08 dodge 2500 diesel fuel mpg $

[jaxnjil]

wasn't looking but had a friend call me about a 08 ram 2500 heavy duty. 4x4 with 6.7 diesel and 6 speed auto.

S L T trim package. 18000 hi way miles. $30000

seemed like a really good deal to me and i could replace my 99 gmc serra with 173000. the little gmc is in really good shape and wasn't thinking about getting rid of it. in fact was going to drag the ray to mead with it in a couple of weeks.

was looking at the dodge and got to thinking as much as jill and i drag the ray, {7500 lb} might be worth a look as the gmc is getting a little age on it.


does any on here on the forum have one of these 6.7's and if you do what kind of fuel milage do you get.

was talking to gmc dealer and he told me to stay away from the newer-late 07 and up cummins. he told me they use some kind of a filter between the exhaust manifold and catalytic converter and the best fuel milage you can get on the hi-way empty is 12 to 15 miles per gallon
i didn't eve know there was a diesel pu that used a cat c.


any way if you can help clear this milage question for me i would appreciate it

Re: 08 dodge 2500 diesel fuel mpg $

While I DO NOT know what mileage the Dodges get, I will say that the 2008 model year emissions include Particulate Traps (this is on ALL diesels). They do seem to affect fuel mileage, as my dad 2008 Chevy 3500 doesn't get as good of fuel mileage as his 2003 GMC 3500. It's better than the numbers you list, but not as good as the pre 2008 trucks.

till; i was surprise i'v been out of feild service for awhile now. my last service truck was a 00 or 99 3500 H D ford power stroke and that thing got 22 to 24 mpg all day loaded down and running hard.

Re: 08 dodge 2500 diesel fuel mpg $

i get around 20 to 25 depending on what im doing. i hate this truck in every sense of the word.
but my personal is a 02 f250 its a ton more comfy. i will admit to being vary impressed with the Cummings great motor drives nice mines totally loaded for a 2 door. i do beat it really bad this truck spends 90% of its life in a ditch. and its held up really well. did i mention i don't like this truck.

Re: 08 dodge 2500 diesel fuel mpg $

One of my really good friends has a 08 Cummins 1 ton (dually). He's pretty disappointed in it, he said it won't break 12 mpg city/highway mix (probably more city than highway). He traded in an 02 Cummins that got 17.

It will pull a house down the road if you can afford to feed it.

Re: 08 dodge 2500 diesel fuel mpg $

I owned one last year, It drove great,exhaust brake, and it does have a filter on exhaust, Owned previous Dodges with cummins, got better mileage out of the older ones, I got 19 empty on highway at 70 mph, and about 15 around home, rural area , Only pulled a few things ,but not long enough to figure mileage. They had a few problems with sensors , and when it re-generated it burnt more fuel. Diesel is 30 - 40 cents more a gallon, it holds 12 quarts of oil, the fuel filters are a little exp.. But the truck would pull nice, new 6 speed shifted more like a gas truck, like the ex. brake going down hills. My old dodge's with cummins got 20-22 highway 17 around here. Anything else i can help with , feel free to ask, Tim

Re: 08 dodge 2500 diesel fuel mpg $

I am not positive, but I believe my dad's 08 Duramax get about 18.5 highway. His 03 Duramaxes (he had both a 2500 Chevy and a 3500 GMC) got closer to 21. And the 08 has the 6sp Allison, where the 03s had only 5sp Allisons. You do the math!

Re: 08 dodge 2500 diesel fuel mpg $

our parent company has a 08 ford 350 and it gets 8mpg empty on the freeway our dodges get in the 20s both of them. and i thought they all have the filters on the exhaust now.
sucks off road though i get stuck 3 or 5 times a day

Re: 08 dodge 2500 diesel fuel mpg $

I am a huge Cummins fan, and own a 24 valve at the moment. No way I'd own a 6.7 with the emmisions crap. The DPF causes issues, and I have seen a ton need new turbos as well. I used to work for a Dodge dealership, and the mileage on the new ones is terrible.

My old 24 valve is seriously hopped up(big power), and still get's 18-19 daily driving.

Re: 08 dodge 2500 diesel fuel mpg $

I own an 08 3500 4X4, quad cab, LB, SRW, 3.73, 6.7, auto @ 20,000 miles.
I love the truck and wouldn't go back to a 5.9. The best mileage has been 17.8 @ 70mph empty. The worst has been 10.5 towing my 22' travel trailer with my quad in the bed in the mountains. These new diesels work great for those that pay attention to RPM's and don't lug them. They aren't good short mileage commuters and certainly not idiot proof.
If you have something heavy to tow and room to run, the 6.7 with its built in exhaust brake is fun to drive up any mountain and down the other side, loaded or empty

LOL, idiot proof You enjoy replacing your turbo, AND hand calculate your mileage, the overheads are a guess at best.

I have personally SEEN at least 10 trucks that needed turbos, and many more with DPF issues.
I have a lot of Cummins experience, and love them, and like I said, no way in HELL I'd recommend a 6.7 to a friend, and neither will the service guys at the dealership I worked at.

I'm not trying to be mean here, but to say they aren't "idiot proof" seemed antagonistic to me. Maybe I'm wrong. I'd say an 08' is indeed idiot proof compared to my 98. Except for when they need their turbos replaced, or whatever other issues they come with.

Best of luck with yours.

Re: 08 dodge 2500 diesel fuel mpg $

BTW, ALL Cummins in the trucks most efficient RPMs are 2150, you will get your best MPG's at that RPM.

Looks like the 08's have less problems than the 07.5's, but they still are in the shop a lot.

Check out this article on the 6.7's, MANY people have problems sadly.

http://www.mycarlady.com/2007-2008-cummins-67l-gives-owners/

?The Dodge Ram 2500-3500 6.7l Cummin?s ain?t your father?s diesel.? as the saying goes in garages and forums around the country. Thanks to tremendous pressure from the EPA, all US diesel truck manufacturer?s had to redesign their engines to meet new Clean Air Act standards that included burning Ultra Low Sulfur Fuel. The result was a mis-mash of clever technology that recaptured the exhaust, trapped the nasty carbons and labored the task of keeping the torque/power. In the case of Dodge, this new system also boasted a horsepower gain.

However, the results have been fraught with consumer complaints, many the result of poorly communicated driving, servicing and fuel economy expectations from the salespeople pushing the reincarnation of the Cummins. Those familiar with the previous Cummins engines, should have had special lessons on the new 6.7 Cummins. Posters to CumminsForum.com are quick to regale whose truck is better, however, they also offer some suggestions for why the check engine light pops on in less than 100 miles and why the fuel economy is so poor even at 10,000 miles. ?The bad fuel economy comes from the dpf filter anytime fuel gets burned twice that will lead to (poor)fuel mileage. All diesel blow soot stock. It is slight and u dont see it but if u drive a stock diesel like grandma for a month and all the sudden punch it there will be alot of black smoke. The main reason DPF filters are clogging up is people are not getting on them once in awhile If they would open them up a little there wouldn?t be so many problems.? offers Duramaxin14.

Early 2007 releases had to have EGR Valves, Cat, DPF and Turbo?s switched out and computers -reflashed, which seems to have resolved the initial spate of complaints. 2008 Ram owners have had very few complaints, so it appears the computer software upgrades and modifications to the DPF have helped quiet the storm. The oil is blacker than previous models/years and some folks report the vehicle having random fits of tetesterone: a Turbodieselregister poster offered this comment; ?I had no clue as to what kind of power was lurking there until the other day, I felt a surge and just sort of wanted to feel it out and went ahead and floored it ?..holy smokes it spun the tires? then again as it shifted into second??no spin in third but Oh my god this thing was like a rocket?. ?

The power of the Cummins 6.7L is what brings most buyers to Dodge in the first place. The history of trouble-free engines (one-third less moving parts) running 350k+ miles is what keeps Cummin?s owners coming back. (And in 2008 a Lifetime/Unlimited Mileage warranty and 0% )

Here are a few suggestions offered by readers, Cummin?s owners and Dodge Technologist?s themselves?

1. Drive it hard, often. Get down on the pedal and stay there, DAILY. Push the power curve on and off-load.

2. Don?t let it sit idling. You aren?t waiting for the glow-plug anymore. Idling is bad for these buggars.

3. Let the oil changes go a bit longer. Lubrication of the engine is huge, and the new fuels aren?t helping.

4. Change your fuel filter more often. The factory suggests 10k intervals but those in the know are doing their trucks every 7-8k as preventative medicine. A little expense that could save you BIG later.

5. Watch the quality of the fuel product you are buying. Make note of any changes in performance from one tank to the next, station to station. Not all fuel vendors are created equal.

I will be interviewing a 20yr. Cummins veteran and will share with you more on the 6.7l Cummin?s story.

Not to harp, but the original poster asked for factual opinions.

Here's a link to a class action lawsuit involving the 2007-2010 6.7s

Not to be antagonistic, but are you working at Ford or GM now
Anyway, my mileage is hand calculated. I frequent the Cummins Forums too. I also chat with the diesel mechanics at my dealer, to keep abreast of problems they are seeing.
My friends with 6.7's are just as happy as I am.
Of course, the trucks aren't without problems, neither are Ford or GM. That said, it appears that most serious problems can be traced right back to an owner, who putts around town lugging the engine, and doesn't use or even understand the exhaust brake. The other kind of owner (being nice) adds this, and disconnects that without a clue as to what they are doing. The most humorous to me are the guys that actually do get their trucks to run with serious horsepower and immediately tear something up. These owners then start un-doing this and re-installing that in an effort to claim warranty, which of course would be fraud.
I won't address the canned lawsuit thing, distasteful.
Nice chatting with you and thanks for the well wishes

Pretty consistent comparing my dad's 08 to my 01. He sold me his 01 and now complains about the mileage of his 08.

To the OP. 7,500 is about where the diesel starts to make a difference. But I would be leery of the 6.7, or any of the newer ones, as I think they still have a year or two to work some emissions kinks out. But if you can find a bit older, it will be a world of difference from what you have now. I love my 01 Duramax and would recommend it or one like it. If you drive an auto, then GM is the only way to go for the early 2000's diesels. Ford and Dodge did not have a tranny like the Allison. If you drive a manual, I'd go with either the Ford 7.3 or the Cummins 5.9. Stay away from the Ford 6.0l in any setup.

Ford or GM, no way! We bought our own business. I love the Cummins, and my truck has been entered in truck pulls and drag races, plus it tows all of my toys and junk.

Believe me, we saw a ton of warranty fraud type customers when I did work at the Dodge dealer.

I don't think the lawsuit is distasteful, Chrysler is very tough to deal with on this sort of thing.

I'm glad we can agree to disagree, and nothing would make me happier than to hear you get 300K trouble free miles.

I hate to break it to you, the Allison is NOT the big truck Allison, and they go up with the same frequency as a newer Dodge trans. I don't know about the Fords. I know this from talking to local service departments when I was in the business, and they have just as many trans at a GM dealership parts dept as do the Dodge dealers, and the failure rate is pretty much the same, especially amongst those that really use their trucks.


That being said, I got my 47re to last to just around 100K, with big power. I know have a full billet, competition trans in my truck, handles my 550/1100 at the wheels with no sweat.

I agree with the avoid the Cummins 6.7 and the Ford 6.0 as well.

Re: 08 dodge 2500 diesel fuel mpg $

To the OP. If you are interested at all in the truck, my advice is look it over good, listen to it, drive it and get the last 8 digits of the VIN. Have a Dodge dealer run the VIN and see what comes up.
Where are you on the river? Just curious, have friends at Havasu.
I'd buy a new 6.7, but would be careful of a used one. 18,000 miles on an 08 sounds OK though. I bought mine Jan. 08 and at 20,000 now. Not a daily driver for me and certainly not an economy car. Good luck.
