Curious what you all get in the city/hwy with the 2019 2500 6.4L with the 4.10 gearing, 4wd cru cab if possible. Thanks in advance.
 
1400 miles on 6.4L 4.10/8 speed. Early flat-Florida numbers around 10mpg in the city and 15mph on the highway at 70-75. I think 17/18 is possible at 60-65.
 
I have about 7,000 miles on my rig with a 6.4L 4.10/8 speed. My current mpg is at 13.2 after many short trips driving on a combination of city and country roads. I live in Michigan, so that number is also affected by extended warm up idling. Last summer on some longer trips I was able to achieve almost 18 mpg driving 55-65 mph.
 
~7000 miles on 19 Power Wagon 6.4L 4.10/8 speed. Averaging City 11.5 Hwy 15.5. Best I've seen on the flat highways of Oklahoma is 17.5 with a slight tail wind between OKC and Dallas. I use adaptive cruise control almost constantly on highway - even in rush hour. I typically travel at speed limit up to 70mph, but rarely over that.
 
i bet that acc eats it up, we got a brand cherokee 8 speed and i tell you the tranny really ramps up to get back to speed,my taco barely gets 16-17 so i can hardly wait for one of these dealers to wake up to a realistic price for a 19 in 2020!

I imagine that drops at 80+, in SD the Interstate speed limit is 80 but most traffic is doing 84-85. In my 18 Jeep GC 5.7, I was getting 19-20 on the interstate with the adaptive CC set at 84, assuming I'll be a little over half that in the PW.
 
2200 Miles on a 3500 crew cab DRW and 4x4: average 13.5 to 14 mpg with an empty truck (combination of city and 70 to 75 mph highway driving).
I've notice an additional 0.5 mpg if I feather the throttle gently from a full stop, kind of like a 90 year old driving to church on Sunday morning.
 
I have 4000 miles with a 4.10 since December 2019. Towed a 10,000lb toy-hauler 400 miles roundtrip here in flat Florida at 10mpg. Plenty of grunt and smooth as silk. Unloaded in the city 10mpg. 65 on the highway 17-18mpg. 80 is 14-15mpg.

Just had an image of a 90 year old in an HD ram pulling into church. Im sure she'd need jesus to get down from that truck

LOL... he / she would be the coolest 90 years old !! :cool:

Regardless, my old 2005 RAM 3500 4x4 dually Diesel (the silver one on the left of my avatar picture) when it was new it consumed about 14 to 15 miles per gallons, it wasn't before it reached around 80,000 miles that the mileage improved to a consistent 16 to 17.5 mpg !!
And same goes for the oil consumption as well: first 10,000 miles it was about a half quart low, then gradually improved to zero oil loss at around 100,000 miles (with 10,000 miles oil change intervals).
Fuel consumption from 100,000 to 230,000 miles gradually decreased until the injectors failed. I then replace all 6 injectors (got them from "Injectors Direct") including the CP3 pump and instantly got right back to 17.5 mpg.

Oil consumption increased from 100,000 miles to today's 350,000 miles, of course I changed the front main seal at around 250,000 miles and recently the rear main seal during my last clutch replacement at 320,000 miles.
Now, at 350,000 miles, with small oil seepage(s) here and there and considering the pistons rings wear: the engine uses about 1 quart of oil X 10,000 miles. Not bad for that kind of mileage !! :)
The truck is used on a daily basis to carry construction materials, since the day it came off the dealer lot.
 
I understand the theory that the 3.73 gears should be better for gas mileage but based on the feedback I have seen here and elsewhere on the ‘net I’m not so sure that there is any difference in the real world. I primarily purchased my Ram 2500 for towing. I don’t believe there’s any scenario where I would find the 3.73 gears a better option than the 4.10’s that I have. I’ve seen plenty of comments from owners that regret buying the 3.73 gears. I have yet to find anybody that bought the 4.10’s and wish they had gone with the 3.73’s.

Last night we were making the 80 mile return trip from the cabin. All but 5 miles is 65mph highway and I had the cruise control set at 64. I reset the dream-o-meter just after leaving the cabin and when I pulled in to the driveway at home it said 19.2 mpg average.
The conditions were perfect. Cool enough that we were not using the air conditioning, midgrade fuel in the tank, no headwind, mostly flat with a few rolling hills. My truck likes 64mph much more than 65. It will run in eco mode about twice as often at 64 as it will at 65. That sweet spot will drop down to 62-63 without the tonneau cover.

I was impressed. - PeeWee
 
Yeah, my 3.73 CCLB is getting the same MPG on average as what I am reading on here. I’m also becoming convinced that when these trucks get worked hard they last longer. It seems like every guy who’s getting into the deep 200 to 400 thousand mile range works the **** out of them.
 
With the current 8 spd I don't think all the 3.73 regrets will exist. If someone wants to tow regularly or run heavier and larger than stock tires for sure the 4.10's would be the better choice. But my 2019 4.10 truck seemed almost geared to low for my around town errands running the 275/70/18 stockers. I would like to cruise at 70 mph so saving 200 rpms works for me.
 
Just over 2,000 miles on our 2500 Mega and so far getting about 12.8 MPG in mixed driving using 89 octane. I am glad I went with the 4.10
 
With the PW (6.4/4.10 gears) and the 35x12.50r17 Nitto Ridge Grapplers at 85 I'm getting around 11-12mpg, at 70-75 I can get around 14-15. Around town I get 12. Towing just depends on the wind, 6 into it yesterday and 10 coming back.
 
The 8 spd has a slightly lower OD ratio than the 6 spd did, I believe .67 vs .65. 1st is also much lower and the overall spacing just makes better sense. I also looked at a Ford with the 10 spd, they kinda match up wit the Ram as 7th is 1:1, 8-10 are OD. Most guys towing are never seeing those gears from reports I’m seeing. They have really stupid options as well, 3.55 or 4.30. You can get a 3.73 in the F350 which is probably what I would have done had I gone that way.
