35 avg mpg

[VernDiesel]

3.21s basic engine & transmission tunes ie working def full exhaust etc.

To be fair while it is over 2,000 miles it’s also mostly 65 to 70 mph hwy.

That’s still amazing.

That’s awesome! Best I’ve done is 35.4 mpg in 200 miles of Michigan 55 mph backroads. Did average 31 mpg from Portland, Oregon to LA to Kalamazoo MI.. that was a long drive.

 

[Chris3058]

I get nothing close to 35 with 3.92’s. Hit maybe 30 a couple times on long trip across the prairies once. But 27 is doable in the summer on flats at a reasonable speed. Already seeing the winter diesel
Blend dropping MPGs.

I would say during the summer my average is 27-28, all interstate at 75mph. I also have my bed completely full of multiple tool boxes . Probably 200-250 lbs worth.

Sad that it has been discontinued for 2025. What are they thinking? Not listening to customers anyway.
I don’t know what % of owners chose the diesel but as it is, RAM has very few engine options. Going forward in 2025 they will have one less.

If it lives up even close to its hype, when my EcoDiesel is ready for me to trade in (i.e. in roughly 3 years), I will happily trade it in for a new Ramcharger. They are due out as a MY25 vehicle. I expect in 3 years they will have gotten out all the major bugs and it will be sorted out well-enough to make me very happy.

I think I may have gotten the runt of the litter, I have no clue how you guys are hitting those numbers. The best I have gotten in my EcoDiesel is like 22mpg, granted I'm running 315/45/22 Recon Grapplers but I dont think it should knock me that far down.

I just did a fill yesterday and EVIC said 26 on the nose. Hand calculated was 25.84. Not to bad with winter fuel here in Wisconsin and about 50-50, 4 lane versus 2 lane.

Sadly, I think it does.

I only went from stock 32 to 33" tires and Fuelly says it cost me something like 1.5 MPG.

The mileage will be off with the larger tires. I went from stock 275/55 20’s to 305/70 18” and the difference is ~10% on tire size corrected by Banks Tuner on speed
