bought a new 6.7 and was wondering how you can telll what job build it is if it isnt on the sticker? and can anyone tell me how much fuel you burn off when the def goes off, thanks

 

If the truck was built before August 20th or thereabouts, it is a Job 1. IIRC, Job 2 changes were added incrementally into 2011. I also remember November as a big month for Job 2 changes.

I can not answer your DEF question as I am unsure of what you are asking. Sorry

Regards

 

Where did you find this info out? Is it somewhere on the truck or is this info from Ford.

 

Unfortunately, I had to depend on my recollection of the information that was posted here previously. The details were removed from the thread without explanation. The information is accurate but the dates could be a few days off either way.

Regards

 

Could you possibly just look at the seats? I was under the impression that is when they went to the solid color seats

 

I think technically Job 2 is November 1, 2010 (Job #2)
and the 400/800 reflash is a post Job 1 update, starting Sept 7 as I recall.

typically the 'job' numbers identify a significant build process change.
(seats, heated rear window, headrest monitors...)

just like on 08's.. the backup camera option didn't come til job 2.
(I have an 08 job 1)

...and Sam said it better than I did. I found the whole Job1/Job2 transition to be somewhat confusing. Even when the now deleted General Info page was up, there were some gray areas.

I just had my truck in for its first cow **** fill up, and i notice on the back axile there was a sticker that said job 1. my truck was built in nov of 10.

 

ah the joy.. there is the plan, and what actually happens..
and sometimes those two are the same!.. only sometimes..!

i mean i hear about the def burning off diesel fuel when it goes into def cycle, how long does it take for it to complete? i heard that the rpms go way hight and that it will use up to a 1/4 of tank of fuel to complete that cycle, or is this hog wash ? thanks for your imput

 

Haven't notice my RPMS go up.... 1/4 tank of fuel.... Sounds like crap to me lol

 

a guy who works with me said his brother has a 08 diesel, and that it uses a 1/4 of tank of fuel when it regens, so i didnt know if the new ones did the same, im sorry for all these stupid questions, but i never had a diesel or knew anyone that did, so sorry again

 

I had an 08.... Didn't use a 1/4 tank of fuel...

 

There are no stupid questions. OK, maybe that's not quite true. There are no stupid questions here.

Re-gen on the 6.7 diesel is far more efficient than it is on the 6.4 diesel. I also have a friend with an '08 (or maybe it's an '09--now I can't remember).

Anyway, his MPG goes in the toilet during re-gen, dropping on the order of 6 to 8 MPG. It borders on the ridiculous IMO.

My '11 loses at most 1 MPG during re-gen, and usually not even that from the times I've paid attention to it.

I believe the 6.7 will also go through fewer re-gen cycles than the 6.4 does.

Hope that answers your question.

1/4 tank of fuel for a regen; I don't see it.
A 2008 short bed had a 30.5 GAL tank.
That would mean around 7.6 GAL used for REGEN.
That's a lot of fuel.

On my 6.7L, I have 1 regen per tank and that causes 1 MPG loss for that tank.
