In shock and a migrane!!

[bsheen]

Just picked up my 2022 2500 6.4L Laramie on friday from the dealer. Keep in mind I'm coming from a 2015 F150 Lariat 5.0L.

I've seen quite a few people saying they are getting 16mpg and even saw a guy on youtube that was getting 18.5 with 35s and lifted.

So.....needless to say I am really disappointed that I am averaging about 10mpg at the moment with 380 miles. And quite frankly sick to my stomach. I never thought I'd be getting this bad of fuel mileage. I am running 35x12.5x20s. As much as I am pissed at myself for thinking I was informed, I'm equally irritated at RAM. They claim they won't list mileage on the HD series truck because they "don't know how we're going to use them." Well I have an idea, How about to give a vehicle "alone" rating and let people decide on their own and how it will affect the mileage. I knew on my Ford if I got 18 in the city I would likely get about 14 pulling my trailer. Am I to assume I'll be geting about 4 mpg with this setup!?

Knowing what I know now I would have ordered a 1500 which appears to get 17-22mpg, considering I pull my trailer from one site and leave it until I am done.(could be 2 weeks to 4 months).

All said I absolutely love the looks of the truck.

It's too early to get despondent. My mileage got better and better as it got more miles on it. That said, it is a 3/4 ton truck so don't expect miracles. I get 14.5 ish varied driving. I get 17 on a trip and 9.9 pulling my 9k trailer.

 

[392DevilDog]

There are guys only getting 10 mpg with a 1500 too.

I stopped thinking about it. I just drive and fill.

Sometimes I get 16 sometimes 8.

The only thing that truly affects it is your ability to coast as often as you can...lol

You're currently on winter fuel - loss of 1-2 mpg.
You're running heavier 35" tires - loss of 1-2 mpg.
If you haven't calibrated your speedometer for the new tire size - difference of .5-1 mpg.
At 380 miles you probably just finished the first tank in the truck. Rest the EVIC with each new tank and continue to monitor over the next few years as the engine continues to break in. You don't have enough data on the truck yet.
BTW, my 2016 Power Wagon gets 13mpg combined (not towing) in the summer, and sometimes 16 mpg on a long trip with lower speeds.

Fill up reset the trip meter set cruise at 60mph and don't stop for 200 miles. You will get much better than 10mpg. I have 35's and speedo calibrated for correct tire size.

I have a ‘21 2500 Hemi and get 9 towing a loaded 5W. Mixed driving in 14-ish and I’ve got as high as 19 on a flat interstate. Your mileage will improve with time, remember you’re driving a 7k lb tank.

 

[Firebird]

My 6.4 was thirsty, and I had 4.10 gears. It's a big Hemi, and a heavy truck, they do not get good economy

 

[star_deceiver]

None of the big 3 publish fuel economy figures for their HD trucks… (news flash: none of them are good)

I‘ll wager that you‘ll probably spend $15000 to drive 60000miles….

 

[68PowerWagon]

As mentioned above, you are currently on the winter blend. I easily lose 2-3mpg during this time of year. Here in a couple of months when we get back to summer blend & it is broke in a little more I expect you will see a 3-4mpg improvement.

 

[tron67j]

The shock is obviously painful but moving from a 1/2 ton to a 3/4 ton is like moving from a regular hammer to a sledge hammer; it is going to take more power to move and you will get less swings out of the same energy. While some things like winter blend, etc. may allow you to see a slight increase in mpg, you need to make peace with it will never be like the F-150. Before you jump ship, you really need to consider what you require the truck to do, as in are you towing things that require the 2500 and if so, it is what it is. One thing, don't trust the computer, run a couple thousand miles in different conditions and do manual calculations to see what it really is. Not going to be super, the one period I checked I got about 13.5 but I have a Tradesman without huge tires and don't carry a bed toolbox or other extraneous weight and don't mash the pedal. However, I stopped checking because I need the truck and I like to drive it, do I accept the MPG.

Good news is you could probably trade it in at full value and get another 1/2 ton if you aren't towing a lot. Ford has a heavy towing package for it's 150, maybe that will help. You could check Carvana and CarMax and see what you could get selling outright. As far as not listing mpg on sticker, well that is part of the lobbying effort where the big 3 got it removed along with forcing car sales through a dealer and other benefits for us (them). It is what it is. Good luck with whatever you do.

I never got above 12mpg with my 6.4 power wagon.

 

[EnigmaMan]

If it makes you feel any better, I had a Ram 2005 1500 MEGACAB (yes it was a 1500 they did make those) with the 5.7L Hemi. came with the 8 lug rims and everything. It never got about 10mpg in the city and maybe 11.5-12mpg on the highway. it was a 2wd stock truck too. I think a lot of it has to do with the powertrain losses and efficiency within the transmission/ rear end not to mention the sheer weight of the thing too lol

 

[cashman070]

i was always told - you own a truck you don't worry about mpg cause if you do then by a prius....

 

[bborzell]

I find it interesting that many discussions about less than satisfactory mileage lack details about the basis for the apparent original expectation as well as critical specifics about driving conditions.

My RAM is a 1500 ‘22 Lariat, 5.7L etorque 4X4 with a 3.92. The sticker says that EPA rating is 16-18 combined.

After 2,000 miles of winter fuel, I am seeing 15 mpg pretty consistently. I drive at 75 mph as a matter of course. I live at 2,200 feet. Wherever I go, I am either climbing or descending. While descending obviously helps mileage, I don’t believe that it balances out for equal distance traveled when climbing 6-8% grades routinely.

Just for grins, I drove down to the valley and did a 100 mile round trip (2WD) with virtually no elevation change. I also kept it at 65 mph. Mileage came out to 19 mpg.

You will find your mileage improves. Couple of posts from when I got mine in Aug 2021.

First highway trip, less than 500 klms on the clock when I left. Running 91 Octane with air temp of 75 F, it was at 18.1 mpg part way round the loop, got to 18.3 by end of loop. 2500 Laramie crew long box, 18" Firestone ATs, 6.4 with 3.73s.



So with 7000 klms on the truck, city, highway and about 3500 klms hunting on real bad roads in 4x4 both low and high range the hand tabulated average of all fills currently sits at 16.35 mpg. Best mileage. 22.2 mpg over 500 km, worst 12.2, 400 klms with 350 in low range the other 50 in high range. That is a 60% improvement on my V10 under similar use parameters. Didn't really buy it for improved gas mileage but it certainly is a nice fringe benefit.

 

[Doug Ram]

What kind of mileage does a diesel version the Ram 3/4 truck with a crew cab get?

 

[akguy09]

Just curious if you have 3.73's or 4.10's? Also your going to complain about gas mileage but you put 35's on so....

 

[Phirebeard]

I'm getting around 15 in the winter and 17-18 in the summer with my Hemi 1500. Stock tire size, front leveled and a tri-fold hard tonneau cover. The 2003 Montero Sport my Ram replaced got about 17 with its 3.5 V6 if that makes you feel better lol.

Appreciate the replies! MPG shock has definitely subsided a bit. Clearly I'm chaulking this up to a learning experience. I went with the 4.10 because I thought I NEEDED it for the 6-7k lb trailer I tow. As I mentioned I generally pull it and drop it for extended periods of time. I wasn't thinking of how it(4.10) would affect MPG. I just knew it was better for pulling. And yeeeesss I did put 35s on it, because it looks fantastic. Though, if the Night edition package came on it to begin with, I would be riding on factory tires. But because my heart was telling me I wanted the Night Edition, I spent a stupid amount of money blacking the thing out myself, by buying all of the badging, wheels and tires, grille etc. and then paying the dealer to put it on. Thats a totally separate topic....

I do have a question...I truly believe the 3.73 woud be plenty for what I do. (all kidding aside the 1500 woud be plenty) After running the numbers of parts and labor to switch to the 3.73 ($1500), it looks like I'd recoupe that cost after the first year. Is it resaonable to think I'd see 3-5 mpg improvement? If so, it seems like it woud be a no brainer for my situation. Unless there is something I'm not thinking of?

Again totally appreciate everyones input!

Not going to happen. At 65 mph 4:10s run 160 rpm higher in 8th than the 3.73. My 3.73 are doing 1600 rpm at 65 so your 4.10s should be 1760 with 33 tires. With you 35s you are probably close to 1600 already. . See picture above. People get way over involved in a gear ratio difference that means basically nothing. We aren't running 3 or 4 speed automatics anymore.
