Harvey I agree with you there as I mentioned above Im not looking to start any wars here nor am I comparing a 1st or 2nd gen to the new 6. 7 because when it comes to driveability and power there is no comparison the newer 6. 7 is in a whole different realm the only point I was trying to make is we can send man to the moon with a 4x4 and run around why cant we / shouldnt we expect an engine thats capable of better power with at least the same mpgs as a 20 year old truck??? When your sacrificing gallons of fuel to make less emissions is that really bieng "greener"? The only thing thats greener is Jedd Clampets a. k. a. the oil gods pockets if you ask me its nothing but a money game send the technology the wrong way to make the working people cough up our hard earned money so the billionaires can continue their lush lifestyles. Ok Im done now sorry for turnin your thread the wrong direction CKaza

The issue has nothing to do with rich vs. working folks. I will never defend the epa green weenie types who shove the emissions control crap down on us. What I suspect you don't understand when you speak the rich vs. working folks baloney is the political party you vote for supports and includes the green weenie types.

Speaking of baloney... And which political party DOESNT support the epa, Harvey? Ya know what now that youve turned this into a dead end political battle of wits Ill respectfully bow out. Excuse me while I go make a sandwhich

It is true that a 12 valve can be modified to produce similar hp and tq numbers to the new ones but I disagree very strongly that it can be done without sacrificing the smooth, easy drivability that a new OEM 6. 7 provides not to mention the lack of a comparable transmission. I had an '06 with a very tough and durable 48RE but it gave up a lot of drivability to achieve the strength.

My 98 12 valve has 300 rwhp the 11 has 304 rwhp the 11 out pulls the 6,500# lighter load the 98 had. Also the towing average for the 98 was 10. 5 average honest mileage and the 11 is 9. 5. So I am very happy with the 11 performance amd mileage.

On the 98 I could get 22-23 on the freeway. Not as good with the 11 but towing is where it's at.

If you go to the EPA Fuel Economy Guide you will see a 1500 4x4 with a 5. 7 Gas gets 15 mpg, the little 4. 7 gets 16 mpg, your doing good for a 3500 truck

Harvey didn't bring up Billionaires and Working People, what did you expect Him to say with His reply?

I too did read about DEF for 2013. But that is another cost to fiqure in.....

Back on subject. .

I have not driven a 2012 cuz I know I would like the creature comforts and the out-of-the-box power they have. I think I could live with that mileage you are talking about.

 

[sbattle76]

Mine hasn't budged from 13. 4 to 13. 6 in 2 weeks. No more, no less. I drive 5. 5 miles to work every day. when I haul on the highway I see around 14. 5 mpg, and doing 55 with CC on, and on flat road I see pert near 20mpg on the overhead... . and that doesn't last long at all.

and def is only 25. 00 a gallon!!! we need better factory systems that we do not have to modify or that keeps costing us money THEY ARE $50,000 TRUCKS NOW lets start a mileage war instead of a power war who cares if it will pull 25,000# or 30,000# or more go buy a semi. hey just my rant!

 

[rscurtis]

To add to what Mike just pointed out, the choice is not DEF or no DEF- it's DEF or something else. The something else is more EGR, more regeneration of the NOX catalyst (every several minutes), retarded timing, more soot, and a $100 oil change every 3-4000 miles. Navistar tried the "no DEF" as a selling point and we all know how that worked out.

 

[rwitt]

I drive a 2011 F350 6. 7 Utility Bed for work, and the on hiway mileage is 15 to 16 mpg at a daily weight of 11,000lbs. Normal everyday driving is 12 to 13 mpg. A tank of DEF (approx. 7 gal. ) lasts about 7,000 miles. That being said, I wouldn't own one of the new Fords based on my driving experience with them.

You 4th gen guys are struggling to get 14 mpg roughly, so if a DEF/SCA system would give say 18 mpg then you would save $1676. 00 in fuel costs at $4. 19 per gallon. Say it took 20 gallons of DEF to do so. That's about $80. 00. You still save $1590. 00 or so. I am having trouble seeing a downside to this... ... ... .

JMHO.....

Mike.

Although I agree with your analysis I think you are off on this one. I personally am expecting a one, or maybe two mpg increase with def, but I'm no expert... I do think that the oil should stay a little cleaner, another savings...

 

[RonD]

If you think DEF will solve all you bad MPG issues, just take a current C&C Ram with DEF, and compare it to a non DEF current pickup, there will be you answer

My son has a 2011 Dmax QC,DRW,4x4 that replaced his oldest truck (a 97 DRW Dodge). It is on same job (halling ERS trailers 99% of time, @ 7-8Klb. )as 4 other DRW dodges,(04,04. 5,05,99). It requires approx 5 gal of DEF every 4000miles. ALL of these trucks avg 12-14mpg season dependant and see high idle time at times. The DMax is doing as well or slightly better and has proven out well. In 50,000 miles(9 months) it has required a heater core change under warranty and a Dually fender clearance light harness. Thats it! NO other issues what so ever.



I realize it has a long way to prove itself yet, but I am impressed so far, and the oil stays cleaner much longer than the 04. 5,or 05 Cummins.



That being said, I would not consider a new Cummins UNTIL it has DEF and reduced EGR.

 

[mwilson]

yeah, or maybe we could wait for them to put electric motors in them for power that would save buku bucks lots of gallons and the planet too! I started this post for suggestions on improving MY trucks mpgs not some trucks mpgs that might be built some years down the road! if you haven't increased mileage on your 2009 thru 2013 ram 2500 ctd or 3500 ctd through modifications then get the hell off of my post and watch your balls get square!!!!!!

No problem, my stuff is gone.



You have my personal guarantee that I will never post on one of your threads again. As a matter of fact you just recieved the honor of being the first person in 10 years that I have placed on the ignore setting.



Have a nice day and be well.

[S.Morris]

Harry was simply commenting on the DEF system and the improvement it made to the Dmax mileage and its comparability to Cummins and hopefully the same improvements in the DEF Cummins.

I felt it would be of some interest to those who have no experience with DEF.

I did also. In the future he can answer his own questions.

 

[Tractorat]

I'm first time diesel owner with a 4th gen cummins ram 3500 getting mid 14's mpg with 16,500mi dealer said it will improve with more miles but, I want to know if this is BS or what you guys are doing to improve your mpgs thanks!

Did you not do some homework about what kind of mileage you would get before you bought the truck ? If you did not, that was a tragic mistake.



According to the posts above, you seem to be getting fine mileage for your year of truck. You are correct, the new trucks cost $50-$60k (?). I wouldn't pay that much for a truck, but thats a personal decision.



I would bet dollars to donuts that the car mfg figure that anyone that would spend $60k on a diesel truck would not hesitate to pay $4, $5, $8 per gallon. So, they build for power, and are bound by the political constraints of emissions.



BTW, 16k miles is brand new and not broken in. And if you believe what the sales guy at a dealership tells you, you are quite naive.
