Diesel formula has changed. The new diesel will have almost no sulfur compared to the previous formula.

The new motors will be set up for the newer stuff and the old stuff can apparently cause problems. I don't have a diesel, so I haven't read up on it.

Ultra Low Sulfur Diesel

So is the Duramax gone? or just modified? And is this going to make all older diesel owners have to buy a new truck or a conversion kit?

Here's some info on the new fuel.

yeah, seen a few articles about the new fuels in this light truck magazine i get at work and it's been an interesting read. I believe there is also going to be some new emmissions rules set in place on diesels, starting with teh 08 production year, but i could be wrong

Wait to you see how many large can looking things are going to be on new diesels after 08, "particulate filters" to ensure nothing gets out of the tailpipe. So where does it go? Rerouted back to the engine, of course. Great. The 07 Cummins has some of this crap on it already. If any of you guys have seen the write up in some of the recent mags (can't remember which one but there have been several) you can see a cut away pic of the new cummins exhaust, damn is it huge. I am not sure what is going to happen to the aftermarket exhaust industry in a few years. You might not be able to take those damn stock pipes off and have the truck run .

This better not effect dyed ag diesel. The lubrication properties are next to none as it is with the current diesel. The lack of lubricant is eating up injection pumps and injectors like no other on these old tractors.

for all the older diesels you will have to purchase a fuel additive to assist in the lubrication. easiest alternative is to run biodiesel or veggy oil though.

Are you freakin kiddin me. This is not going to go over well at all.

the new diesel is supposed to actually have a better lubricity because of the way it's manufactured. This means it should be fully compatible with all old trucks....or so I've read.

thats the opposite of what i've heard about the lubrication ability of the new fuel, but we wont know for certain until they have the formula ready. older diesel engines were built to run the old diesel (duh) that gets most of its lubrication from the sulfer in the fuel, the current fuel has much lower sulfer percentages, so your lubrication with #2 diesel is much more limited than it used to be, but a hell of a lot cleaner. the #2 fuel to come in the near future is supposed to have 0% sulfer, so the cleanest petroleum diesel ever, but as far as i have heard there is no lubrication additive in the soon to come fuel.

if our brilliant US government was smart and wanted to reduce our dependance on the middle east (and clean up the environment), they would begin taking all those left over crops, and allowing our farmers to produce more of at their max (instead of the usual 50-80%) we could easily produce enough diesel fuel to power our vehicles/boats/everything else that is diesel.

There is nothing to worry about with this new diesel (ULSD). Older trucks will run fine on it. They are putting lubricity addatives in the new fuel at the refinery, it will actually have higher lubricity than the current stuff. Allthough I would still reccomend running a good addative in any diesel regardless of fuel type. By the time the new trucks, that require the new fuel, are on the road the only diesel you will be able to buy will be the new ULSD.

While I totally agree with you we should be producing as much bio-diesel as we can, we do not have the capacity to replace all the diesel fuel we use in the US with traditionaly grown crops. We need to look more towards making the fuel from biomass and other plants. I think in europe they succesfully made biodiesel from algae grown in sewage treatment ponds.

I live in central PA and they are currently building the largest bio-diesel refinery in the US here, very exciting stuff.
