Opinions on the Dodge 6.7?

Do any of you have opinions on the Dodge 6.7?

Take off the emissions junk and its a great motor.

I got one a few months back and have put 15k on it so far. Haven't gotten into towing too much with it but have pulled close to 10k lbs more than once and it does good. Think it has a little more power than my duramax but is pretty close. This one is a short bed so it rides rougher. I also like the exhaust brake in this one better than in my chevy. Only complaint about the truck is dodge makes them not the easiest to service. The oil filter is a pain to get too and the fuel filter is also. They are on there tight from the factory so it takes some work to get them off. After that I don't put them on nearly as tight and it makes it a lot easier.

How is the fuel mileage on the 5.9 and the 5.7?

Not sure about those but on my 14 the computer says I am getting average 16.5

Walter

You mean 5.9 and 6.7?

The 5.9 is good for mid teens to 20 or so depending on gearing and transmission and driving habits. The 6.7 if deleted is good for about the same. Bigger tires and heavier foot will land you at the bottom of that spectrum. The 6.7 pre DEF so 2012 I think and before is good for 13-16 mpg empty. I have no experience with the 6.7 with DEF, but hear mid teens around 16-17 mpg or so.

Got one new in 2008. Ram 2500 long bed, 4 door, 4WD. At 30k put a delete kit on it. Empty it gets 19 mpg. Have pulled 20,000 pounds plus with it. Hit 100,000 miles last week. Never once has it been in the shop. It has been an absolutely outstanding truck. A real work horse, and it is surprisingly quick. I think I'll keep it for another hundred thousand.

Yes I meant 6.7 not 5.7. I currently drive a 2002 ford with the 7.3. I average 16-17mpg city and was getting 20mpg on hwy. My truck has not been chipped. I absolutely love the truck but cannot stand how temperamental it is when starting in the cold. I really like the dodges which is why I am asking this question.

My cousin had a '96 7.3. Was a great truck, it ran awesome, got good fuel mileage and he had a mild chip/tune on it. It would keep up with our '04 and '05 duramaxes pretty well. However like you said it was a cold natured SOB even with all the glow plugs replaced and functioning if it was below 40 or so degrees and you didn't have it plugged in... it wasn't going to start!

I also love the cummins. If you find a 5.9 in good shape I don't think you can go wrong and if you get a 6.7 and chop the DPF/EGR delete they are pretty great too. Getting rid of emissions stuff can be spendy though.

I love my 6.7. I have a 2011 crew cab, long bed, 4x4, 3.42 gears, with a standard. When it was stock, I got right at 15 mpg empty. I put a 3" suspension lift and 35s on it and dropped to 13 mpg empty. At around 50k miles I pulled all of the emissions out, put a programmer, exhaust, south bend clutch, and head studs in it and I'm back to 15-16 depending on how I drive. Sure I was shooting for better mgp, but it wasn't my main goal..

Have a 2014 2500 Mega 4x4 w/ 3k miles. Lifetime average is 18mpg. Over 20 on the Hwy @ 70+.

Love it.

Take the computer read out with a large grain of salt, its seldom right and I bet yours is wrong.

Got a 14' cummins reg cab 4x4...high way will see 20mpg (computer reads 23). So far so good at 25,000 miles!

The computer does lie a little but I have done the math at the pump and I can get over 20 mpg on the highway (65-70) in my 2014 4x4 6.7 no mods. I will admit though I'm still running the crappy factory street tires it came with. I'm sure my mileage will suffer when I get her some new shoes.

Best motor ever built is the 5.9 12 valve. Easy to work on no computers to screw with. Easy to modify for more horse power and gets fair mileage. 214,000 on my 97 12valve and I'd drive her across country in a second! Love not having a payment!

True, but what's it rated to pull 10k pounds max?

Exactly, it is a good solid old motor, but in todays market it competes with the ecoboost, not the 3/4 and 1 ton diesels.

I disagree somewhat, with factory cummins parts you can get 525hp at the flywheel. Not stock but not aftermarket either.

Sure and I can cram a couple pounds of boost down a 350 small block with a turbo or supercharger. I don't exactly see your point we are not talking about what you can mod out of one. You can plug a grogrammer into an ecoboost and do a lot of things.

Had one with 350k when I sold it.. Only work on it was rebuilt injectors at 300k. Guy that bought probably put another 200k on it

Turbo charging a 350 (I assume you mean a GM small block) compared to buying stock over the counter parts from your local cummins distributor. The modification of getting 525 flywheel HP out of a cummins 5.9 B series can be done without "performance" parts and with no internal changes to the injector pump..


Refresh my memory on this since you seam to know a lot about mechanics but, I don't recall ford selling a programmer for a ecoboost and I don't recall GM ever selling a turbo charged 350 in a non performance application.

Lefty, no ones really arguing with you.

Cummins = good.

Old dodge truck = not so great.

I tend to like the older dodges, in fact I have a 2000 dodge 2500 QCLB 5.9 ltr 4x4 with 264,000 miles on it. It has it's quirks but I drive it more than I drive my 2012 ford f350

I put 120k on my 08 6.7. 100k of that was deleted. It had steering and front axle problems and the trans was weak. That was the last of over a dozen Dodge Cummins that I bought. Really glad I switched to Ford in 2012, love this truck. I still have a 2002 Cummins 4x4 with 280k that is flat [censored] worn out but it still runs good when it's not having dead pedal issues, or having to take the front driveshaft out for its 75th rebuild. The truck needs to be replaced but the Cummins is good. Can't say the same for the 04 and 06 Dodges I had, the 04 was pretty good except death wobble, the 06 was an absolute pile of crap, front end, rear end, a/c, fan clutch lights sensors going out and everything rattled apart.

That's funny and the goofiest thing I have ever heard, I use to haul 20k pounds plus of pipe, purlin, cows and hay with a one ton dulley. Today's market is about dealing with EPA, ultra low sulphur diesel and marketing. Pulling is factious number any way. It's all about how you set the trailer up and how much of the weight goes over the rear axle and how the tranny is made and geared to handle it.

I'm starting to wonder if you ever really used a truck.

Compete with the Eco boost...lol only if you don't have to go over 10miles loaded. Loved to see an Eco with 200k plus miles of pulling 15k pounds plus on it.

I was just going to leave the poor kid alone. Its obvious he doesn't have a clue..

My 5.9 won't even start unless I have 9,999 lbs or less on the hitch

Bobo, you were pulling 20k with a 12v Cummins 1 ton dually?

Im talking performance not longevity. The 12 valves un-modified are not performance oriented motors. They are not even in the same leage as modern diesels in power output. Ive put a couple miles on a 12 valve sure they run and they pull, but they don't have near the pep of the newer motors! You know that and you could argue the other side of it too.

Yelp. Every other day.

Enquiring minds want to know... what transmission rear end and how far and fast did you pull it Is this like the guy with the chevy v-6 standard that pulled his gooseneck stock trailer 2 miles to the auction?

Red.. Pep wise your right. I will probably go to my grave still saying the old 12valve was the best deisel ever built, none of the new deisels can take a tenth of the abuse including old 12 HO. Ask me about my last three lol!! Tuned to high means go boom.

Why I agrue with you about the Eco in a 3/4 so much. I'd rather pull 20k with the 12v then my 6.7, 6.4 or 6.0

Lol, that old man was something else.

read my post earlier on miles. Owned a fencing/building supply company. Hauled pipe, and purlin all over the country durning the week for free stall barns, and hauled hay and cattle on the weekends. Old blue, think was a 93 model. Tranny was just the stock manual with the granny gear. Don't think I ever had the truck over 80mph unloaded.

Its getting kinda tuff to go out and buy a 12-v though. If i could by a new one for what they used to cost i surely would!

I've got four still running irrigation motors in the panhandle.

Wow, my gen2 doesn't even like to pull 6k. It's does ok on the bottom end but get it up to 50 and talk about flat line! My uncle used to pull a triple axle camper with it (I bought it from him) so maybe it's just plum work out now... My 2012 6.7 ford pulls pretty decent but my 2005 cummins pulled like a train.

You should get that looked at, mine pulls 14k all day long with almost 300k miles and 35's

2010 6.7 2500 4x4 mega cab. deleted everything. mini-maxx stock turbo & 4"exhaust stock injection timing etc...
33.5x17"
16-18 driving like I should/ 10-11 pulling 15k @ 75-80mph
It can pull beyond the limits of the truck/ trans and diff. They will make crazy power/

After working for a dodge dealership I find some of these 6.7 fuel mileages a lil over the top most of our guys coming in raised hell about getting 11 or so miles to the gallon. On the other hand dodge claimed with programming they could take the 6.7 high output to 1000 hp. Just what the engineers claimed

It takes a lot more than just programming to get 1000 hp out of a 6.7 cummins. You can only push so much fuel and air through stock components, and the bottom end will grenade around 850-900, and that's on the high side. Your average is closer to the 750 hp range on the bottom end. When my 2011 is all said and done, I'm shooting for around 650 so I wont have to go internal, yet still stay reliable.

I am always on the look out for a pre 94 dodge with the 5.9. Used to drive one for work and it had the torque flite automatic. I would of rather had a standard but it did the job. When I left she was at 500k+ and we never did anything to her. She was always hooked up to a gooseneck and no less than 10k pounds. Not a speed demon but slow and steady won the race. I have since owned 3 24valve cummins and my favorite was the 04 CC 4x4 LWB with a manual. Got 20+ and she had plenty of pedal. My 2012 6.7 was nice but checking fence was not her cup of tea and I was hesitant to pull the emmission components due to warranty. Best one I have owned over all was my 2012 F250 CC 4x4 with the 6.7 power stroke. That truck was a beast.

I had a 2003 5.9L with the manual 6 speed tranny that pulled like a mule. For the guys complaining about the newer trucks not towing as good its probably because you went from a manual to a automatic with a higher gear ratio. Try using the (if you have the option)shift button in manual mode on your automatic when your towing to keep your RPM's up when your trying to get to a cruising speed. I have the 6.7l ford now deleted all emissions components and I'm very satisfied with the towing performance. I tow a 30+5' dovetail gooseneck loaded with a 90hp tractor and it handles it well.

I have a 2011 6.7. Deleted it, added a Smarty JR67 to it and a S&B Intake. I was getting around 21-22 on the hwy and 17-18 in town with 265 tires. I put 295 M/T on it and I am around 17 on the hwy and 15 in town. The truck will run. I keep my foot out of it most of the time. It is also a good looking truck. I will say that as soon as these tire wear out, I am prolly going back to 265s since this is my daily driver. I will prolly stay with the M/Ts though. If I can find a little gas rig to drive daily, then I will put 20" wheels with 35x12.5-20R in it. I am still at least a year away from that though.

I'm looking at a 15 ram 2500 cummins 4x4. From what I've been told and seen, they are seeing high teens empty. For me there is no reason to delete, as warranty is worth a lot more. Once warranty is out I'll evaluate that option.

2008-2012 Didn't use urea and only had a DPF. Empty fuel mileage of about 13-14 was very common. The newer ones are better.

My 09 mega cab gets around 17... id keep it over a new one if it came to it... she has 235k on her and is a daily driver

Still plain ole factory tuning *

bout what I got out of mine also, but I wasn't the norm.

I get crappy mileage out of both my Dodges, though my '99 8.0L get's a heck of a lot better gas mileage than my 2004 8.3L.

2008 4x4 deleted, with the 295/70/17 it has reached 19 mpg. Sitting on 103,000 miles and it has not spent the night (or day) in the shop. December I brought 20k worth of 32' trailer loaded with I-beam from Maddil, OK to Wolfe City, TX. 65-70 mph down 377 and across 82.

I still don't know what that truck WON'T pull. And it's the fastest truck I've ever owned. Wish the back cab was a bit deeper, but not enough to go buy a new truck. When I bought it, I figured 10 years, or 200,000 miles then I'll think about another truck. 10 years is going to happen first, and I don't want into another payment. Guess I've got 97,000 miles to go.

2012 6 7 dually 4x4 pre def model 6 speed manual transmission all factory, i get 11.5 mpg pulling 40' gooseneck trailer and 14.5 mpg without. No problems yet.

2007 Dodge Dually Automatic 6.7 deleted since 60K miles and currently has 250K miles. Has not been in a shop for anything.

Great truck.
