, let's just hang on and see what happens... it will be buyer beware.

I called and spoke with Cummins as I wanted to get more info on the subject. Their answer was the following... .



"The new fuel will be reverse compatible with the pre 07 Cummins engines, and there is no need to add any fuel enhancers to the diesel"



I asked about the fact that the fuel might shrink the injection pump seals, leaks etc, they asked me where I had done my research. Mentioned TDR, Diesel Power, etc. They said there will be no issues and that the aftermarket fuel treatments are basically all a big hoax. Nothing is needed in our motors. We will have no problems.



Also mentioned that if I wanted further info on the fuel, see Southwest Reasearch lab. They are a private lab that tests fuels. I have not gone to their site yet though.

Premature failure of fuel pumps was well documented when LSD was introduced in California many years back. Again, it was attributed to shrinkage of the seals. Perhaps the fellow at Cummins was too young to remember that fiasco. It seems that most of the failures occurred within the first six months use of the new fuel.

I dont want to seem like a big pain , but on the exaust issue ,



go check out the exaust on farm tractors and trucks , I have tractors and



farm trucks and know others that never get hot ,or warm thats not why the pipes rot off , its strickly just moisture setteling in the exaust pipes



and im willing to put money on it most rigs and tractors still have the same exaust they left the factory with .



More exaust systems go south just from sitting than actual running of the engines go do some more re search , I KNOW BETTER

 

[RSchwarzli]

Yeah, I kinda argued with the Cummins guy about this, and he said no to everything. Even told me that the engineers there said it was good to use.



My guess is if they were to admit the new fuel would cause a issue, they might be worried about the potential liability that it was "their fault the motors don't work with the new fuel". I have to say I was not very confident with his answer to the question either.



Also a thought, this new diesel reminds me of when gas went from leaded to unleaded. Would still work, but a few changes to the motor needed to be made.

Yep I remember that well. After a year or so I had to pull the head off my 292 six and have new valve seats put in because of that.



You might be right about the liability thing.

In reality this is part of the politicians clunker bill create new fuel so

the old junk is too exspensive to be on the road any more



hence they get there way one way or anouther except for some renegades that do are own thing

 

[Chris and Sam]

YUP!!

that would be all of us!!

 

[BSMiller]

Instead of running ULSD, why not use B5 or B20 to lubricate the injection pump?

 

[jimnance]

I'd like to run off road diesel which is still available and is not LSD. I'd even pay the tax, but I'm afraid uncle Sam wouldn't understand.

Thats right, it is not LSD, it is ULSD. All that makes off road diesel is the red dye added to it at the rack. Been covered here before, more then once. Why would you pay tax on something that is set up just for that reason, not having to pay road use tax on?

 

[jimnance]

While some fuel sold as off road is ULSD dyed red, there is still some fuel being sold that is not ULSD. If you've noticed, LSD, and to a greater extent ULSD lacks the distinct odor of old fashioned diesel. The place I purchase my off road diesel has the very distint odor of old fashioned diesel. It even says on the pump that the fuel contains MORE than 500 PPM of sulfur. I buy from a fairly big wholesaler and perhaps that is why it is still available.



Many ships with large diesel power plants must be started with conventional diesel before they can run the really low quality stuff that is almost bunker fuel in quality. Clearly, there must be refineries that are still producing distilate stocks that are not ULSD.

The bio-fuels simply are NOT available in lots of places - so no real choice!



If we had it here, I'd be happy to use it - especially with the substantial recent price increases in suitable fuel additives.



As far as the ULSD - can't comment on MPG until after our next trip in a few weeks - but the truck MIGHT be running slightly smoother - or else it's just my over active imagination...
