In shock and a migrane!!

[olyelr]

A 3 day trip to eastern wyoming and back to the west side. Crossed 3 mountain ranges, battled wind, snow, 65 to 75 mph speed limits, morning temps in the single digits warming into the 30s. 2014 with 4.10's. The 6.4 is most efficient when temps above 50. Wish I had the 8 speed when towing and climbing alot of grades, otherwise it's fine.

Yea. You and i both. That is the only thing i struggle with about my truck. If i could easily slip an 8 speed in it would be my perfect truck.

I usually average about 11-12 with mine with typical grocery gitter type driving.

I must be way out of reality. I had no idea there was winter gas and summer gas. I knew there was for diesel fuel. But I will say I have a mega cab hemi at 7200lbs. I built a nice 6.4L and if I tow I'm lucky when I get over 7mpg if I run 70mph with out a trailer I can only get about 14mpg

 

[Schuie]

I get 24 mpg on the highway with the Cummins in SW Virginia, 2019 Big Horn, Crew Cab Long Bed, 3500. It took about 10,000 miles to get there.
It will get better.

I had a 2021 5.7 Hemi Limited. Mileage was not its long suit. It was a little better at 5k (14.6 mpg). Traded it off at 7200 mi. Used car manager told me "If you drive a hemi, you have to feed a hemi". That pretty well says it. I now have a 3.6 v6 and are in the 18 to 20 mpg and still breaking it in.

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….

Yeah,the EPA doesn't require the companies to post mpg on 2500+. I average 13.5 city/highway combined with my '07 5.9 Cummins with 4.10's and 2200# popup mounted. Diesel's $5/gallon in San Diego thanks to the taxpayers voting for the gas tax scam here. It will always go up and is tied to inflation. Oh boy. The party of the downtrodden has been killing the blue collar and low income citizens here forever.

 

[Regcabguy]

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

Until the credit card bill comes at the end of the month.

 

[MN2500]

It's a 2021 2500 Laramie with a 6.7l Cummins here that I got a year ago tomorrow. The lowest mpg is about 10 in and around here in St. Charles, MN and the highest is 21 on the highway with the cruise set an 70mph.

Two very salient points from this discussion: Break-in takes a long time with a modern engine, and slowing down from 80 to 70 on the highway makes a big difference in fuel mileage. You're pushing a brick through the air, and air resistance is nonlinear. I forget all the formulas, but going 10% faster might take 25-30% more power, or something like that.

Not to be a smart pants if your worried about gas mileage in your truck, you should be driving something else, my ‘18 4x4 CC with3.92 gears and 8 spd. trans 13-15 city in the winter 17-19 city

 

[MN2500]

Even the worst MPGs you guys are getting in your heavy duty trucks (gas or diesel) are so much better than the godawful gas Ford 350 I drove 30+ years ago for a construction company.

I had a 1991 F350 with a Centurion conversion package on it that my Dad gave me right before he died in 2005. My son eventually got it. It had the 7.3 and a five speed manual and could get 17mpg on the highway.

 

[danoday]

Stock, no mods, 2019 2500 power wagon w/55k miles. I have never seen better than 13.2 mpg on my truck since new. I typically avg 12.5 on my daily drive. Mpg doesn’t bother me, but cost per gallon has doubled since 2019. For what it’s worth, my 2015 silverado 4x4 1500 was getting 17mpg and my 2007 ML350 6cyl gets 18 mpg. $3.50 a gallon for the cheap gas sucks not the vehicles

This is a 55 mile ride 2022 ram 2500 diesel .

Yep, I might get 24mpg at 40 mph myself!

 

[Maui Time]

I have about 1,300 miles on my 2022 PW. At highway speeds I am averaging about 15mpg. In town, around 11. I have towed about 5,500lbs twice on the highway for about 200 miles each time. I typically drive slower when towing and have averaged about 10.5mpg while towing.

 

[malonerory]

My work truck is a 2018 2500 5.7 Ram regular cab long bed with 35's. I have never seen anything over 15 mpg. This was achieved on a 50 mile unloaded trip at 70 on the freeway. Average right now on the truck is 10.2. I use it for work so I drive in mixed conditions. Stock tires were on the truck from when I bought it to when I drove it to the tire shop for the 35's, a 2 mile trip the day I bought it. Dealer wanted $5K for a rim and tire package. Speedo was recalibrate at dealer before I left for 35's. Ram is not known for their mileage, anyone who owns one will tell you. My 2020 Diesel averages 12 but I really only use it on the weekend and it most of the time it is towing a toy hauler. When I drive the Diesel without towing I can get around 20-22 on the freeway if I keep it around 65-70. Just enjoy the truck and try not to worry about mileage.

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.

My brother bought chevy years ago. He didnt like it told dealer to take it back. He got his ford truck back. Just a idea, I love my 1500 Ram I get 15 to 20 mpg on freeway less if pulling something.

Op 35” tires, I would keep the 4.10 cause your adding more rolling resist compared to the factory firestone junk tires, 3.73 would be good for those factory tires but 4.10 will help your truck stay in 8th gear longer. Also get your speedo recalibrated for those tires. Also in these trucks with a aerodynamic of a brick, speed kills MPG…I get 10 around town and 15 max on the highway but I’m cooking down the road doing 80 or so…damn NJ traffic

I went from a '16 F-150 XLT SPORT CREW with the 5.0 and had to upgrade to our 2020 RAM 2500 Tradesman 6.4L Hemi to pull our 8K Grand Design RV trailer. The weights were just inside the max #'s but, we absolutely loved the truck. I could get 17-18 driving and the wife was getting about 14 mpg. Pulling our older 6.5K trailer we'd get about 8-9 mpg, running 62-68 average.

We got the RAM a week before our 6 week RV trip from Texas through MO, AR, & PA, to our destination in NJ. Basically broke the motor in pulling the GD trailer in the mountains, and was getting about 7 to the gallon. Once we left Jersey and started south along the East Coast, our mileage started to increase. Overall, trailer/no-trailer was right at 9 mpg, leaving NJ. Rode south to Jacksonville, and across I-10 back to Austin, and overall jumped up to 10.2 mpg. We got the RAM because we do a lot of towing the RV, which now averages over 10 mpg, just depending on conditions.

In the middle of March, we're off again on a trip to MO, AR, and back trough East Texas to a camping rally. Unfortunately, the mpg is just the price you pay for being able to tow 8-10K of trailer SAFELY. Our 150 COULD have done it, but it would have caused so much excessive wear & tear, it would have killed the truck in a couple of years.

Another factor is your Laramie package, which adds probably close to 1K to your curb weight. Our moderately optioned Tradesman with the OFF-ROAD PKG, tips the scale empty right at 7200#. Looking at the numbers a remember while researching RAM's, a Laramie curbs at close to 7900#, which is something you're constantly pulling before you even sit behind the wheel. Our payload is 3,187# which is the main reason I got our truck. Everything is a trade-off when you spec a truck for a specific job. I'd love 15 mpg pulling the trailer, but I know that's no feasible, so I keep stuffing $$$$ in the little round hole on the side of the truck.

Drive gently. Use the correct fuel. Take actual miles driven divided by gallons used beginning with a full tank, using same fill regimen each time. That’s going to give you the magic number, for better or worse. What gear ratio are you pulling? Those 35s are not a fuel mileage tire. Steady state highway or around town? Keep your foot out of it on the road - 70-75 mph is your max best sweet spot. If you’re not towing consistently, go back to a 150/1500, get a couple of Mpg better economy, and move on with life. I’d say you’ll grow into it as long as you need the capabilities of the rig. Good luck.

2022 2500 Laramie just hit 2,200 miles. 8.6 in town, 10.2 highway. Hope it gets better.. when I tow 7k lbs it drops to 7.5
