I'm considering buying a Ram 2500 CTD for my new towing rig, as my 99 Durango struggles to tow my 23' boat. After some research, it sounds like the DPF and other smog equipment on new 6.7 Cummins engines really hurts the MPG.

To all you CTD owners out there, what model years are the best for fuel economy?

Thanks for the help.

 

anything older then 07.5 model year had the 5.9 and better milage

 

Unless you do deletes! I'm doing better than my dad's old 5.9

 

03/04 get the best from the Common Rails. Other than that, a 12v

 

I have an 2007.5 and want better mpg, you say do the deletes. What all is involved in this? How do you do it? Lookin gfor recommendations.

 

I have a 07 5.9 and live in Upstate NY.With the crap winter fuel thats split im getting 18 mpg on the back country roads and alot of idle warm up time,really never get above 50 mph in the snow so im thinking come summer with better fuel ill get 19 ,maybe a little more.

 

I did a DPF-delete last March. See this thread: https://dodgeforum.com/forum/dodge-c...installed.html
