2012 2500 4x4 mileage average?

[HerbW]

Hi. I’m thinking of trading my 2015 Ram Ecodiesel for a stock 2012 2500 6.7 diesel 4x4 with only 60k and one owner.
There is an upcoming EGR cooler recall that replace the stock one on my Ecodiesel. So far the dealership can’t get simple oil changes or recall records right. I don’t want them tearing apart the engine and f..king it up. I’m so tired with FCA , Ecodiesel recalls and their crap.
Any real mileage of the 2012 setup? With deletes? It’s older and out of warranty so I think about changes. Thanks again, Herb

My 2012 did 12.8-13.8 in country/city driving. Towing was 9-12 depending on load/wind, etc. About 20-25% lower mileage than my 2015 and 2018 do not towing.

My stock 2012 averages 13 mpg around town, 16 mpg highway, and 10 mpg towing our 11,000# 5th wheel. I do have an Edge Evolution emission intact tuner but haven't towed with it enough yet to see if it makes a difference in the mileage.

Stock i got same as Hand tools,

Deleted i saw 15-17 city, 21hwy, and 14mpg towing 10k

having done an s465 2nd gen turbo swap, clean burning tuning so i have no smoke, fass 165, ssd3250 gk clutch i get 18-19 city, 26-27 empty hwy depending on tail or head winds and traffic, 15-16 towing 10k. by best setup for my truck yet and honestly has all the power i'll ever want or need being in Dallas and you really cant use more than they legally or safely.
