The newer truck will still burn upto 5 gallons of fuel per regeneration just like the pre DEF trucks did. What the DEF does is lower the levels of NOx coming out of the tail pipe during a regen.

I've had this 2013 with DEF for 28,000 miles and it will be 2 yrs old 9th of May...and no, the truck WILL NOT burn up to 5 gallons of fuel per regeneration...The new/newer one's may possibly burn a gallon, (that's even doubtful)...but NO WAY will the newer trucks with DEF use 5 gallons of fuel per regen...I've not seen that in my experience...In Fact, having owned an 07.5 Chevy with DPF, a 2010 Ram and a 2012 Ram, both with just DPF, none of those EVER used 5 gallons of fuel for a regeneration.. The "instantaneous MPG dropped terribly when in a regeneration, that's why it was so easy to tell one was in a regen...it was kind of obvious. Some say their truck has never had one, but yes it has...it's just that technology has come so far that one can hardly tell it now, if at all...and if one burned 5 gallons of diesel for ONE regen...it would show up terribly on ones mpg...

Do the research on what you stated....it's not true for the new/newer trucks with DEF..one will not burn 5 gallons of fuel every time they have one.

I said UP TO 5 gallons not that it would burn that every time. That is as per Cummins themselves for who I'm a trained tech

Never saw anywhere that "Cummins" themselves state that with a regen the truck could use "UP" to 5 gallons per regen...that's ludicrous...I don't care who you were trained by...I did the research and have yet to see where a diesel, be it Duramax, Powerstroke or Cummins with DEF would burn "up to 5 gallons" a regen...Sorry not buying it...I've NEVER seen anywhere NEAR that...not even before DEF, when I had DPF only.

might want to take a refresher course on that one section....

I would give you the site where it shows how much fuel and DEF is used per each type of regen but you have to be a Cummins tech and have a login to view it. I just finished the update course a few weeks ago so I would guess I have the latest info but if you have newer feel free to provide it. If I can find a way to get the info so that you don't need a login I will post it for you.

Well,, I'm not a tech...just a dumb old Engineer who is not using ANY books, updated or not...just based on almost 2years of experience with this truck and 28,000 miles....I'm OCD when it comes to hand calculating MPG EVERY tank of fuel I get, and same with DEF refills. I would think I would have noticed "up to 5 gallons" of diesel fuel just "disappearing due to a re-gen...Thanks for the information....but experience speaks volumes. I'm just doubting that "up to 5 gallons of fuel is being used with every re-gen.....

Keep your log-in, I've done some searches since we started sparring back and forth with this and also posed to Techs on the Cummins forum....but again...not buying it.

With only 28000 on your truck you wouldn't be using 5 gallon every regen. It can be up to 5 gallons and as the DPF fills up with soot it will take more and more fuel to try and clean it out. I not saying that it will use that much every time but it could. Take it into the dealer for a regen and I have seen them use half a tank of fuel to do a regen.
I didn't see your post on the Cummins Forum but I will be sure to answer it there too as I'm one of the techs from there.

You have ZERO clue what you're talking about.. Why would I take the truck into the dealer to do a regen????? When the vehicle shows DPF full, you'll go into an active regeneration and you are told to drive until message goes away...at that point you "MAY" use a couple of gallons of fuel, but I've owned DPF equipped trucks since middle of 2007 .(07.5 Chevy), and two Dodges and NEVER got DPF full, though, DPF trucks without DEF use more fuel when in regeneration...With DEF, "most" of the regens, under normal driving conditions are passive regens and yes, you'll use a little more fuel, but most don't even know they've had a regen...

Yeah, I'm NC Hauler on the 2013+ Forum and the thread is there asking for techs to give information on fuel usage during regens...no one bought into what you've said....when you state, "UP TO 5 GALLONS may be used"...you lost a PILE of credibility..I've NEVER seen that. IF I got 10 mpg, and was running 60 mph, I used 5 gallons and have to drive 50 miles to get out of a re-gen????? No, I didn't even have to go that route when I had DPF only.

Yeah, I know, you stated you "might" use UP TO 5 gallons....sorry...I've not seen it...

dapperdan, sorry buddy, I really didn't mean to hijack your thread...

ON EDIT: It's the "cumminsforum"...4th gen, 13+ and up...

So I guess I am mistaken as to the latest specs for Dodge. I was going off Cummins specs for their engines which would be in none dodge vehicles. From the dodge DealerConnect site which is where dodge techs get their info. And Dodge calls it a Desoot not a regen but is the same thing.
DeSoot procedure will consume approximately three gallons of fuel. Ensure that the tank has at least three gallons fuel

There are no "latest specs" for Dodge trucks because they don't build them anymore. There hasn't been a Dodge truck sold since 2009. In 2010 Ram was spun off from Dodge and they have been Ram trucks ever since.
