I've got a new 08 6.7L with about 3500 miles on it. Up until now I've only ran ULSD in it, but in a month or two I wont be able to use the ULSD. I was wondering what kind of effects that will have on my truck. I don't have any mods done on it except a bullydog chip. Thanks.

I think its just LSD but not sure. I'm just 100% sure that its not ULSD. Am I best off to just take off the DPF and EGR systems off? Will that make it like the old 5.9, only a 6.7?

basically yes. the emissions are the biggest difference in the trucks, most parts are the same you just have more displacement.

I've heard it damages your injectors and/or causes more frequent regens... Remember your dpf is a FILTER.

You should probably dig more on the subject before you cause some expensive damage, and these 6.7's are much more of and engine than the 5.9's
even with the dpf :thumbsup

Congrats on the 6.7

The DPF has nothing to do with injectors. I only filters the exhaust.

The injectors are part of the emissions system on the 6.7.....they are not the same as the 5.9 and there are some concerns that the higher sulfur fuel can cause some long term effects on the injectors.
