Brother n' law says off road diesel is bad

[Kaliburz]

Still didn't find the go advanced.... but it's prob. just me. I looked up the manual codes for the smiles....

Well, as I said, Sea Foam states it's okay for diesel use. And I put 3 cans in my nurse tank, just in case, but my nurse tanks are 100 and 200gal. Granted, since my diesels are old, I also put in a enough PS to make up for the lube and for gelling (some of my diesel was purchased late October- wasn't sure if it was treated yet in my area.)

edit-
Okay, now I find the 'go advanced' button.... silly me.... was looking on the wrong page!


I try to keep everything topped of before winter, but that's pricey. Especially when you have to top of semi truck tanks.

Wow, that's a lot of pages in just 1 month, and no I did not read all but can't resist jumping in with a couple of things to add.
I have a 2007 emissions compliant dodge 3500 with a 6.7 Cummins and diesel particulate filter, there is a great deal of confusion and misinformation out there, I have followed this topic closely since I have a vested interest with 2 diesel trucks and 2 diesel tractors.
This is what I've learned:
* Only the 07 and later compliant vehicles require ULSD to prevent clogging the diesel particulate filter. (the DPF is a type of diesel catalytic converter that makes the vehicle meet the strict standards)
* ULSD is safe to use in all older engines, I know I'm skeptical to, but John Deere and Cummins, 2 of the largest diesel engine consumers in the world as well as the U.S. Govt. say no additives are needed when using the new fuel in older engines, except anti gel in extreme cold climates.
* My guess would be that what the original poster's BIL heard, was that off road or on road LSD was clogging up DPFs in newer equipment.
* Off road and on road LSD (500 PPM) are the same thing except for the tax and dye, of course the off road fuel is subject to more abusive conditions regarding storage and lack of rotating stock.
* some older equipment had trouble with filters getting clogged, not by anything in the new fuel but by the cleaning effects it had inside older tanks.
* For all those pumps that say they still have LSD 500ppm, more likely they actually have ULSD, they just can't change the label until they have cycled enough of the new fuel through the storage tanks to insure there is no LSD left in them, to protect the new vehicles emissions systems.

I'm on 5 different diesel truck forums and have heard nothing about what the original poster was concerned with and very little trouble related to ULSD except for maybe a slight decrease in HP and MPG's, there has however been no shortage of suspicion, wives tales and antidotes though, I myself remain unsure that's why I keep following these discussions.

Well, that's the 'good' thing about the internet, wives tales get spread at the speed of typing....... (some faster then others)

eek: But then again, do we want to trust industry AND govt. to give us the truth? It won't be them playing for repairs.... and by the time they do admit any errors/faults...... when will that be and how many $$$$ spent by consumers later..... ) Just doing my part to further the suspicion....

Happy New Year everyone..... keep safe tonight if ya venture out.....

So your saying the only real difference is taxed fuel vs. untaxed(or lower taxed) dyed fuel?

You hit the nail on the head dyed fuel is simply that, regular fuel (gas or diesel) with dye, same sulphur, everything. Dye is added so that when they dip your truck tank at the weigh scales and see dye, they smile and write you up a big ticket for road tax evasion

Trust John Deere...most of the time. Trust Washington almost never.

I don't know, but maybe your on to something there, after talking with some big wigs at the local Cummins/Onan dealer and them telling me no additives where needed, I found these engines out on their loading dock, some of them are brand new looking.
You can imagine these pictures caused quite a stir when I posted them on the Cummins forum.

 

[Kaliburz]

OUCH!

Is one the new 6.7's? The other looks like a 855 series (or N or what ever they call it now.....)

 

[KICK]

the one on top looks like a ISB with Common rail injection and rear gear train, if it matters.

since this thread is about fuel, how do you propose to compare rod failures with additive use or non use let alone drawing any type of conclusion based on aphotograph of a conrod hanging out the side of any engine. its probably lubrication related but that would be as far as I would go in drawing a conclusion.


somebody could have run those engines out of oil,its been known to happen. that old 855 might have a million miles on it and was being operated with low oil pressure. you just dont know.

I've also seen the EGR cooler leak enuf coolant into the cylinders of an ISB to hydrolock them and do the same thing, rod out the side.

actually pretty common for cummins to self destruct and throw something out the side, they use thinwall casting techniques in their more modern engine blocks.

seen more than one where the block was cut in two, up one side and down the other. like the 855 in the picture, broke the cam in two, pretty impressive when you consider how big the cam is in those engines, it must take who knows? pounds of force to snap the cam.

about the only thing you can assume by looking at those pictures is that cummins are not bulletproof.

I only posted the pictures for entertainment sake and not to imply anything other than jokingly starting/furthering a conspiracy theory. Man I wonder what it must sound like when one of those things blows up, when I posted these on my diesel truck sites it did cause a stir with the die hard Cummins fans of which I am one, there was about 10 blown engines out on their dock and 3 of them looked brand new, most of the guys thought they were run low or with out lube, I can't see how that could happen on a brand new motor. I'll tell you when word got back to the higher ups that I was taking pictures out back, I was asked to leave.
I still think Cummins 5.9L is the greatest motor ever put in a pick up, (not to start a war) I now have the 6.7, jurys still out on this, you should see the flame throwing going on in those truck forums, it could be quite entertaining at times.

A couple more pics just for conversations sake, the first one is the first I saw and even though I'm not a mechanic I was thinking to my self something is very wrong here. The 2nd one is another newer one with the pump still in place but the exact same damage as the other new one.

It generally doesn't sound like anything but a big bang.... sometimes drivers are obtuse and hear some loud knocking but keep on going, then you get the bang.... either way, its usually a big bang... aka..the big bang theory.... but remember, I'm just a mechanic, maybe the oil analysis guys in the white coats can give you a better technical description .


Yeah, cummins don't like it when you take pics of their stuff..

shoulda had you come by our engine shop, we got a bunch of cummins and detroits waiting their turn at the artificial reef program... tkae pics all you want, engnes are out of warranty.
