After 3,700 miles I've been averaging 17.9 mpg hand calculated running premium 93 octane highest 20.2 lowest 15.2 mpg.
In contrast my 2023 Laramie 5.7 Hemi, 3.92 gears on 22's averaged 15.6 mpg combined highest 17.5 lowest 14.7 mpg.
The computer can read 1 mpg higher than hand calculated mileage and other times it's right on.
It's a good running engine and pulls stronger than the 5.7l but the hemi was replaced for emissions and not economy.

I'm averaging 17-18 in mixed driving with my SO 3.92 geared truck. The highest I've got is 24 MPG on a road trip which I though was pretty impressive. So far I have been using straight Shell 93.
lmao, yeah i hate it when they force me to buy ram, i really wanted a ford v8 but nooooo

I'm not sure how that fuel mileage is possible (80 all* the way). I mean, great for you however...
My lightly loaded (maybe 300# of stuff and wifey is 120#) 23' hemi et going 70-75mph average (some less of course with traffic and stops), on mostly flat or gentle hills was at 18-19 using 89 octane on a 2200 mile RT mostly on I20 and I40.
I am a grandpa and drive like one, always dropping out of cruise if approaching a hill so it doesn't downshift etc. I run on aero (2 bars lit up) and have a trifold cover.
Hemi's are strong performers but the hurricane, like my previous Ferd twin turbo, will spank a hemi on the highway.

Wow. I'm surprised you got that mileage with 3.92 Gears. That's great. We are picking up a Rebel soon, so I'm not expecting much better than 20 MPG, which is similar to our 6.7 Cummins at 65-70 MPH with 3.42 Gears. Are you running 87 octane?

It was prob a lower avg speed, smooth roads, with little wind resistance.

I must be fortunate with my G/T!
I use 87 octane and only run in ECO/MDS Mode when going over 50-55mph, otherwise I almost always drive in Tow/Hawl Mode (which I feel is really "Sport" Mode for me)..and I live very rural with LOTS of hills and valleys in SE Wisconsin..and still average 19mph (daily "city" driving) while making that G/T exhaust bark.
I do have the "mpg friendlier" 275/55/20 Bridgestone Deuler H/Ls set to 38psi cold..and they will warm to a steady 41psi quickly after a few miles. This setting gives me the best comfort and handling..and mpg(?).
Zero mpg complaints from me!!

I've been using 93 octane from the start with combined mileage lately being 16.2 mpg hand calculated although the computer was spot on.
The mileage dropped with Winter blend fuel that switched on 9/15/24 with Summer blend I got 17.4 mpg.

I averaged 19.9mpg today on a 400 mile round trip mostly highway @ 70-75mph in 2025 warlock with 3.55 gears. Pretty happy with that considering the heavy factory tires

Well, I was doing 80 MPH on a 500-mile trip today and was wishing my truck had the 33-gallon tank. The truck indicator said 18.3, I think. I'll update you when I fill up. It's not terrible considering 33-inch tires, 3.92 Gears, and east Tennessee hills. If I wanted great mileage, I'd drive 63 MPGHin a Prius with a "I'm with her" sticker.

Yeah I am getting about 15 to 16 between HWY and city. i blame it on my heavy foot, the 392 gears, and aggressive tires..Then again, i didnt buy it for the MPG, i got it because I wanted the newer engine after owning several HEMI v8's.. the 5.7, the 6.1, the 6.2, and the 6.4..

I got 17.2 mpg hand calculated with the last fill up and the truck indicated 17.0 mpg.
It increased by 1 mpg from the previous fill up maybe that recently installed Rough Country soft tri fold bed cover helped.

With 2500 miles on the new warlock lifetime avg is 16.9mpg. Not too bad it has roughly 100 miles of towing time with my boat @ 5k lbs and 250 miles towing my 18ft open car hauler with up to 6k behind it between trailer and load. I have hit 20mpg on a long highway rd trip watching my speed. 3.55 gears . Hand calc vs computer is always .1-.2 diffrence with the computer avg higher.
