No question there. The deletes certainly pay for themself in fuel savings, but also longevity, power, and the general benefit of one's investment. No matter what one's actual specific numbers are, there is a quantitative and valid MPG improvement to be had as many have stated and have proof of this fact.

if you recall mega in the h&s post we had talked. I posted exact numbers driven vs. the amount of fuel I used. If I recall I averaged 18mpg hand calc`d and confirmed towing heavy. So my numbers can speak for themselves after all it`s my wallet that I would be lying to anyways. hehe

mega-engr

Yes, I do recall that and it is still hard to fathom. I'm lucky to get 18 not towing at all, let alone towing heavy like you said. You must have something very aerodynamic to tow..., and weight is not a real issue. You towing downhill?

I made an almost empty run last weekend. No trailer this time, bt there was plenty of junk in the bed. I kept her to 58-60 the whole time thinking I could get into the 20's. NOPE!!! 17.7

Mopar_Mudder

Thoose number I believe, I would be floored if I got 17.7.

Ramped, well it must be downhill everywhere you go

Blake Clark

Im just floored that you can get 25mpg outta that truck. My 08 being babied like a newborn the highest Ive ever seen was 20.5.


My fuel sipping anorexic '90 has an all time best of 23.

I get about 16 ave usually with the daily commute. That is 70% hwy.

If I drvie 70 or less, and no wind I will get about 18-19. If there is wind it goes up or down according to which direction.



I baby it pretty good so I have a hard time believing people get a lot more out of these trucks. Mine is a 2010, 4X4 auto.

I have hd a number of these trucks and never had one yet that would get over 20 consistantly.

When running locally empty on freeway and city street 16.5-18. Pulling 10K trailer around the country 11-12 doing a pretty constant 65.

Mopar3500

Around 16 city, 19-20 on the highway if I stay at 60. auto, 4x4 4:10 gears

Mopar_Mudder

Have you done any mods to it?

Are the numbers hand calculated or the computer?

I ask because I have the same truck and get no where near that, but the computer says I am. 15 is pretty much tops.

Mopar3500

No mods at all. I am also going by the computer above. Might have to do a more calculated assessment.

ctnv

Hand calculated, empty, 17-19 if a stay under 70mph. Towing/hauling 11k I get 9+-11+ depending on the speed and slope. 2007.5, HD, quad cap, 6.7, 6sp auto, 3.73 diff, only cold air dry intake.

I'm running around 16 straight city, and 20 on the highway. I did a trip through the mountains of east Tennessee and back with 3 adults, one baby and a bed full of bikes and camping gear and I hand calculated my next fuel up at 19.6 MPG. Last winter I did a 3000 mile trek across America, the bed loaded with ~500 lbs of junk and running winter blend through all of the blizzards Nebraska and New Mexico, and I still averaged mid 19's. With summer diesel I average better day to day than winter, but so does everyone else.

5" TBE, EGR disable, S67ME
2008 2500 QC 4X4 w/ 3.73's and it's an auto

OK, It's time I jumped in. I've stayed out because I don't want to be called a Liar on the numbers.
I'm getting 17.4 (Ave) around town, running Freeway from Portland, OR to Seattle (round trip) I've been averaging 22.3 empty and 12.8/14.0 towing the 5th Wheel. If I know there's water where I'm going I run the 5er empty and hook the water when I get there. These are Hand Calc'd mileages and based on 35,000 miles (15K pulling the 5er).

Mopar_Mudder

Yea your computer numers sound about the same as my computer numbers, but if it is like mine they are way off. I have a 30 mile trip one way to work each day all at 60 mph. One tank this summer I decided I was going to see what milage I could squeeze out of it. Always took off using light throttle and let off way early to coast to stop sighns. The computer hit 20 mpg and I really thought I was doing something, ran the entire tank and filled up. Yep I got 15.5 mpg actual So know there is no ***** footin around, I can drive it like I want and get the same 15 mpg.....
