Any of you all have a 2017 or so Ram 2500 with the 6.4L gas?

For those of you that have changed tire size and NOT adjusted the speedo, do it. You will see a meaningful increase in real mileage. I used the AEV procal. Letting the computer know the actual tire circumference adjusts things in some way that I don't know enough about that you will see a real improvement in the way the truck drives and the economy.

This has been the case on every late model Ram I have had for the past 10 years. 4 trucks. 3 of them HDs.

Fill it up and drive , then fill it up again and use a calculater. The dash computers have a tendency to exaggerate.

We have a 4500 at work. It’s a 16/17 model. It does nothing impressive. Think it averages 6.5mpg

My hunting buddy had a brand new 2017, 3/4 ton, 4WD w/6.7 liter.
Kept telling him he needed to look at a diesel because he did alot of driving.
I rode in that truck several times. Just going down the road, the danged thing was constantly shifting! (?) Made no sense because it was an automatic.
Less than a year later, here he comes with a diesel!
The other truck was a real gas guzzler....and the constant shifting was irritating!

4500s will have small tires and super low axle ratios. They get crap mileage no matter the brand.

I won’t disagree with that, and don’t expect a truck with a lot of idle time to have good mileage. Still doesn’t help the fact you put a trailer behind it and it won’t pull itself out of the way.

2023 Tradesman 2500 with 6.4. Love the truck. Just did a 300 mile road trip this weekend. A mix of steep grades and flat highway miles. 75-80 mph, even up hill.

14.2 mpg for the trip. Can't complain.

Towing my utility trailer with the UTV, getting around 10-11.

Not trying to fool myself it was built for gas mileage and getting all worked up over it.

I have a 2022 1500 TRX and I get 7 to 8 miles per gallon. I know Im not helping just trying to make a few feel better that get 12+ MPG

A TRX was on my bucket list, but I think you've cured that itch!!

i have a 2013 2500 5.7 hemi and at not even 120000km they have to redo the engine (maybe put a brand new one on it but will see) it was a bargain when i buy it and i had a camper to haul not anymore so once the extended warranty is gone the truck will not stay and no one will cry.

I had a 2017 loaded Power Wagon (6.4l Gas). I put 35000 miles on it without any issues. It was super comfortable and plush. That said the gas mileage was atrocious (single digits was a normal occurrence). Setting the cruise at 80 would frequently result in MPG of 6, 7, 9 I used to send pictures as a joke. One time it was 3 MPG with a trailer on a grade. It was also gutless with anything hooked to it.

I sold it due to the small tank. I know it seems stupid, but I live in MT long highway drives that transition to long FS road adventures are the norm. I constantly had fuel anxiety. I am also not sure how the truck would have held-up long term as I have seen a few of my buddies struggle with Ram gremlins.

I am not an MPG snob either. I have always owned sucky giant motors which is why this one stood out so much. I may have felt differently if it came with a 40gal gas tank with the illusion of more time between fill-ups.
