'06 Dodge/Cummins 5.9L Mileage

I was just curious if anyone else has a new Dodge/Cummins and what kind of mileage they are getting.

I have an ongoing battle with my brother in Dodge vs. Chevy. He's been a diehard Dodge fan and I a Chevy for the past 10 years. Well we both just upgraded our pickups this year and he got the new Cummins 5.9L 325hp 610 ft. lbs of torque. I got the new Duramax 6.6L 365hp 605 ft. lbs of torque. Of course the ribbing continued until he started getting his gas bill. He's been consistently getting 12.5-13, and on a recent long trip pulling a smaller enclosed trailer (20ft) he got an average of 7.5 mpg over 1000 miles. OUCH. Has anyone else out there experience this type of performance with this truck? I've been getting on average 15.5-17.5 and have seen as high as 21 when I stay out of the throttle.

Just Curious.

BTW...he's right now working on a deal to trade the Ram for a Durmax....I WIN! :)

That's not really what I wanted to hear since I'm a MOPAR man myself.  It would be interesting to find out more because soon I'm in the market.  Probably not new because I'm busted broke but I will be looking for a used pickup probably around three or four years old.  Something to make due until I actually start making some money!  I am strongly considering diesel since the gas prices keep going up.  Rather have power and a little mileage edge if I'm going to spend three bucks for diesel vs. 2.85 for gas.  Plus, ethonal will lose it's cent tax shortly and go to 23 cents.  Gotta love taxes.

ND,

Thats GREAT!(INSERT SMILE) I keep telling folks how great the Duramx/Allison power train is,drive and compare and 9 outta 10 choose GM.Heck last week I took a F350 power stroke super crew in on trade,had to drive it back to the shop 50 miles,13mpg's and all over the road.Big difference's between the 3.

Next year Toyota and Nissan is coming after the Big 3,both will have a 1 ton pickup with a all new V-8 and they will both offer diesel motors,we'll see what happens but I'll be surprised to see an 8ft plow or a 5th wheel on these puppies.

Sounds like the older ones haven't been too bad. His brother-in-law and a couple other friends have 05's and have been getting decent mileage...around 16-17...but his '06 is really thirsty.

snow,

You best be sniffin' out a used Dura for me.  I had already decided it was a Dodge or a Dura.  Only thing is, I like the rounded fronts on the old GMCs and Chevys.  Suppose I'll have to settle with the kinked hood look though.  Weren't the '06's going to go back to the rounded front?

Ha ha, I see you were typing while I was posting.  You answered my question without even knowing it.  You truly are a genius.

Now, find me a steal on a used Dura.

Timmer's,

Let me know when ya go-on point! I'll steer ya in the right direction and keep away from the 02's and 03's,not that they were bad but unless the injectors were replaced under 100k(warrenty issue) very spendy item(internal injectors)If ya find one with the work already done by a dealer GM has extended to warrenty out to 200k,then you'll be fine.

Tim,

I should have posted this a few months ago. I just traded an '05 Duramax. I work for a division of GM and usually trade every 12-18 months, so should have a good clean '06 on the market by next winter early spring. When were you looking at moving...If sooner I'm sure snow can point you in the right direction. If at all possible I'd look for an '06 with the new 6 speed...I love mine..and the LBZ (365 hp)...definitely a noticable difference over the LLY.

You won't regret the choice.

I have an 04 cummins and my brother in law just bought an 06 and we both get 17-18 mpg on the highway if we keep it at 70-72 mph, which is about 200 rpm's. There is either something wrong with his truck or he has his foot on the floor all of the time. I get 13-15 towing a 19ft fiberglass boat.

That's what I asked him..cuz he usually is on it a little heavy. He said ever since he's gotten this one he's been trying everything to bring that mileage up, including slowing down a little bit..It hasn't really mattered much. This weekend, on his 1000 mile trip where he got about 7.5 he said he was averaging about 70....and much of that was in ND where the speed limit is 75. :) That's no fun...

You're right though..could be the luck, or the un-luck, of the draw.

Yeah,there is alot of factors in figuring mpg's,"foot-in or out" of it,tire size,tread,tire psi(to much or to little)driving terrain and such.All I know is whether its gas or diesel its time for our manufacture'ers to put their shoulder to the wheel and help us get milage outof our rigs!I read today that Exon had another record quater,4.5 billion!

I'm currently testing/driving a new 1/2crew with the flex fuel motor and like the lower cost of operation burning E-85,I change off E85 with unleaded every other fill and do not lose milage or performance,just a little extra saving's at the pump.

snow, are you sure about the E85 getting same mileage and performance? I've heard many times mileage drops significantly and your savings wont be there when the tax break disappears

Speaking of Exon having another record quarter, what are the fuel prices running around the state? #2 in Grand Forks is $2.74. I saw it in Minnesota this weekend for $2.63.

One thing that may be affecting these new diesels, is that either this model year or the 07's must conform to EPA Tier 3 Emission requirements. I know for certain on farm equipment specifically John Deere that the 2006 models have made this change and it wouldnt surprise me if the Auto industry has this year. Im not positive on this but I know for fact that by 07 they must conform to these new regs. I myself will soon be in the market for a Chev. with the flex fuel motor. My family has an 03 suburban and an 04 Silverado and we burn E85 in both. Yes there is a loss of about 3 mpg's on the ethanol, but the benefits as far as cleanliness and supporting domestic alt. fuels mean WAY more to me than 3 mpg's do. With oil closing at 70.40 today, it is time to look here at home and let the middle east and all the problems keep their own dam oil. New biodiesel and ethanol plants only mean progress for the midwest and I dont know why some people will not embrace this. As far as I'm concerned its a no-brainer and Im still a young punk that is still in college. But thats my 2 cents, Drive American!

Hey Guys....I have a 06 Cummins and i get 22.5 on the highway. I only have 3700 miles on it so its still brand new yet and I am very happy with the milage so far.

Dodge made some dramatic changes in regaurds to EPA standards in 2004. My 2004 Dodge Cummins has a catylitic converter on it, I know this was the first year they started putting them on. my Cummins also has a extra injection cycle during the exhaust stroke. 2 more reasons why fuel economy fell begining in 2004 for the dodge cummins. Prior to 2004 it was common to hear Dodge owners getting 22 to 24mpg highway. I average 19/20mpg highway(if I keep it under 2000rpm), 16/17 city.

3X,

Yup,I'm sure,unless the "instant econmy" is malfuctioning.There is alot of mis-information out there about E85,I'm doing my own research so I can inform my customer's.I do know it takes 2-3 tanks of E85 to fully convert the motor to the point of losing 20% of power but by mixing 87%octane with E85 I have'nt lost power or mpg's,thats running empty,the ECM makes the adjustments needed for fuel mixture.If i'm pulling or have a payload I'll run regular unleaded.

E85 is actually 105octane fuel,it just has a lower BTU rating.

So far so good,I also am impressed with the "DOD" (Displacement on demand)5300flex fuel motor in the 07 Tahoe (also called Active fuel management)But again the jury is out,they are selling as fast as they are coming in,but if all the facts are true this motor is a step in the right direction.

I had a 03 Duramax and just went to a 05 cummins. The cummins kicks the duramax's butt. I chipped the duramax and the best I ever got was 17. Now I get between 17 and 21, without the chip. I'm completely satisfied. I do have the chip for sale that was in the 03 chevy if anyone is interested. Fits 01-05

I had a 92 and a 97 dodge, they were both POS. There gas mileage was crap and the transmissions and rear ends are junk. My opinion based on my experience with dodge.

I now have an 05 durmax, get around 21MPG avg and no issues. Very Happy!!

I have an 04 Dodge cummins with 55,000 miles and I get anywhere from 17-21 on the highway it all depends on how fast I want to drive. I drove across the state yesterday, drove 80mph all the way and got 17.1, now if I slow that down to about 72mph or less it would be 19-21. I noticed a significant improvement around 40,000 miles in the mileage. Brand new 18 was probably the best that I did. I know three duramax owners and none of them get better mileage, one of them gets roughly the same, but it has been chipped, my truck is stock. It has been a great truck overall.

Ford has been hinting at a 1/2ton diesel truck for the last few years, but no official announcement yet. I am sure it will be running an international diesel motor in it anyway. Haven't heard anything from dodge or chevy about a half ton diesel.

There is chatter about a 5cyc diesel coming but its a couple years out thats the last I've herd for the 1/2 ton.

05's,06 and 07 classic duramax has the upgraded allison 6spd tranny and you'll get 20-21mpg's @70mph (stock powertrain)

Snow,
Yes you can "re-Chip" witht the same programmer. You have to unistall from the 1st truck and install onto the next truck. If you try to just install onto the 2nd truck the programmer will tell you that the VIN's don't match and you must do the above to complete the task.

I have done it by uninstalling the program and reinstalling then back to my truck!

All went well I guess - $900 later. GM claimed there is not a link to the injectors and fuel pump causing problems for each other. Still have 70k left on the injector warranty.

Did you come into ND for any duck/goose hunting this year?

Hey snow,

I meant kick butt in the sense that it does have better mileage. My duramax only got 17.6 one time, other than that I got around 13-15. With the cummins I get a minimum of 17 even when warming up and being cold out. The chevy did have better hole shot though-- probably because of the oversized tires on the ram.

The thing to remember is if the gears aren't the same it's like apples and oranges. You will get better mileage with the 3:73 vs the 4:10. I believe Chevy uses 3:73 almost exclusivly as Dodge uses both. My buddy and I both have 03 cummins and with my 3:73 gears I average about 17.5mpg all around driving to his 14-15 with the 4:10.

Snow, FYI,

I picked up a tank of E85 in Sioux Falls last week. I noticed a 1 mile per gallon drop and it was mixed 75/25 (75%E85)in an 07 Yukon. Noticed no loss in normal highway driving power. The one thing I did notice is that is smelled differently as it was burned, smelled like burnt kayro syrup, but on the other hand I paid around $1.70 a gallon. Might just have to add some of that smell good stuff to the gas so the exhaust smells like cherries. LOL

Wow! I'm a little shocked Bought my 1 ton  truck new 07 dodge megacab cummins originally got 18mpg hwy changed to aero muffler, powerpuck w/ predator programmer set on economy, amsoil motor oil, amsoil freeflow air filter, toneau cover and use any diesel with prirose 405c cetane booster .  I drive a lot in Oregon on I-5 cruise set at 57mph in the truck lane and always gets at least 24 mpg.  and 18mpg w/ loaded utility trailer 14mpg with loaded 14000 pound 5th wheel on highway. tips for fuel economy first make sure your tires are pumped up and not squatting, keep your air filter clean, use an inexpensive cetane booster. and keep the cruise control on and at the lowest speed you can handle in the highest gear, over 50 mph usually gets you there.  hope this helps.

ive got the 06 ram and love it. it aint thirsty at all by any means. put a few mods on it like cold air intake,bigger free flowing exhaust  turboback and a chip that will give quite a few extra mpgs. when i got the pickup brandnew it was like 16 at best even with the reak in period to consider.but at 40k i put all of them mods on it and now it gets a solid 22-24 load free.not sure what it gets pulling a load all tat gets pulled by it is a boat or fish house..very happy with the mileage it gets

Ethanol has 66% (2/3) of the energy as the same volume of gasoline. When you blend it to E85 you have 70% of the energy of gasoline.

So from strictly a mileage standpoint, if the E85 is priced higher than 70% of what gasoline is priced, it is not a good value.

Also, an 06 cummins 5.9 not getting 11-12 MPG towing hard and fast? Something is not right. Never got less than 13 pulling 4 sleds at 80 MPH in Montana when figured off the pump. However, the emmisions (exhaust gas recirculation and common rail injection) does give up 1-2 MPG.
