As I filled up today, I noticed the seal on the pump stating that this is the ultra low sulphur diesel fuel. Interertingly enough, it stated that model year 2007 should not use this fuel. What happens in August/September when the 07's start rolling out? I started to read on this and found this link:

Now, for you fuel experts out there, are the refineries putting anything in the fuel to assist in lubricating the internals? If not, we may be seeing some problems down the road. I have always used Stanadyn in my fillups, but it looks like this will be a requirement for al of us.

Just putting this out there, it caught my eye and am glad that I always conditioned the fuel.

 

I believe on the newer trucks synthetic seals are the norm, so biodiesel or ULSD won't be an issue.

Bosch components used on the dodge cummins switched from nitril rubber type gaskets to viton type gaskets on the vp44 and newer injection pumps. These pumps should not be affected by ULSD. Not sure about earlier produced injection pumps.

That article is interesting I stopped reading it before I got to the end of the first paragraph right after I read australia and rubber components.

 

Are you sure you read the sticker correct, 2007 model vehicles is what the ULSD is designed for.

Yes, read this http://www.chevron.com/products/prod...sel/ulsd.shtml

 

Yep, the seal stated not to be used for model year 2007 vehicles. I'll take a pic of it and post. I was wondering if that is true, how in the heck will them guys find pumps or, will things change down the road. Like I said, it really caught my eye. Here is a link of what I saw, it is the second label listed:

great link bekim! THX

 

If it is the second label down, notice that it is the "Low Sulfur" diesel (500 ppm) and should not be used in 2007 models because the top label "Ultra-Low Sulfur" diesel (15ppm) is what is to be used in the 2007's. That station has evidently not switched to the new diesel fuel yet ("Ultra-Low").

 

As CTD trucks are shipped new from the factory with a partial load of B-5 biodiesel/dinodiesel mix in their tank I would suggest simply adding biodiesel to your tank occasionally to address the low sulpher fuel issue and then at least you won't have to worry about it. Long as your mixture is B-20 or less, there've been no issues in CTD trucks like there've been running the B-99 mixes and gasket deterioration etc. Even then that's not an overnight process as it would take tank upon tank, week after week of the straight stuff before those issues would most likely even show themselves. Biodiesel can't be beat for adding and otherwise addressing luricity shortages in our modern day #2 diesel fuel. Even in as low as a B-2 mixture. Chuck

 

Got to wonder if the real reason Chrysler is using B5 is so the new engines run quieter, which makes them easier to sell.

The refiners are in almost total agreement that the best way to address lubricity problems with the new ULSD fuel would be to make B2 the national standard.
The wall they are running into is that the aviation industry, which uses the majority of diesel in this country, doesn't want any percentage of BD in their fuel to the point they are concerned about BD residue in the pipelines.
The alternative is to truck and add the BD closer to the point of sale. For me this requires a great amount of trust. If you're not for sure using BD I think it will be an excellent idea to use diesel additive until things are ironed out.

I thought the new engines were quiet anyway. That's all I ever hear from a new CTD owner is that "this generation of engines is the quietest yet". Add in the less than desirable mileage per gallon and that high payment on that new truck and....well, they can have their "quiet" new truck.
