New Dodge Questions
Hi Guys,
Well to start off on the right foot I am a Ford guy. I currently drive a 2008 F350 6.4L and to be honest it's the best truck I have ever owned with 155,000km's on the clock and not a single issue. That being said I'm going to be in the market for a new truck soon and a couple of guys I work with drive Longhorn's and I must admit they are a beautiful truck. Just wanted to know what I can expect for MPG out of a 3500 CC SRW, 4x4 with a diesel?? Also any major flaws as of yet that a guy should be aware of as far as the engine goes? Any help or advice you can offer would be appreciated and just might make a Dodge owner out of me yet. Thanks

The only thing I have heard about the 6.7L is that if you want it to be somewhat like the 5.9L you'll need a DPF delete as well as an EGR delete. With all the new clean air regulations that the government passed back in 2010 those components are on all the 6.7Ls. Dodge started doing that back in 2007 when they put the BlueTec in their engines. Heres a little insight..
BlueTec is the emissions hardware installed on all 6.7L Cummins engines. It consists of a diesel particulate filter and an exhaust gas recirculation system. The soot from diesel combustion is captured in the dpf and periodically reduced to ash by raising the temperature level in the dpf by a process known as regeneration. Soot and NOX emissions are significantly reduced by BlueTec and meet the new 2010 emissions standard for diesel vehicles. In other words if you want to roll coal and all that stuff you will want to get the EGR and DPF delete. And be careful because I know some states forbid you from doing that with the yearly emission checks and what not. Where I live we don't have to deal with that crap...The 6.7L has more Torque and Horsepower than the 5.9L coming out of the factory. The newer 6 speed tranny also makes it nice. I've driven the 5.9L before but not the 6.7L yet. I'm kinda still on the fence about the 6.7L to be honest. Not a big fan of the things you gave to alter to make the engine better. If I were you I wouldn't buy a new Dodge. I try to find something older with low miles with the 5.9L. They made the 5.9L up until January of 2007. So if you like that body style then look at 06 or 07... That's my 2 cents....

Thanks for the post although it's not really the info I'm looking for. I'm well aware of all the DPF and regen issues the new trucks have because I tore all of that crap off my truck when I first bought it and haven't looked back. I'm looking more for "real world" #'s from guys who drive these trucks so I know what I can expect for MPG. I'm realistic and don't expect great #'s due to the size of these trucks and what they can do. But I do like to do a little research before I spend the money so I know what I am in for. Again anyone who drives a new 6.7 and can contribute their info, it would be appreciated.
Thank You

all cummins engines have their weak points that can be fixed, and once fixed they will run trouble free for a million + miles.
early 12vs had a weak woodruff key in the timing gears that once fixed wasnt an issue anymore.
24v vp44 motors have weak lift pumps that cause injection pumps to fail, replace with aftermarket lift pump and you can get a few hundred thousand miles out of the injection pumps.. especially when running ashless 2cycle oil in the fuel
3rd gen common rail 24v motors have cracking injector issues...just keep a close eye on rail pressure and make sure its in check, and run some ashless 2cycle oil in the fuel to help prevent jamming/cracking of injectors.
6.7L Common rail motors have DPF and EGR's on them...make sure those fall off or turn up missing, and you will avoid turbo failure and an intake clogged up with soot.
otherwise all good motors
the 5.9L 24v's are all capable of 24MPG (common rail and vp44 injected) as are the p7100 12v motors.
the 6.7 doesn't do as good on economy because of emission controls, and larger displacement. but with emission deletes and a flash tune with lots of timing, they should pull 18-20mpg.

Welcome to DF
Yep, newer emissions suck, but they are on all new diesel engines now. I think 14-18 would be a good ballpark number, expect 8-11 if you tow heavy. I beleive all the kinks have been worked out for 2010+ for the engine. The 2011.5+ have 800lbs torque, my 07 has 610 and wont even break a sweat pulling my camper, i cant imagine what 800 will do.
