Okay I have a question and hopefully someone can answer me this one. What would happen if I don't put the recommended Ultra Low Sulfur 15 ppm diesel fuel on my 2008 F250 FX4. I live in El Paso Texas which is a border city of Mexico. The price for diesel here is averaging $4.30 a gallon. If I drive across the border, a 30 mile round trip, the cost of diesel is only $2.00 per gallon. However, the diesel in Mexico is not ultra low sulfur 15 ppm. Will this make my truck malfunction if I put diesel that is not the ultra low sulfur? Some people have said it does not matter.

I know its a big no-no as far as Ford is concerned. I'm sure you would clog up the DPF much faster with 500 ppm LSD vs 15 ppm ULSD. If I were you I'd find a station across the border that carried ULSD and fill your own tank plus the 100 gal. transfer tank you should bolt in to your bed... :nod:

There will be a time when every DPF will be clogged up and require cleaning or replacement.
By using LSD the DPF will need it sooner. It's going to be expensive.
The question is how long will it take. Let us know.
Not sure what it will do to the EGR system if anything but that's not going to be cheap either.
It will void the warranty. There are a lot of very expensive parts associated with the fuel system that will not be covered under warranty.
It is illegal with pretty stiff fines.
Use ULSD or move to Mexico.

Man, that's pretty harsh - even with the smiley! :nod:There will be a time when every DPF will be clogged up and require cleaning or replacement.

David is 100% correct on this :nod:There will be a time when every DPF will be clogged up and require cleaning or replacement.

CJ-4 in general. It was something I was told, I don't have the proof in front of me. I was told CJ-4 was not made to handle the extra sulfur. So when to much sulfur gets into the oil the acidic conditions may occur.

well cj-4 is the grade of oil and john deere has had that oil for a couple of years now and we have run lsd and it didnt hurt it in the tractors i run it in my pickup as well but i have an 03 7.3 so thats why i asked not trying tocall you out or anything just wondering

It's a true statement. Not that you can't use it but it shortens the oil life.
CJ-4 has a lower TBN, somewhere around 8 or 9 than CI-4 has at 11 or 12. What this means is lower ash (trace elements left over from burnt oil additives) content. This (the additives) is what helps control acid. If your manual says to use CJ-4 and LSD is approved fuel then the manufacturers recommended oil change interval is considering this and everything is good. Hopefully!!
With the 6.4L the recommended oil change interval would need to be lower to compensate for the deterioration of the oils properties (by contamination, depleted additives, high acidity, etc). You might in fact be better off using CI-4 and change it at shorter intervals if you must use LSD. The oils higher ash content will increase ash loading in the DPF and cause more regens and eventually more physical maintenance (cleaning or replacement) of it. A little extra calcium, zinc, and phosphorous to go with your extra sulfur. Too many factors to consider so it's always best to follow the owners manual.
CJ-4 is formulated to work with ULSD, that's a fact. By using ULSD less oil additives are required so CJ-4 low ash oil can be used and a DPF can be installed without excessive clogging.
You can't really tell anything about oil without regular oil samples on a diesel engine.
You can tell when the DPF is clogged though.
When it comes to oil loyalty runs pretty deep. You hear people talk about how good this oil is and such. The truth is the right oil is good oil. The wrong oil is bad oil. The people that formulate the oils would tell you that. They put a lot of money into getting it right.

I have a 07 model Kalmar container lifter road legal truck at work, which is equipped with a DPF and we ran LSD in it and within 2 months of it being brand new it was clogged bad and would hardly run... VERY EXPENSIVE FIX!!! They wouldn't let me keep the old DPF either, I was going to gut it and experiment! :thumb:
How's about this solution: He get's a dpf delete tune, delete pipe and changes his oil to CI4, changes his oil every 5000 miles, with those diesel prices plus the increased mpg isn't he going to be way ahead, even better than just a delete for us? Just a thought.

That should work.
As long as he realizes the loss of warranty and the legal issues.

Oils differ slightly in general but to be CJ-4 they all have to be low ash. Does not matter what kind it is.
Synthetic oil just lasts longer (maintains viscosity longer). It's not necessarily better oil other than that. In a diesel engine you cannot extend the oil life without doing oil samples. The lab will tell you when to change it. You may go 10,000 with regular oil on this engine or you may only get 5,000. With synthetic you may go 20,000 but you may not get more than 5,000. It depends on contamination and your oil filtering system.
The difference we see now with this new oil compared to past oil specs is that CJ-4 oils do not meet previous oil standards.
Before now when a higher rated oil came out it may in a sense have been better. That may no longer be true. CJ-4 is better for certain applications but not necessarilarly better for CI-4 rated or lower applications.
This is some specialized oil and I would not use it in something that does not require it.
Once again follow the owners manual on everything from your weed eater to your truck or Boeing 747.
Everyone is focused on the DPF here but I can guarantee you that the ULSD and CJ-4 is not only for the DPF. When they started putting EGR valves on diesel trucks they learned there was going to be a serious problem. The ULSD and CJ-4 is reguired for the EGR system. The EGR has more potential to harm the engine than the DPF.

6.0 in Latin America?
We are looking to drive to South America and back in our 2006, I'm wondering about the availablity of parts, repairs and if the diesel fuel will work. I plan on turning off the EGR and removing the CAT. Will we be stranded in Brazil for ever?

You resurrected a really old thread and you asked this question in a very odd place (a 6.0 question about South America parts/repair availability in the 6.4 section). Also, your question is really, really broad. You're driving around "South America". That's not specific enough and neither is Brazil really. It's the 5th largest country in the world. It's like 1/2 of the United States. I'd narrow down where you're going through a little more and then ask again... probably in a more general forum.
Sorry, I can't help you more than that.

The only thing that should be illegal is the government making us put emission on our trucks. Yeah I know the newer ones are better but it's still so hard on the engine. If I were you I would delete dpf and egr and run a different oil and run all the LSD you want. Don't worry about it there's more guys that are deleted here then arnt
